I am writing a code to add a div depending on a set of ‘object’ found in document on click of button.

When Document.getElementsByTagName(‘object’);
there is only one object, but it goes in to an infinite loop! giving me incremented value of swf.length incremented by one infinitely in an alert.
can you help whats wrong am i doing!

<script>
 function get2(){
    var swf = document.getElementsByTagName('object');
    for (j=0;j<swf.length ;j++ )
    {
        alert(swf.length);
        var objs = swf[j].getElementsByTagName('param');
        for(i=0;i<objs.length;i++){
            id = objs[i].getAttribute('name');
            if (id == 'src'){
                source = objs[i].getAttribute('value')
                dv = document.createElement('div');
                dv.setAttribute('id','myContent');
                dv.setAttribute('border','2');

               document.getElementsByTagName('body')[0].appendChild(dv);
               /* code to embed a new swf object in new Div*/

            }/*if*/
        }/*for*/
    }/*outer for*/
 }/*function*/

here is the HTML part:

<body>


<div id="old">
</br><h1> Hello </h1>

<object id="myId1" width="250" height="250" name="movie1" classid="clsid:d27cdb6e-ae6d-    11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0"><param name="src" value="whitebird.swf">
</object>
<h1> welcome to flash</h1>

</div>
</br>
<input type="button"  onclick="get2()" value="Insert"/>
</body>

    Put a breakpoint in your inner for loop and inspect the values of j, i, and getElementsByTagName(‘object’).length as well as swf[j].getElementsByTagName(‘param’).length after the first iteration and post the results. Try getting your length outside the loop (which is good practice anyway). Also use the var keyword in your loops:

    var objectLength = swf.length;
for (var j = 0; j < objectLength; j++)
{
     ...
}

    You aren’t adding more object tag in your div and just omitted that code are you?
