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

UTF-8 UTF-8
================================


168.XML操作
<xml id="xmldata" src="/data/books.xml">
<div id="guoguo"></div>
<script>
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

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(){return this.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))
{
return RegExp.$1*Math.pow(255,3))+RegExp.$2*Math.pow(255,2))+RegExp.$3*255+RegExp.$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="http://www.9499.net/page1.htm"
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：onkeyup="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： onkeyup="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：onkeyup="value=value.replace(/[^/d]/g,'')

软件开发网 www.mscto.com

"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：onkeyup="value=value.replace(/[/W]/g,'')

"onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^/d]/g,''))"


171.设置和使用cookie
<HTML>
<BODY>

写入cookie的值<input type=text name=gg>
<INPUT TYPE = BUTTON Value = "设置cookie" onClick = "Set()">
<INPUT TYPE = BUTTON Value = "读取cookie" onClick = "Get()"><BR>
<INPUT TYPE = TEXT NAME = Textbox>
</BODY>
<SCRIPT LANGUAGE="JavaScript">
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;//

HttpSession session= pageContext.getSession();
if (canAccess)
{
return EVAL_BODY_INCLUDE;

else
{
return this.SKIP_BODY;

194.是弹出方法的定义
String.prototype.trim=function()
{
return this.replace(/(^/s*)|(/s*$)/g, "");
}
alert(" ".trim)//


195.防止网页被包含
if (window != window.top)
top.location.href = location.href;//


196.让网页一直在frame里面
if(window==window.top)
{
document.body.innerHTML="<center><h1>请通过正常方式访问本页面！</h1></center>";
//window.close();
}//


197.加为首页
<SCRIPT>
function fnSet(){
oHomePage.setHomePage(location.href);
event.returnValue = false;
}
</SCRIPT>
<IE:HOMEPAGE ID="oHomePage" style="behavior:url(#default#homepage)"/>//

</HTML> //xml数据岛中添加记录


-------------------------------
The following list is a sample of the properties and methods that you use to access nodes in an XML

document.

Property/ Method Description
XMLDocument Returns a reference to the XML Document Object Model (DOM) exposed by the object.

documentElement Returns the document root of the XML document.
childNodes Returns a node list containing the children of a node (if any).
item Accesses individual nodes within the list through an index. Index values are zero-based, so

item(0) returns the first child node.

软件开发网 www.mscto.com

text Returns the text content of the node.

The following code shows an HTML page containing an XML data island. The data island is contained within

the <XML> element.

<HTML>
<HEAD>
<TITLE>HTML with XML Data Island</TITLE>
</HEAD>
<BODY>
<P>Within this document is an XML data island.</P>

<XML ID="resortXML">
<resorts>
<resort code='1'>Adventure Works</resort>
<resort>Alpine Ski House</resort>
</resorts>
</XML>

</BODY>
</HTML>
For an example, you can cut and paste this sample line of code:
resortXML.XMLDocument.documentElement.childNodes.item(1).text//读取页面上的XML数据岛中的数据

resortXML.documentElement.childNodes.item(0).getAttribute("code")//读取页面上的XML数据岛中的数据
resortXML.documentElement.childNodes[0].getAttribute("code")//读取页面上的XML数据岛中的数据

199.模式窗口
父窗口
var url="aaa.jsp";
var

data=showModalDialog(url,null,"dialogHeight:400px;dialogHeight:600px;center:yes;help:No;status:no;resizab

le:Yes;edge:sunken");
if(data)
alert(data.value);

子窗口
var data=new Object();
data.value1="china";
window.returnValue=data;
window.close();


200.动态设置事件，带参数
<INPUT TYPE="text" NAME="a1">
<SCRIPT LANGUAGE="JavaScript">
<!--
function hah(para)
{
alert(para)
}
a1.onclick=function()
{
hah('canshu ')
}
//a1.attachEvent("onclick",function(){hah('参数')});
//-->

