JqueryEasyUI datagrid通过struts请求从后台读取数据

浏览数：27 / 时间：2015年06月09日

我就说下需要注意的事项，希望能帮助到大家：

1.后台返回的格式必须是JqueryEasyUI那种格式。比如：{"total":2,"rows":[{...}]"}这种形式。

2.struts配置文件无须配置result,直接简单配置就行，如下：

</action>

3.action中方法这么写,直接返回success：

result = userService.findPageUserList(this.getPage(), this.getLimit(), user);

//{total=2, rows=[com.duosen.ocs.system.domain.User@151685f, com.duosen.ocs.system.domain.User@19b60bb]}

JSONObject object = JSONObject.fromObject(result);

HttpServletResponse response = ServletActionContext.getResponse();

response.setContentType("html/text;charset=UTF-8");

response.getWriter().write(object.toString());

return null;

这样前台返回数据格式为：

附上用户管理jsp代码：
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ include file="/common/include.jsp"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<body>
<h2>CRUD DataGrid</h2>
<p>Double click the row to begin editing.</p>
<table id="dg" title="My Users" style="width:700px;height:250px"
toolbar="#toolbar" pagination="true" idField="id"
rownumbers="true" fitColumns="true" singleSelect="true">

<script type="text/javascript">
$(function(){
   $(‘#dg‘).edatagrid({
       url: window.BIZCTX_PATH + ‘/system/userjson/userList.action‘,
       saveUrl: ‘save_user.php‘,
       updateUrl: ‘update_user.php‘,
       destroyUrl: ‘destroy_user.php‘
   });
});
</script>
</body>
</html>

include.jsp的代码：
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ page isELIgnored="false" %>
<%@ page import="com.duosen.ocs.constant.WebConstants" %>
<%@ page import="com.duosen.ocs.system.domain.User" %>

<%
   String path = request.getContextPath();
   String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>

<script type="text/javascript">
        window.BIZCTX_PATH = "<%=path%>";
       var bizctxpath = "<%=path%>";
</script>

    <link rel="stylesheet" type="text/css" href="<%=path%>/easyui/themes/default/easyui.css">

以上js都是jqueryEasyUi官方下载。
