JS step based procedural execution tool. Use this when you need to wait for something to be available on your page before executing something else

queue(step1, step2[, step3, .., stepN])

step1 Function that returns true or false. It will be called multple times until it returns true, or the limit of calls is made. step2 Function that returns true or false. Same as step1. To run this once, return true at the bottom of the function.

Use the queue.min.js file, copy and paste the code for var queue. queue.exists is an optional addon.

queue(function(){
  //step 1
  return jQuery && jQuery("#button");
}, function(){
  jQuery("#button").on("click", function(){ 
     console.log("Clicked");
  });
  // Always return true on the last step, otherwise this will be called multiple times
  return true;
});

Checks if something exists, based on brototype.doYouEven() [https://github.com/letsgetrandy/brototype]

queue.exists(varToCheck)

varToCheck A string using dot notation that describes a variable somewhere in JS land

Copy the queue.exists function from queue.min.js

queue(function(){
  //step 1
  return queue.exists("CT.ABE.Step1.Reservation.Cloud.prototype.OnSuccess");
}, function(){
  window.mySuccess = CT.ABE.Step1.Reservation.Cloud.prototype.OnSuccess;
  return true;
});
