I am using offline.js with turbolinks and on initial page load it works fine. But if I click another links then this wont work until I refresh the page. I can see the Offline.state is down but still the view is not showing. Is there any way to manually trigger the popup window?
Update
Other than the offline.js file the only js I have is this
var
$online = $('.online'),
$offline = $('.offline');
Offline.on('confirmed-down', function () {
$online.fadeOut(function () {
$offline.fadeIn();
});
});
Offline.on('confirmed-up', function () {
$offline.fadeOut(function () {
$online.fadeIn();
});
});
This is an old question, but I ran into the same problem, maybe it can help someone.
offline.js creating these dom elements on page load inside the body HTML
<div class="offline-ui offline-ui-up">
<div class="offline-ui-content"></div>
</div>
The reason why offline.js not working after page change is that on-page change the body HTML replaced with the new content returned by the server and the code above removed.
This is how Turbolinks works, so page load will be not triggered and the offline.js dom elements will be not created.
One solution will be to warp the offline.js inside a function and call it on every page change, but it will cause eventually memory leak (as "offline" and "online" event listener will be added to 'window' on each change)
Other solution will be to save the 'offline-ui' HTML before the new page loaded and bring it back after load:
# will fire before page change and save offline.js UI
document.addEventListener("turbolinks:before-render", function() {
if (!document.offlineHtml) {
document.offlineHtml = $('.offline-ui');
}
});
# will fire afterload and will check if there is a UI to append to the body
document.addEventListener("turbolinks:load", function() {
if (document.offlineHtml) {
$(document.body).append(document.offlineHtml);
}
});
At the moment this is the best way that I could find to fix that.
This could be a turbolinks issue. In app/assets/javascripts/application.js, wrap your javascript code within:
$(document).on('turbolinks:load', function() {
// your code
});

Adding my bindings to the pageinit event like so:
$('#mypage').on("pageinit", function () {
$('#login-sumbit').on('click', function () {
console.log('button clicked');
});
});
I would expect pageinit to bind the click event once only. But what happens in my single page app is that the button is binding every time the page is loaded even when clicking back.
This results in undesirable multiple duplicate binds. Any ideas on what event to use to bind only once in my single page app, so that loading the page again (back button, loading inline page) in the same session doesn't re-bind?
Looks like I found the answer myself, turns out quite rightly pageinit fires every time the page is loaded even though it's not reloading from the server, otherwise what would fire when a new page is shown.
pageinit is the right event but I need to use .one not .on, .one will bind one time only.
$('#mypage').on("pageinit", function () {
$('#login-sumbit').one('click', function () {
console.log('button clicked');
});
});
Now everything works as expected. Better still I've found you can use .one with the pageinit event for even more control over your bindings and data loads perfect for my requirements.
http://api.jquery.com/one/
You could use:
$('#login-sumbit').off('click').on('click', function(e) {
console.log('button clicked');
});
I tested on the Apple device, and when I click on the screen when there is no effect. This is my code. Click on the events of this writing there are questions?
<script>
$(function() {
$('#test').tap(function() {
$('#menuNum').text('1');
})
})
</script>
You need to change few things.
Do not use $(function() { or classic document ready to check for a correct state, they can cause problems with jQuery Mobile. Instead use jQuery Mobile alternative called page events.
Then don't bind tap event like that, use proper modern way of doing that. In your case element must be loaded into the DOM for that kind of binding to work. And because of $(function() { sometimes it can happen that element is still loading when binding is executed. So use it like this:
$(document).on('tap','#test',function() {
$('#menuNum').text('1');
});
This method don't care if element exist or not, it will even work if element is loaded into the DOM after binding process.
Working example: http://jsfiddle.net/Gajotres/SQ7DF/
In the end you want something like this:
$(document).on('pagebeforeshow', '#index', function(){
$(document).on('tap','#test',function() {
alert('Tap');
});
});
Unable to call jquery functions in $viewContentLoaded event of Angular controller, here is the code for the same.
