JavaScript Prompt Box Cancel Button?

Question

I have a JavaScript function as follows:

function popup(username) {
var req = createAjaxObject();
var message = prompt(\"Message:\",\"\");
if(message != \"\"         


        

Answer 1

Yeah, my suggested comment does work

var message = prompt("Message:","");
if(message){
    alert("Not working!");
} else {
    alert("Working!");
}
