Clearing specific form fields!

can I do this?

[dreamcatcher]

Hi,

Lets say I have a form and in that form are 10 input type text fields that would contain e-mail addresses and I want to have a button to clear those and nothing else? Like a reset button but only for specific fields.

Can I do this?

Thanks.

Yes. Not so hard, it all depends on what you are using to distinguish these textboxes from the other inputs.

1 Are there textboxes within the form that you don't want cleared?
2 Do these Tboxes have id's?

Thanks Bernard. I finally got it:

<script language="javascript">

function reset_emails()
{
for (var i=0; i<document.friendform.elements.length; i++)
{
if (document.friendform.elements[i].name.indexOf("friend_email")!= -1)
{
document.friendform.elements[i].value = "";
}
}
return true;
}
</script>

:)

Cool. I was asleep anyway!

It's probably worth mentioning that - just for the purposes of code clarity/efficiency - you could set a local variable at the top of the function,

var elements = document.friendform.elements

then simply use that instead throughout.

Also, if you are dealing with modern browsers only,

document.getElementsByName("friend_email")

will give you a collection of all of them.

Thanks for the insight Bernard. I have made a note of your comments for next time. :)