</SCRIPT>//


201.将url转化为16进制形式
var ret = '';

for(var i=0; i < str.length; i++)
{
var ch = str.charAt(i);
var code = str.charCodeAt(i);

if(code < 128 && ch != '[' && ch != '/'' && ch != '=')
{
ret += ch;
}
else
{
ret += "[" + code.toString(16) + "]";
}
}
return ret;//


202.打开新的窗口并将新打开的窗口设置为活动窗口
var newWin=window.open("xxxx");
newWin.focus();//


203.容错脚本
JS中遇到脚本错误时不做任何操作:window.onerror = doNothing;
指定错误句柄的语法为:window.onerror = handleError
function handleError(message, URI, line)
{// 提示用户，该页可能不能正确回应
return true; // 这将终止默认信息
}//在页面出错时进行操作

204.JS中的窗口重定向:

window.navigate("http://www.sina.com.cn");//

205.防止链接文字折行
document.body.noWrap=true;//

206.判断字符是否匹配.
string.match(regExpression)//

207.
href="javascript:document.Form.Name.value='test';void(0);"//不能用onClick="javacript:document.Form.Name.v

alue='test';return false;"

当使用inline方式添加事件处理脚本事，有一个被包装成匿名函数的过程，也就是说
onClick="javacript:document.Form.Name.value='test';return false;"被包装成了：
functoin anonymous()
{
document.Form.Name.value='test';return false;
}
做为A的成员函数onclick。
而href="javascript:document.Form.Name.value='test';void(0);"相当于执行全局语句，这时如果使用return语句会

报告在函数外使用return语句的错误。


208.进行页面放大
<P onmouseover="this.style.zoom='200%'" onmouseout="this.style.zoom='normal'">
sdsdsdsdsdsdsdsds
</p>//

209.放置在页面的最右边
<input type="text" value='bu2' style="float:right">//

210.通过style来控制隔行显示不同颜色
<style>
tr{
bgcolor:expression(this.bgColor=((this.rowIndex)%2==0 )? 'white' : 'yellow');
}
</style>
<table id="oTable" width="100" border="1" style="border-collapse:collapse;">
<tr><td>&nbsp;</td></tr>
<tr><td>&nbsp;</td></tr>
<tr><td>&nbsp;</td></tr>
<tr><td>&nbsp;</td></tr>
<tr><td>&nbsp;</td></tr>
</table>//
211.全屏最大化
newwindow=window.open("","","scrollbars")
if (document.all)
{
newwindow.moveTo(0,0)
newwindow.resizeTo(screen.width,screen.height)
}//

212.根据名字解析xml中的节点值

var XMLDoc=new ActiveXObject("MSXML");
XMLDoc.url="d:/abc.xml";
aRoot=XMLDoc.root;
a1.innerText=aRoot.children.item("name").text;//


213.在页面上解析xml的值
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xmlsdk/html/<chmetcnv unitname="C" sourcevalue="5996" hasspace="False" negative="False" numbertype="1" tcsc="0" w:st="on">5996c</chmetcnv>682-3472-4b03-9fb0-1e08

fcccdf35.asp
//

214.看一个字符串里面有多少个回车符，返回值是一个数组
var s=value.match(//n/g);if(s)if(s.length==9){alert('10行了');return false;}//

215.获得asc码
var s='aa';
alert(s.charCodeAt(1))//

216.文字居右对齐
<input type="text" value="123" style="text-align:right">//

217.判断一个方法是否存在
function pageCallback(response){
alert(response);
}
if(pageCallback)
alert(1)//


218.判断一个变量是否定义
if(typeof(a)=="undefined")
{
alert()
}//


219.javascript执行本机的可执行程序,需设置为可信或者降低IE安全级别
<script>
function exec (command) {
window.oldOnError = window.onerror;
window._command = command;
window.onerror = function (err) {
if (err.indexOf('utomation') != -1) {
alert('命令已经被用户禁止！');
return true;
}
else return false;
};
var wsh = new ActiveXObject('WScript.Shell');
if (wsh)
wsh.Run(command);
window.onerror = window.oldOnError;
}
</script>
调用方式
<a href="javascript:" onclick="exec('D:/test.bat')">测试</a>//

