My problem

I'm trying to put a map on a webpage, the data being fetch with Ajax. It works fine with all browsers, but not IE9.

I get an error:

SCRIPT5007: Unable to get value of the property 'ajax': object is null or undefined

and the map does not load.

The code

       var mapModel = new Map(); 

       mapModel.get("leads").fetch({success: function(){ //error on this line
              var mapView = new MapView({ model: mapModel });
              $('body').append(mapView.el);
              mapView.render();
           }});

What I tried

This seems to be a very mon issue, here is the most up-voted question on the subject. So I tried to put

 <meta http-equiv="X-UA-Compatible" content="IE=8"/>

but it didn't solve anything.

My question

What I should I do to fix this problem?

• 1 Did you include the JQuery? Backbone's fetch() method is delegated to the $.ajax() method. if ajax can't be found on some object, it must be $ is missing. – Hetfield Joe Commented May 29, 2013 at 8:53
• I wondered about that too. But why does it work in chrome then? – L. Sanna Commented May 29, 2013 at 8:56
• On IE9 hit F12 and go to the console, type "$". result is? – Hetfield Joe Commented May 29, 2013 at 9:03
• so JQuery is not loaded, try to clear the cache of IE, and check out the configuration about javascript. – Hetfield Joe Commented May 29, 2013 at 9:20
• is it work on other browsers? if it works I don't know what's your problem, else it doesn't work then you need to change inside fetch, because it returned something (like json) – Ulug'bek Commented May 29, 2013 at 12:09

OK, I found the problem:

IE9 was rendering the page in patibility mode.

I added

<meta http-equiv="X-UA-Compatible" content="IE=edge" >

as the very first line of the header, and now it works.

Finally I solved this issue.

In my master page, there was a script manager. I replaced it with ToolkitScriptManager which is actually packaged with AjaxControlToolkit 4.0.

Now it works superbly.

Hope this might help someone
