Here is the code for Javascript

<div id="div1" class="divclass">sandip</div>

<script type="text/javascript">
    var obj = document.getElementsByClassName("divclass");
    alert(obj[0].id);
</script>

Code in jquery

<div id="div1" class="divclass">sandip</div>

<script type="text/javascript">
    alert($('.divclass').attr("id"));
</script>

cheers

Why don't you access the div with id? If you have returned the object, what is the requirement to get the id?

In the e.g above,
var obj = document.getElementsByClassName("divclass");
Here obj is the collection of object (all objects that is linked with class class.
So, you need to iretae the object collection and see, which div you want.
But you need something to identify the unique div.
