I am creating a new custom module. Exactly when I hover over a menu item an error appears in the IE7 Browser:

Line: 262

Char: 2

Error: 'style.display' is null or not an object

Code: 0

I'm using DNN 4.5.3 and don't know where to begin to track this down.

If it only appears in IE7 -- this may not be the ultimate solution. but -- you can still do some investigating with firebug in firefox to track down what exactly is happening there.....

what menu item is it that you are hovering over? -- a custom menu?

I don't know that it only appears in IE7, that's just what my Vista development system has. It errors out hovering over any menu item such as "Home".

This error doesn't happen on other pages I have setup so I'm guessing it must have something to do with my custom control.

And Line 262 doesn't tell me anything. If I view source and copy and paste the HTML into Visual Studio where I can get a line number count, it only goes to line 186.

The following is the DNN javasript where this is breaking. eSrc is passed in as a Boolean False. Now I just have to figure out what is causing this. There is no style.display property for a Boolean.

//dims object

dnn_dom_positioning.prototype.dims = function (eSrc) {

var bHidden = (eSrc.style.display == 'none');

I have some more information. When I remove references to javascript source in my custom control in my custom module, the error goes away. Somehow this javascript is interfering with the DNN javascript. Any easy way to prevent this interference? Any easy way to track down this interference?

 

<script src="<%=this.ModulePath %>scripts/myscript.js" type="text/javascript"></script>

<link rel="stylesheet" href="<%=this.ModulePath %>css/mycss.css" type="text/css" media="screen" />
