Why does Disabled = ture for html work?

Question

I noticed in our code that there is a disabled = ture' i the source code for anchor tag. I was wondering why it works in IE. I also searched the internet and it is also being used in a lot of source code via a search in the net. I have been searching if ture, a wrong spelling of true can also be used by IE.

Does anybody have any idea about this?

Answer 1

It used to be that to disable an element, you just did <input type="text" disabled>, so most browsers don't really care what goes in that attribute. I believe making it disabled="disabled" became a standard solely so that the code would be valid XML.

Answer 2

IE only checks for the existence of the disabled property. It's value doesn't matter.
