（Ext）从后台查询出的Json格式数据在Ext前端不能显示

Question

刚接触Ext不久，现要用Ext Grid的分页，但是从后台取出的Json数据在js里就是不显示。帮忙看下

我的这个账号是刚注册的 没多少分了 都压上了

代码如下：

js代码：

var cm_sub_user = new Ext.grid.ColumnModel([new Ext.grid.RowNumberer(), {
header : '手机号码',
width : 150,
dataIndex : 'mobile',
sortable : true
},{
header : '机主名',
width : 100,
dataIndex : 'owner',
sortable : true
}, {
header : '城市编号',
width : 100,
dataIndex : 'city_code',
sortable : true
}, {
header : '软件版本号',
width : 100,
dataIndex : 'ver',
sortable : true
}, {
header : '服务地址',
width : 200,
dataIndex : 'svc1',
sortable : true
}, {
header : '创建日期',
id : 'create_date',
dataIndex : 'create_date',
renderer : Ext.util.Format.dateRenderer('m/d/Y H:i:s'),
sortable : true
}]);

cm_sub_user.defaultSortable = true;

var text_search_company = new Ext.form.TextField({
name : 'pageData.userMobile',
width : 200,
emptyText : '请输入手机号码查询!',
listeners : {
'specialkey' : function(field, e) {
if (e.getKey() == Ext.EventObject.ENTER) {
searchCompany();
}
}
}
});

// grid的查找方法
var searchCompany = function() {
ds_sub_user.load({params : {start : 0, limit : 20}});
};

var btn_search_company = new Ext.Button({
text : '查询',
iconCls : 'icon-search',
handler : searchCompany
});

var ds_sub_user = new Ext.data.Store({
proxy : new Ext.data.HttpProxy({
url : 'UserManageAction_findSubUserByPageCondition.action'
}),
reader : new Ext.data.JsonReader({
totalProperty : 'totalProperty',
root : 'jsonOperatorList'
}, [{
name : 'mobile',
type : 'string'
}, {
name : 'owner',
type : 'string'
}, {
name : 'city_code',
type : 'string'
}, {
name : 'ver',
type : 'string'
}, {
name : 'svc1',
type : 'string'
}, {
name : 'create_date',
type : 'date',

dateFormat : 'Y-m-d H:i:s'
}])
});

var grid_sub_user = new Ext.grid.EditorGridPanel({
title : '终端用户管理',
iconCls : 'icon-grid',
loadMask : {msg : '数据加载中...'},
region : 'center',
cm : cm_sub_user,
ds : ds_sub_user,
sm : new Ext.grid.RowSelectionModel({singleSelect : true}),
enableColumnMove : false,
trackMouseOver : false,
frame : true,
autoExpandColumn : 'create_date',
clicksToEdit : 1,
tbar : [text_search_company, btn_search_company],
bbar : new Ext.PagingToolbar({
pageSize : 20,
store : ds_sub_user,
displayInfo : true,
displayMsg : '第 {0} - {1} 条 共 {2} 条',
emptyMsg : "没有记录"
})
});

具体后台Json的格式是什么样子的？

我后台的json格式是这样的：

{totalProperty=2, jsonOperatorList=[{"mobile":"15094304697","password":"123456","owner":"服务器","city_code":"025","ver":"3.0","svc1":"www.baidu.com","svc2":null,"plat_md5":"12","plat_no":"15852020123","call_no1":"15852320458","call_no2":null,"call_no3":null,"call_no4":null,"shd_md5":"12","shd_conf_status":"1","all_md5":"123456","create_date":"2010-08-16 00:00:00","rn":1},{"mobile":"15852324369","password":"100000","owner":"交换机","city_code":"025","ver":"0.8","svc1":"www.google.cn","svc2":null,"plat_md5":"12","plat_no":"15094320157","call_no1":"15623015483","call_no2":null,"call_no3":null,"call_no4":null,"shd_md5":"34","shd_conf_status":"2","all_md5":"158231","create_date":"2010-08-16 00:00:00","rn":2}]}

Answer 1

你的json字符串有问题。你这里都是totalProperty=2, jsonOperatorList=。。“=”号。这是不行的。。
你应该是这样
[code="js"]
{"totalProperty":2, "jsonOperatorList":[{"mobile":"15094304697","password":"123456","owner":"服务器","city_code":"025","ver":"3.0","svc1":"www.baidu.com","svc2":null,"plat_md5":"12","plat_no":"15852020123","call_no1":"15852320458","call_no2":null,"call_no3":null,"call_no4":null,"shd_md5":"12","shd_conf_status":"1","all_md5":"123456","create_date":"2010-08-16 00:00:00","rn":1},{"mobile":"15852324369","password":"100000","owner":"交换机","city_code":"025","ver":"0.8","svc1":"www.google.cn","svc2":null,"plat_md5":"12","plat_no":"15094320157","call_no1":"15623015483","call_no2":null,"call_no3":null,"call_no4":null,"shd_md5":"34","shd_conf_status":"2","all_md5":"158231","create_date":"2010-08-16 00:00:00","rn":2}]}
