Execute a function to track (Facebook & Line...) iFrame's click

iframe-tracking.js

<!--
@Author: Nhan Nguyen
@Description: The library iframetracker is good, but because the script to generate iframe is asynchronous, 
  so we can't setup $(document).ready() work properly.
The solution is combined:
 - Track by tagName is IFRAME for the first click
 - Then, track by iframeTracker for nth times click
