I've just put a facebook like button on my rails app by adding the following tag into an html.erb page:
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js#appId=1419...&xfbml=1"></script><fb:like href="" send="" width="100" show_faces="" font="" layout="button_count" action="recommend"></fb:like>
And ... that works OK but I get a big white space on the page as the facebook sdk is loading. So, I thought I'd try putting this in my application.js file and running the function after the page is loaded. The only problem is that I can't get this to work at all :)
So far, I've kept the "fb-root" div in the html and I've placed the following function into application.js
$(function() {
$('#fb-root').after('<script src="http://connect.facebook.net/en_US/all.js#appId=1419...&xfbml=1"></script><fb:like href="" send="" width="100" show_faces="" font="" layout="button_count" action="recommend"></fb:like>');
});
However, this is not working for me and I can't figure out why (I'm a js newb). Any help would be greatly appreciated. Thanks!
You should load the javascript function asynchronously:
<script>
window.fbAsyncInit = function() {
FB.init({appId: 'your app id', status: true, cookie: true, xfbml: true});
};
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
</script>
Then once the javascript library has loaded, it will convert your fbml like button into the appropriate html iframe code. If it is showing a white space until it loads, put the like button fbml code inside a div and style that div with css.
Here is a full example which doesn't have the issue you are talking about (I load the javascript library asynchronously, on a timed delay to simulate a slow load. Notice that there is no white while the load button is loading.
<!DOCTYPE html>
<html>
<body bgcolor="#000">
<div id="fb-root"></div>
<fb:like href="http://stackoverflow.com" send="" width="100" layout="button_count" action="recommend"></fb:like>
<script>
window.fbAsyncInit = function() {
FB.init({appId: 'your app id', status: true, cookie: true, xfbml: true});
};
(function() {
// delay to simulate slow loading of Facebook library - remove this setTimeout!!
var t = setTimeout(function() {
alert('loading fb');
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}, 3000);
}());
</script>
</body>
</html>
OK, I figured this out. First, I put the following tags in the html:
home.html.erb
<div id="fb-root"></div><div id="facebook">[Facebook]</div>
The important tag here is "fb-root" as that is what Facebook's javascript will look for. Then, in my js file I add this function:
application.js
// facebook recommend button
$(function() {
likebutton =
'<fb:like href="" send="" width="100" show_faces="" ' +
'font="" layout="button_count" action="recommend">' +
'</fb:like>';
$.getScript('http://connect.facebook.net/en_US/all.js', function() {
FB.init({appId: 141936272547391,
status: true,
cookie: true,
xfbml: true
});
$('#facebook').replaceWith(likebutton);
});
});
And, no more white box, if he client doesn't have JS enabled they just see "[Facebook]" and my code is nice and maintainable. :)

I have a mobile layout page that loads a js file and it works fine.
#RenderBody()
<script>
$(document).ready(function () {
var moonth = $("#getcurrmonth").val();
var yeear = $("#getcurryear").val();
$("#hiddenyearval").val(yeear);
$("#hiddenmonthval").val(parseInt(moonth) - 1);
$("#caltab").collapsible("expand");
LOCAL.LoadMore();
LOCAL.LoadMore();
LOCAL.LoadMore();
$("#caltab").collapsible("collapse");
});
</script>
<script>
LOCAL = {
LoadMore: function () {...}
}
</script>
#Html.Partial("~/Views/Shared/_Tabs.mobile.cshtml")
But when I change to a page that uses the same layout the script never fires.
I have tried $(document).on('pagebeforeshow', '[data-role="page"]', function{..} as well as other suggestions I have found on here but no luck.
Thanks for your time.
I am relatively new to Jquery and Jquery mobile, I was just trying and tutorial to add Loading animation on the page, I was simply following the code provided in one of the demos. However I am getting the following error.
