Detect AdBlocker Using JavaScript

To Detect AdBlocker It Takes Only Two Steps:-

  1. Make a HTML file and define markup and scripting
  2. Make a js file and define scripting for adblocker

Step 1. Make a HTML file and define markup and scripting

We make a HTML file and save it with a name detect_adblocker.html

<script type="text/javascript">
 var adblock = true;
<script type="text/javascript" src="adframe.js"></script>
<script type="text/javascript">
 alert("Please Disable AdBlocker To View The Page");
<div id="wrapper">
<p>You Webpage Content</p>

In this step we create a variable called adblock and set it to true and add 'adframe.js' file. Adblocker working is very simple it detects any external file having 'ad' or ad related phrase in file name then it block `that file or url from running in that webpage.

So in our case if adblocker is enabled then it blocks our 'adframe.js' file and remain our adblock variable to true and if the adblock is disabled then our 'adframe.js' file will run and our adblock will become false.

After then we check if our adblock variable value is true then display error message and hide the webpage content.You may also like Detect URL In Input Using jQuery.
