js function to jquery

Question

i have a function like this in js

function rmStyle(parent){
    var rmStyle=document.getElementById(parent).getElementsByTagName("a");
    for (i=0;i<rmStyle.length;i++){rmStyle[i].className="";}}

i'd like to shorten the function, since i'm using jQuery... so, what should i write in jQuery?

jQuery is a JS framework - you can just use that function. Oh, and for future reference...indent! Readable code is happy code. — Andrew

@patrick dw - Yeah, I misinterpreted his question. I was thinking of it as "How do I do this in jQuery?", instead of "How can I make this shorter with jQuery?". — Andrew

$('#' + parent).find('a').removeClass();

The .removeClass() method will remove all classes on a selected item if no class name is passed.

I did not know removeClass could be called with no args. Very nice. +1

function rmStyle(parent) {
    $('#' + parent).find('a').attr('class','');
}

This will get the element with the parent id, find all a descendants, and set their class attribute to ''.

Or $('#'+parent+' a').attr(...);

@Phrogz: Yeah, I debated over that, but decided against it for clarity. Glad you mentioned it though.
