Ad Blocker detection AKA Adblock Plus

Question

After searching Google and Stackoverflow for a few hours I could not find a solution. What I\'m trying to do is detect Adblock plus and display a simple message for now.

Answer 1

A simple Ajax call does the job:

var xmlhttp = new XMLHttpRequest()
xmlhttp.onreadystatechange = function() {
  if( xmlhttp.readyState == XMLHttpRequest.DONE ){
    if( xmlhttp.status !== 404 ){
        console.log("Blocking ads")
    }else{
        console.log("Not blocking ads")
    }
  }
}
xmlhttp.open("GET", "/498100ffe815d700cd838d1/ads/showad.js", true)
xmlhttp.send()

Or even better, without an extra HTTP overhead:

var adBlockTester = document.createElement('div');
adBlockTester.innerHTML = ' ';
adBlockTester.className = 'adsbox';
document.body.appendChild(adBlockTester);
window.setTimeout(function() {
  if( adBlockTester.offsetHeight === 0 ){
    console.log("Blocking ads")
  }else{
    console.log("Not blocking ads")
  }
  document.body.removeChild(adBlockTester);
}, 60);
