简介

在一次工作中，所做的项目要求页面中不能右击，不能打开F12。一般来说可以禁用F12的按键，但是可以通过开发者工具进入。经过个人实验，以下方法适用于谷歌浏览器、火狐浏览器，以及使用谷歌内核的浏览器（如QQ浏览器、搜狗浏览器等），IE忘了是否支持，自我感觉是目前比较齐全的了。

//禁止鼠标右击
      document.oncontextmenu = function() {
        event.returnValue = false;
      };
      //禁用开发者工具F12
      document.onkeydown = document.onkeyup = document.onkeypress = function(event) {
        let e = event || window.event || arguments.callee.caller.arguments[0];
        if (e && e.keyCode == 123) {
          e.returnValue = false;
          return false;
        }
      };
      let userAgent = navigator.userAgent;
      if (userAgent.indexOf("Firefox") > -1) {
        let checkStatus;
        let devtools = /./;
        devtools.toString = function() {
          checkStatus = "on";
        };
        setInterval(function() {
          checkStatus = "off";
          console.log(devtools);
          console.log(checkStatus);
          console.clear();
          if (checkStatus === "on") {
            let target = "";
            try {
              window.open("about:blank", (target = "_self"));
            } catch (err) {
              let a = document.createElement("button");
              a.onclick = function() {
                window.open("about:blank", (target = "_self"));
              };
              a.click();
            }
          }
        }, 200);
      } else {
        //禁用控制台
        let ConsoleManager = {
          onOpen: function() {

              isOpened = false;

                  self.onOpen();
                  isOpening = true;
                }

              }
            }, 200);