Uncaught TypeError: Object [object Object] has no method 'jqmData'
I am using the following code snippet and javascript
<button class="show-page-loading-msg ui-btn-right" data-icon="refresh" data-theme="d" data-textonly="false" data-textvisible="true" data-msgtext="Loading..." data-inline="true">Refresh</button>
<script>
window.$ = window.jQuery = WLJQ;
$( document ).on( "click", ".show-page-loading-msg", function() {
var $this = $( this ),
theme = $this.jqmData( "theme" ) || $.mobile.loader.prototype.options.theme,
msgText = $this.jqmData( "msgtext" ) || $.mobile.loader.prototype.options.text,
textVisible = $this.jqmData( "textvisible" ) || $.mobile.loader.prototype.options.textVisible,
textonly = !!$this.jqmData( "textonly" );
html = $this.jqmData( "html" ) || "";
$.mobile.loading( "show", {
text: msgText,
textVisible: textVisible,
theme: theme,
textonly: textonly,
html: html
});
setTimeout(WL.Client.reloadApp, 5000);
$.mobile.loading( "hide" );
});
</script>
The error is pointing to this line in the javascript theme = $this.jqmData( "theme" )
when i debugged on browser console i was able to see the button data values assigned to the $this variable
Please advice,
if you run the following:
console.log($.mobile.version);
... and check the console. Does it print out the version? Or does it say it is undefined?
If it is undefined, check if you have correctly referenced jQuery and jQuery mobile libraries, something like this:
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css">
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
Try to put your script into the 'mobileinit' event handler (or a page event handler), like:
<script src="js/jquery-2.0.3.js"></script>
<script>
window.$ = window.jQuery = WLJQ;
$(document).on('mobileinit', function() {
// your script
});
</script>
<script src="jqueryMobile/jquery.mobile-1.3.1.js"></script>
NOTE the sequence of the script
I am working on a web application and was making great progress using JQuery UI Tabs, specifically the 'url' method of dynamically updating the target url of the ajax request which was bound to each tab. I have created a simplified example here:
Each of the 2 Tabs, function 1 & function 2, display the results of some tests based on the parameters that are passed to the test. The tests remain the same throughout, but I was changing the variables used in the functions by manipulating the url bound to the tab. The 'url' method of updating the url being called on a lazy loading Tab allowed me to do this, but its now been deprecated and won't be supported at all soon. So I have been searching for a way to do this using the 'beforeLoad' event in JQuery UI 1.9.
The suggestion was that one could manipulate the ui.ajaxSettings to set the data parameter but there is a bug (http://bugs.jqueryui.com/ticket/8673), and it appears this won't be fixed. The workaround suggested is to manipulate the ui.ajaxSettings.url instead.
My working example is below, but I'm not sure if this is the cleanest / most appropriate way to achieve what I'm after and any suggestions would be most welcome. I struggled to find examples on how to do even this much, so hopefully it will help someone else in a similar situation.
<title> Jquery Tabs AJAX Test</title>
<script type="text/javascript" src="js/jquery-1.8.2.js"></script>
<script type="text/javascript" src="js/jquery-ui-1.9.1.custom.js"></script>
<link rel="stylesheet" type="text/css" href="css/smoothness/jquery-ui-1.9.1.custom.css">

<script type=text/javascript>
$(document).ready(function() {
$( '#tabs' ).tabs({ });
$('button.set_variable').click(function() {
var variable = $(this).val();
$( '#tabs' ).tabs({
beforeLoad: function( event, ui ) {
ui.ajaxSettings.url += "&variable=" + variable ;
}
});
var selected_tab = $('#tabs').tabs('option', 'selected');
$( '#tabs' ).tabs("load", selected_tab);
});
})
</script>
<button class="set_variable" value="1">Variable = 1</button>
<button class="set_variable" value="2">Variable = 2</button>
<button class="set_variable" value="3">Variable = 3</button>
<div id="tabs" >
<ul>
<li>Function 1 </li>
<li>Function 2 </li>
</ul>
</div>
</body></html>
N.B. The ajax.php file here just echos back what was passed to it.
<?php
extract($_GET);
var_dump($_GET);
?>
You could do something like this too :
var variable = '';
$( '#tabs' ).tabs({ beforeLoad: function( event, ui ) {
if(variable != '')
ui.ajaxSettings.url += "&variable=" + variable ;
}});
$('button.set_variable').click(function() {
variable = $(this).val();
});

I'm trying to use jQuery UI's .tabs() to obtain content via AJAX, but the default behavior is to grab the entire page's content. How would I obtain content from a specific #id and/or multiple #id's?
I have a feeling I will need to use the load: event (http://docs.jquery.com/UI/Tabs#event-load), but I need an assist figuring this out.
Example:
The Page with the tabs that is getting and displaying the tabbed content. I have placed #content after the first #the_tabs link to retrieve in an attempt to obtain that specific region of the content, but the entire page is still loaded.
