我的阅读器功能是
Ext.define('MyReader', {
extend: 'Ext.data.reader.Json',
alias: 'reader.my-json',
read: function(object) {
object.workXml = Ext.decode(object.responseText);
return this.callParent([object]);
}
});
我的商店是
Ext.define('WR.store.WorkRecord', {
extend : 'Ext.data.Store',
model : 'WR.model.WorkRecord',
autoLoad: true,
proxy: {
type: 'jsonp',
api: {
read: 'http://192.168.90.188:8282/service/work/json/getWorkXmlByCompositeKey?compositeKey=455778-OLIVIA&authToken=123',
update: 'data/updateUsers.json'
},
reader: {
type: 'my-json',
root: 'workXml',
successProperty: 'success'
}
}
});
但是我的阅读器函数返回一个空对象。当我 console.log(object.workXml) 时，它说未定义，当我 console.log(object) 时，它没有任何 resposeText。所以我不知道如何解码响应。是否需要使用回调方法？如果是这样，请帮助如何编写它。实际上我想解码这个 json 字符串并将其映射到我的模型，以便我可以轻松使用它。我的模型是
Ext.define('WR.model.WorkRecord', {
extend: 'Ext.data.Model',
fields: ['name',
{name:'ns1term',mapping:'Work.Titles.Title[0]["ns1:term"]'},
{name:'ns0term',mapping:'Work.Titles.Title[1]["ns0:term"]'},
{name:'agent_display',mapping:'Work.Agents.Display'},
{name:'cultures_display',mapping:'Work.Cultures.Display'},
{name:'locations_display',mapping:'Work.Locations.Display'},
