Question

I’m running this little piece of Javascript:

if(path.length >= 7000){

    alert("OVER 7000");
}

In this script, path.length is a variable which begins at 0 and increments to 7000 (and beyond) – further details aren’t relevant.

What I want is that the alert message appears only once when the 7000 value is met and then fires no more. (At the moment, I get an incessant stream of alerts once 7000 is met.)

Is there a way of doing this?

Answer 1

Simple flag to determine if you’ve alerted:

var alerted = false;
// ...
if(path.length >= 7000 && !alerted) {
    alert("OVER 7000");
    alerted = true;
}

Or if you post how you’re looping and incrementing path.length, you can probably do something with a while loop and a break.
