Answer 1

Your code appears to work fine in this fiddle, using jQuery 1.6

Answer 2

To retrieve the value of elements, use val(). Since divs don't have values, you should use data() to set and get data.

Answer 3

I can confirm this code snippet works perfectly in Chrome 11, Firefox 4 and IE 9 using the jQuery Git version.

EDIT: For the ones advising prop(), check the docs. Prop() is used for boolean attributes like: checked, disabled etc.

Answer 4

if using the latest jQuery, try with:

$.prop(propertyName);

Answer 5

Yes, since jQuery 1.6 I think you need to use .prop() instead of attr().