220.弹出新页面，关闭旧页面，不弹出提示框
var w=screen.availWidth-10;
var h=screen.availHeight-10;

var swin=window.open("/mc/mc/message_management.jsp",

"BGSMbest","scrollbars=yes,status,location=0,menubar=0,toolbar=0,resizable=no,top=0,left=0,height="+h+",w

idth="+w);
window.opener=null;
window.close();//

221.能输入的下拉框
<span>
<input name="Department1" id="Department1" style=" border-right:0;width:130" autocomplete="off">
<span style="width:150;overflow:hidden">
<select style="width:150;margin-left:-130" onChange="Department1.value=value">
<option value=""></option>
<option value="asdfasfadf">asdfasfadf</option>
<option value="546546">546546</option></select> //


222.在方法中定义全局变量
function globalVar (script) {
eval(script);//all navigators

//window.execScript(script); //for ie only
}
globalVar('window.haha = "../system";');
alert(haha);//在方法中定义全局变量，其中的haha就是全局变量了

223.显示一个对象的全部的属性和属性的值
var a=new Object();
a.name='a1';
a.***='mail'
for(var p in a)
{
alert(p+"="+a[p])
}//


224.16进制转换成10进制
var n = parseInt("2AE",16);//这里将16进制的 2AE 转成 10 进制数，得到 n 的值是 686
225.复制粘贴
<BODY>
<input type="file" name='a1'><input type="button" value='复制粘贴' onclick="haha()"><div id="aa"></div>
<SCRIPT LANGUAGE="JavaScript">
<!--
function haha()
{
clipboardData.setData("Text",a1.value);
aa.innerText=clipboardData.getData("Text");
}
//-->
</SCRIPT>
</BODY>//

226.获得对象类型

switch (object.constructor){
case Date:
...
case Number:
...
case String:
...
case MyObject:
...
default:
...
}//


227.图片加载失败时重新加载图片
<img src="http://www.rdxx.com/Files/Pic/2007-<chsdate year="1955" month="9" day="13" islunardate="False" isrocdate="False" w:st="on">9/13/55</chsdate>HD543AADF43305FC.gif" onerror="this.src="http://www.rdxx.com/Files/Pic/2007-9/13/417HB96E<chmetcnv unitname="C" sourcevalue="5" hasspace="False" negative="False" numbertype="1" tcsc="0" w:st="on">05C</chmetcnv>65605E8.gif"">//

228.
//font_effect.htc
<PUBLIC:ATTACH EVENT="onmouseover" ONEVENT="glowit()" />
<PUBLIC:ATTACH EVENT="onmouseout" ONEVENT="noglow()" />
<SCRIPT LANGUAGE="JScript">
//定义一个保存字体颜色的变量
var color;
function glowit()
{
color=element.style.backgroundColor;
element.style.backgroundColor='white'
}
function noglow() 软件开发网 www.mscto.com
{
element.style.backgroundColor=color
}
</SCRIPT>

//abc.css
tr{behavior:url(font_effect.htc);}

229.可以通过css和htc改变表格的颜色,仅IE支持
//xxx.html
<link rel="stylesheet" type="text/css" href="abc.css">
<TABLE border='1' id="a1">
<TR style="background-color:red">
<TD>1</TD>
<TD>2</TD>
<TD>3</TD>
</TR>
<TR style="background-color:yellow">
<TD>4</TD>
<TD>5</TD>
<TD>6</TD>
</TR>
</TABLE>//

230.在页面上画点
function a(x,y,color)
{
document.write("<img border='0' style='position: absolute; left: "+(x+20)+"; top:

"+(y+20)+";background-color: "+color+"' width=1 height=1>")
}//

231.自动关闭网页
<script LANGUAGE="javascript">
<!--
setTimeout('window.close();', 10000); //60秒后关闭
// -->
</script>
<p align="center">本页10秒后自动关闭,请注意刷新页面</p>
