js技巧收集

1.文本框焦点问题

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="abc" onfocus="if(value=='abc') {value=''}" onblur="if(value=='') {value='abc}">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="abc" 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="变化" name="B1" onMouseOut=this.style.color="blue"

onMouseOver=this.style.color="red"  class="button">

4.平面按钮

<input type=submit value=欢迎订阅 style="border:1px solid :#666666; height:17px; width:50pt; 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>

&nbsp;&nbsp;&nbsp;&nbsp;<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

       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">

140.注意不能通过与 undefined 做比较来测试一个变量是否存在,虽然可以检查它的类型是否为“undefined”。在以

下的代码范例中,假设程序员想测试是否已经声明变量 x :

// 这种方法不起作用

if (x == undefined)

    // 作某些操作

// 字符串 "undefined"

if (typeof(x) == undefined)

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:javascrīpt中没有像vbscrīpt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Javascrīpt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javascrīpt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: ōnkeyup="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

174.实现类

package com.baosight.view.utils;

import javax.servlet.jsp.tagext.TagSupport;

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;

    }

    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>

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 Library 1.1//EN"

"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">
