If propmt = example, redo prompt?

[Dan Ebberts]

Hard to say exactly what fits your situation, but maybe something like this:


// initialization
var oldName = "whatever";

// prompt user for new name
var newName = oldName;
var myPrompt = "Enter new name.";
while (newName == oldName){
newName = prompt(myPrompt,"");
if (newName == null) break;
myPrompt = "Name already in use. Enter new name."
}

if (newName == null){
alert("User canceled.");
}else{
oldName = newName; // ready for next time
alert(newName);
}
