I have a script here, which is extracting the links within a web page. It is comming back with the error 'content is not defined'.
// extract the links
var links = new Array();
for (i = 0; i < content.document.links.length; i++) {
var thisLink = content.document.links[i].toString();
//links.push(content.document.links[i].toString());
console.log(thisLink);
}
In order to interact with the HTML documents within the Firefox SDK, do I need to import a library?
It depends on when the self executing anonymous function is running. It is possible that it is running before window.document is defined.
In that case, try adding a listener
window.addEventListener('load', yourFunction, false);
// ..... or
window.addEventListener('DOMContentLoaded', yourFunction, false);
yourFunction () {
// some ocde
}

____ INTRO
Hello everyone, first of all, three clarifications:
My english is not good, so I beg your pardon in advance for my mistakes,
I'm a newbie so forgive me for inaccuracies,
I have previously searched and tried the solutions I found on the internet but still I can not solve the problem of embedding a prepopulated database.
____ THE GOAL
I want to develop an app for iOS and Android with a prepopulated database.
Just for example, the database consists of 15.000 records each one made of three key-value pair (id, firstname and lastname).
___ WHAT I DID
Steps:
ionic start myapp blank
cd myapp
ionic platform add ios
ionic platform add android
Then I created an sqlite database for testing purpose, named mydb.sqlite, made of one table people containing two id, firstname, lastname records.
I decided to use the following plugin: https://github.com/Antair/Cordova-SQLitePlugin
That's because it can be installed with cordova tool.
ionic plugin add https://github.com/Antair/Cordova-SQLitePlugin
(Alert: I think that the instructions on the website show an incorrect reference - "cordova plugin add https://github.com/brodysoft/Cordova-SQLitePlugin" - which refers to another plugin).
Then, following the instructions on the plugin website, I copied the database to myapp/www/db/ so that it can now be found at myapp/www/db/mydb.sqlite
I modified the index.html including the SQLite plugin just after the default app.js script:
<!-- your app's js -->
<script src="js/app.js"></script>
<script src="SQLitePlugin.js"></script>
I also write some lines of code in index.html file to show a button:
<ion-content ng-controller="MyCtrl">
<button class="button" ng-click="all()">All</button>
</ion-content>
Finally I had modified ./js/app.js:
// Ionic Starter App
var db = null;
angular.module('starter', ['ionic' /* What goes here? */ ])
.run(function($ionicPlatform) {
$ionicPlatform.ready(function() {
// some predefined code has been omitted
window.sqlitePlugin.importPrepopulatedDatabase({file: "mydb.sqlite", "importIfExists": true});
db = window.sqlitePlugin.openDatabase({name: "mydb.sqlite"});
}); // $ionicPlatform.ready
}) // .run
.controller('MyCtrl', function($scope){
$scope.all = function(){
var query = "SELECT * FROM people";
// I don't know how to proceed
}; // $scope.all
}); // .controller
___ THE PROBLEM
I don't know how to proceed in the controller section to query all the records (just an example of query) and show the results in the console.log.
I think that the following code must be completed in some way:
angular.module('starter', ['ionic' /* What goes here? */ ])
And also the code inside controller section must be completed:
$scope.all = function(){
var query = "SELECT * FROM people";
// I don't know how to proceed
}; // $scope.all
___ FINAL THANKS
Thank you in advance for the help you will give to me.
So this guy's code has helped a lot to encapsulate my DAL. I highly recommend that you use he's code pretty much verbatim.
https://gist.github.com/jgoux/10738978
You'll see he has the following method:
self.query = function(query, bindings) {
bindings = typeof bindings !== 'undefined' ? bindings : [];
var deferred = $q.defer();
self.db.transaction(function(transaction) {
transaction.executeSql(query, bindings, function(transaction, result) {
deferred.resolve(result);
}, function(transaction, error) {
deferred.reject(error);
});
});
return deferred.promise;
};
Let's break this down a bit. The query function takes a query string (the query param) and a list of possible bindings for ? in a query like "SELECT * FROM A_TABLE WHERE ID = ?". Because he's code is a service, the self value points to the service itself for all future invocations. The function will execute a transaction against the db, but it returns a promise that is only fulfilled once the db comes back.
