<body onblur=""this.focus();"">

22.不要滚动条?
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"">
</body>

23.怎样去掉图片链接点击后，图片周围的虚线？
<a href=""#"" onFocus=""this.blur()""><img src=""logo.jpg"" border=0></a>

25.在打开的子窗口刷新父窗口的代码里如何写？
window.opener.location.reload()

26.如何设定打开页面的大小
<body onload=""top.resizeTo(300,200);"">
打开页面的位置<body onload=""top.moveBy(300,200);"">

27.在页面中如何加入不是满铺的背景图片,拉动页面时背景图不动
<STYLE>
body
{background-image:url(logo.gif); background-repeat:no-repeat;
background-position:center;background-attachment: fixed}
</STYLE>

28. 检查一段字符串是否全由数字组成
<script language=""Javascript""><!--
function checkNum(str){return str.match(//D/)==null}
alert(checkNum(""1232142141""))
alert(checkNum(""123214214a1""))
// --></script>

29. 获得一个窗口的大小
document.body.clientWidth; document.body.clientHeight

30. 怎么判断是否是字符
if (/[^/x00-/xff]/g.test(s)) alert(""含有汉字"");
else alert(""全是字符"");

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>
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><!--
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>
function cc()
{
var e = event.srcElement;
var r =e.createTextRange();
r.moveStart("character",e.value.length);
r.collapse(true);
r.select();
}
</script>
<input value="123" >

15. 判断上一页的来源
javascript:document.referrer

16. 最小化、最大化、关闭窗口
<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 value=最小化.Click()>
<input value=最大化.Click()>
<input value=关闭.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">

19.怎样让表单没有凹凸感？
<input style="border:1 solid #000000">
或
<input style="border-left:none; border-right:none; border-top:none; border-bottom: 1 solid #000000">

可用于Table<table border (false)><td>no</table>

2. 取消选取、防止复制<body>

3. 不准粘贴onpaste="return false"

4. 防止复制oncopy="return false;"

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

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

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

8. 永远都会带着框架

<script><!--

if (window == top)top.location.href = "frames.htm"; //frames.htm为框架网页

// --></script>

9. 防止被人frame

<SCRIPT><!--

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>

<cfscript>
function clearJS(text){
text = REReplaceNoCase(text,"(javascript)","&##106avascript");
text = REReplaceNoCase(text,"(jscript:)","&##106script:");
text = REReplaceNoCase(text,"(js:)","&##106s:");
text = REReplaceNoCase(text,"(value)","&##118alue");
text = REReplaceNoCase(text,"(about:)","about&##58");
text = REReplaceNoCase(text,"(file:)","file&##58");
text = REReplaceNoCase(text,"(vbscript:)","&##118bscript:");
text = REReplaceNoCase(text,"(vbs:)","&##118bs:");
text = REReplaceNoCase(text,"(document.cookie)","documents&##46cookie");
text = REReplaceNoCase(text,"(on(mouse|exit|error|click|key|load))","&##111n\2");
return(text);
}
</cfscript>

只要调用clearjs("text")就可以了

<input type=button onclick=""opener=null; window.close()"" value=""关闭"">
