Guide How to Centralize Your Landing Page Scripts in 1 File

[Nick]

In this guide, I’m going to show you how you can centralize your landing page scripts so that when you need to make changes you can do it in 1 place instead of on every single landing page you have separately.

This isn’t something that’s required if you’re using landing pages, but if definitely makes your life 200% easier. I’ve also had a few people ask me about how to do this, so I thought it would be good to make it as a guide for others.

// Get URL  Params
function getURLParameter(name) {
  return decodeURIComponent((RegExp(name  + '=' + '(.+?)(&|$)').exec(location.search) || [,  null])[1] || '');
}

// Propush
if (!getURLParameter('push')) {
   var s = document.createElement('script');
   s.src = '//oungimuk.net/act/files/micro.tag.min.js?z=1234567' + '&sw=/sw-check-permissions-c123e.js';
   s.onload = function (result) {
     switch (result) {
       case 'onPermissionDefault':
