Model没有数据格式？
Ext.onReady(function () {
Ext.define('Task', {
extend: "Ext.data.Model",
fields: [{
name: "USER_CODE",
type: "string"
}, {
name: "UESR_NAME",
type: "string"
}, {
name: "USER_CLASS_NAME",
type: "string"
}, {
name: "FLAG_INVALID",
type: "string"
}],
proxy: new Ext.data.HttpProxy({
type: 'get',
url: '/api/Main/Getdtgo/',
reader: {
type: 'json',
root: 'json'
}
})
});
Ext.create("Ext.data.Store", {
model: 'Task',
storeId: 's_user',
autoLoad: true
});
var grid = Ext.create("Ext.grid.Panel", {
title: '<font size=3>用户信息</font>',
frame: true,
width: 600,
height: 280,
columns: [
{ text: "用户编码", dataIndex: 'USER_CODE', width: 100 },
{ text: "姓名", dataIndex: 'UESR_NAME', width: 100 },
{ text: "权限", dataIndex: 'USER_CLASS_NAME', width: 100 },
{ text: "是否作废", dataIndex: 'FLAG_INVALID', width: 100 }],
store: Ext.data.StoreManager.lookup('s_user'),
renderTo: 'grid',
model: 'Task',

});
})
你可以比照这个适当修改，我这个是后台返回JSON的，你的URL什么的自己写，应该没问题吧