$scope.$on('$viewContentLoaded', function() {
jQuery.growlUI('Growl Notification', 'Saved Succesfully');
jQuery('#category').tree()
});
Is any configuration required here?? I tried even noConflict(); var $jq = jQuery.noConflict();
Does it require any other configuration?
Thanks,
Abdul
First thing first, don't do DOM manipulation from controller. Instead do it from directives.
You can do same thing in directive link method. You can access the element on which directive is applied.
Make sure you load jquery before angularjs scripts, then grawlUI, three, angularJS and finally your application script. Below is directive sample
var app = angular.module("someModule", []);
app.directive("myDirective", function () {
return function (scope, element, attrs) {
$.growlUI('Growl Notification', 'Saved Succesfully');
element.tree();
};
});
angularjs has built in jQuery lite.
if you load full jquery after angular, since jQuery is already defined, the full jquery script will skip execution.
==Update after your comment==
I reviewed again your question after comment and realised that content which is loaded trough ajax is appended to some div in your angular view. Then you want to apply element.tree() jquery plugin to that content. Unfortunately example above will not work since it is fired on linking which happened before your content from ajax response is appended to element with directive I showed to you. But don't worry, there is a way :) tho it is quick and dirty but it is just for demo.
Let's say this is your controller
function ContentCtrl($scope, $http){
$scope.trees=[];
$scope.submitSomethingToServer=function(something){
$http.post("/article/1.html", something)
.success(function(response,status){
// don't forget to set correct order of jquery, angular javascript lib load
$.growlUI('Growl Notification', 'Saved Succesfully');
$scope.trees.push(response); // append response, I hope it is HTML
});
}
}
Now, directive which is in controller scope (it uses same scope as controller)
var app = angular.module("someModule", []);
app.directive("myDirective", function () {
return function (scope, element, attrs) {
scope.$watch("trees", function(){
var newParagraph=$("<p>" + scope.trees[scope.trees.length-1] + "</p>" ); // I hope this is ul>li>ul>li...or what ever you want to make as tree
element.append(newParagraph);
newParagraph.tree(); //it will apply tree plugin after content is appended to DOM in view
});
};
});
The second approach would be to $broadcast or $emit event from controller (depends where directive is, out or in scope of controller) after your ajax completes and you get content from server. Then directive should be subscribed to this event and handle it by receiving passed data (data=content as string) and do the rest as I showed you above.
The thing is, threat that content from ajax as data all the way it comes to directive, then inject it to element in which you want to render it and apply tree plugin to that content.
On a page I have an iframe. In this iframe is a collection of items that I need to be sortable. All of the Javascript is being run on the parent page. I can access the list in the iframe document and create the sortable by using context:
var ifrDoc = $( '#iframe' ).contents();
$( '.sortable', ifrDoc ).sortable( { cursor: 'move' } );
However, when trying to actually sort the items, I'm getting some aberrant behavior. As soon as an item is clicked on, the target of the script changes to the outer document. If you move the mouse off of the iframe, you can move the item around and drop it back by clicking, but you can not interact with it within the iframe.
Example: http://robertadamray.com/sortable-test.html
So, is there a way to achieve what I want to do - preferably without having to go hacking around in jQuery UI code?
Dynamically add jQuery and jQuery UI to the iframe (demo):
$('iframe')
.load(function() {
var win = this.contentWindow,
doc = win.document,
body = doc.body,
jQueryLoaded = false,
jQuery;
function loadJQueryUI() {
body.removeChild(jQuery);
jQuery = null;
win.jQuery.ajax({
url: 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/jquery-ui.min.js',
dataType: 'script',
cache: true,
success: function () {
win.jQuery('.sortable').sortable({ cursor: 'move' });
}
});
}
jQuery = doc.createElement('script');
// based on https://gist.github.com/getify/603980
jQuery.onload = jQuery.onreadystatechange = function () {
if ((jQuery.readyState && jQuery.readyState !== 'complete' && jQuery.readyState !== 'loaded') || jQueryLoaded) {
return false;
}
jQuery.onload = jQuery.onreadystatechange = null;
jQueryLoaded = true;
loadJQueryUI();
};
jQuery.src = 'http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js';
body.appendChild(jQuery);
})
.prop('src', 'iframe-test.html');
Update: Andrew Ingram is correct that jQuery UI holds and uses references to window and document for the page to which jQuery UI was loaded. By loading jQuery / jQuery UI into the iframe, it has the correct references (for the iframe, rather than the outer document) and works as expected.
