## 167.以下组合可以正确显示汉字 ##

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

xml保存编码 xml页面指定编码

ANSI  gbk/GBK、gb2312

Unicode  unicode/Unicode

UTF-8  UTF-8

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

## 168.XML操作 ##

var x=xmldata.recordset //取得数据岛中的记录集

if(x.absoluteposition < x.recordcount) //如果当前的绝对位置在最后一条记录之前

x.movenext();     //向后移动

x.moveprevious();    //向前移动

x.absoluteposition=1;   //移动到第一条记录

x.absoluteposition=x.recordcount;//移动到最后一条记录，注意记录集x.absoluteposition是从1到记录集记录的个

数的

guoguo.innerText=xmldso.recordset(“field\_name”); //从中取出某条记录

</script>

## 169.动态修改CSS的另一种方式 ##

this.runtimeStyle.cssText = “color:\#990000;border:1px solid\#cccccc”;//

## 170.正则表达式 ##

匹配中文字符的正则表达式： \[\\u4e00-\\u9fa5\]

匹配双字节字符(包括汉字在内)：\[^\\x00-\\xff\]

应用：计算字符串的长度（一个双字节字符长度计2，ASCII字符计1）

String.prototype.len=function()\{returnthis.replace(\[^\\x00-\\xff\]/g,”aa”).length;\}

匹配空行的正则表达式：\\n\[\\s| \]\*\\r

匹配HTML标记的正则表达式：/<(.\*)>.\*<\\/\\1>|<(.\*) \\/>/

匹配首尾空格的正则表达式：(^\\s\*)|(\\s\*$)

应用：javascript中没有像vbscript那样的trim函数，我们就可以利用这个表达式来实现，如下：

String.prototype.trim =function()

return this.replace(/(^\\s\*)|(\\s\*$)/g, “”);

利用正则表达式分解和转换IP地址：

下面是利用正则表达式匹配IP地址，并将IP地址转换成对应数值的Javascript程序：

function IP2V(ip)

re=/(\\d+)\\.(\\d+)\\.(\\d+)\\.(\\d+)/g  //匹配IP地址的正则表达式

if(re.test(ip))

returnRegExp.1∗Math.pow(255,3))\+RegExp.  1 ∗ M a t h . p o w ( 255 , 3 ) ) + R e g E x p . 2\*Math.pow(255,2))+RegExp.3∗255\+RegExp.  3 ∗ 255 + R e g E x p . 4\*1

else

throw new Error(“Not a valid IP address!”)

不过上面的程序如果不用正则表达式，而直接用split函数来分解可能更简单，程序如下：

var ip=”10.100.20.168″

ip=ip.split(“.”)

alert(“IP值是：”+(ip\[0\]\*255\*255\*255+ip\[1\]\*255\*255+ip\[2\]\*255+ip\[3\]\*1))

匹配Email地址的正则表达式：\\w+(\[-+.\]\\w+)\*@\\w+(\[-.\]\\w+)\*\\.\\w+(\[-.\]\\w+)\*

匹配网址URL的正则表达式：http://(\[\\w-\]+\\.)+\[\\w-\]+(/\[\\w- ./ %&=\]\*)

//利用正则表达式去除字串中重复的字符的算法程序：

var s=”abacabefgeeii”

var s1=s.replace(/(.).\*\\1/g,”$1″)

var re=new RegExp(“\[“+s1+”\]”,”g”)

var s2=s.replace(re,””)

alert(s1+s2)  //结果为：abcefgi

思路是使用后向引用取出包括重复的字符，再以重复的字符建立第二个表达式，取到不重复的字符，两者串连。这个方

法对于字符顺序有要求的字符串可能不适用。

//得用正则表达式从URL地址中提取文件名的javascript程序，如下结果为page1

s=””

s=s.replace(/(.\*\\/)\{0,\}(\[^\\.\]+).\*/ig,”$2″)

alert(s)

