【参加讨论】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>
10. 网页将不能被另存为
<noscript><iframe src=*.html></iframe></noscript>
11. <input type=button value=查看网页源代码
onclick="window.location = "view-source:"+ "http://www.pconline.com.cn"">
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;
}
alert("top="+t+"/nleft="+l);
}
</script>
//vbscript
<script language="vbscript"><!--
function getie()
dim t,l,a,b
set a=document.all.img1
t=document.all.img1.offsettop
l=document.all.img1.offsetleft
while a.tagname<>"body"
set a = a.offsetparent
t=t+a.offsettop
l=l+a.offsetleft
wend
msgbox "top="&t&chr(13)&"left="&l,64,"得到控件的位置"
end function
--></script>
14. 光标是停在文本框文字的最后
<script language="javascript">
function cc()
{
var e = event.srcelement;
var r =e.createtextrange();
r.movestart("character",e.value.length);
r.collapse(true);
r.select();
}
</script>
<input type=text name=text1 value="123" onfocus="cc()">
15. 判断上一页的来源
javascript:
document.referrer
16. 最小化、最大化、关闭窗口
<object id=hh1 classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<param name="command" value="minimize"></object>
<object id=hh2 classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<param name="command" value="maximize"></object>
<object id=hh3 classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<param name="command" value="close"></object>
<input type=button value=最小化 onclick=hh1.click()>
<input type=button value=最大化 onclick=hh2.click()>
<input type=button value=关闭 onclick=hh3.click()>
本例适用于ie
17.屏蔽功能键shift,alt,ctrl
<script>
function look(){
if(event.shiftkey)
alert("禁止按shift键!"); //可以换成alt ctrl
}
document.onkeydown=look;
</script>
18. 网页不会被缓存
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache, must-revalidate">
<meta http-equiv="expires" content="wed, 26 feb 1997 08:21:57 gmt">
或者<meta http-equiv="expires" content="0">
