AJAX in jsFiddle

Question

How do you simulate jQuery $.get() to load data from a different domain in jsFiddle?

/* This won't work in jsFiddle. */    
$.get("http://www.google.com", function(data) { ... } );

As we know, there is limitation:

Due to browser security restrictions, most "Ajax" requests are subject to the same origin policy; the request can not successfully retrieve data from a different domain, subdomain, or protocol.

I solved this by creating a Fiddle in jsFiddle just for testing Ajax loads. It’s some very simple HTML with an image and some copy — you can see it here:

<div class="container">
    <img id="picture" src="http://media.smashingmagazine.com/uploads/2012/01/best-of-no-150px.png" />

It covers some key principles and applies these directly to something useful and relevant: the creation of a simple but functioning portfolio app for the iPhone.</p>
    <div style="clear: both;"></div>
</div>

body {
    font-family: Arial;
    color: #333333;
    line-height: 1.4em;
}

img {
    margin: 0 0 1em 1em;
    padding: 1em;
    background: #ffffff;
    border: 1px solid #eaeaea;
    display: inline-block;
    float: right;   
        -moz-border-radius: 8px;
        -webkit-border-radius: 8px;
        border-radius: 8px;

}

.container {
  background: #fafafa;  
  padding: 1em;        
}

Demo on JS Fiddle.

If you use Firebug to click on the “result” frame, you can get the source URL of the iframe. When you copy this source URL into the Fiddle containing your Ajax request, it will work because now it is on the same domain. Here’s a demonstration:

<div class="excontainer">
    <button id="loadbasic">basic load</button>
    <div id="result"></div>

</div>

body {
 font-family: Arial;   
}

.excontainer {
  padding: 1em;    
}

label {
 display: block;
 width: 100%;   
}

p {
 padding: .5em;   
}

a, a:visited {
 color: #2d9afd;   
}

.changed {
  color: #ff0099;   
}

.highlight {
  background: #faffda;   
}

.entered {
  color: #f5560a;
}

.green {
 color: #7fbf38;   
}

.hellomouse, .clickable, #foo, #event {
 cursor: pointer;   
}

button {
 margin-bottom: 1em;   
}

div {
  margin: 1em 0;   
}

#foo {
 display: inline-block;   
}



ul {
 margin: 1em 0;   
}

.form, form, .stuff, .morestuff, stuff3 {
    margin: 1em 0;
    padding: 1em;
    background: #ececec;
}

input {
 font-size: 1.1em;
 padding: 2px;    
}

.placeholder {
   color: #ff0099;  
   font-weight: normal; 
}

::-webkit-input-placeholder {
   color: #cccccc;
}

:-moz-placeholder {  
   color: #cccccc;  
}

:-ms-input-placeholder {
    color: #cccccc;
}

:focus::-webkit-input-placeholder {
    color:transparent;
}

.content {
    margin-top: 5px;
    padding: 1em;
    background: #eeeeee;     
}

// no need to specify document ready

$(function(){

    $.ajaxSetup ({

    var ajax_load = "<img src='http://automobiles.honda.com/images/current-offers/small-loading.gif' alt='loading...' />";

    $("#loadbasic").click(function(){
        $("#result").html(ajax_load).load(loadUrl);
    });

// end  
});
