Code:
<html>
<script language="javascript">
function ChangeColor(){
var z=document.forms.frmDemo
for (var i=0;i<z.elements.length;i++){
z.elements[i].style.backgroundColor = "#00FF00"
}
}
</script>
<script language="vbscript">
Sub btn1_OnClick()
Dim fld
For Each fld in document.forms.frmDemo.elements
fld.style.backgroundcolor = "#FF0000"
Next
End Sub
</script>
<body>
<form id=frmDemo>
<input type=text id=txt1><br>
<input type=text id=txt2><br>
<input type=text id=txt3><br>
<input type=text id=txt4><br>
<input type=text id=txt5><br>
<input type=button id=btn1 value="Click me">
<input type=button id=btn2 value="Click me too" onClick="ChangeColor();">
</form>
</body>
</html>Hope it helps,

yeah, that works good, but I need to iterate through the form objects to select just one of them. i.e. I have a form that has text boxes generated dynamically. So one time I might have three text boxes, one time I might have fifty. I can generate them with the numbers attached to their name. i.e. text1, text2, etc. But what I want to be able to do is when a user clicks on one of the text boxes, have the the textbox background color change.
If they were statically created, this would not be a problem, but since they are dynamically created, this causes a problem.
Hope this made sense. Tazzmann
