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

11. <input type=button value=查看网页源代码
onclick="window.location = "view-source:" "http://www.blogjava.net/cyanbomb/"">

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:cyanbomb@gmail.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]="http://www.blogjava.net/cyanbomb/"
autourl[2]="http://www.blogjava.net/cyanbomb/"

41、email地址的分割
把如下代码加入<body>区域中
<a href="mailto:cyanbomb@gmail.com">cyanbomb@gmail.com</a>

42、流动边框效果的表格
把如下代码加入<body>区域中
<SCRIPT>
l=Array(6,7,8,9,’a’,’b’,’b’,’c’,’d’,’e’,’f’)
Nx=5;Ny=35
t="<table border=0 cellspacing=0 cellpadding=0 height=" ((Nx 2)*16) "><tr>"
for(x=Nx;x<Nx Ny;x )
t ="<td width=16 id=a_mo" x ">　</td>"
t ="</tr><tr><td width=10 id=a_mo" (Nx-1) ">　</td><td colspan=" (Ny-2) " rowspan=" (Nx) ">　</td><td width=16 id=a_mo" (Nx Ny) "></td></tr>"
for(x=2;x<=Nx;x )
t ="<tr><td width=16 id=a_mo" (Nx-x) ">　</td><td width=16 id=a_mo" (Ny Nx x-1) ">　</td></tr>"
t ="<tr>"
for(x=Ny;x>0;x--)
t ="<td width=16 id=a_mo" (x Nx*2 Ny-1) ">　</td>"
document.write(t "</tr></table>")
var N=Nx*2 Ny*2
function f1(y){
for(i=0;i<N;i ){
c=(i y)%20;if(c>10)c=20-c
document.all["a_mo" (i)].bgColor="’#0000" l[c] l[c] "’"}
y
setTimeout(’f1(’ y ’)’,’1’)}
f1(1)
</SCRIPT>

43、JavaScript主页弹出窗口技巧
窗口中间弹出
<script>
window.open("http://www.blogjava.net/cyanbomb/","","width=400,height=240,top=" (screen.availHeight-240)/2 ",left=" (screen.availWidth-400)/2);
</script>
============
<html>
<head>
<script language="LiveScript">
function WinOpen() {
    msg=open("","DisplayWindow","toolbar=no,directories=no,menubar=no");
    msg.document.write("<HEAD><TITLE>哈 罗!</TITLE></HEAD>");
    msg.document.write("<CENTER><H1>酷 毙 了!</H1><h2>这 是<B>JavaScript</B>所 开 的 视 窗!</h2></CENTER>");
}
</script>
</head>
<body>
<form>
<input type="button" name="Button1" value="Push me" onclick="WinOpen()">
</form>
</body>
</html>

==============

一、在下面的代码中，你只要单击打开一个窗口，即可链接到赛迪网。而当你想关闭时，只要单击一下即可关闭刚才打开的窗口。
代码如下：
<SCRIPT language="JavaScript">
<！--
function openclk() {
another=open(’http://www.blogjava.net/cyanbomb/’，’NewWindow’);
}
function closeclk() {
another.close();
}
//-->
</SCRIPT>
<FORM>
<INPUT TYPE="BUTTON" NAME="open" value="打开一个窗口" onClick="openclk()">
<BR>
<INPUT TYPE="BUTTON" NAME="close" value="关闭这个窗口" onClick="closeclk()">
</FORM>

　　二、上面的代码也太静了，为何不来点动感呢？如果能给页面来个降落效果那该多好啊！
代码如下：
<script>
function drop(n) {
if(self.moveBy){
self.moveBy (0，-900);
for(i = n; i > 0; i--){
self.moveBy(0，3);
}
for(j = 8; j > 0; j--){
self.moveBy(0，j);
self.moveBy(j，0);
self.moveBy(0，-j);
self.moveBy(-j，0);
}
}
}
</script>
<body onLoad="drop(300)">

　　三、讨厌很多网站总是按照默认窗口打开，如果你能随心所欲控制打开的窗口那该多好。
代码如下:
<SCRIPT LANGUAGE="JavaScript">
<！--***gin
function popupPage(l， t， w， h) {
var windowprops = "location=no，scrollbars=no，menubars=no，toolbars=no，resizable=yes"
"，left=" l "，top=" t "，width=" w "，height=" h;
var URL = "http://www.blogjava.net/cyanbomb/";
popup = window.open(URL，"MenuPopup"，windowprops);
}
// End -->
</script>
<table>
<tr>
<td>
<form name=popupform>
<pre>
打开页面的参数<br>
离开左边的距离: <input type=text name=left size=2 maxlength=4> pixels
离开右边的距离: <input type=text name=top size=2 maxlength=4> pixels
窗口的宽度: <input type=text name=width size=2 maxlength=4> pixels
窗口的高度: <input type=text name=height size=2 maxlength=4> pixels
</pre>
<center>
<input type=button value="打开这个窗口！" onClick="popupPage(this.form.left.value， this.form.top.value， this.form.width.value， this.form.height.value)">
</center>
</form>
</td>
</tr>
</table>你只要在相对应的对话框中输入一个数值即可，将要打开的页面的窗口控制得很好。