Update 2: The original code snippet had a subtle issue: the execution order of dynamic script tags isn't guaranteed. I've updated it so that jQuery UI is loaded after jQuery is ready.
I also incorporated getify's code to load LABjs dynamically, so that no polling is necessary.
Having played with their javascript a bit, Campaign Monitor solves this by basically having a custom version of jQuery UI. They've modified ui.mouse and ui.sortable to replace references to document and window with code that gets the document and window for the element in question. document becomes this.element[0].ownerDocument
and they have a custom jQuery function called window() which lets them replace window with this.element.window() or similar.
I don't know why your code isn't working. Looks like it should be.
That said, here are two alternative ways to implement this feature:
If you can modify the iframe
Move your JavaScript from the parent document into iframe-test.html. This may be the cleanest way because it couples the JavaScript with the elements its actually executing on.
http://dl.dropbox.com/u/3287783/snippets/rarayiframe/sortable-test.html
If you only control the parent document
Use the jQuery .load() method to fetch the content instead of an HTML iframe.
http://dl.dropbox.com/u/3287783/snippets/rarayiframe2/sortable-test.html
Instead of loading jQuery and jQueryUI inside the iFrame and evaluating jQueryUI interactions both in parent and child - you can simply bubble the mouse events to the parent's document:
var ifrDoc = $( '#iframe' ).contents();
$('.sortable', ifrDoc).on('mousemove mouseup', function (event) {
$(parent.document).trigger(event);
});
This way you can evaluate all your Javascript on the parent's document context.
I have a page that loads and after it loads, it pulls in a list of LIs to populate a news feed.
<li>quick view</li>
<li>quick view</li>
<li>quick view</li>
I'm trying to get fancy box to trigger when a user clicks on quick view but haven't had any luck. Any Ideas?
$(document).ready(function() {
$('.quickview').fancybox();
});
also tried:
$(document).ready(function() {
$('a.quickview').live('click', function() {
$(this).fancybox();
});
});
http://fancybox.net/
Thanks for any ideas...
Old question, but might be useful for future searchers.
My preferred solution is to fire fancybox manually from within the live event, eg:
$('.lightbox').live('click', function() {
$this = $(this);
$.fancybox({
height: '100%',
href: $this.attr('href'),
type: 'iframe',
width: '100%'
});
return false;
});
EDIT: From jQuery 1.7 live() is deprecated and on() should be used instead. See http://api.jquery.com/live/ for more info.
this should work after every ajax request
$(document).ajaxStop(function() {
$("#whatever").fancybox();
});
The problems is to attach fancybox into AJAX loaded element, right?
I got same problems and I found this solution.
I copy paste it here, see the original bug report for more info:
$.fn.fancybox = function(options) {
$(this)
.die('click.fb')
.live('click.fb', function(e) {
$(this).data('fancybox', $.extend({}, options, ($.metadata ? $(this).metadata() : {})))
e.preventDefault();
[...]

Since .on is now recommended over .live, and after reading over the documentation on delegated events, here's a solution I came up with (assuming your elements have a class of 'trigger-modal'):
$(document).on('click', '.trigger-modal', function() {
// remove the class to ensure this will only run once
$(this).removeClass('trigger-modal');
// now attach fancybox and click to open it
$(this).fancybox().click();
// prevent default action
return false;
});
From my understanding of Fancybox, the call to fancybox() simple attaches the plugin to the selected element. Calling fancybox on a click event won't open anything.
I think you just need to add
$(li_element_that_you_create).fancybox();
to the code that creates the new LI elements in your list
EDIT
If you're using load, then you would do something like:
$('#ul_id_goes_here').load('source/of/news.feed', function() {
$('.quickview').fancybox();
});
