[removed] style.display:'block' doesn't work

Question

any idea why this JavaScript just shows \"block\" and not the content of the (hidden) DIV?

Answer 1

This code describes your problem: http://jsbin.com/jigiy/1

TEST
Show my DIV

Why is this happening:

Javascript setters return the value input, so document.getElementById('mydiv').style.display='block' will return 'block', which is equal to href="javascript:'block'". Now it refers to about:blank and sets its content to block.

I'm not sure why the browsers refer and set the content of about:blank, but i think this has something to do with data-urls.