His service provides a second helper function: fetchAll.
self.fetchAll = function(result) {
var output = [];
for (var i = 0; i < result.rows.length; i++) {
output.push(result.rows.item(i));
}
return output;
};
fetchAll will read the rows in their entirety into an array. The result param for fetchAll is the result variable passed in the query function's promise fulfillment.
If you copy and paste his code into your service file, you now have a bonafide DB service. You can wrap that service up in a DAL. Here's an example from my project.
.service('LocationService', function ($q, DB, Util) {
'use strict';
var self = this;
self.locations = [];
self.loadLocked = false;
self.pending = [];
self.findLocations = function () {
var d = $q.defer();
if (self.locations.length > 0) {
d.resolve(self.locations);
}
else if (self.locations.length === 0 && !self.loadLocked) {
self.loadLocked = true;
DB.query("SELECT * FROM locations WHERE kind = 'active'")
.then(function (resultSet) {
var locations = DB.fetchAll(resultSet);
self.locations.
push.apply(self.locations, locations);
self.loadLocked = false;
d.resolve(self.locations);
self.pending.forEach(function (d) {
d.resolve(self.locations);
});
}, Util.handleError);
} else {
self.pending.push(d);
}
return d.promise;
};
})
This example is a bit noisy since it has some "threading" code to make sure if the same promise is fired twice it only runs against the DB once. The general poin is to show that the DB.query returns a promise. The "then" following the query method uses the DB service to fetchAll the data and add it into my local memory space. All of this is coordinated by the self.findLocations returning the variable d.promise.
Yours would behalf similarly. The controller could have your DAL service, like my LocationService, injected into it by AngularJS. If you're using the AngularJS UI, you can have it resolve the data and pass it into the list.
Finally, the only issue I have with the guy's code is that the db should come from this code.
var dbMaker = ($window.sqlitePlugin || $window);
The reason for this is that the plugin does not work within Apache Ripple. Since the plugin does a fine job mirroring the Web SQL interface of the browser, this simple little change will enable Ripple to run your Ionic Apps while still allowing you to work your SQLite in a real device.
I hope this helps.
I am creating a firefox addon using the SDK. My goal is simple, to intercept a specific iframe and load my own HTML page (packaged as a resource with my addon) instead of the content that was requested originally.
So far I have the following code:
var httpRequestObserver =
{
observe: function(subject, topic, data)
{
var httpChannel, requestURL;
if (topic == "http-on-modify-request") {
httpChannel = subject.QueryInterface(Ci.nsIHttpChannel);
requestURL = httpChannel.URI.spec;
var newRequestURL, i;
if (/someurl/.test(requestURL)) {
var ioService = Cc["#mozilla.org/network/io-service;1"].getService(Ci.nsIIOService);
httpChannel.redirectTo(ioService.newURI(self.data.url('pages/test.html'), undefined, undefined));
}
return;
}
}
};
var observerService = Cc["#mozilla.org/observer-service;1"].getService(Ci.nsIObserverService);
observerService.addObserver(httpRequestObserver, "http-on-modify-request", false);
This code works in that it detects the proper iframe loading and does the redirect correctly. However, I get the following error:
Security Error: Content at http://url.com may not load or link to
jar:file:///.../pages/test.html.
How can I get around this limitation?
actually man i was really over thinking this.
