我试图商店映射

在JSON值，我需要@name，要显示的干扰和信息栏。我尝试了映射函数，但它的效果很好，还有其他想法吗？

请解释你如何使用这些数据。它在模型中吗？在一家商店？在自定义请求中？ – jprofitt

我已为3个字段定义了一个模型，并且还添加了映射。商店将从服务中加载数据，模型将相应地使用它。我将在网格中显示 – Sads

这有帮助吗？如果您不使用JSONReader，看起来像映射属性有问题。

你可以写你自己的商店:: SetData方法映射财产以后这样

Ext.define('App.store.DemoStore', { 
extend: 'Ext.data.Store', 

config: { 
    model: 'App.model.DemoModel', 
    storeId: 'Demo', 
    autoLoad: true, 
    autoSync: true, 
    proxy: { 
     type: 'localstorage', 
     id: 'demo-data' 
    } 
}, 

setData: function (data) { 
    var mappingObj = {}, 
     newData = []; 

    // get mappings from model 
    Ext.each(this.getModel().getFields().all, function (singleField) { 
     // name and mapping of the field 
     var name =  singleField._name, 
      mapping = singleField._mapping; 

     if (mapping){ 
      mappingObj[name] = mapping; 
     } 
    }); 

    Ext.each(data, function (singleData) { 
     // main mapping 
     Ext.Object.each(mappingObj, function(item){ 
      singleData[item] = singleData[mappingObj[item]]; 
      delete singleData[mappingObj[item]]; 
     }); 

     newData.push(singleData); 
    }); 

    // start the original setData(data) 
    this.callParent(newData); 
}

}）;
