我正在使用Extjs 4.1,試圖爲Combobox加載數據,但不起作用。我對hte json reader root/record有強烈的懷疑。Extjs 4 Combobox數據存儲不能顯示數據
數據模型和存儲的定義,
Ext.define('tagModel', {
extend: 'Ext.data.Model',
fields: [
{name: 'id', type: 'string'},
{name: 'name', type: 'string'}
]
});
var tagStore = new Ext.data.Store({
model: 'tagModel',
proxy: {
type: 'ajax',
url: '/ExtjsWebApp/webresources/question/loadTags',
reader: {
type: 'json',
record : 'rtnList'
}
},
listeners: {
load: function(store, records, options){
alert("success " +records.length);
}
},
autoLoad: true
});
組合框的定義是這個,
{
itemId: 'search_tag_fld',
fieldLabel: 'Tag',
xtype: 'combobox',
displayField: 'name',
valueField: 'id',
store: tagStore,
queryMode: 'remote',
multiSelect: true,
anchor: '100%',
labelHeight: 300
}
我敢肯定,RESTful Web服務將返回數據,因爲這
{"rtnList":[{"id":1,"name":"Java","active":"true"},{"id":2,"name":"J2EE","active":"true"},{"id":3,"name":"JMS","active":"true"},{"id":4,"name":"Design","active":"true"},{"id":5,"name":"SOA","active":"true"}],"successMsg":"success","errorMsg":"","time":"09/21/2013 18:34:55","sessionId":null,"userId":null}
謝謝。那麼如何檢索'successMsg'的值? – user595234
連接到商店代理的讀者將具有存儲在名爲「rawData」的配置中的完整響應。你可以像這樣訪問它:store.getProxy()。getReader()。rawData – existdissolve