its already solved when I changed to using loadContext. Now when you get loadContext you get the contentWindow of whatever browser element (tab browser, or frame or iframe) and then just abort the http request like you are doing and then loadContext.associatedWindow.document.location = self.data('pages/tests.html');
done
ill paste the code here removing all the private stuff. you might need the chrome.manifest ill test it out and paste the code back here
Cu.import('resource://gre/modules/Services.jsm');
var httpRequestObserver = {
observe: function (subject, topic, data) {
var httpChannel, requestURL;
if (topic == "http-on-modify-request") {
httpChannel = subject.QueryInterface(Ci.nsIHttpChannel);
requestURL = httpChannel.URI.spec;
var newRequestURL, i;
if (/someurl/.test(requestURL)) {
var goodies = loadContextGoodies(httpChannel);
if (goodies) {
httpChannel.cancel(Cr.NS_BINDING_ABORTED);
goodies.contentWindow.location = self.data.url('pages/test.html');
} else {
//dont do anything as there is no contentWindow associated with the httpChannel, liekly a google ad is loading or some ajax call or something, so this is not an error
}
}
return;
}
}
};
Services.obs.addObserver(httpRequestObserver, "http-on-modify-request", false);
//this function gets the contentWindow and other good stuff from loadContext of httpChannel
function loadContextGoodies(httpChannel) {
//httpChannel must be the subject of http-on-modify-request QI'ed to nsiHTTPChannel as is done on line 8 "httpChannel = subject.QueryInterface(Ci.nsIHttpChannel);"
//start loadContext stuff
var loadContext;
try {
var interfaceRequestor = httpChannel.notificationCallbacks.QueryInterface(Ci.nsIInterfaceRequestor);
//var DOMWindow = interfaceRequestor.getInterface(Components.interfaces.nsIDOMWindow); //not to be done anymore because: https://developer.mozilla.org/en-US/docs/Updating_extensions_for_Firefox_3.5#Getting_a_load_context_from_a_request //instead do the loadContext stuff below
try {
loadContext = interfaceRequestor.getInterface(Ci.nsILoadContext);
} catch (ex) {
try {
loadContext = subject.loadGroup.notificationCallbacks.getInterface(Ci.nsILoadContext);
} catch (ex2) {}
}
} catch (ex0) {}
if (!loadContext) {
//no load context so dont do anything although you can run this, which is your old code
//this probably means that its loading an ajax call or like a google ad thing
return null;
} else {
var contentWindow = loadContext.associatedWindow;
if (!contentWindow) {
//this channel does not have a window, its probably loading a resource
//this probably means that its loading an ajax call or like a google ad thing
return null;
} else {
var aDOMWindow = contentWindow.top.QueryInterface(Ci.nsIInterfaceRequestor)
.getInterface(Ci.nsIWebNavigation)
.QueryInterface(Ci.nsIDocShellTreeItem)
.rootTreeItem
.QueryInterface(Ci.nsIInterfaceRequestor)
.getInterface(Ci.nsIDOMWindow);
var gBrowser = aDOMWindow.gBrowser;
var aTab = gBrowser._getTabForContentWindow(contentWindow.top); //this is the clickable tab xul element, the one found in the tab strip of the firefox window, aTab.linkedBrowser is same as browser var above //can stylize tab like aTab.style.backgroundColor = 'blue'; //can stylize the tab like aTab.style.fontColor = 'red';
var browser = aTab.linkedBrowser; //this is the browser within the tab //this is where the example in the previous section ends
return {
aDOMWindow: aDOMWindow,
gBrowser: gBrowser,
aTab: aTab,
browser: browser,
contentWindow: contentWindow
};
}
}
//end loadContext stuff
}
NOTE: Now try this first, I didn't test it yet, if you get a security error when it tries to redirect then create a chrome.manifest file and put it in the root directory. If it throws a security error than you definitely need a chrome.manifest file and that will without question fix it up. I'll test this myself later tonight when I get some time.
The chrome.manifest should look like this:
content kaboom-data ./resources/kaboom/data/ contentaccessible=yes
Then in the code way above change the redirect line from goodies.contentWindow.location = self.data.url('pages/test.html'); to goodies.contentWindow.location = 'chrome://kaboom-data/pages/test.html');.
see this addon here: https://addons.mozilla.org/en-US/firefox/addon/ghforkable/?src=search
in the chrome.manifest file we set the contentaccessible parameter to yes
you dont need sdk for this addon. its so simple, just ocpy paste that into a bootstrap skeleton as seen here:
Bootstrap With Some Features, Like chrome.manifest which you will need
Bootstrap Ultra Basic
if you want to really do a redirect of a page to your site, maybe you want to make a custom about page? if you would like ill throw togather a demo for you on making a custom about page. you can see a bit hard to understand demo here
posting my trials here so it can help all:

CONCLUSION
in both trials above it was the weirdest thing, it wouldnt show the resource or chrome path in the security error thrown but it would give the full jar path. Leading me to believe that this has something to do with redirectTo function.
