Javascript - Prevent Function From Executing Multiple Times

I have a function which is executed on a click (or taphold) because I am working with Cordova. The problem is that a function calls on the next object from Parse.com which shows i

Solution 1:

You are experiencing "bounce", a problem caused by one impact registering multiple times in short succession. To get around it, you need to put a very short timeout on your function. (20ms or so) You can either use a third-party library such as LoDash which has many useful utility functions such as _.debounce which performs this, or you can do it yourself like this:

var lastClick = 0;
var delay = 20;

functiondoClick() {
  if (lastClick >= (Date.now() - delay))
    return;
  lastClick = Date.now();

  // do thingsalert("Hello!");
}
<buttononclick="doClick()">Push me</button>

Solution 2:

This is a similar code that I use regularly.

const delay = 500; // anti-rebound for 500mslet lastExecution = 0;

functionmyFunction(){
    if ((lastExecution + delay) < Date.now()){
       // execute my lines
       lastExecution = Date.now() 
    }
}
