禁用右键菜单

1、右键无任何反应

第一种

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

第二种

document.oncontextmenu = function (event){if(window.event){event = window.event;}try{var the = event.srcElement;if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){return false;}return true;}catch (e){return false;}}

2.弹窗提示并变成空白页

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'; }}

禁止F12审查元素

1、按F12无任何反应

document.onkeydown = function(){ if(window.event && window.event.keyCode == 123) { event.keyCode=0; event.returnValue=false; } if(window.event && window.event.keyCode == 13) { window.event.keyCode = 505; } if(window.event && window.event.keyCode == 8) { alert(str+"\n请使用Del键进行字符的删除操作！"); window.event.returnValue=false; }}

2、按F12弹窗提示

document.onkeydown = function(){ if(window.event && window.event.keyCode == 123) { alert("F12被禁用"); event.keyCode=0; event.returnValue=false; } if(window.event && window.event.keyCode == 13) { window.event.keyCode = 505; } if(window.event && window.event.keyCode == 8) { alert(str+"\n请使用Del键进行字符的删除操作！"); window.event.returnValue=false; }}

3、按F12空白页

第一种

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();

第二种

document.onkeydown = function(){ if(window.event && window.event.keyCode == 123) { window.location="about:blank"; //将当前窗口跳转置空白页 event.keyCode=0; event.returnValue=false; } if(window.event && window.event.keyCode == 13) { window.event.keyCode = 505; } if(window.event && window.event.keyCode == 8) { alert(str+"\n请使用Del键进行字符的删除操作！"); window.event.returnValue=false; }}

4、按F12关闭当前窗口

document.onkeydown = function(){ if(window.event && window.event.keyCode == 123) { window.close(); //关闭当前窗口(防抽) event.keyCode=0; event.returnValue=false; } if(window.event && window.event.keyCode == 13) { window.event.keyCode = 505; } if(window.event && window.event.keyCode == 8) { alert(str+"\n请使用Del键进行字符的删除操作！"); window.event.returnValue=false; }}

禁止复制

document.oncopy = function (event){if(window.event){event = window.event;}try{var the = event.srcElement;if(!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){return false;}return true;}catch (e){return false;}}

禁止选中

document.onselectstart = function (event){if(window.event){event = window.event;}try{var the = event.srcElement;if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){return false;}return true;} catch (e) {return false;}}

禁止Ctrl+S网页另存为

 document.onkeydown = function(){ //禁止ctrl+s if (event.ctrlKey && window.event.keyCode==83){ return false; } }

本技术不能100%防止网页被扒
