ExtJs与JSON格式数据绑定的方法

2010-03-23 14:48 351 查看
在这个AJAX流行年代，xml绑定已经满足不了我们的需求。ExtJs又为我们提供了JSON格式数据绑定的方法，下面我们来看看效果

用到的有二个文件survey.html、xml-grid.html，注意js引用路径。

survey.html文件：

[{"appeId":"1","survId":"1","location":"","surveyDate":"2008-03-14","surveyTime":"12:19:47","inputUserId":"1","inputTime":"2008-03-14 12:21:51","modifyTime":"0000-00-00 00:00:00"},
{"appeId":"2","survId":"32","location":"","surveyDate":"2008-03-14","surveyTime":"22:43:09","inputUserId":"32","inputTime":"2008-03-14 22:43:37","modifyTime":"0000-00-00 00:00:00"},
{"appeId":"3","survId":"32","location":"","surveyDate":"2008-03-15","surveyTime":"07:59:33","inputUserId":"32","inputTime":"2008-03-15 08:00:44","modifyTime":"0000-00-00 00:00:00"},
{"appeId":"4","survId":"1","location":"","surveyDate":"2008-03-15","surveyTime":"10:45:42","inputUserId":"1","inputTime":"2008-03-15 10:46:04","modifyTime":"0000-00-00 00:00:00"},
{"appeId":"5","survId":"32","location":"","surveyDate":"2008-03-16","surveyTime":"08:04:49","inputUserId":"32","inputTime":"2008-03-16 08:05:26","modifyTime":"0000-00-00 00:00:00"},
{"appeId":"6","survId":"32","location":"","surveyDate":"2008-03-20","surveyTime":"20:19:01","inputUserId":"32","inputTime":"2008-03-20 20:19:32","modifyTime":"0000-00-00 00:00:00"}]

json-grid.html 文件：

<html>
<head>

Ext.onReady(function(){

var proxy=new Ext.data.HttpProxy( {url:'survey.html'});
//定义reader
var reader=new Ext.data.JsonReader(
{
},[
{name: 'appeId', mapping: 'appeId'},
{name: 'survId'},
{name: 'location'},
{name: 'surveyDate'},
{name: 'surveyTime'},
{name: 'inputUserId'}
]
)
//构建Store
var store=new Ext.data.Store( {
proxy:proxy,
reader:reader
});
//载入
store.load();

// create the grid
var grid = new Ext.grid.GridPanel({
store: store,
columns: [
{header: "appeId", width: 60, dataIndex: 'appeId', sortable: true},
{header: "survId", width: 60, dataIndex: 'survId', sortable: true},
{header: "location", width: 60, dataIndex: 'location', sortable: true},
{header: "surveyDate", width: 100, dataIndex: 'surveyDate', sortable: true},
{header: "surveyTime", width: 100, dataIndex: 'surveyTime', sortable: true},
{header: "inputUserId", width:80, dataIndex: 'inputUserId', sortable: true}
],
renderTo:'example-grid',
width:540,
height:200
});

});
