How do I scan for a checkbox's name...

[ggallen]

I have a dynamically created HTML page which will have
any number of checkboxes (all will start with "VJCDE-")

How do I scan all the elements on the form to see if
the name starts with VJCDE-

I realize I'm using elements[]
but how do I get the name of the element?

Here are two methods. One using name and the other indexOf:

<form>
<input type="checkbox" name="VJCDE-">
</form>


<script>
var inputs = document.forms[0].getElementsByTagName('INPUT');			
for(i=0; i<inputs.length;i++){
if(inputs[i].getAttribute('TYPE')=='checkbox' && inputs[i].name == 'VJCDE-' ){
alert('Ha-Ha You have been found! (1)')
}

if(inputs[i].getAttribute('TYPE')=='checkbox' && inputs[i].name.indexOf('VJCDE-') > -1 ){
alert('Ha-Ha You have been found! (2)')
}
}

</script>

My method was:

'function checkall() {'
' var elen = document.FORM1.elements.length;'
' for (var i=0 ; i<elen ; i++) {'
' var ename = document.FORM1.elements[i].name;'
' if (ename.substring(0,6) == "VJCDE-") {'
..............
' }'
' }'
' return;'
'}'

ignore the surrounding 's

Any reasons why not to do it this way? aside from personal choice.

Thanks

aside from changing:

' var ename = document.FORM1.elements[i].name;'
' if (ename.substring(0,6) == "VJCDE-") {'

to

if (document.FORM1.elements[i].name.substring(0,6) == "VJCDE-")


Since I was testing. it was easier to break things up into
pieces, to see what worked and what didn't.

Whichever way you prefer and works for you sounds like a winner to me.
