我向servlet发出一个ajax请求,返回数据库查询的结果。 我可以看到firebug的响应,我想把这些结果放在我已经创建的列表(或其他..)中。
我试着阅读this post,但它对我没有帮助..
代码:
这是ajax请求:
Ext.Ajax.request({
url: '/VIProject/Container',
success: function (action){alert('Lista caricata!'); console.debug(action); },
failure: function (){alert('Errore nel caricamento...');},
headers: {
'my-header': 'foo'
},
params: { action: "GETCONTAINERLIST" }
});
来自servlet(firebug)的响应:
{"message":"OK","container":[{"idOrdine":"1","numLotto":"123"},{"idOrdine":"2","numLotto":"321"},{"idOrdine":"3","numLotto":"876"}],"success":true}
列表:
var listView = Ext.create('Ext.grid.Panel', {
width:425,
height:250,
id: 'lista',
collapsible:true,
title:'Simple ListView <i>(0 items selected)</i>',
store: //???
multiSelect: true,
viewConfig: {
emptyText: 'No images to display'
},
columns: [{
text: 'idOrdine',
flex: 15,
sortable: true,
dataIndex: 'idOrdine'
},{
text: 'Last Modified',
flex: 20,
sortable: true,
dataIndex: 'numLotto'
}]
});
我该怎么办?

我已修改您的代码以使用商店:
Ext.define('MyModel', {
extend: 'Ext.data.Model',
fields: ['idOrdine', 'numLotto']
})
var listView = Ext.create('Ext.grid.Panel', {
width:425,
height:250,
id: 'lista',
collapsible:true,
title:'Simple ListView <i>(0 items selected)</i>',
store: store: {
model: MyModel,
autoLoad: true,
proxy: {
type: 'ajax',
url: '/VIProject/Container',
reader: {
type: 'json',
root: 'container'
}
}
},
multiSelect: true,
viewConfig: {
emptyText: 'No images to display'
},
columns: [{
text: 'idOrdine',
flex: 15,
sortable: true,
dataIndex: 'idOrdine'
},{
text: 'Last Modified',
flex: 20,
sortable: true,
dataIndex: 'numLotto'
}]
});

即便以这种方式运作:
var proxy=new Ext.data.HttpProxy({url:'/VIProject/Container'});
var reader=new Ext.data.JsonReader({},[
{name: 'idOrdine', mapping: 'idOrdine'},
{name: 'numLotto', mapping: 'numLotto'}
]);
var store=new Ext.data.Store( {
proxy:proxy,
reader:reader
});
store.load();
我试着各方面......但我不知道该怎么办!
