网站防扒JS代码代码合集

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';
    }
}

禁止元素审查

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;
  }
}

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;
  }
}

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;
  }
  }
