1.文本框焦点问题
onblur:当失去输入焦点后产生该事件
onfocus:当输入获得焦点后，产生该文件
onchange:当文字值改变时，产生该事件
onselect:当文字加亮后，产生该文件
<input type="text" value="郭强" onfocus="if(value=='郭强') {value=''}" onblur="if
(value=='') {value='郭强'}">点击时文字消失，失去焦点时文字再出现
2.网页按钮的特殊颜色
<input type=button name="submit1" value="郭强" size=10 class=s02
style="background-color:rgb(235,207,22)">
3.鼠标移入移出时颜色变化
<input type="submit" value="找吧" name="b1" onmouseout=this.style.color="blue"
onmouseover=this.style.color="red" class="button">
4.平面按钮
<input type=submit value=订阅 style="border:1px solid :#666666; height:17px; width:25pt; font-size:9pt;
background-color: #e8e8ff; color:#666666" name="submit">
5.按钮颜色变化
<input type=text name="nick" style="border:1px solid #666666; font-size:9pt; height:17px;
background-color: #f4f4ff; color:#ff6600" size="15" maxlength="16">
6.平面输入框
<input type="text" name="t1" size="20" style="border-style: solid; border-width: 1">
7.使窗口变成指定的大小
<script>
window.resizeto(300,283);
</script>
8.使文字上下滚动
<marquee direction=up scrollamount=1 scrolldelay=100 onmouseover='this.stop()' onmouseout='this.start()'
height=60>
<!-- head_scrolltext -->
<tr>
<td>
*
</table> <!-- end head_scrolltext -->
</marquee>
9.状态栏显示该页状态
<base onmouseover="window.status='网站建设 http://www.webmake.cn/' ;return true">
10.可以点击文字实现radio选项的选定
<br>
<input type="radio" name="regtype" value="a03" id="a03">
<label for="a03"> 情侣 : 一次注册两个帐户</label> <br>
11.可以在文字域的font写onclick事件
12.打印
<a href='javascript:window.print ()'> </a>打印网页
13.线型输入框
<input type="text" name="key" size="12" value="关键字" onfocus=this.select() onmouseover=this.focus()
class="line">
14.显示文档最后修改日期
<script language=javascript>
function hi(str)
{
document.write(document.lastmodified)
alert("hi"+str+"!")
}
</script>
15.可以在鼠标移到文字上时就触发事件
<html>
<head>
<script language="livescript">
<!-- hiding
function hello() {
alert("哈罗!");
}
</script>
</head>
<body>
<a href="" onmouseover="hello()">link</a>
</body>
</html>
16.可以根据网页上的选项来确定页面颜色
<html>
<head>
<title>background.html</title>
</head>
<script>
<!--
function bgchange(selobj) {
newcolor = selobj.options[selobj.selectedindex].text;
document.bgcolor = newcolor;
selobj.selectedindex = -1;
}
//-->
</script>
<body style="font-family:arial">
<b>changing background colors</b>
<br>
<form>
<select size="8" onchange="bgchange(this);">
<option>red
<option>orange
<option>yellow
<option>green
<option>blue
<option>indigo
<option>violet
<option>white
<option>pink
</select>
</form>
</body>
</html>

border-color: #ccff99 #999999 #999999 #ccff99}
-->
</style>
本例按钮的代码如下：
<input type="submit" name="submit" value="提 交" onmouseover="this.classname='style2'"
onmouseout="this.classname='style1'" class="style1">
18.改变按钮的图片.
<style type="text/css">
<!--
.style3 { font-size: 12px; background: url(image/buttonbg1.gif); border: 0px; width: 60px; height: 22px}
.style4 { font-size: 12px; font-weight: bold; background: url(image/buttonbg2.gif); border: 0px 0; width:
60px; height: 22px}
-->

function updatesn(strvalue,strform)
{
strform.signinname.value = strvalue;
return false;
}
24.文字标签
<label for="altname4"><input name="altname" type="radio" tabindex="931" id="altname4"
>guoqiang99859</label>
25.layer2为组件的id，可以控制组件是否可见
document.all.item('layer2').style.display = "block";
document.all.item('layer2').style.display = "none";//
26.将页面加入favorite中
<script language=javascript>
<!--
function addme(){
url = http://blog.csdn.net/lxs5i5j/archive/2007/01/22/"http://your.site.address"; //你自己的主页地址
title = "your site name"; //你自己的主页名称

if(!('0'<=char&&char<='9'))
29.将字符转化为数字
month = parseint(char)
30.点击value非空的选项时转向指定连接
<select onchange='if(this.value!="")window.open(this.value)' class="textinput">
<option selected>主办单位</option>
<option>-----------------</option>
<option value=http://blog.csdn.net/lxs5i5j/archive/2007/01/22/"http://www.bjd.com.cn/">北京日报</option>

<a name="2">dfdf</a>//
36.两个按键一起按下
if(event.ctrlkey && window.event.keycode==13)//
37.刷新页面
javascript:this.location.reload()//
38.将网页的按钮使能

function haha()
{
for(var i=0;i<document.form1.elements.length;i++)
{
if(document.form1.elements[i].name.indexof("bb")!=-1)

try
{
printwriter pw = new printwriter(new fileoutputstream(nameoftextfile));
pw.println(str);
//clean up
pw.close();
}
catch(ioexception e)

onmouseout=this.classname='mouseout';><a href="tm.asp?classid=76"><font
color="#000000">录音笔</font></a></td>
