Question

I have such code

if(itemid){
   expandHighlight(itemid);
}


function expandHighlight(itemid){
    alert(itemid);
}

Sure, it works as it should, but if itemid has value of “0” (int) – nothing happening. A get no alert, just nothig… any ideas?

Answer 1

Either make your if more sensible:

if(itemid !== undefined)

Or remove it entirely
