Question

Grabbing Google Directions gadget from Ajax call

Answer 1

+1 A:

If I am understanding you correctly this is an unnecessary use of AJAX. From what it seems like you want to do is load JavaScript via a JavaScript call. This can be accomplished using either method described here. Example:

<script type="text/javascript">

function dhtmlLoadScript(url)
{
   var e = document.createElement("script");
   e.src = url;
   e.type="text/javascript";
   document.getElementsByTagName("head")[0].appendChild(e);
}

onload = function()
{
   dhtmlLoadScript("dhtml_way.js");
}

</script>

If the above link does not help or I am misunderstanding your question please provide further clarification or some sort of code example.

Following up on your comment

Here is a work around for your gadget, the below code would be on your main page (the one that is initially loaded). Here is my test HTML page:

<html>
<head>
  <script type="text/javascript">
  var gadget;

  function getGadgetAndMove(node)
  {
    gadget = document.getElementsByTagName("table")[0];
    node.appendChild(gadget); 
    gadget.style.visibility = "visible";
    gadget.style.display = "inline-block";
  }
  </script>
  <style>
  .ig_reset, .ig_tbl_line { visibility:hidden;}
  </style>
</head>

<body>
  <div onclick="getGadgetAndMove(this);">Test</div>
</body>
  <script src="http://www.gmodules.com/ig/ifr?url=http://hosting.gmodules.com/ig/gadgets/file/114281111391296844949/driving-directions.xml&amp;amp;up_fromLocation=&amp;amp;up_myLocations=1600%20Amphitheatre%20Pkway%2C%20Mountain%20View%2C%20CA&amp;amp;synd=open&amp;amp;w=320&amp;amp;h=55&amp;amp;title=Directions+by+Google+Maps&amp;amp;brand=light&amp;amp;lang=en&amp;amp;country=US&amp;amp;border=%23ffffff%7C3px%2C1px+solid+%23999999&amp;amp;output=js"&gt;&lt;/script&gt;
</html>

If you need further explanation please let me know.

While that does help (I've never been able to figure out how to add js src links dynamically), I'm not quite sure if that helps my particular problem. I'm using the AJAX to load separate pages (for certain design reasons) but one of the pages has the google directions gadget. From what I've read AJAX can't load cross site scripts, and that's where I think the problem is coming in. Does this solution work around that?
