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;

I'm using jQuery Mobile 1.3, and attempted to follow a tutorial in order to create my own custom widget.
I'm getting stuck on the very first step, and I'm not sure if I'm following the right example for the right version of jQuery mobile.
There is no error on the page, my element is just never enriched.
(function($) {
$.widget("mobile.target", $.mobile.button, {
/** Available options for the widget are specified here, along with default values. */
options: {
inline: false,
mode: "default",
height: 200
},
/** Mandatory method - automatically called by jQuery Mobile to initialise the widget. */
_create: function() {
var inputElement = this.element;
var opts = $.extend(this.options, inputElement.data("options"));
$(document).trigger("targetcreate");
inputElement.after("<button>" + inputElement.val() + "</button>");
},
/** Custom method to handle updates. */
_update: function() {
var inputElement = this.element;
var opts = $.extend(this.options, inputElement.data("options"));
$(document).trigger("targetupdate");
inputElement.siblings("button").text(inputElement.val());
},
/* Externally callable method to force a refresh of the widget. */
refresh: function() {
return this._update();
}
});
/* Handler which initialises all widget instances during page creation. */
$(document).bind("pagecreate", function(e) {
$(document).trigger("targetbeforecreate");
return $(":jqmData(role='target')", e.target).target();

Expected output was a custom JQueryMobile button that inherits from the JQueryMobile button. Not just a tiny html5 button in a div. e.g. Div1 rendering the same as Div2 but with customized changes made.
You are trying to get an input element in jQuery code. But you defined a div element in the HTML page.
That is the problem. Change it to input.
Check the below code
The tutorial you followed states that only use the :jqmData if you didn't use the HTML5 data attribute. Remove it
(function($) {
$.widget("mobile.target", $.mobile.widget, {
options: {
inline: false,
mode: "default",
height: 200
},
_create: function() {
var inputElement = this.element;
var opts = $.extend(this.options, inputElement.data("options"));
$(document).trigger("targetcreate");
inputElement.after("<button>"+inputElement.val()+"</button>");
},
_update: function() {
var inputElement = this.element;
var opts = $.extend(this.options, inputElement.data("options"));
$(document).trigger("targetupdate");
inputElement.siblings("button").text(inputElement.val());
},
refresh: function() {
return this._update();
}
});
$(document).bind("pagecreate", function(e) {
$(document).trigger("mywidgetbeforecreate");
return $("[role='target']", e.target).target();

I am trying to make div element screenshot, but combined with draggable jQuery, and have no luck, I can take screenshot of div and save it like png, but if I drag some elements on that div and then save screenshot I get only what is inside that div and draggable elements over that div? Any idea, this mine code so far
<script type="text/javascript" src="js/html2canvas.js"></script>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<script language="javascript">
$(document).ready(function() {
$("#myBtn").click(function () {
html2canvas($("#chartDiv"), {
onrendered: function (canvas) {
var imgSrc = canvas.toDataURL();
$("#myDiv").html('').show();
var url = "ajax.php";
$.post(url, {contentVar: imgSrc} ,function(data) {
$("#myDiv").html(data).show();
});
}
});
});
});
</script>
<script>
$(function() {
$( ".draggable" ).draggable();
});
</script>
I am using AJAX to save image and present in new element
AJAX.PHP
$contentVar = $_POST['contentVar'];
$filteredData=substr($_POST['contentVar'], strpos($_POST['contentVar'], ",")+1);
//Decode the string
$unencodedData=base64_decode($filteredData);
//Save the image
file_put_contents('img.png', $unencodedData);
echo "<img src="img.png">";
And here is the HTML:
<div id="chartDiv"><img src="img/assets/logo.png"></div>
<button id="myBtn">Create image</button>
<div id="myDiv"></div>
<img src="img/assets/logo.png" class="draggable" />
<img src="img/assets/logo.png" class="draggable" />
Why not disable the the draggalbe elements before taking the screenshot, then re-enabling them. This will remove the jquery_ui draggable elements and css.
While their are plenty of posts regarding reloading a jQueryUI tab via the load method, I can't seem to make it work in 1.9+. I wish I could see a way to show this in a fiddle, but as I don't... note that the refresh button/function works every time in the following nested tabs set-up under 1.8+ but works only once under 1.9+, and fails after that. In context, (loading dynamic content via php under wordpress) it doesn't work at all. According to the ajaxStart()ajaxStop() function calls, an ajax call is made every time the refresh button is clicked, however the content (watch the date/time under tab E or tab A/sub parent E) is only reloaded on the first click of the #refresh button, which fails to re-load the tab content on subsequent clicks.
stye.css
div.clear { clear:both; }
#refresh { position: relative; top:-40px; left:300px; }
#loading
{ display:none;
position: absolute;
top:100px;
left:300px;
font-size: 200%;
z-index:1001;
border:3px solid green;
background:#ffffff;
}
tabs.js
jQuery(function()
{ set_tabs();
jQuery('body').on("click", "#refresh", function()
{ jQuery('.tabset ul li a').each(function()
{ var link = jQuery(this);
var tab = link.parent();
var tabset = link.closest('div.tabset');
if(tabset.is(':visible') && tab.hasClass('ui-state-active')) index = link.text().replace(/ /g, '_');
});
jQuery(".tabset").tabs( "load" , index );
});
jQuery("#loading").ajaxStart(function() {jQuery(this).show();});
jQuery("#loading").ajaxStop(function(){ jQuery(this).fadeOut(1500); });
});
function set_tabs()
{ jQuery('.tabset').tabs({ cache:true }); }

