1.禁用浏览器右键菜单

document.oncontextmenu = new Function("return false;");

2.监听键盘事件

function mAlert() {    var fn = function () {};    fn.toString = function () {        window.location = 'about: blank';        console.log("呵呵");    }    console.log("%c", fn);//请不要删除这行};mAlert();

3.检测控制台

function mAlert() {    var fn = function () {};    fn.toString = function () {        window.location = 'about: blank';        console.log("呵呵");    }    console.log("%c", fn);//请不要删除这行};mAlert();

4.鼠标点击事件

document.onmousedown = function mdClick(event) {    var e = event || window.event || arguments.callee.caller.arguments[0];    if (e.button == 2 || e.button == 3) {        alert("呵呵");        //不建议用以下方法，易错率大        window.location = 'about: blank';    }}

5.禁止保存

 document.onkeydown = function() {        if ((e.ctrlKey) && (e.keyCode == 83)) { //ctrl+s            alert("ctrl+s被禁用");            return false;        }    }

css禁止左键右键

//左键〈body onselectstart="return false"〉//右键〈body οncοntextmenu='return false'〉
