Stop Javascript Function execution from another Function

Question

Is there any way to stop the execution of a called function from another function?

I have following code:-

function MainFunction() { //a long code that r         


        

Answer 1

You can pass an argument, like cancel, whenever you are calling the MainFunction. So, if you want the function to start, you pass in an arguement '0', and if you want it to stop, you can call the function again with an arguement which is not '0', like '1'. Here is a working example:

function MainFunction(cancel) {
var yourcode;
  if (cancel == 0) {
    yourCode = setInterval(function() {
      //Put your code here, this is an example:
      document.getElementById('div').style.color = "red";
    }, 1);
  }
  if (cancel == 1) {
    clearInterval(yourCode);
    document.getElementById('div').style.color = "black";
  }
}

  
    
  
  
    Start
    Stop
    
This division can change colour
