Javascript Error: n is null in swfobject.js

My Web application r开发者_JS百科enders me "n is null" Javascript error in firefox browser when i try to access a particular page. This error originates in swfobject.js file.

Also i get another Javascript error "a is null" in firefox browser when i try to access a particular page.This error originates in MicrosoftAjax.js file.

Any help would be deeply appreciated.

Thanks.

Your problem may be that the code is trying to access an HTML element that has not loaded yet. To resolve this try wrap the code that is getting the errors in a jquery ready block if you are using jQuery:

$(document).ready(function () { 
//Code that uses SWF/MicrosoftAjax here
});

or if you are not using jQuery:

window.onload=function() // fixed windows to window
{
  //Code that uses SWF/MicrosoftAjax here
}

Use firebug to pinpoint the problem.

99%, the problem's origin is not swfobject.js but in some script that's loaded before it.
