Using array in javascript?

The jsp page is not recognizing my array aa[] in the line document.dd.aa[i].value.... to be specific dd is my form name....

<script type="text/javascript">
function chk()
{
    var errmsg = new String("");
    var aa = new Array("t1","t2");
    for(var i=0;i<=1;i++)
        {
           var ddd = document.dd.aa[i].value;
           if(ddd=="")
               {
                  errmsg += "Empty field:" +"\n";
               }
        }
        alert(errmsg);
}
</script>

Thx in advance :DD...

var aa = new Array("t1","t2");

Above is not part of the form. So var ddd = document.dd.aa[i].value; is wrong.

You can directly access aa array. So do like this.

var ddd = aa[i];

To access the array, it's simply:

var ddd = aa[i];

Also, it's better to create the array using literals:

var aa = ['t1','t2'];

If dd is a form, then document.dd returns the DOM form element named dd. To access the elements, you need to traverse the element using DOM traversal methods, like getElementById, getElementsByTagName and so on.
