为什么Extjs grid表格里只有一条数据 - Web 开发 / Ajax
新手提问，Ext.onReady(function(){
//Ext.MessageBox.alert('弹窗','我是一个Div');
//创建表格的列信息
var cm = new Ext.grid.ColumnModel([
{header:'编号',dataIndex:'id'},
{header:'姓名',dataIndex:'name'},
{header:'性别',dataIndex:'sex'},
{header:'描述',dataIndex:'descn'}
]);
var data = [
['1','张三','男','描述一'],
['2','李四','女','描述二'],
['3','王五','男','描述三'],
['4','赵六','女','描述四'],
['5','小七','男','描述五'],
];
var store = new Ext.data.Store({
proxy: new Ext.data.MemoryProxy(data),
reader: new Ext.data.ArrayReader({},[
{name:'id'},
{name:'name'},
{name:'sex'},
{name:'descn'}
])
});
store.load();
var grid = new Ext.grid.GridPanel({
renderTo:'div',
striptRows:true,
store:store,
title:'表格测试',
cm:cm
});
})
[解决办法]
1 grid加配置项 autoHeight:true,
2 data 最后一项不要加逗号

reader 里设置一个参数 id : 'id'
