基于jquery的禁用右键、文本选择功能、复制按键的实现代码

  //禁用右键、文本选择功能、复制按键

  $(document).bind(“contextmenu”,function(){return false;});

  $(document).bind(“selectstart”,function(){return false;});

  $(document).keydown(function(){return key(arguments[0])});

  //按键时提示警告

  function key(e){

  var keynum;

  if(window.event){

  keynum = e.keyCode; // IE

  }else if(e.which){

  keynum = e.which; // Netscape/Firefox/Opera

  }

  if(keynum == 17){

  alert(“禁止复制内容!”);

  return false;

  }

  }

  //禁用右键、文本选择功能、复制按键

  $(document).bind("contextmenu",function(){return false;});

  $(document).bind("selectstart",function(){return false;});

  $(document).keydown(function(){return key(arguments[0])});

  //按键时提示警告

  function key(e){

  var keynum;

  if(window.event) // IE

  {

  keynum = e.keyCode;

  }

  else if(e.which) // Netscape/Firefox/Opera

  {

  keynum = e.which;

  }

  if(keynum == 17){ alert("禁止复制内容!");return false;}

  }
