• JS禁用右键,禁用打印,防止另存为


    oncontextmenu="window.event.returnValue=false" style="overflow-y: hidden; overflow-x: hidden"ajs9     leftmargin="0" topmargin="0"
    <body oncontextmenu="return false"></body>
    <!--禁止网页另存为: -->
    <noscript><iframe src=*.html></iframe></noscript>

    <!-- 禁止选择文本: -->
    <script type="text/javascript">

    var omitformtags=["input", "textarea", "select"]

    omitformtags=omitformtags.join("|")

    function disableselect(e){
    if (omitformtags.indexOf(e.target.tagName.toLowerCase())==-1)
    return false
    }

    function reEnable(){
    return true
    }

    if (typeof document.onselectstart!="undefined")
    document.onselectstart=new Function ("return false")
    else{
    document.onmousedown=disableselect
    document.onmouseup=reEnable
    }
    </script>

    <!-- 禁用右键: -->
    <script>
    function stop(){
    return false;
    }
    document.oncontextmenu=stop;
    </script>


    1. oncontextmenu="window.event.returnvalue=false" 将彻底屏蔽鼠标右键
    <table border oncontextmenu=return(false)><td>no</table> 可用于Table


    2. <body onselectstart="return false"> 取消选取、防止复制


    3. onpaste="return false" 不准粘贴


    4. oncopy="return false;" oncut="return false;" 防止复制


    5. <link rel="Shortcut Icon" href="favicon.ico"> IE地址栏前换成自己的图标


    6. <link rel="Bookmark" href="favicon.ico"> 可以在收藏夹中显示出你的图标


    7. <input style="ime-mode:-Disabled"> 关闭输入法


    8. 永远都会带着框架
    <script language="javascript"><!--
    if (window == top)top.location.href = "frames.htm"; //frames.htm为框架网页
    // --></script>


    9. 防止被人frame
    <SCRIPT LANGUAGE=javascript><!--
    if (top.location != self.location)top.location=self.location;
    // --></SCRIPT>

    11. <input type=button value=查看网页源代码
    onclick="window.location = `view-source:`+ http://www.tonightdream.com/`";>


    12.删除时确认
    <a href=`javascript:if(confirm("确实要删除吗?"location="boos.asp?&areyou=删除&page=1"`>删除</a>


    13. 取得控件的绝对位置
    //javascript
    <script language="javascript">
    function getIE(E){
    var t=e.offsetTop;
    var l=e.offsetLeft;
    while(e=e.offsetParent){
    t+=e.offsetTop;
    l+=e.offsetLeft;

    <!--右键开始-->
    <script language="JavaScript">
    <!--

    if (window.Event)
    document.captureEvents(Event.MOUSEUP);

    function nocontextmenu()
    {
    event.cancelBubble = true
    event.returnValue = false;

    return false;
    }

    function norightclick(e)
    {
    if (window.Event)
    {
    if (e.which == 2 || e.which == 3)
       return false;
    }
    else
    if (event.button == 2 || event.button == 3)
    {
       event.cancelBubble = true
       event.returnValue = false;
       return false;
    }

    }

    document.oncontextmenu = nocontextmenu; // for IE5+
    document.onmousedown = norightclick; // for all others
    //-->
       </script>
    <!-- 禁止选择文本: -->
    <script type="text/javascript">

    var omitformtags=["input", "textarea", "select"]

    omitformtags=omitformtags.join("|")

    function disableselect(e){
    if (omitformtags.indexOf(e.target.tagName.toLowerCase())==-1)
    return false
    }

    function reEnable(){
    return true
    }

    if (typeof document.onselectstart!="undefined")
    document.onselectstart=new Function ("return false")
    else{
    document.onmousedown=disableselect
    document.onmouseup=reEnable
    }
       </script>

    <script language="javascript" type="text/javascript">
    <!--
    function key(){
    if(event.shiftKey){
    window.close();}
    //禁止shift
    if(event.altKey){
    window.close();}
    //禁止alt
    if(event.ctrlKey){
    window.close();}
    //禁止ctrl
    return false;}
    //document.onkeydown=key;
    if (window.Event)
    document.captureEvents(Event.MOUSEUP);
    //swordmaple javascript article.
    //from http://www.jx165.com/
    function nocontextmenu(){
    event.cancelBubble = true
    event.returnValue = false;
    return false;}
    function norightclick(e){
    if (window.Event){
    if (e.which == 2 || e.which == 3)
    return false;}
    else
    if (event.button == 2 || event.button == 3){
    event.cancelBubble = true
    event.returnValue = false;
    return false;}
    }
    //禁止右键
    document.oncontextmenu = nocontextmenu; // for IE5+
    document.onmousedown = norightclick; // for all others
    //-->

    </script>

    ---------------

    要真正禁止打印页面是办不到的,但是如果能设置让用户打印到的是空白,也算是实现禁止打印的目的了

    <html> 
    <head><title>不可打印的页面</title> 
    <style> 
    @media print{ 
    body{display:none} 

    </style> 
    </head> 
    <body> 
    文档主要内容 
    </html>
