Using variables when referring to form elements using JS
Posted: Tue Apr 08, 2008 10:16 am
Hey guys.
I'm using javascript to loop through all the input textboxes of a form and sent them to nothing. I need to have a loop variable called $i in the name of the input element, however I can't find a way to do that (syntax errors, etc), so I am using the ID of the element - which is ok, but out of curiosity I wonder if it's possible.
Thanks!

Code: Select all
for ($i = 0; $i < 16; $i++) {
// This doesn't work, because I can't find a way to insert $i into the LHS.
// document.program.addr_+$i.value = '';
// This works fine
document.getElementById("addr_"+$i).value = '';
}
Thanks!
