Question

我无法分辨为什么我的商店不会绑定从服务器返回的数据。提前谢谢。

以下是我实例化并调用“load”的方法：

var store = Ext.create('Iip.store.giip.other.States');
store.load({
    params: {c: 'get_states'},
    scope: this,
    callback: function(records, operation, success) {
        console.log(records); **<=== never prints**
    }
});

这是商店：

Ext.define("Iip.store.giip.other.States", {
    extend: "Ext.data.Store",
    storeId:"states-store",
    model: "Iip.model.giip.other.State",
    autoLoad: false,
    buffered: true
});

以下是模型：

Ext.define('Iip.model.giip.other.State', {
    extend: 'Ext.data.Model',
    idProperty: "stateId",

    fields:[
        {name: "stateId", type: "int"},
        {name: "state", type: "string"}
    ],

    proxy: {
        type: "ajax",
        actionMethods: {
            read: "POST"
        },
        api: {
            read: "indexes/common_index.php"
        },
        reader: {
            type: "json",
            root: "states"
        },
        listeners: {
            exception: function(proxy, response, operation, opts) {
                if(typeof(operation.error) == "string") {
                    Ext.Msg.alert("Error", "Connection to server interrupted");
                }
            }
        }
    }
});

以下是firebug中服务器返回的数据：

{"states":[{"stateId":"1","state":"AL"},{"stateId":"2","state":"AK"},
{"stateId":"3","state":"AS"},{"stateId":"4","state":"AZ"},{"stateId":"5","state":"AR"},           
{"stateId":"6","state":"CA"},{"stateId":"7","state":"CO"},{"stateId":"8","state":"CT"},
{"stateId":"9","state":"DE"},{"stateId":"10","state":"DC"},
{"stateId":"11","state":"FM"},{"stateId":"12","state":"FL"},
{"stateId":"13","state":"GA"},{"stateId":"14","state":"GU"},
{"stateId":"15","state":"HI"},{"stateId":"16","state":"ID"},
{"stateId":"17","state":"IL"},{"stateId":"18","state":"IN"},
{"stateId":"19","state":"IA"},{"stateId":"20","state":"KS"},
{"stateId":"21","state":"KY"},{"stateId":"22","state":"LA"},
{"stateId":"23","state":"ME"},{"stateId":"24","state":"MH"},
{"stateId":"25","state":"MD"},{"stateId":"26","state":"MA"},
{"stateId":"27","state":"MI"},{"stateId":"28","state":"MN"},
{"stateId":"29","state":"MS"},{"stateId":"30","state":"MO"},
{"stateId":"31","state":"MT"},{"stateId":"32","state":"NE"},
{"stateId":"33","state":"NV"},{"stateId":"34","state":"NH"},
{"stateId":"35","state":"NJ"},{"stateId":"36","state":"NM"},
{"stateId":"37","state":"NY"},{"stateId":"38","state":"NC"},
{"stateId":"39","state":"ND"},{"stateId":"40","state":"MP"},
{"stateId":"41","state":"OH"},{"stateId":"42","state":"OK"},
{"stateId":"43","state":"OR"},{"stateId":"44","state":"PW"},
{"stateId":"45","state":"PA"},{"stateId":"46","state":"PR"},
{"stateId":"47","state":"RI"},{"stateId":"48","state":"SC"},
{"stateId":"49","state":"SD"},{"stateId":"50","state":"TN"}, 
{"stateId":"51","state":"TX"},{"stateId":"52","state":"UT"},
{"stateId":"53","state":"VT"},{"stateId":"54","state":"VA"},
{"stateId":"55","state":"VI"},{"stateId":"56","state":"WA"},
{"stateId":"57","state":"WV"},{"stateId":"58","state":"WI"},
{"stateId":"59","state":"WY"}]}

以下是数据应绑定到的组合：

{
                                xtype: 'combo',
                                fieldLabel: 'State',
                                store: store,
                                displayField: 'state',
                                valueField: 'stateId',
                                anchor:'97%',
                                itemId: 'fatherState',
                                editable: false,
                                allowBlank: false,
                                emptyText: 'Select a state',
                                tabIndex: 6,
                                queryMode: 'local'
                            }

尝试更改后面的两个文件

存储

    Ext.define("Iip.store.giip.other.States", {
        extend: "Ext.data.Store",
        config: {
           storeId:"states-store",
           model: "Iip.model.giip.other.State",
           autoLoad: false,
           buffered: true,
           proxy: {
              type: "ajax",
              actionMethods: {
                  read: "POST"
              },
             api: {
                read: "indexes/common_index.php"
              },
              reader: {
                type: "json",
                root: "states"
             },
             listeners: {
                 exception: function(proxy, response, operation, opts) {
                 if(typeof(operation.error) == "string") {
                      Ext.Msg.alert("Error", "Connection to server interrupted");
                 }
             }
          }
        }
      }

    });

模型：

    Ext.define('Iip.model.giip.other.State', {
          extend: 'Ext.data.Model',
          idProperty: "stateId",

          fields:[
            {name: "stateId", type: "int"},
             {name: "state", type: "string"}
          ]


   });

为什么我的商店即使返回数据也不会加载数据
