@see 获得表单里的数据(不光是表单，任何元素都可以)
@param id 表单的ID
@param type 要返回的类型: string返回用&拼接的字符串, object返回一个js对象, json表示返回json格式的字符串
@return 根据type而定，默认为string

有两种方法，一种是$ajax(option)方法，一种是$getJSON()方法。
实例：
一、数据集所在jsp页面outjsp,代码如下
<%@page contentType="text/plain; charset=UTF-8"
language="java"
import="javaio,javanet,javautil"
buffer="8kb"
session="false"
autoFlush="true"
%>
<%
String jsonData="{data:[{id:200901,name:'name1'},{id:200902,name:'name2'},{id:200903,name:'姓名3'},{id:200904,name:'姓名4'},{id:200905,name:'姓名5'}]}";
//outclear();
outwrite(jsonData);
%>
二、js处理页面
(1)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 10 Transitional//EN" ">
比如jsp页面中有如下数组：<br><input type="hidden" name="docs" id="docs" value='["","普通号","主治医生号","副主任医师号","主任医师号"];' /><br><br>那么在js中可以这么处理：<br>var data = documentgetElementById('docs')value;<br>var dataArr=eval("("+data+")"）；<br>for(var i=0;i<dataArrlength;i++){<br> alert(dataArr[i]create_Time);<br>}
