loop through form elements wiith an id

[nikko50]

Hi all.

I have a form named "theForm". How can I loop through this form elements that have an "id" ATTRIBUTE to them and then populate my ids array?


var ids = new Array;

for(i=0; i<document.theForm.elements.length; i++)
{

IF ELEMENT HAS AN ID ATTRIBUTE POPULATE ids array

}

var ids = [ ];

var form = document.theForm;

for( i=0; i  < form.elements.length; i++ )
{
    var elem = form.elements[i];
    if ( elem.id != null && elem.id != "" )
    {
        ids.push( elem.id );
    }
}
