  • javascript 实现禁止右键,复制,选取文本 (兼容firefox,IE,chrome等主流浏览器)

    1. JS 禁止右键

    <script type="text/javascript">document.oncontextmenu=function(e){return false;}</script>
    
    <body onselectstart="return false">
    ......
    2. CSS 禁止复制和选取
    如果让整个页面都禁止选择  
    <style type="text/css">
    body {
        -webkit-touch-callout: none;
        -webkit-user-select: none;
        -khtml-user-select: none;
        -moz-user-select: none;
        -ms-user-select: none;
        user-select: none;  
    }
    </style>  

    如果是局部

    Html代码

    <style type="text/css">
    .unselectable {
       -moz-user-select: -moz-none;
       -khtml-user-select: none;
       -webkit-user-select: none;
    
       /*
         Introduced in IE 10.
         See http://ie.microsoft.com/testdrive/HTML5/msUserSelect/
       */
       -ms-user-select: none;
       user-select: none;
    }
    </style>

    3. 完整实例:

    <style type="text/css">  
    body {  
        -webkit-touch-callout: none;  
        -webkit-user-select: none;  
        -khtml-user-select: none;  
        -moz-user-select: none;  
        -ms-user-select: none;  
        user-select: none;  
    }  
    </style>  
    <script langauge="javascript">  
    document.oncontextmenu=function(e){return false;}  
    </script>   
    </head>  
      
    <body onselectstart="return false">  
    ... ...

    }
    
    function iEsc(){ return false; }
    function iRec(){ return true; }
    function DisableKeys() {
        if(event.ctrlKey || event.shiftKey || event.altKey)  {
        window.event.returnValue=false;
        iEsc();}
    }
    
    document.ondragstart=iEsc;
    document.onkeydown=DisableKeys;
    document.oncontextmenu=iEsc;
    
    if (typeof document.onselectstart !="undefined") document.onselectstart=iEsc;
    else
    {
        document.onmousedown=iEsc;
        document.onmouseup=iRec;
    }
    
    function DisableRightClick(e)
    {
        if (window.Event){ if (e.which == 2 || e.which == 3) iEsc();}
        else
            if (event.button == 2 || event.button == 3)
            {
                event.cancelBubble = true
                event.returnValue = false;
                iEsc();
            }
    }
