Following is my javascript program. I am trying to get all child tags of parent div tag but when I am running the program document.getElementById('abc') returning null.

function init(){
//               currentDiv = document.getElementById("intro");
                alert("working");
                count = 0;
                divs = document.getElementById('abc').getElementsByTagName("div");

                alert("HI " + divs)
                currentDiv = divs[count];
                nextDiv = divs[count + 1]
                count = count + 1;
            }

window.onload = init();

Following is my div tag definitions:

<div id='abc'> 
<div></div>
</div>

thanks.

The problem is in this line:

window.onload = init();

You are running init and setting the return value as the value of window.onload. My guess is that the code is being executed before the DOM is ready, i.e. before the divs exist.

Try this instead:

window.onload = init;

I suggest you start using jQuery instead, then you have much more powerful tools for this kind of DOM search/traversing

<body onload="init()">
    <div id='abc'> 
        <div></div>
    </div>
</body>

this probably solves your problem
