Absolute paths to Trigger.io assets? - trigger.io

We're building a Trigger app with Chaplin underneath. It would be nice, for development purposes, if we could use absolute paths to our assets, a la:
<link rel="stylesheet" href="/_forge/stylesheets/app.css">
<script src="/_forge/javascripts/vendor.js"></script>
<script src="/_forge/javascripts/app.js"></script>
Is it possible to do this in Trigger?

Unfortunately different platforms have different URLs on Trigger (due to them having their own features and limitations).
If you want to get absolute paths you can use the file module and do something along the lines of:
forge.file.getLocal("js/app.js", function (file) {
forge.file.URL(file, function (url) {
$('body').append('<script src="'+url+'"></script>');
});
});
I'm not sure why an absolute path is useful though, I would recommend only using one html page (index.html) as navigating to a new page is slower on the phone than changing the dom using javascript. In which case all of your relative paths should always be the same.

The easiest thing might be to detect the whether or not forge is present in your index.html and load the javascript accordingly:
<script type="text/javascript">
function addScript(src, callback) {
var tag = document.createElement('script');
tag.type = 'text/javascript';
tag.src = src;
tag.onload = callback;
document.getElementsByTagName('head')[0].appendChild(tag);
}
var vendor = "javascripts/vendor.js";
var app = "javascripts/app.js";
if(window.forge === undefined) {
vendor = "/"+vendor;
app = "/"+app;
}
addScript(vendor, function() {
addScript(app, function() {
require('initialize');
});
});
</script>

How to read/intercept JavaScript on the page before it is executed?

I would like to intercept location.reload(); via a Firefox API or by reading the JS on the page (remote & embedded) before it is loaded/executed or by any other means possible.
Example:
<head>
<script>
window.setTimeout(function() { location.reload(); }, 10000);
</script>
</head>
I have tried beforescriptexecute event listener (via GreaseMonkey & // #run-at document-start) but it is fired AFTER above is executed.
Update:
beforescriptexecute works nicely on REMOTE scripts since the event beforescriptexecute is fired before making the request (but then on the script src and not script content). It is different if the script is within normal script tag (and not remote), as per the example given. The beforescriptexecute fires and the script content can be rewritten but by then the window.setTimeout() has already fired and it is executing.
The beforescriptexecute should work. Its a non-greasemonkey event:
https://developer.mozilla.org/en-US/docs/Web/Events/beforescriptexecute
You can do stuff like this:
document.addEventListener("beforescriptexecute", function(e) {
src = e.target.src;
content = e.target.text;
if (src.search("i18n.js") > -1) {
// Stop original script
e.preventDefault();
e.stopPropagation();
window.jQuery(e.target).remove();
var script = document.createElement('script');
script.textContent = 'script you want';
(document.head || document.documentElement).appendChild(script);
script.onload = function() {
this.parentNode.removeChild(this);
}
}

Youtube API, gapi is not defined?

I'm trying to do a Youtube API and I feel like I got everything working except this gapi and res thing? It says gapi is not defined. How can I make this work?
function tplawesome(e,t){res=e;for(var n=0;n<t.length;n++){res=res.replace(/\{\{(.*?)\}\}/g,function(e,r){return t[n][r]})}return res}
$(function() {
$("form").on("submit", function(e) {
e.preventDefault();
// prepare the request
var request = gapi.client.youtube.search.list({
part: "snippet",
type: "video",
q: encodeURIComponent($("#search").val()).replace(/%20/g, "+"),
maxResults: 3,
order: "viewCount",
publishedAfter: "2015-01-01T00:00:00Z"
});
// execute the request
request.execute(function(response) {
var results = response.result;
$("#results").html("");
$.each(results.items, function(index, item) {
$.get("tpl/item.html", function(data) {
$("#results").append(tplawesome(data, [{"title":item.snippet.title, "videoid":item.id.videoId}]));
});
});
resetVideoHeight();
});
});
$(window).on("resize", resetVideoHeight);
});
function resetVideoHeight() {
$(".video").css("height", $("#results").width() * 9/16);
}
function init() {
gapi.client.setApiKey("AIzaSyD646m4ZfK5yKBZj9p95LohN-PTUnRHBRY");
gapi.client.load("youtube", "v3", function() {
});
}
gapi is an object created by the Google API javascript library that manages all interactions (i.e. does all the heavy lifting of the requests) for you. If the object is not defined, you may not have included the library itself in your page. Somewhere in your HTML, you'll need a script tag that loads the library located at:
https://apis.google.com/js/client.js
Note that, in loading the library with a script tag, you should also pass it a callback ... this is a function that will be automatically called as soon as the library is done loading. So in your case, your init() method is that callback, and so your script tag would look like this:
<script src="https://apis.google.com/js/client.js?onload=init"></script>
The browser will get the library, load it, then run init() when the library is done loading, and all will be ready for your form to execute when triggered.