The .live() function has been deprecated for a while now, and support is completely gone in jQuery 1.9+. Use this:
$(document).on("click", "#refresh", function() {
// your current "live" code
});
So it turns out that not only has the cache option been deprecated in 1.9+ it's legacy behavior has been altered such that (if used) the load method will not reload the tab content.
The approach I've come up with is -- I think -- an abomination which I'm hoping some one might provide a cleaner alternative to. (oh pleeeaazzz!) Anyway, FWIW... here's what I came up with.
tabs.js (revisited)
jQuery(function()
{ set_tabs();
jQuery(document).on("click", "#refresh", function()
{ refresh = {};
refresh.tab = true;
jQuery('.tabset ul li a').each(function()
{ var link = jQuery(this);
var tab = link.parent();
var tabset = link.closest('div.tabset');
if(tabset.is(':visible') && tab.hasClass('ui-state-active')) index = link.text().replace(/ /g, '_');
});
jQuery(".tabset").tabs( "load" , index );
});
jQuery("#loading").ajaxStart(function() {jQuery(this).show();});
jQuery("#loading").ajaxStop(function(){ jQuery(this).fadeOut(1500); });
});
function set_tabs()
{ jQuery('.tabset').tabs(
{ beforeLoad: function( event, ui)
{ if(typeof refresh.tab =='undefined')
{ if ( ui.tab.data( "loaded" ))
{ event.preventDefault();
return;
}
ui.jqXHR.success(function() { ui.tab.data( "loaded", true );});
} else refresh={};
}
});
}
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'm building a site which allows users to create an html page which can then be saved and shared on another site. I want them to be able to resize and drag the page elements. I can do this using jQuery, but I'm not sure how I then save that so that when the page is viewed elsewhere, it looks the same.
I haven't decided yet how to store the page info, but what I'm thinking is that I can store each element in the database along with its absolute position, and its contents. Does that sound like a good plan?
If so, how do I get the position for the div to pass to the php so that it can be saved?
Thanks.
JQueryUI Resizable has an event called resize that you can use:
var resposition = '';
$('#divresize').resizable({
//options...
resize: function(event,ui){
resposition = ui.position;
}
});
The same occurs with JQueryUI Draggable and its event drag:
var dragposition = '';
$('#divdrag').draggable({
// other options...
drag: function(event,ui){
dragposition = ui.position;
}
});
resposition and dragposition is going to be arrays. You can see it working here: http://jsbin.com/uvuzi5
EDIT: using a form, you can save dragposition and resposition into hidden inputs
var inputres = '<input type="hidden" id="resposition" value="'+resposition.left+','+resposition.top+'"/>'
$('#myform').append(inputres);
var inputdrag = '<input type="hidden" id="dragposition" value="'+dragposition.left+','+dragposition.top+'"/>'
$('#myform').append(inputdrag);
And in your PHP file to handle the form:
$dragposition = $_GET['dragposition'];
$resposition = $_GET['resposition'];
$dragposition = explode(',',$dragposition);
$resposition = explode(',',$resposition);
Finally, both variables should be arrays with top and left attributes:
$dragposition => [top,left] attributes from draggable
$resposition => [top,left] attributes from resizable
you have to save position at some where so that you can get position
details when next time you open page.
option 1: you can store html elements position details in "localStorage" its default browser storage.
Example: Demo
<!DOCTYPE html>
<html lang="en">
<head>
<title>Dashboard</title>
<!-- jQuery -->
<script src="vendor/jquery/jquery.min.js"></script>
<link rel="stylesheet" type="text/css" href="dist/css/jquery-ui.min.css">
<script src="dist/js/jquery-ui.min.js"></script>
</head>
<body>
<script>
var positions = JSON.parse(localStorage.positions || "{}");
$(function() {
var d = $("[id=draggable]").attr("id", function(i) {
return "draggable_" + i
})
$.each(positions, function(id, pos) {
$("#" + id).css(pos)
})
d.draggable({
containment: "#wrapper",
scroll: false,
stop: function(event, ui) {
positions[this.id] = ui.position
localStorage.positions = JSON.stringify(positions)
}
});
});
</script>
<div id="wrapper">
<div id="draggable" class="ui-widget-content draggable" style="height:100px;width:100px;float:left">Div1</div>
<div id="draggable" class="ui-widget-content draggable" style="height:100px;width:100px;float:left">Div2</div>
<div id="draggable" class="ui-widget-content draggable" style="height:100px;width:100px;float:left">Div3</div>
</div>
</body>
</html>
option 2: you can store html elements position details in "your database"