44、页面的打开移动
把如下代码加入<body>区域中
<SCRIPT LANGUAGE="JavaScript">
<!--***gin
for (t = 2; t > 0; t--) {
for (x = 20; x > 0; x--) {
for (y = 10; y > 0; y--) {
parent.moveBy(0,-x);
   }
}
for (x = 20; x > 0; x--) {
for (y = 10; y > 0; y--) {
parent.moveBy(0,x);
   }
}
for (x = 20; x > 0; x--) {
for (y = 10; y > 0; y--) {
parent.moveBy(x,0);
   }
}
for (x = 20; x > 0; x--) {
for (y = 10; y > 0; y--) {
parent.moveBy(-x,0);
     }
   }
}
//-->

//   End -->
</script>

45、显示个人客户端机器的日期和时间
<script language="LiveScript">
<!-- Hiding
   today = new Date()
   document.write("现 在 时 间 是： ",today.getHours(),":",today.getMinutes())
   document.write("<br>今 天 日 期 为： ", today.getMonth() 1,"/",today.getDate(),"/",today.getYear());
// end hiding contents -->
</script>

46、自动的为你每次产生最後修改的日期了：
<html>
<body>
This is a simple HTML- page.
<br>
Last changes:
   <script language="LiveScript">
   <!--   hide script from old browsers
     document.write(document.lastModified)
   // end hiding contents -->
   </script>
</body>
</html>

47、不能为空和邮件地址的约束：
<html>
<head>
<script language="JavaScript">
<!-- Hide

function test1(form) {
   if (form.text1.value == "")
     alert("您 没 写 上 任 何 东 西， 请 再 输 入 一 次 !")
   else {
    alert("嗨 " form.text1.value "! 您 已 输 入 完 成 !");
   }
}

function test2(form) {
   if (form.text2.value == "" ||
       form.text2.value.indexOf(’@’, 0) == -1)
         alert("这 不 是 正 确 的 e-mail address! 请 再 输 入 一 次 !");
   else alert("您 已 输 入 完 成 !");
}
// -->
</script>
</head>

<body>
<form name="first">
Enter your name:<br>
<input type="text" name="text1">
<input type="button" name="button1" value="输 入 测 试" onClick="test1(this.form)">
<P>
Enter your e-mail address:<br>
<input type="text" name="text2">
<input type="button" name="button2" value="输 入 测 试" onClick="test2(this.form)">
</body>

48、跑马灯
<html>
<head>
<script language="JavaScript">
<!-- Hide
var scrtxt="怎麽样 ! 很酷吧 ! 您也可以试试." "Here goes your message the visitors to your page will " "look at for hours in pure fascination...";
var lentxt=scrtxt.length;
var width=100;
var pos=1-width;
function scroll() {
   pos ;
   var scroller="";
   if (pos==lentxt) {
     pos=1-width;
   }
   if (pos<0) {
     for (var i=1; i<=Math.abs(pos); i ) {
       scroller=scroller " ";}
     scroller=scroller scrtxt.substring(0,width-i 1);
   }
   else {
     scroller=scroller scrtxt.substring(pos,width pos);
   }
   window.status = scroller;
   setTimeout("scroll()",150);
   }
//-->
</script>
</head>
<body onLoad="scroll();return true;">
这里可显示您的网页 !
</body>
</html>

49、在网页中用按钮来控制前页，后页和主页的显示。
<html>
<body>
<FORM NAME="buttonbar">
      <INPUT TYPE="button" VALUE="Back" onClick="history.back()">
      <INPUT TYPE="button" VALUE="JS- Home" onClick="location=’script.html’">
      <INPUT TYPE="button" VALUE="Next" onCLick="history.forward()">
</FORM>
</body>
</html>

50、查看某网址的源代码
把如下代码加入<body>区域中
<SCRIPT>
function add()
{
var ress=document.forms[0].luxiaoqing.value
window.location="view-source:" ress;
}
</SCRIPT>

输入要查看源代码的URL地址:
<FORM><input type="text" name="luxiaoqing" size=40 value="http://"></FORM>
<FORM><br>
<INPUT type="button" value="查看源代码" onClick=add()>
</FORM>

51、title显示日期

var isnDay = new
Array("星期日","星期一","星期二","星期三","星期四","星期五","星期六","星期日");
today = new Date () ;
Year=today.getYear();
Date=today.getDate();
if (document.all)
document.title="今天是: " Year "年" isnMonth[today.getMonth()] Date "日" isnDay[today.getDay()]
//--hide-->
</script>

52、显示所有链接
把如下代码加入<body>区域中
<script language="JavaScript1.2">
<!--
function extractlinks(){
var links=document.all.tags("A")
var total=links.length
var win2=window.open("","","menubar,scrollbars,toolbar")
win2.document.write("<font size=’2’>一共有" total "个连接</font><br>")
for (i=0;i<total;i ){
win2.document.write("<font size=’2’>" links[i].outerHTML "</font><br>")
}
}
//-->
</script>
<input type="button" onClick="extractlinks()" value="显示所有的连接">

53、回车键换行
把如下代码加入<body>区域中
<script type="text/javascript">                
function handleEnter (field, event) {
   var keyCode = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode;
   if (keyCode == 13) {
    var i;
    for (i = 0; i < field.form.elements.length; i )
     if (field == field.form.elements[i])
      break;
    i = (i 1) % field.form.elements.length;
    field.form.elements[i].focus();
    return false;
   }
   else
   return true;
}      

</script>
