网站防扒JS代码技术合集

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;    }    }
