<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){

if(event.ctrlKey){

return false;}