The solution that did work was your solution of
var gBrowser = utils.getMostRecentBrowserWindow().gBrowser;
var domWin = httpChannel.notificationCallbacks.getInterface(Ci.nsIDOMWindow);
var browser = gBrowser.getBrowserForDocument(domWin.document);
//redirect
browser.loadURI(self.data.url('pages/test.html'));
however I changed this to use loadContext instead of this method because it is the recommended way. also gBrowser to getMostRecentBrowserWindow will fail if the url load is slow and in that time the user swithces to another tab or window
I also changed to use Services.jsm as you had imported Cu anyways. Using Services.jsm is super fast not even blink fast. Its just a pointer.
Im still working on trying to the redirectTo method working its really bothering me. The changes I made are to my local copy.
Have you considered turning your local HTML file into a data URL and loading that?
I'm working on a firefox extension, until now I was working with XUL browser, to control the user navigation across web sites and save the visited pages, but the browser is limited, I tried a simple google search, when I click on some result, it won't be displayed in the browser.
One idea is to move the xul application to Dialog and control the actual firefox tabs.
But I have no idea how to do this.
(per your comment....)
To create an addon that logs TAB 'load' events, create a bootstrapped (restartless) addon:
bootstrap.js (The JavaScript file containing your 'privileged' code)
install.rdf (an XML file describing your addon to Firefrox)
To build the addon, simply place both files inside the top-level (no folders!) of a ZIP file with the file extension .xpi. To install the addon, navigate to about:addons then from the tools menu, click Install from file, find your XPI, open it, then after a short delay choose Install.
In install.rdf put something like this:
<?xml version="1.0"?>
<RDF xmlns="http://www.w3.org/1999/02/22-rdf-syntax-ns#"

You need to implement two mandatory JavaScript functions in the bootstrap.js:
startup() - called when you install the addon, and when your browser starts up.
shutdown() - called when you uninstall the addon, and when your browser shuts down.
You should call all of the 'privileged' code from startup(). For hygiene, you can (and probably should) also implement install() and uninstall() functions.
Start by implementing the following code in bootstrap.js:
const Cc = Components.classes;
const Ci = Components.interfaces;
let consoleService = Cc["#mozilla.org/consoleservice;1"]
.getService(Ci.nsIConsoleService);
let wm = Cc["#mozilla.org/appshell/window-mediator;1"]
.getService(Ci.nsIWindowMediator);
function LOG(msg) {
consoleService.logStringMessage("EXTENSION: "+msg);
}
function startup() {
try {
LOG("starting up...");
let windows = wm.getEnumerator("navigator:browser");
while (windows.hasMoreElements()) {
let chromeWindow = windows.getNext().QueryInterface(Ci.nsIDOMWindow);
WindowListener.setupBrowserUI(chromeWindow);
}
wm.addListener(WindowListener);
LOG("done startup.");
} catch (e) {
LOG("error starting up: "+e);
}
}
function shutdown() {
try {
LOG("shutting down...");
let windows = wm.getEnumerator("navigator:browser");
while (windows.hasMoreElements()) {
let chromeWindow = windows.getNext().QueryInterface(Ci.nsIDOMWindow);
WindowListener.tearDownBrowserUI(chromeWindow);
}
wm.addListener(WindowListener);
LOG("done shutdown.");
} catch (e) {
LOG("error shutting down: "+e);
}
}
Basically, that calls WindowListener.setupBrowserUI() for each current & future window of your web-browser. WindowListener is defined as follows:
var WindowListener = {
