Using Classes

[scriptkeeper]

Hey all, I know you can reference certain elements buy its ID many different ways! Is it possiblle to do the same with class names? I know I have seen javascript manipulating class names somewhere, .className or something? Thanxs 4 your time1

[glenngv]

document.getElementById("id").className

className is read/write property

[scriptkeeper]

So you have to already know the element you can not reference by class names?

You mean a generic way...

I am not quite sure, but you can use
document.getElementById[0].className

Or maybe this http://simon.incutio.com/archive/2003/03/25/#getElementsBySelector might help.

That's a lot of code .. if you just want elements by classname and you know what tag name they are, you can iterate like that:

var tags = document.getElementsByTagName('div');
var tagsLen = tags.length;
for(var i=0; i<tagsLen; i++)
{
if(tags[i].className == 'something')
{
alert("this one!");
}
}
