Question

I have a label that is sometimes empty. How do I set up a conditional statement on the client side to test this?

i have

var label = document.getElementByID("<%=label1.ClientID %>").innerHTMl;

to get the text, but i can’t seem to figure out an if..else statment if it is empty or not. label.length == 0; label == null, etc don’t seem to work. any help?

Answer 1

try this:

if(label){
  // The label is defined
}

Neither the if nor an else on it may execute if its undefined, so best not to use an else on this (seems weird, but I just did a check with Firefox).