Dynamic change language in yandex maps

I need to change language in yandex maps, but I don't know how do it!
Language in yandex maps can be changed static in script tag.
<script src="http://api-maps.yandex.ru/2.1/?lang=ru_RU&load=package.full"></script>
But I need to change language in running application.
For example, google maps have loader:
HTML Code
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
JavaScript Code
google.load('maps', '3.7', {
'other_params' : 'sensor=true&language=' + langCode,
'callback' : deviceReadyFunc
});
In yandex maps I have not found.
Solve this problem with localStorage and dynamic adding script-tag.
JavaScript Code
var script=document.createElement('script');
if (GLOBAL_LANGUAGE === 'en') {
script.src = 'http://api-maps.yandex.ru/2.1/?lang=en-US&load=package.full';
} else {
script.src = 'http://api-maps.yandex.ru/2.1/?lang=ru-RU&load=package.full';
}
document.getElementsByTagName('body')[0].appendChild(script);
script.onload = function() {
ymaps.ready(init);
};
In running application after change localStorage variable GLOBAL_LANGUAGE I call reloadApp() method:
reloadApp: function() {
location.href = '#home';
location.reload();
}
After this actions yandex maps change language in running application.

Phonegap and jquery mobile : a href -> Origin null is not allowed by Access-Control-Allow-Origin

Im trying to use jquery mobile with phonegap, in a multi-page document.
Tring to use basic href links within the document, gives the Origin null is not allowed by Access-Control-Allow-Origin error which is quite annoying.
This is because the index page is refered to via file:// rather than http:// which webkit interprets as origin null. Has anyone got jquery mobile and phonegap to work in a multi page environment? if so how can you do it? If you add rel=external to the href tags the links work, but of course all the transitions are lost.
Cant find any info on this specific problem on stack overflow or teh internetz.

Here's the official documentation on how to do just what you are looking for...
Hope this helps!
Leon's comment is the correct answer - you need to add rel="external" to static links.
To Test
Download mongoose http server
copy mongoose_xxxxxxx.exe file to your assets/www
Now you can design your html pages for jquery mobile without Access-Control-Allow-Origin
I think you can find the solution here: http://view.jquerymobile.com/master/demos/faq/how-configure-phonegap-cordova.php
$.mobile.allowCrossDomainPages = true;
$.support.cors = true;
$.mobile.phonegapNavigationEnabled = true
Although I have not gotten it to work, I think that here are the solution.
if you are targeting app above JELLY_BEAN(API Level 16), here is what you can add to MainActivity class.
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN) {
super.appView.getSettings().setAllowUniversalAccessFromFileURLs(true);
}
Which will allow null origin XHR requests.

How to add upload utility to wmd editor?

