Hi all... just a quick question! I have a standard form field that gets filled from a database when the page loads... all good so far! What I would like to do is allow the users to increment this value by adding a plus and minus each side. I'm guessing this can be done with JavaScrips, but I don't know where to begin!

If anybody can point me in the right diection, or even to an online tutorial, i'd seriously appreciate it!

Thanks in advance

You will probably get more responses in the JavaScript forum [webmasterworld.com].

Hi!
Try with it.

<input type=button value='-' onclick='javascript:process(-1)'>
<input type=test size=10 id='v' name='v' value='0'>
<input type=button value='+' onclick='javascript:process(1)'>

<script language=javascript>
function process(v){
document.getElementById('v').value+=v;
}
</script>
