我正在使用Extjs 4.1,试图为Combobox加载数据,但不起作用。我对hte json reader root/record有强烈的怀疑。Extjs 4 Combobox数据存储不能显示数据
数据模型和存储的定义,
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
});
组合框的定义是这个,
{
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服务将返回数据,因为这
{"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}
谢谢。那么如何检索'successMsg'的值? – user595234
连接到商店代理的读者将具有存储在名为“rawData”的配置中的完整响应。你可以像这样访问它:store.getProxy()。getReader()。rawData – existdissolve
