象变量在代码中引用它。 在下面的例子中,通过对象变量 ExcelSheet访问新对象的属性和方法和其他 Excel 对象,
包括 Application 对象和 ActiveSheet.Cells 集合。
// 使 Excel 通过 Application 对象可见。
ExcelSheet.Application.Visible = true;
// 将一些文本放置到表格的第一格中。
ExcelSheet.ActiveSheet.Cells(1,1).Value = “This is column A, row 1”;
// 保存表格。
ExcelSheet.SaveAs(“C:\\TEST.XLS”);

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
<xml id=”xmldata” src=”/data/books.xml”>
<div id=”guoguo”amp;>amp;amp;>amp;lt;/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
{
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∗Math.pow(255,3))+RegExp.2*Math.pow(255,2))+RegExp.3∗255+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=””
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,”)
“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>
设置与读取 cookies…<BR>
写入cookie的值<input type=textname=gg>
<INPUT TYPE = BUTTON Value = “设置cookie”onClick = “Set()”>
<INPUT TYPE = BUTTON Value = “读取cookie”onClick = “Get()”amp;>amp;amp;>amp;lt;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;//

boolean canAccess = false;
HttpSession session= pageContext.getSession();
if (canAccess)
{
return EVAL_BODY_INCLUDE;
}
else
{
return this.SKIP_BODY;

}
175.在web.xml中添加定义
<taglib>
<taglib-uri>guoguo</taglib-uri>
<taglib-location>/WEB-INF/abc.tld</taglib-location>
</taglib>
176.标签库中定义abc.tld

//自己定义标签
178.显示带边框的集
<fieldset style=”border:1px gray solid;width:100px”>

——————————-
The following list is a sample of the properties and methods that youuse to access nodes in an XML
document.
Property/ Method Description
XMLDocument Returns a reference to the XML Document Object Model (DOM) exposedby the object.
documentElement Returns thedocument root of the XML document.
childNodes Returns a node list containing the children of anode (if any).
item Accesses individual nodes within the list throughan index. Index values are zero-based, so
item(0) returns the first childnode.
text Returns the text content of the node.
The following code shows an HTMLpage 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 dataisland.</P>
<XMLID=”resortXML”>
<resorts>
<resort code=’1′>AdventureWorks</resort>
<resort>Alpine SkiHouse</resort>
</resorts>
</XML>
</BODY>
</HTML>
For an example, you can cut and paste this sample line of code:
resortXML.XMLDocument.documentElemenem(1).text//读取页面上的XML数据岛中的数据
resortXML.documentElemenem(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(“;);//
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;”>
<tramp;>amp;amp;>amp;lt;tdamp;>amp;amp;>amp;amp;nbsp;</tdamp;>amp;amp;>amp;lt;/tr>
<tramp;>amp;amp;>amp;lt;tdamp;>amp;amp;>amp;amp;nbsp;</tdamp;>amp;amp;>amp;lt;/tr>
<tramp;>amp;amp;>amp;lt;tdamp;>amp;amp;>amp;amp;nbsp;</tdamp;>amp;amp;>amp;lt;/tr>
<tramp;>amp;amp;>amp;lt;tdamp;>amp;amp;>amp;amp;nbsp;</tdamp;>amp;amp;>amp;lt;/tr>
<tramp;>amp;amp;>amp;lt;tdamp;>amp;amp;>amp;amp;nbsp;</tdamp;>amp;amp;>amp;lt;/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=aRooem(“name”).text;//
213.在页面上解析xml的值
url=/library/en-us/xmlsdk/html/5996c682-3472-4b03-9fb0-1e08
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(“/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=””amp;>amp;amp;>amp;lt;/option>
<option value=”asdfasfadf”>asdfasfadf</option>
<option value=”546546″>546546</optionamp;>amp;amp;>amp;lt;/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’amp;>amp;amp;>amp;lt;input type=”button”value=’复制粘贴’ onclick=”haha()”amp;>amp;amp;>amp;lt;divid=”aa”amp;>amp;amp;>amp;lt;/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=”/aa.gif” onerror=”this.src=’/aa.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()
{
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=1amp;>amp;amp;>amp;quot;)
}//
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>
