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

var ExcelSheet;

ExcelApp = new ActiveXObject(“Excel.Application”);

ExcelSheet = new ActiveXObject(“Excel.Sheet”);

//本代码启动创建对象的应用程序(在这种情况下,Microsoft Excel 工作表)。一旦对象被创建,就可以用定义的对

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”);

// 用 Application 对象用 Quit 方法关闭 Excel。

ExcelSheet.Application.Quit();//

150.根据标签获得一组对象

var coll = document.all.tags(“DIV”);

if (coll!=null)

{

for (i=0; i<coll.length; i++)

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;//

174.实现类

package com.baosight.view.utils;

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;

}

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

<attribute>

<name>id2</name>

<required>true</required>

<rtexprvalue>true</rtexprvalue>

</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

<fieldset style=”border:1px gray solid;width:100px”>

</HTML> //xml数据岛中添加记录

——————————-

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>
