Convert Classic GA integrations to work with new Universal or GTM
// Code Example taken from Jeff Pierce's dataLayer Inspector+ Chrome Extension
// https://chrome.google.com/webstore/detail/analytics-pros-datalayer/kmcbdogdandhihllalknlcjfpdjcleom?hl=en-US
// create the handler object, and initialize the _gaq array
var a = window["_gaq"] = window["_gaq"] || [];
// for Data Layer Support:
window.dataLayer = window.dataLayer || [];
// b() is where you invoke business logic as a result of data pushed in _gaq

iampatgrady / Tracking Incremental Search.js
Last active November 26, 2021 22:41
The script tracks search experiences that update automatically as you type. Known as Incremental Search in software and As-You-Type in web applications. This solution offers a way to track the value as a timeout expires after keypress. There is logic to prevent redundant events from firing.
/*
* Based on example at https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/clearTimeout
* Usage: edit config variables, copy+paste into JS console, type in search field and wait for dataLayer push
