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)
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

<param value="Minimize"></object>
<object id=hh2 classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
<param value="Maximize"></object>
<OBJECT id=hh3 classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<PARAM VALUE="Close"></OBJECT>
<input type=button value=最小化 οnclick=hh1.Click()>
<input type=button value=最大化 οnclick=hh2.Click()>
<input type=button value=封锁 οnclick=hh3.Click()>

19.奈何让表单没有凹凸感？
<input type=text>
或
<input type=text></textarea>
20.<div><span>&<layer>的区别？
<div>(division)用来界说大段的页面元素，会发生转行
<span>用来界说同一行内的元素，跟<div>的独一区别是不发生转行
<layer>是ns的标志，ie不支持，相当于<div>
21.让弹出窗口老是在最上面:
<body οnblur="this.focus();">
22.不要转动条?
让竖条没有:
<body>
</body>
让横条没有:
<body>
</body>
两个都去掉？更简朴了
<body scroll="no">
</body>
23.奈何去掉图片链接点击后，图片周围的虚线？
<a href="#" onFocus="this.blur()"><img src="http://blog.csdn.net/blog/logo.jpg" border=0></a>
24.电子邮件处理惩罚提交表单
<form method="post" action="mailto:****@***.com" enctype="text/plain">

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巨细
<body οnlοad="top.resizeTo(300,200);">
打开页面的位置<body οnlοad="top.moveBy(300,200);">
27.在页面中如何插手不是满铺的配景图片,拉动页面时配景图不动
<STYLE>
body
{background-image:url(/blog/logo.gif); background-repeat:no-repeat;
background-position:center;background-attachment: fixed}
</STYLE>
28. 查抄一段字符串是否全由数字构成
<script language="Javascript"><!--
function checkNum(str){return str.match(//D/)==null}
alert(checkNum("1232142141"))
alert(checkNum("123214214a1"))
// --></script>
29. 得到一个窗口的巨细
document.body.clientWidth; document.body.clientHeight
30. 怎么判定是否是字符
if (/[^/x00-/xff]/g.test(s)) alert("含有汉字");
else alert("全是字符");
31.TEXTAREA自适应文字行数的几多
<textarea rows=1 name=s1 cols=27 onpropertychange="this.style.posHeight=this.scrollHeight">
</textarea>
32. 日期减去天数便是第二个日期
<script language=Javascript>
function cc(dd,dadd)
{
//可以加上错误处理惩罚
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 type="radio" value="style" checked>Style
<INPUT type="radio" value="barcode">Barcode
<INPUT type="button" value="check" οnclick="checkme()">
</BODY></HTML>
34.剧本永不堕落
<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 οnkeydοwn="if(event.keyCode==13)event.keyCode=9">
