Question

Lets say we have a js function which shows a pop up on a button click. But if the button is clicked twice in a hurry it show two popups. Is there any way to prevent alert to show two pop ups when the button is clicked twice in a hurry?

Answer 1

you could set a variable to store a flag to say the alert is already been shown?

//outside the event
var flagShown = false;

// in the event
if(!flagShown){
alert();
flagShow = true;
}

I havent tested this code…

Edit: this will make it show only once.
You would have to reset the flag based on a timer or on some other event.