/利用正则表达式限制网页表单里的文本框输入内容：

用正则表达式限制只能输入中文：οnkeyup=”value=value.replace(/\[^\\u4E00-\\u9FA5\]/g,”)”

onbeforepaste=”clipboardData.setData(‘text’,clipboardData.getData(‘text’).replace(/\[^\\u4E00-\\u9FA5\]/g,”)

)”

用正则表达式限制只能输入全角字符：οnkeyup=”value=value.replace(/\[^\\uFF00-\\uFFFF\]/g,”)”

onbeforepaste=”clipboardData.setData(‘text’,clipboardData.getData(‘text’).replace(/\[^\\uFF00-\\uFFFF\]/g,”)

)”

用正则表达式限制只能输入数字：οnkeyup=”value=value.replace(/\[^\\d\]/g,”)

“onbeforepaste=”clipboardData.setData(‘text’,clipboardData.getData(‘text’).replace(/\[^\\d\]/g,”))”

用正则表达式限制只能输入数字和英文：οnkeyup=”value=value.replace(/\[\\W\]/g,”)

“onbeforepaste=”clipboardData.setData(‘text’,clipboardData.getData(‘text’).replace(/\[^\\d\]/g,”))”

## 171.设置和使用cookie ##

<HTML>

<BODY>

设置与读取 cookies…<BR>

写入cookie的值<input type=textname=gg>

</BODY>

function Set()

var Then = new Date()

Then.setTime(Then.getTime() + 60\*1000 ) //60秒

document.cookie = “Cookie1=”+gg.value+”;expires=”+Then.toGMTString()

function Get()

var cookieString = new String(document.cookie)

var cookieHeader = “Cookie1=”

var beginPosition = cookieString.indexOf(cookieHeader)

if (beginPosition != -1)

document.all.Textbox.value = cookieString.substring(beginPosition + cookieHeader.length)

else

document.all.Textbox.value = “Cookie 未找到!”

</SCRIPT>

</HTML>//

## 172.取月的最后一天 ##

function getLastDay(year,month)

//取年

var new\_year = year;

//取到下一个月的第一天,注意这里传入的month是从1～12

var new\_month = month++;

//如果当前是12月，则转至下一年

if(month>12)

new\_month -=12;

new\_year++;

var new\_date = new Date(new\_year,new\_month,1);

return (new Date(new\_date.getTime()-1000\*60\*60\*24)).getDate();

## 173.判断当前的焦点是组中的哪一个 ##

for(var i=0;i<3;i++)

if(event.srcElement==bb\[i\])

break;//

## 174.实现类 ##

package com.baosight.view.utils;

import javax.servlet.http.HttpSession;

public class Mytag extends TagSupport

public int doStartTag() throws javax.servlet.jsp.JspException

boolean canAccess = false;

HttpSession session= pageContext.getSession();

if (canAccess)

return EVAL\_BODY\_INCLUDE;

return this.SKIP\_BODY;

## 175.在web.xml中添加定义 ##

<taglib-uri>guoguo</taglib-uri>

<taglib-location>/WEB-INF/abc.tld</taglib-location>

</taglib>

## 176.标签库中定义abc.tld ##

< xml version=”1.0″ encoding=”UTF-8″ >

<!DOCTYPE taglib PUBLIC “-//Sun Microsystems, Inc.//DTD JSP Tag Library1.1//EN”

“;>

<uri>guoguo</uri>

<info>Extra 3 Tag Library</info>

<tag>

<name>mytag</name>

<tagclass>com.baosight.view.utils.Mytag</tagclass>

</attribute>

</tag>

</taglib>

## 177.在使用自定义标签的页面中加入自己定义的标签， ##

<%@ taglib uri=”guoguo” prefix=”guoguo” %>

//自己定义标签

## 178.显示带边框的集 ##

dfdfdf

## 179.菜单中的命令的实现 ##
