Re: [Flashcoders] AS3: if (urlvars.bids != null) trace(urlvars.bids); still prints null?

if you're sure you receive an empty value and the check does not work, 
maybe try

if (String(urlvars.bids) != "")

And you may have to check for "0" instead of 0, again a string.

if (urlvars.bids != "" && urlvars.bids != "0")

Hello,

does anybody please have an idea, why would this code:

private function handleComplete(event:Event):void {
var urlvars:URLVariables = event.target.data;
..
if (urlvars.bids != null && urlvars.bids != 0) {
trace(urlvars.bids);
   .
   }
}

still print out "null"? Is it maybe because null != null in AS3
and I have to perform some other check similar to isNaN()?

Thank you
Alex

No, null==null in AS3.

I suspect that your url variable bids contains the string "null", sent
from the server-side.

the "null" is maybe a string if it's from url variables.