setupBrowserUI: function(chromeWindow) {
chromeWindow.gBrowser.addEventListener('load', my_load_handler, true);
},
tearDownBrowserUI: function(chromeWindow) {
chromeWindow.gBrowser.removeEventListener('load', my_load_handler, true);
},
onOpenWindow: function(xulWindow) {
let chromeWindow = xulWindow.QueryInterface(Ci.nsIInterfaceRequestor)
.getInterface(Ci.nsIDOMWindow);
chromeWindow.addEventListener("load", function listener() {
chromeWindow.removeEventListener("load", listener, false);
var domDocument = chromeWindow.document.documentElement;
var windowType = domDocument.getAttribute("windowtype");
if (windowType == "navigator:browser")
WindowListener.setupBrowserUI(chromeWindow);
}, false);
},
onCloseWindow: function(chromeWindow) { },
onWindowTitleChange: function(chromeWindow, newTitle) { }
};
That sets up an event listener for the OpenWindow event, and in turn installs an event listener for load events in the TabBrowser of each ChromeWindow. The load event handler is defined as:
var my_load_handler = function (evt) {
try {
var browserEnumerator = wm.getEnumerator("navigator:browser");
while (browserEnumerator.hasMoreElements()) {
var browserWin = browserEnumerator.getNext();
var tabbrowser = browserWin.gBrowser;
var numTabs = tabbrowser.browsers.length;
for (var index = 0; index < numTabs; index++) {
var currentBrowser = tabbrowser.getBrowserAtIndex(index);
var domWindow = currentBrowser.contentWindow.wrappedJSObject;
if (!domWindow.hasOwnProperty('__logged_this_window__')) {
LOG("TAB loaded:");
LOG(" URL: "+domWindow.location.href);
LOG(" TITLE: "+domWindow.title)
domWindow.__logged_this_window__ = 1;
}
}
}
} catch (e) {
LOG(e);
}
}
So basically, if there's a load event on any of the TabBrowser elements in Firefox, that function will run. It'll enumerate all of the Firefox windows, and all of those windows' tabs (Browser elements). The trick is that when a page reloads all the custom properties on a "content" DomWindow are lost, so we check to see if a custom property is present. If not, then we log details of the TAB's content page.
I work on a Windows 8 app, and from a page that I use link hystory for running back and forward through the app, I also have 3 or 4 links to external websites(eg: facebook or my site). I tried to run them in iframe, or also to make them open in the default browser like simple links. Both method resulted in an error in base.js that says it can't handle my error (!?) I searched a lot before asking here. I watched msdn sample that works just fine, but if i copy what I need in my app results in the same error. I I use it from another page where I dont have forward history, it works, but i really need it on the front page. Any ideeas? Thank you very much.

This is my items.js code: ( for the items.html page )
(function () {
"use strict";
var appViewState = Windows.UI.ViewManagement.ApplicationViewState;
var ui = WinJS.UI;
ui.Pages.define("/pages/items/items.html", {
// This function is called whenever a user navigates to this page. It
// populates the page elements with the app's data.
ready: function (element, options) {
var listView = element.querySelector(".itemslist").winControl;
listView.itemDataSource = Data.groups.dataSource;
listView.itemTemplate = element.querySelector(".itemtemplate");
listView.oniteminvoked = this._itemInvoked.bind(this);
this._initializeLayout(listView, Windows.UI.ViewManagement.ApplicationView.value);
listView.element.focus();
WinJS.Utilities.query("a").listen("click", this.linkClickEventHandler, false);
},
// This function updates the page layout in response to viewState changes.
