setAttribute does not work in IE

[expert_21]

I tried something like this:

document.getElementById("spanID").setAttribute("class", "testClass");

Works in Firefox, but does not work in IE (both 6 and 7). Anyone know of any workaround?

Use className instead of setAttribute().

document.getElementById("spanID").className = "testClass";

Thanks a lot Kravvitz, works perfect.

for class to be set with setAttribute in IE you have to use className:

elm.setAttribute('className', 'class');

the same is for "for" in lable elements

elm.setAttribute('htmlFor', 'for');

IE problem only
