Using dev console, click all elements of a given class on a page. Very useful for grocery store rewards pages where you can click on hundreds of coupons.

classClick.js

// Create function
function waitScrape(class_name)
{
 console.log("Starting");
 var buttons = document.getElementsByClassName(class_name);
  for(i = 0; i <= buttons.length; i++) {
    setTimeout(function () {
     // register click event
      buttons[i].click();
     // Set wait time for 3 seconds (3000 milliseconds)
    }, 3000);
  }
}

// Initiate function
waitsScrape('UnFollowUser');

Class name for Safeway is
'lt-offer-Clip ng-scope'

Class name for CVS seems to be 'coupon_status' but would recommend possibly attempting only a few at a time or perhaps implementing a timer between requests and running overnight as I am now denied access for attempting this crawl.

Implemented timer, need to see if I can simulate a "page down" event in order to load all coupons.
