js代码屏蔽开发者工具

防止使用开发者工具对代码进行调试

js可以加入如下代码:

  1 <script type="text/javascript">
  2 
  3 //禁止鼠标右击
  4    document.oncontextmenu = function() {
  5      event.returnValue = false;
  6    };
  7    //禁用开发者工具F12
  8    document.onkeydown = document.onkeyup = document.onkeypress = function(event) {
  9      let e = event || window.event || arguments.callee.caller.arguments[0];
 10      if (e && e.keyCode == 123) {
 11        e.returnValue = false;
 12        return false;
 13      }
 14    };
 15    let userAgent = navigator.userAgent;
 16    if (userAgent.indexOf("Firefox") > -1) {
 17      let checkStatus;
 18      let devtools = /./;
 19      devtools.toString = function() {
 20        checkStatus = "on";
 21      };
 22      setInterval(function() {
 23        checkStatus = "off";
 24        console.log(devtools);
 25        console.log(checkStatus);
 26        console.clear();
 27        if (checkStatus === "on") {
 28          let target = "";
