if(obj!==null): why can't check the null value?

Recommended Posts

Please kindly go tohttp://lifelearning.xtreemhost.com/lib.htmlA testing page. Just check the checkbox "Lib1" and do not enter anything in the input boxI have checked if sFound1 is null in the if condition (already commented in the codes,but the table (at the bottom) still returns the null value. Can anyone help me a bit here?Many thanks in advance.
