刚刚在网上找到的一些javascript脚本的常用的方法, 整理
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
<script language="javascript"><!--
if (window == top)top.location.href = "frames.htm"; //frames.htm为框架网页
// --></script>
<SCRIPT LANGUAGE=javascript><!--
if (top.location != self.location)top.location=self.location;
// --></SCRIPT>
" <noscript><iframe>onclick="window.location = 'view-source:'+ 'http://www.csdn.net/'">
<% if Request.ServerVariables("HTTP_X_FORWARDED_FOR")<>"" then
response.write "<font color=#FF0000>您通过了代理服务器,"& _
"真实的IP为"&Request.ServerVariables("HTTP_X_FORWARDED_FOR")
end if
%>
<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>
<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>
<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 value="123" >
asp:
request.servervariables("HTTP_REFERER")
document.referrer
<object classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
<param value="Minimize"></object>
<object classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
<param value="Maximize"></object>
<OBJECT classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<PARAM value="Close"></OBJECT>
<input type=button value=最大化
<input type=button value=关闭
本例适用于IE

<div>(division)用来定义大段的页面元素,会产生转行
<span>用来定义同一行内的元素,跟<div>的唯一区别是不产生转行
<layer>是ns的标记,ie不支持,相当于<div>
<body >
让竖条没有:
<body style='overflow:scroll;overflow-y:hidden'>
</body>
让横条没有:
<body style='overflow:scroll;overflow-x:hidden'>
</body>
两个都去掉?更简单了
<body scroll="no">
