Question

Recently I ran into a mysterious problem that IE (6-8) is keeping throwing me an error. I don’t know if this is the problem, but I think it is.

Open up the F12 developer tools in a jQuery included website, enter

$(window).load(function(){
     alert("Wont able to see me");
});

And an error will popup:

“Unable to get value of the property ‘slice’: object is null or undefined”

Did I do anything wrong, or anything else???

Answer 1

The latest jQuery (1.7.1) with IE10 and IE9 does not produce such an error for me.

As a side note; If you wish to execute something when the dom is ready;
Try this way;

$(function(){
     alert("Wont able to see me");
});

I believe this is the standard convention for attaching a function to domready event.
