 Array.prototype.myPush=function(value){
       this.push(value);
       alert('value added');
    
    }
    var arr=[1,2];
    arr.myPush(3)

METHOD 1 You can modify the code where you are pushing the array

In your code where you are pushing the value inside the array add the piece of code to trigger the event.

var arr = [];
arr.push(1);
// Trigger Event Here

METHOD 2 You can not modify the code where you are pushing the array

// arr is the global array you want to check
var intArr = setInterval(function(){
  if(arr.length>0)
  {
    // Trigger Event.
    clearInterval(intArr); // To stop setInterval() when event is triggered
  }
},100);
