var l=e.offsetLeft;
while(e=e.offsetParent)
alert("top="+t+"/nleft="+l);
}


//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
-->

14. 光标是停在文本框文字的最后
<script language="#">

{
var e = event.srcElement;

r.moveStart("character",e.value.length);
r.collapse(true);
r.select();
}

<input type=text name=text1 value="123" >

<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 .Click()>
<input type=button value=最大化 .Click()>
<input type=button value=关闭 .Click()>
本例适用于IE

function look(){
if(event.shiftKey)

}
document.;

或者<META HTTP-EQUIV="expires" C>

19.怎样让表单没有凹凸感?
<input type=text style="border:1 solid #000000">

<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 >

22.不要滚动条?
让竖条没有:

两个都去掉?更简单了
<body scroll="no">

28. 检查一段字符串是否全由数字组成

alert(checkNum("123214214a1")
// -->

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 >
</textarea>

32. 日期减去天数等于第二个日期
<script language=#>
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"
}
