基于jquery的禁用右键、文本选择功能、复制按键的实现代码_jquery

同时适合IE、firefox、谷歌浏览器下适用，经过筛选代码如下：

复制代码 代码如下:

//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;}
        }
