change background color of current element

Question

how can I change the background color of current element using plain javascript? for instance

<li onmouseover="this.backgroundColor:#000;">something</li>

This doesn't work, but you will get the idea what I want to do. Thank you

Answer 1

快好了。

<li onmouseover="this.style.backgroundColor='#000';">something</li>

Answer 2

this.style.backgroundColor= 'black';

或者，如果可以的话，最好使用简单的CSS：

li:hover { background-color: black; }

Answer 3

CSS hover would probably be the most elegant solution, there is an IE6 fix for this: csshover.htc

But if it were me I would use jQuery, and it would provide you excellent cross-browser support.
