validate 3 fields
jr
required in a search form. Zonenm and zoneid are required together.
If someone searches on a bu and also a zoneid, then they must also
search on the zonenm and vice versa.So it is either all 3 or just the
bu. The bu validation always works. HOwever if I search on bu and
zoneid for example, I get a message asking for zonenm, but
alternatively, if I ask for the zoneid and bu, it should ask for the
zonenm. I tried it with the 3rd else if as an else instead of else if
but then I got a syntax error. thanks,
<script type="text/javascript">
function checkscript() {
var ele = document.forms[0].elements;
if (!ele.search_bu.value) {
alert('The Business Unit is a required field!');
return false;
} else if (ele.search_zoneid.value && !ele.search_zonenm.value) {
alert('Zone ID but no zone number');
return false;
} else if(ele.search_zonenm.value && !ele.search_zoneid.value) {
alert('Zone Number but no zone id');
return false;
}
return true;
}
</script>

Why use else's at all? Each conditional branch returns after all. ;)

aren't you too tired to always ask the same thing ?
can't you think by yourself ?
if ( bu.value ) {
if ( zoneid.value && !zonenum.value ) { blah 1 }
else
if ( !zoneid.value && zonenum.value ) { blah 2 }
}
else { blah 0 }
the "blah"s must return false

What was the error message, and what line in the script did it identify?

There wasn't an error message but the user could perform the search
incorrectly. It is an enforced business rule to search only on both.

I believe I this one does work. I was testing on the wrong page or
something else. It is not elegant but it works.

not so much ... not so much ... if / else are the same everywhere ;-)

Pretty much and you don't need an else if the previous conditional
clause exits the function. JSLint is good for spotting these issues.
SAM
Absolutely !

You are assuming that the poster is an intelligent being. It is
however JRough, to whom intelligence is a foreign land.

You are assuming I know one "JR" (or "jr") from the next. That's why
people should use unique "handles" on Usenet, preferably their real
name.
