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");
31.TEXTAREA自适应文字行数的多少
<textarea rows=1 name=s1 cols=27 onpropertychange
="this.style.posHeight=this.scrollHeight">
</textarea>
32. 日期减去天数等于第二个日期
<script language=Javascript>
function cc(dd,dadd)
{
//可以加上错误处理
var a = new Date(dd)
a = a.valueOf()
a = a - dadd * 24 * 60 * 60 * 1000
a = new Date(a)
alert(a.getFullYear() + "年" + (a.getMonth() + 1) + "月" + a.getDate() + "日")
}
cc("12/23/2002",2)
</script>
33. 选择了哪一个Radio
<HTML><script language="vbscript">
function checkme()
for each ob in radio1
if ob.checked then
window.alert ob.value
next
end function
</script><BODY>
<INPUT name="radio1" type="radio" value="/style" checked>Style
<INPUT name="radio1" type="radio" value="/blog/barcode">Barcode
<INPUT type="button" value="check" onclick="checkme()">
</BODY></HTML>
34.脚本永不出错
<SCRIPT LANGUAGE="JavaScript">
<!-- Hide
function killErrors() {
return true;
}
window.onerror = killErrors;
// -->
</SCRIPT>
35.ENTER键可以让光标移到下一个输入框
<input onkeydown="if(event.keyCode==13)event.keyCode=9">

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="/blog/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">
19.怎样让表单没有凹凸感？
<input type=text"border:1 solid #000000">
或
<input type=text style="border-left:none; border-right:none; border-top:none; border-bottom:
1 solid #000000"></textarea>
20.<div><span>&<layer>的区别？
<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>
21.让弹出窗口总是在最上面:
<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>
24.电子邮件处理提交表单
<form name="form1" method="post" action=mailto:****@***.com
enctype="text/plain">
<input type=submit>
</form>
25.在打开的子窗口刷新父窗口的代码里如何写？
window.opener.location.reload()

<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><*** src="/*.html>";</***></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
