javascript常用技巧
文本框焦点问题 网页按钮的特殊颜色等常用的一些网站中常用到的一些不得不会的一些知识点。1.文本框焦点问题转载自：http://www.jb51.net/article/16240.htm
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>
共和国
</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">

.style4 { font-size: 12px; font-weight: bold; background: url(image/buttonbg2.gif); border: 0px 0; width:
60px; height: 22px}
-->
</style>
本例的按钮代码如下：
<input type="submit" name="Submit2" value="提 交" onmouseover="this.className='style4'"
onmouseout="this.className='style3'" class="style3">
19.打印页面
<div align="center"><a class=content href="javascript:doPrint();">打印本稿</a></div>
20.可以直接写html语言
document.write("");
21.改变下拉框的颜色

22.转至目标URL
window.location=http://blog.csdn.net/lxs5i5j/archive/2007/01/22/"http://guoguo"
23.传递该object的form
UpdateSN('guoqiang99267',this.form)
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(){

}
< /script >
28.可以比较字符的大小
char=post.charAt(i);
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>
