等价类划分第二弹！

类似于上周的作业，为上周作业“等价类划分”的拓展版本。

改变之处为EditBox变为三个。

一、题目要求

二、划分等价类

三、测试用例

编号	测试用例	预期输出结果
1	123 aBc 456def	输入1，2，3有效
2	aBc 456def	输入1长度小于1
3	123 aBc@ 456def	输入2含非法字符
4	123 aBc 456def7	输入3长度大于6
5	aBc@ 456def	输入1，2错误
6	aBc 456def7	输入1，3错误
7	123 aBc@ 456def7	输入2，3错误
8	aBc@ 456def7	输入1，2，3错误

四、代码

 1 <%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
 2 <%
 3 String path = request.getContextPath();
 4 String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
 5 %>
 6 <%request.setCharacterEncoding("utf-8"); %>
 7 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
 8 <html>
 9 <script type="text/javascript">
10     function func()
11     {
12         var inputArray = new Array(3);
13         var alertStr = new Array("长度小于1,无效","长度大于6，无效","非法字符，无效", "有效");
14         var reg = /^[A-Za-z0-9]+$/;    //正则表达式表示字母或者数字
15         var i;
16         for(i = 0; i<3; i++){
17             var s = document.getElementById(i).value;
18             if(arr=s.match(reg)){
19                 if(s.length > 6) inputArray[i] = 1;
20                 else inputArray[i] = 3;
21             }
22             else{
23                  if(s.length < 1) inputArray[i] = 0;
24                  else inputArray[i] = 2;                     
25             }
26         }
27         
28         tips = "";
29         var j;
30         for(j = 0; j<3; j++){
31             index = inputArray[j];
32             tips += "第"+(j+1)+"个文本框输入"+alertStr[index]+"\n";
33         }
34         alert(tips);
35     }
