I've got a prompt in my java script, and I would like clicking "cancel" (which returns "null") to close the entire script. I'm thinking that the variable could be tested for the null value with an "if" statement imediately folowing the prompt and the associated action could either terminate the script or "goto" the end....maybe screwy, but looking for SOMETHING!
CODE
var rwdia = prompt("Enter rear wheel diameter-ex. 27","inches");
if (rwdia="") .......

You can do that yes. I would not use goto. Many programmers hate the goto statement since it very easily will make your code very unreadable. Try the null statement.

Ok, I don't really mind the goto (here the code is too short to get too confused) but how would I use the "null statement" here?

Put your code in a function. Then you can return when finished:
CODE

function doSexyThing()
{
    var rwdia = prompt("Enter rear wheel diameter-ex. 27","inches");
    if (rwdia="")
    {
        return;
    }

    alert("this thing is very sexy");
}

// call it
doSexyThing();
