EDIT: ANSWERED Worked it out. Posting to Stack Overflow actually pointed me to the answer!

Basically it appears there s something funny about Ext.data.JsonStore with Sencha Touch. Maybe some of the defaults aren t exactly as expected. Renamed the file to test.json (not sure if that was neccessary)

。 如何分类这种xml数据格式? 工作

Ext.regModel( tester , {
         idProperty:  name ,
         fields: [ name ,  data1 ,  data2 ,  data3 ]
     });
      var store = new Ext.data.Store({
         model:  tester ,
         autoLoad: true,
         proxy: {
             type:  ajax ,
             method:  GET ,
             url:  test.json ,
             reader: {
                 type:  json ,
                 root:  test 
             }
         },
         listeners: {
             load: function(obj, records){
                 Ext.each(records, function(rec){
                     console.log(rec.get( name ));
                 });
             }
         }
     }); 

ORIGINAL QUESTION

I m sure there s some major thing i m not doing right but i m having trouble getting data into a chart from a JSON source.

这是我下面的《仓储法典》,是一纸 working。

    window.store1 = new Ext.data.JsonStore({
         autoload: true,
         url:  test.php ,
      root:  test ,
         idProperty:  name ,     
         fields: [ name ,  data1 ,  data2 ,  data3 ]
     });

地点

测试.php =

{ "test" : {
        "data": [
          { "name": "Mon", "data1":47.5, "data2":20,    "data3":10},
                { "name": "Tue", "data1":30, "data2":30, "data3":30},
                { "name": "Wed", "data1":31.1, "data2":40, "data3":20},
                { "name": "Thu", "data1":21.1, "data2":20, "data3":30},
                { "name": "Fri", "data1":20.7, "data2":20, "data3":10},
                { "name": "Sat", "data1":22.4, "data2":30, "data3":30},
                { "name": "Sun", "data1":28.3, "data2":40, "data3":20}


        ]
    }
    }

如果我手把数据编成像以下的图表系列,则数据是正确的。

 window.store1 = new Ext.data.JsonStore({

            fields: [ name ,  data1 ,  data2 ,  data3 ],
            data: [
            { "name": "Mon", "data1":47.5, "data2":20, "data3":10},
            { "name": "Tue", "data1":30, "data2":30, "data3":30},
            { "name": "Wed", "data1":31.1, "data2":40, "data3":20},
            { "name": "Thu", "data1":21.1, "data2":20, "data3":30},
            { "name": "Fri", "data1":20.7, "data2":20, "data3":10},
            { "name": "Sat", "data1":22.4, "data2":30, "data3":30},
            { "name": "Sun", "data1":28.3, "data2":40, "data3":20}
            ]
        });

绘制脱蚊图(新信 Touch图)产生一个数据阵列,如此,我可以找到一个通过简单的JSON来源进行居住的例子。

window.generateData = function(n, floor) {
            var data = [],
                p = (Math.random() * 11) + 1,
                i;

            floor = (!floor && floor !== 0) ? 20 : floor;

            for (i = 0; i < (n || 12); i++) {
                data.push({
                    name: Date.monthNames[i % 12],
                    2008: Math.floor(Math.max((Math.random() * 100), floor)),
                    2009: Math.floor(Math.max((Math.random() * 100), floor)),
                    2010: Math.floor(Math.max((Math.random() * 100), floor)),
                    data1: Math.floor(Math.max((Math.random() * 100), floor)),
                    data2: Math.floor(Math.max((Math.random() * 100), floor)),
                    data3: Math.floor(Math.max((Math.random() * 100), floor)),
                    data4: Math.floor(Math.max((Math.random() * 100), floor)),
                    data5: Math.floor(Math.max((Math.random() * 100), floor)),
                    data6: Math.floor(Math.max((Math.random() * 100), floor)),
                    data7: Math.floor(Math.max((Math.random() * 100), floor)),
                    data8: Math.floor(Math.max((Math.random() * 100), floor)),
                    data9: Math.floor(Math.max((Math.random() * 100), floor)),
                    time: Math.floor(Math.max((Math.random() * 100), floor)),
                    registrations: Math.floor(Math.max((Math.random() * 100), floor)),
                    hours: Math.floor(Math.max((Math.random() * 100), floor)),
                    iphone: Math.floor(Math.max((Math.random() * 100), floor)),
                    android: Math.floor(Math.max((Math.random() * 100), floor)),
                    ipad: Math.floor(Math.max((Math.random() * 1000), floor))
                });
            }
            return data;
        };

 window.store2 = new Ext.data.JsonStore({
            fields: [ name ,  2008 ,  2009 ,  2010 ,  data4 ,  data5 ,  data6 ,  data7 ,  data8 ,  data9 ],
            data: generateData(6, 20)
        });

I d really appreciate if someone could point me in the right direction as to why the series data isn t loading.
