sencha touch-如何在面板的initcomponent中读取多个json对象（ajax响应）

需要读取从ajax请求获取的多个json对象。我使用了下面给出的代码。时间太长了。因此，其他代码在该代码之前执行

var allVisitStore =  new Ext.data.Store({ 
model: 'allVisit',
autoLoad : true,
proxy: {
    type: 'ajax',
    id: 'allvisit_app_localstore',
    url: '/RadMobApp/api',
    extraParams:{          
        action:'test',
        queryName:'GET_ALL_TEST',
        username:'1234',
        password:'1234',
        retFormat:'XML',
        patTicketId: '4098'
        keyValuePair:'yes'
    },
    // the return will be XML, so lets set up a reader
    reader: new Ext.data.XmlReader({
        // records will have an "T4" tag
        record: 'data'
    })
}

}))

对于上述所有Sencha Touch中的Ajax请求，以及ExtJS都是异步的，是否有任何替代方法。 当商店装载时，你需要做任何你需要做的事情

侦听存储“加载”事件，然后继续处理

您可以在存储配置中添加侦听器，如下所示：

var allVisitStore =  new Ext.data.Store({ 
model: 'allVisit',
autoLoad : true,
proxy: {
    type: 'ajax',
    id: 'allvisit_app_localstore',
    url: '/RadMobApp/api',
    extraParams:{          
        action:'query',
        queryName:'GET_ALL_VISIT',
        username:'superuser',
        password:'superuser',
        retFormat:'XML',
        patTicketId: 'PAT-4098'
        keyValuePair:'yes'
    },
    // the return will be XML, so lets set up a reader
    reader: new Ext.data.XmlReader({
        // records will have an "T4" tag
        record: 'data'
    }),
    listeners : {
        'load' : function(){

            // call code here that should be run when the data has returned

        }
    }
}

allVisitStore.on('load',function(){
// call code here that should be run when the data has returned

或者像这样：

var allVisitStore =  new Ext.data.Store({ 
model: 'allVisit',
autoLoad : true,
proxy: {
    type: 'ajax',
    id: 'allvisit_app_localstore',
    url: '/RadMobApp/api',
    extraParams:{          
        action:'query',
        queryName:'GET_ALL_VISIT',
        username:'superuser',
        password:'superuser',
        retFormat:'XML',
        patTicketId: 'PAT-4098'
        keyValuePair:'yes'
    },
    // the return will be XML, so lets set up a reader
    reader: new Ext.data.XmlReader({
        // records will have an "T4" tag
        record: 'data'
    }),
    listeners : {
        'load' : function(){

            // call code here that should be run when the data has returned

        }
    }
}

allVisitStore.on('load',function(){
// call code here that should be run when the data has returned

---

}))

谢谢你的回复，我已经这样使用了，但没有任何结果，它不存储任何值。还有别的办法吗