updateLayout: function (element, viewState, lastViewState) {
/// <param name="element" domElement="true" />
var listView = element.querySelector(".itemslist").winControl;
if (lastViewState !== viewState) {
if (lastViewState === appViewState.snapped || viewState === appViewState.snapped) {
var handler = function (e) {
listView.removeEventListener("contentanimating", handler, false);
e.preventDefault();
}
listView.addEventListener("contentanimating", handler, false);
var firstVisible = listView.indexOfFirstVisible;
this._initializeLayout(listView, viewState);
if (firstVisible >= 0 && listView.itemDataSource.list.length > 0) {
listView.indexOfFirstVisible = firstVisible;
}
}
}
},
linkClickEventHandler: function (eventInfo) {
eventInfo.preventDefault();
var link = eventInfo.target;
WinJS.Navigation.navigate(link.href);
},
// This function updates the ListView with new layouts
_initializeLayout: function (listView, viewState) {
/// <param name="listView" value="WinJS.UI.ListView.prototype" />
if (viewState === appViewState.snapped) {
listView.layout = new ui.ListLayout();
} else {
listView.layout = new ui.GridLayout();
}
},
_itemInvoked: function (args) {
var groupKey = Data.groups.getAt(args.detail.itemIndex).key;
WinJS.Navigation.navigate("/pages/split/split.html", { groupKey: groupKey });
}
});
})();
And from items.html I have different types of links: some of them links to other application pages, from where I can return with history buttons back/forward and some of them are links to external page. Simple link.These links crashes my app with the error that I mentioned below. If I erase the next line:
WinJS.Utilities.query("a").listen("click", this.linkClickEventHandler, false);
from my js script, external links works, but I dont have anymore history buttons in my others's app pages.
You are trying to use the navigation framework to navigate to an external URI. It's usually meant to be used within the application's local context and pages that can contain 'fragments' to load up into your main nav control.
I wouldn't hook anchor tags with your function call, instead in your linkClickEventHandler I would do the following to only hook your internal links
WinJS.Utilities.query(".nav").listen("click", linkClickEventHandler, false);
in turn your internal links would be
click me
This approach only hooks the navigation framework into your internal links. Another approach is to inspect the 'this.href' in your handler and if it contains http:// or https:// then call window.open instead
seems to me that I didn't fully understand the concept behind jquerymobile, because I have no idea how to solve this issue.
What I want to do is load some HTML Content via AJAX, according to location.hash, put it into a new page and load this page.
But if I create a page myself by using the pagebeforechange event, jquerymobile just ignores it, creates its own div and my content won't be displayed.
How do I have to do it?
Edit:
This is how I am currently doing it, but it wont't work.
$(function() {
getPageContent(top.location.href, false);
$(document).bind( "pagebeforechange", function( e, data ) {
getPageContent(data.toPage, true);
});
});
function getPageContent(pageUrl, changedPage) {
var re = /.*\/#(.*)/;
var result;
result = re.exec(pageUrl);
window.page = result[1].substr(0,3);
window.id = result[1].substr(3);
window.ajaxUrl = "request.php?page="+window.page+"&id="+window.id;
$.ajax({
url: window.ajaxUrl,
success: function(data) {
if(data.error) {
alert(data.error);
}
else if(data.data) {
if(changedPage) {
changePage(data.data));
}
else {
$('#content[role="main"]').html(atob(data.data));
setupPage();
}
}
else {
alert("UNKNOWN ERROR: "+data);
}
}
});
}
function changePage(html) {
var div = "<div></div>";
var newPage = $(div).attr("data-role", "page").attr("data-url", window.page+window.id);
var header = $(div).attr("data-role", "header");
var content = $(div).attr("data-role", "content");
var footer = $(div).attr("data-role", "footer");
$("body").append(newPage);
newPage.append(header, content, footer);
content.html(html);
newPage.page();
}
Complete edit of the whole answer:
First. Set your body id to id=body. Then when you want to load the new page and change to it, use an ajax call like this:
$.get(window.ajaxUrl, function(data){
$('#body').append("<div id='newPage' data-role='page'></div>"); //Creates a new page.
$('#newPage').html(data); //Loads the html content into the new page.
$.mobile.changePage('#newPage'); //Navigates to the new page.
}
This sends an ajax call with the method GET to the url found in your window.ajaxUrl. If the call is successful, it creates a new page named "newPage", and fills it with the data received from the ajax call. Then redirects to the newly created page.
This jsFiddle shows the basics of how it works. However, it doesn't use any ajax call.
You have to refresh the page with jQueryMobile :
$("#your-page").trigger("create");
--Edit
<script>
$("#thepage").live("pageshow", function(){
$("#thepage).trigger("create");
});
</script>
Change the content of #thepage before 'pageshow' event

Make sure all your pages are decide with unique IDs and data-role='page'. Check out the start guide here:
