Question

I have a class as

 <div class="group-left article_left">

I need to add a id for this class dynamically using JavaScript.

i have added the following code

    var thediv = document.getElementByClass("#group-left");
     thediv.id = "pad_id";

But the id is not appearing in my code.Can anyone help me.

Answer 1

There is now getElementsByClass method in javascript unless you use some library. You can use jquery

$('.class').attr('id','pad_id');

You should only use one id per element though. Remember that