Has anyone succeeded to do this?
I accomplished this by replacing Util.prompt with my own jquery.dialog method. The prompt function takes a parameter as a callback, making it easy to create a drop-in replacement.
if (isImage) {
// OLD: util.prompt(imageDialogText, imageDefaultText, makeLinkMarkdown);
// WMD_IMAGE_GALLERY_URL loaded from a global settings elsewhere
util.imageGallery(WMD_IMAGE_GALLERY_URL, makeLinkMarkdown);
}
else {
util.prompt(linkDialogText, linkDefaultText, makeLinkMarkdown);
}
If you're interested, I wrote a blog entry about it (with pictures!) which has some more sample code as well as some of the problems/solutions I encountered in implementing this.
The following hack requires use of jQuery, jQuery UI and Mike Alsup's jQuery Form Plugin for performing AJAX file uploads. The hack works with the linked versions (jQ 1.7.2 and jQUI 1.8.20). I can't guarantee compatibility with other versions.
In your <head>, you'll need to include the dependencies:
<script type='text/javascript' src='jquery.min.js'></script>
<link href='theme/jquery-ui.css' rel='stylesheet' type='text/css' />
<script type='text/javascript' src='jquery-ui.js'></script>
<script type='text/javascript' src='wmd/showdown.js'></script>
<script type='text/javascript' src='wmd/wmd.js'></script>
<link type='text/css' rel='stylesheet' href='wmd/wmd.css'/>
<script type='text/javascript' src='jquery.form.js'></script>
We actually need to make a single change to wmd.js.
Go on in there and search (ctrl+f) for var form = doc.createElement("form");
Immediately following this line, assign the form an id, dialogform will do: form.id = "dialogform";
Now on the front end, run:
$(document).ready(function(){
$("#wmd-image-button").live("click",function(){
setTimeout(function(){
$(".wmd-prompt-dialog").css({"opacity": "0", display: "none"});
}, 100);
var $div = $("<div>");
var $form = $("<form>").attr({action: "submit_image.php", method: "post"})
var $file = $("<input/>").attr({type: "file", name: "image"});
var $name = $("<input/>").attr({type: "text", name: "name", placeholder: "Name"});
var $submit = $("<input/>").attr("type", "submit");
$form.append($name, $file, $submit).ajaxForm(function(r) {
r = $.parseJSON(r);
if(r.success){
$("#dialogform input[type='text']").val(r.filename);
$("#dialogform input[value='OK']").trigger("click");
$div.dialog("close");
}
});
$div.append($form).dialog({title: "Upload Image"});
});
$("#wmd-link-button").live("click", function(){
setTimeout(function(){
$(".wmd-prompt-dialog").css("opacity", "1");
}, 100);
});
});
Remember, the post was written for jQuery 1.7.2, and live() has since been deprecated. Please switch to on() if you're using a more recent version of jQuery
And on the backend, in submit_image.php:
$f = $_FILES['image'];
$p = $_POST;
$allowedTypes = array(IMAGETYPE_PNG, IMAGETYPE_JPEG, IMAGETYPE_GIF);
$detectedType = exif_imagetype($f['tmp_name']);
if(in_array($detectedType, $allowedTypes)){
$pi = pathinfo($f['name']);
$ext = $pi['extension'];
$target = "img/" . strtolower(str_replace(" ", "-", $p['name'])) . "." . $ext;
if(move_uploaded_file($f['tmp_name'], $target)){
$returnArr = array(
"success" => true,
"filename" => site_url($target)
);
echo json_encode($returnArr);
}
else echo json_encode(array("success" => false));
}
else echo json_encode(array("success" => false, "msg" => "Invalid File Type."));
Hopefully that will get you started. This was written a couple of years ago, when my javascript skills were sub-par! Haha. I previously had this on a blog (which is now dead), with step-by-step instructions and explanations; lots of unnecessary fluff. Thanks #Kamiccolo for bringing this link to my attention. I had to consult the way-back-machine in order to revive it.
Add a button to the control panel of WMD.
Search for the following string to find the place where buttons are being added:
italicButton.XShift
In my version, the function is in class SpritedButtonRow and is called build.
Ignore the setup and textOp attributes. XShift is the position of the button image in the css sprite that comes with WMD, Instead of that, give the button a class and in the class specify the background image. Then Just add an onclick event to the button
that will do what you need it to do.
But, I don't think an upload button should be inside a text editor, does not make sense.
