Advice on Script

**Snoey** · 07-06-2011, 03:38 PM

New to javascript...I'm looking to see if:

1. Is there is a better way to do this? Is this a good way or is there something else I should be doing?

2. I have 8 different fields I have to pair up and check all in sequential order. Example, checking earnings_work1 to earnings_work_occur1, checking earnings_work2 to earnings_work_occur2, etc. Do I need to repeat the script below 8 times or where should I be heading?

Code:

<SCRIPT LANGUAGE="JavaScript">
function validateForm()
{


if (form1.earnings_work1.value.length != 0)
{
	if (form1.earnings_work_occur1.value.length == 0) {
		alert("You must enter an occurence.");
		return (false);
		}

} 
}
//  End -->
</script>

tbh I'd just use jQuery with the validation plugin/module.
