简单表格
排序,显示某列,读取本地数据
[img]http://files.jb51.net/file_images/article/201304/20130418172819114.png[/img]
//本地数据
var datas = [
['1', 'gao', 'man'], ['2', 'gao', 'man'], ['3', 'gao', 'man']
];
//创建面板
Ext.create('Ext.grid.Panel', {
title: 'easy grid',
width: 400,
height: 300,
renderTo: Ext.getBody(),
frame: true,
viewConfig: {
forceFit: true,
stripRows: true
},
store: {//配置数据代理
fields: ['id', 'name', 'gender'],
proxy: {
type: 'memory',
data: datas,
reader: 'array' //数据读取器为 数据读取
},
autoLoad: true
},
columns: [{ //自定义列信息
header: 'id',
width: 30,
dataIndex: 'id', //绑定fields中得字段
sortable: true
}, {
header: 'name',
width: 80,
dataIndex: 'name',
sortable: true
}, {
header: 'gender',
width: 80,
dataIndex: 'gender',
sortable: true
}
]
})
表格列:
行号, bool行转成是否,日期格式化输出(date,top day), number数据类型格式化输出(change,volume),Action列(操作列)

选择模式:Selection
选择模式分为三类:
1,行选择(默认)
2.单元格选择
3.复选框选择(checkbox组)
演示单元格选择代码:
[img]http://files.jb51.net/file_images/article/201304/20130418172819118.png[/img]
只需在上述代码配置节当中,加入
tbar: [
{
text: '取得所选单元格',
handler: function () {
var cell = grid.getSelectionModel().getCurrentPosition(); //getSelectionModel()获取当前选择模式,getCurrentPosition()获取当前选择的单元格
alert(Ext.JSON.encode(cell));
}
}
],
selType:'cellmodel' //设置 选择模式 为 单元格选择

var row = rows[i];
var myDate = new Date(row.get('date'));
msg.push('选中行的Date列:' + myDate.toLocaleString()); //转换时间格式
}
alert(msg.join('\n'));
}
}

表格汇总 Ext.grid.feature.Summary
[img]http://files.jb51.net/file_images/article/201304/20130418172819121.png[/img]
汇总值计算 根据表格的每一列进行计算,计算方式 有指定的 summaryType决定.默认的有
上图5种.
此例应用 sum和average

把 CellEditing 改成 RowEditing
想要获取修改后的数据,ajax请求服务器,做出响应.
grid.on('edit', onEdit, this); //添加编辑事件,获取数据
function onEdit(e) {
alert(e.record.get('name')); //get()参数是字段名字.
}
[b]gridpanel中的checkbox列 根据数据库值 来初始化是否被选
[/b]
listeners: {
load: function(store) {
var index = 0;
store.each(function(record) {
if(record.data.column_name == '1') { //column_name 替换成你的列名， '1' 替换成你的值
grid.selModel.selectRow(index,true);
}
index++;
})
}
