A Piece of JS for Ultimate Resistance Against Developer Tools

This post is automatically translated with LLM. The translation content has NOT been reviewed and may contain errors.

The most frustrating part of website development is having your painstakingly crafted templates ripped off using developer tools, as Chrome Dev Tools and Firebug possess immense power. (No explanation needed)

Developer tools were once invincible, until this piece of JS emerged.

function fuckyou() {
  window.location = 'http://i-xider.com/#呵呵' //Redirect current window to blank page
}
function ck() {
  console.profile()
  console.profileEnd()
  //Check if profiles contains data - if yes, someone pressed F12!
  if (console.clear) {
    console.clear()
  }
  if (typeof console.profiles == 'object') {
    return console.profiles.length > 0
  }
}
ck() //Reveal integrity
$('body').data('w', $(window).width())
$('body').data('h', $(window).height()) //Cache initial window dimensions on body
function hehe() {
  if ($.browser.msie) {
    if (
      $('body').data('w') == $(window).width() &&
      $('body').data('h') - $(window).height() > 50
    ) {
      fuckyou() // IE WQNMLGB
    }
  } else if ($.browser.mozilla) {
    if (
      window.console &&
      (console.firebug || (console.table && /firebug/i.test(console.table())))
    ) {
      fuckyou() // Firefox
    }
  } else {
    if (
      ($('body').data('w') == $(window).width() &&
        $('body').data('h') - $(window).height() > 50) ||
      (typeof console.profiles == 'object' && console.profiles.length > 0)
    ) {
      fuckyou() // Chrome and Opera
    }
  }
}
hehe() //Suggest alternative activities
window.onresize = function () {
  if (
    $('body').data('w') == $(window).width() &&
    $('body').data('h') - $(window).height() > 50
  )
    //If page height vs window height difference >50, redirect
    fuckyou()
}

This JS automatically detects if developer tools (Firebug, Chrome Dev Tools, etc.) are open in your browser. When triggered, it forcibly redirects the page to about:blank to prevent malicious code theft.

Usage:

1. Baidu Cloud CDN

<script
  type="text/javascript"
  src="//publicdn.cdn.duapp.com/js/wqnmlgb.min.js"
></script>

2. Provided by zntec.cn

<script

></script>

Of course, if your blog isn't concerned about code theft, skip this. My blog pages allow normal access to developer tools - feel free to inspect the code... (Truth be told, I need to use them myself too)
