我无法解析我的嵌套 json 数据,我尝试了很多方法,但我无法成功。任何帮助表示赞赏。这是我的 json 输出如下所示:
[
{
"task": {
"locator": "FGWESD",
"subtask": [
{
"work": {
"number": "1145",
"id": "0",
"status": true,
"gate": "N\/A",
},
"sequenceNumber": "0",
"id": "0"
},
{
"work": {
"number": "1145",
"id": "0",
"status": true,
"gate": "N\/A",
},
"sequenceNumber": "0",
"id": "0"
}
],
"connectTime": "0",
"id": "0"
}
}
]
这是我的模型:
Ext.define('MyApp.model.MyModel',{
extend:'Ext.data.Model',
xtype:'myModel',
config:{
fields:[
{name:'number',mapping:'work.number'},
{name:'id',mapping:'work.id'},
{name:'locator',mapping:'task.locator'},
{name:'gate',mapping:'work.gate'}
]
}
});
这里是商店:
Ext.define('MyApp.store.StoreList', {
extend:'Ext.data.Store',
config:{
model:'MyApp.model.MyModel',
storeId: 'id_Store',
// added the url dynamically inside the controller
proxy:{
type:'ajax',
reader:
{
type:"json",
rootProperty: 'subtask'
},
method: 'POST',
actionMethods: {
create : 'POST',
read : 'POST', // by default GET
update : 'POST',
destroy: 'POST'
},
headers :{
"Content-Type" :'application/xml',
'Accept':'application/json'
}
}
}
});
这是我的控制器代码:
Ext.define('MyApp.controller.LoginController', {
extend: 'Ext.app.Controller',
requires: ['Ext.data.proxy.Rest'],
config: {
// My code is too long to add here so am adding store loading when user taps login button
},
getDetails: function(){
var segmentStore = Ext.create('MyApp.store.StoreList');
var url = 'http://localhost:8080/apps';
segmentStore.getProxy().setUrl(url.trim());
segmentStore.load({
scope:this,
callback: function(records, operation, success){
if(success){
console.log('records: ',records);
console.log('records: '+records.length); // prints here 1
console.log('locator: '+records[0].getData().locator);
// prints FGWESD
console.log('locator: '+records[0].getData().number);
//prints undefined
//
}
}
}
)
},
});
任何人都可以帮助我。如何获取数字、门、ID 和状态的值?必须对模型、存储和控制器进行哪些必要的更改?请帮我解决?谢谢。