<div id="tabs">
<div id="tabs_display">
</div>
<ul id="the_tabs">
<li><span>1</span></li>
<li><span>2</span></li>
<li><span>3</span></li>
<li><span>4</span></li>
</ul>
</div><!-- /#tabs -->
The page being retrieved by the previous markup:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Remote HTML Page Example</title>
</head>
<body>
<div id="content">
I want this content
</div>
<div id="other_stuff">
Not this content
</div>
</body>
</html>
the JS (for setup purposes):
$(document).ready(function(){
/* Tabs
--------------------*/
$(function() {
var $tabs = $('#tabs').tabs({
});
});
});
In Jquery-UI 1.9, "ajaxOptions" is depreciated; so instead the code below worked for me:
(ref: http://jqueryui.com/upgrade-guide/1.9/#deprecated-ajaxoptions-and-cache-options-added-beforeload-event)
$(function() {
$( "#the_tabs" ).tabs({
beforeLoad: function( event, ui ) {
ui.ajaxSettings.dataType = 'html';
ui.ajaxSettings.dataFilter = function(data) {
return $(data).filter("#content").html();
};
}
});
});
$(document).ready(function(){
/* Tabs
--------------------*/
var $tabs = $('#the_tabs').tabs({
ajaxOptions: {
dataFilter: function(data, type){
return $(data).filter("#content").html();
}
}
});
});
Solution props to Supavisah in #jquery on irc.freenode.net
I have had luck using .find, rather than .filter. Like this:
$(document).ready(function(){
$('#the_tabs').tabs({
ajaxOptions: {
cache : true,
dataFilter: function(data){
return $(data).find('#content');
},
}
});
});
I can't get any icons to be shown on a modal dialog box when I try to use jQueryUI via Google Ajax API. The icons do not appear but when I click on the locations where they are supposed to be the relevant functinality works (e.g. I can resize and close the modal dialog box). Here's the problematic screenshot and my code for Jetpack:
http://www.flickr.com/photos/64416865#N00/4303522684/
function testJQ() {
var doc = jetpack.tabs.focused.contentDocument;
var win = jetpack.tabs.focused.contentWindow;
$.get("http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js", function(js) {
var script = doc.createElement("script");
script.innerHTML = js;
doc.getElementsByTagName('HEAD')[0].appendChild(script);
$.get("http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.min.js", function(js) {
var script = doc.createElement("script");
script.innerHTML = js;
doc.getElementsByTagName('HEAD')[0].appendChild(script);
$.get("http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/ui-lightness/jquery-ui.css", function(js) {
var style = doc.createElement("style");
style.innerHTML = js;
doc.getElementsByTagName('HEAD')[0].appendChild(style);
script = doc.createElement("script");
script.innerHTML = 'var myDialogFunc = function () {';
script.innerHTML += '$("<div id=dialog title=\\"Basic Dialog\\"> <p>The dialog window can be moved, resized and closed with the X icon.</p></div>").appendTo("body");';
script.innerHTML += '$("#dialog").dialog({'
script.innerHTML += ' bgiframe: true, height: 140, modal: true';
script.innerHTML += ' });';
script.innerHTML += '};';
doc.body.appendChild(script);
win.wrappedJSObject['myDialogFunc']();
});
});
});
}
On the other hand, in a simple html document I can use Google Ajax API, load jquery and jQueryUI and get the icons correct without any problems. Here's the screenshot and source code that works as I expect:
http://www.flickr.com/photos/64416865#N00/4303522672/
<html>
<head>
<script src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
var myDialogFunc = function () {
$("#dialog").dialog({
bgiframe: true,
height: 140,
modal: true
});
};
// Load jQuery
google.load("jquery", "1.4.0");
google.load("jqueryui", "1.7.2");
google.setOnLoadCallback(function() {
myDialogFunc();
});
</script>
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/ui-lightness/jquery-ui.css" type="text/css" media="all" />
</head>
<body>
<div id="dialog" title="Basic Dialog">
<p>The dialog window can be moved, resized and closed with the X icon.</p>
</div>
</body>
Any ideas about why I can't get the icons in my Jetpack version?
Code below solves my problem:
js = js.replace("url(", "url(http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/ui-lightness/", "g");
style.innerHTML = js;
