Question

我是离子的新手，我希望能够扩展一个简单的json数据集，以包含数组中的列表：我的json文件如下所示：

angular.module('starter.services', [])

/** A simple example service that returns some data. */
.factory('Bands', function() {

  var bands = [
         {"id": "0", name: 'U2', nationality: 'Irish', category: 'Rock', pic: "U2.jpg", url:"www.u2.com" },                     
       {
            "albums":
                {"album"
                    [
                        { "id": "101", name:"Songs Of Innocence", year:"2014", pic: "u2_soi_cover.jpg" },
                        { "id": "102", name:"No Line On The Horizon", year:"2009", pic: "u2_nloth_cover.jpg" },
                        { "id": "103", name:"How To Dismantle An Atomic Bomb", year:"2004", pic: "u2_htdaab_cover.jpg" },
                     ]
                },
      },
   {"id": "1", name: 'Silverchair', nationality: 'Australian', category: 'Grunge', pic: "silverchair.jpg", url:"www.silverchair.com/" },                        
       {
            "albums":
                {"album"
                    [
                        { "id": "102", name:"Frogstomp", year:"1995", pic: "sc_frogstomp_cover.jpg" },
                    ]
                },

},
 ];

return {
all: function() {
  return bandss;
},
get: function(bandId) {
  // Simple index lookup
  return bands[bandId];
  }
 }
 })

所以我已经能够使用重复返回乐队列表并传递乐队ID以显示各个乐队的详细信息。

我想不要将乐队页面扩展到它以返回专辑列表的详细信息，所以我猜测它会是这样的，但是我需要一些帮助来理解如何从列表中获取列表特定乐队ID。

 <ion-content>
      <div class="details">
      <img src="pics/bands/{{band.pic }}" />
    <h2>{{band.name}}</h2>
   <p>{{band.nationality}}</p>
   </div>
  <ion-list>
      <ion-item ng-repeat="album in albums" type="item-text-wrap" >
             <h2>{{album.name}}</h2>
      <p>{{album.year}}</p>
        </ion-item>
    </ion-list>
   </ion-content>

任何帮助我指明正确方向的帮助都会很棒。

您需要更改json格式，移动＆＃34;相册＆＃34;进入＆＃34;乐队＆＃34;，像这样：

[
  {
    "id": "0",
    "name": "U2",
    "nationality": "Irish",
    "category": "Rock",
    "pic": "U2.jpg",
    "url": "www.u2.com",
    "albums": [
        {
            "id"": "101",
            "name": "SongsOfInnocence",
            "year": "2014",
            "pic": "u2_soi_cover.jpg"
        }
    ]
  }
]

现在在你的观点的ng-repeat中：

<ion-item ng-repeat="album in band.albums" type="item-text-wrap" >
  <h2>{{album.name}}</h2>
  <p>{{album.year}}</p>
</ion-item>

Json列出了数组离子返回列表值
