dojo.require("dojo.data.ItemFileWriteStore");
dojo.require("dojox.layout.FloatingPane");

dojo.require("dijit.dijit");
dojo.require("dojox.grid.DataGrid");
//数据对象中显示的结果必须是对象中的items属性中对应的值,否则显示不出来

var structure = [

第二种:数据来源于server端,和server进行交互 

 

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<script type="text/javascript">

dojo.require("dojo.parser");
dojo.require("dijit.form.Button"); 
dojo.require("dojox.grid.DataGrid");
dojo.require("dojo.data.ItemFileWriteStore");
dojo.require("dojo.data.ItemFileWriteStore");
dojo.require("dojox.layout.FloatingPane");

dojo.require("dijit.dijit");
dojo.require("dojox.grid.DataGrid");


</script>
</head>
<body class="claro">


<div class="heading">dojox.grid.DataGrid Basic Test</div>
<!-- 类似于发送了一个ajax请求获取数据,存储在ItemFileWriteStore对象中  -->
<span dojoType="dojo.data.ItemFileWriteStore" 
	jsId="jsonStore" url="../WriteJson">
</span>

<table dojoType="dojox.grid.DataGrid"
	jsid="grid" id="grid" 
	store="jsonStore" query="{ name: '*' }" rowsPerPage="1" rowSelector="20px">
	<thead>
		<tr>
			<th field="name" width="300px">Country/Continent Name</th>
			<th field="type" width="auto">Type</th>
		</tr>
	</thead>
</table>

</body>
</html>

 

server端的代码

package hb.servlet;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Servlet implementation class WriteJson
 */
public class WriteJson extends HttpServlet {
	private static final long serialVersionUID = 1L;
       
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		this.doPost(request, response);
	}

	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		System.out.println("{items:[{name:'Africa', type:'continent'},{name:'Africa1', type:'continent1'}]}");
		PrintWriter pw = response.getWriter();
		pw.write("{items:[{name:'Africa', type:'continent'},{name:'Africa1', type:'continent1'},{name:'Africa1', type:'continent1'},{name:'Africa1', type:'continent1'},{name:'Africa1', type:'continent1'}]}");
		pw.flush();
		pw.close();
	}

}

 

备注:server端输出的字符串必须也要按照json对象中包含items属性的这中格式,否则是无法在前端显示内容的。
