title: Loading .js file cross domain using ajax
body: <p>I'm trying to access a cross domain .js file using ajax:</p>
  
  <pre><code>$.ajax({
      type:'get',
      crossDomain:true,
      url: "http://localhost/62588/scripts/bootStrapper.js",
      contentType: "application/json",
      dataType: 'jsonp'    
  }).done(callback);
  </code></pre>
  
  <p>I have a callback at the moment:</p>
  
  <pre><code>getBootStrapperScript(function (callback) {         
         //do somethibg
  })
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>XMLHttpRequest cannot load http://localhost/62588/scripts/bootStrapper.js. Origin http://localhost:62607 is not allowed by Access-Control-Allow-Origin.
  </code></pre>
  
  <p>I have been reading about JSONP but I'm not sure how to use it to load a .js file from anoather domain.</p>
  
  <p>If I change the above code to use 'jsonp' for the datatype but I then get this errer:</p>
  
  <pre><code>GET http://localhost/62588/scripts/bootStrapper.js?callback=jQuery18206067646441515535_1354459693160&amp;_=1354459696966 404 (Not Found) 
  </code></pre>
  
  <p>How can I load cross domain js files?</p>
