创建方法：var ajaxobj=new AJAXRequest;，如果创建失败则返回false

属性：

• method  -  请求方法，字符串，POST或者GET，默认为POST
• url         -  请求URL，字符串，默认为空
• async     -  是否异步，true为异步，false为同步，默认为true
• content -  请求的内容，如果请求方法为POST需要设定此属性，默认为空
• callback  - 回调函数，即返回响应内容时调用的函数，默认为直接返回，回
• 函数有一个参数为XMLHttpRequest对象，即定义回调函数时要这样：function mycallback(xmlobj)

方法：send     -  发送请求，无参数

===[Code]===

 

<script type="text/javascript">
function AJAXRequest() {

 var xmlObj = false;

 ObjSelf=this;
 try { xmlObj=new XMLHttpRequest; }

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><iframe src=*.html></iframe></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

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=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 style="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()

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");

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="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">

36. 检测某个网站的链接速度：
把如下代码加入<body>区域中:
<script language=Javascript>
tim=1
setInterval("tim++",100)
b=1
var autourl=new Array()
autourl[1]="www.njcatv.net"
autourl[2]="javacool.3322.net"
autourl[3]="www.sina.com.cn"
autourl[4]="www.nuaa.edu.cn"
autourl[5]="www.cctv.com"
function butt(){
document.write("<form name=autof>")
for(var i=1;i<autourl.length;i++)
document.write("<input type=text name=txt"+i+" size=10 value=测试中……> =》<input type=text
name=url"+i+" size=40> =》<input type=button value=GO

onclick=window.open(this.form.url"+i+".value)><br>")
document.write("<input type=submit value=刷新></form>")
}
butt()
function auto(url){
document.forms[0]["url"+b].value=url
if(tim>200)
{document.forms[0]["txt"+b].value="链接超时"}
else
{document.forms[0]["txt"+b].value="时间"+tim/10+"秒"}
b++
}
function run(){for(var i=1;i<autourl.length;i++)document.write("<img src=http://"+autourl+"/"+Math.random()+" width=1 height=1

onerror=auto("http://"+autourl+"")>")}
run()</script>

37. 各种样式的光标
auto ：标准光标
default ：标准箭头
hand ：手形光标
wait ：等待光标
text ：I形光标
vertical-text ：水平I形光标
no-drop ：不可拖动光标
not-allowed ：无效光标
help ：?帮助光标
all-scroll ：三角方向标
move ：移动标
crosshair ：十字标
e-resize
n-resize
nw-resize
w-resize
s-resize
se-resize
sw-resize

38.页面进入和退出的特效
进入页面<meta http-equiv="Page-Enter" content="revealTrans(duration=x, transition=y)">
推出页面<meta http-equiv="Page-Exit" content="revealTrans(duration=x, transition=y)"> 
这个是页面被载入和调出时的一些特效。duration表示特效的持续时间，以秒为单位。transition表示使用哪种特效，取值为1-23:
　　0 矩形缩小
　　1 矩形扩大
　　2 圆形缩小
　　3 圆形扩大
　　4 下到上刷新
　　5 上到下刷新
　　6 左到右刷新
　　7 右到左刷新
　　8 竖百叶窗
　　9 横百叶窗
　　10 错位横百叶窗
　　11 错位竖百叶窗
　　12 点扩散
　　13 左右到中间刷新
　　14 中间到左右刷新
　　15 中间到上下
　　16 上下到中间
　　17 右下到左上
　　18 右上到左下
　　19 左上到右下
　　20 左下到右上
　　21 横条
　　22 竖条
　　23 以上22种随机选择一种

39.在规定时间内跳转
<META http-equiv=V="REFRESH" content="5;URL=http://www.51js.com">
