使用纳克重复从对象属性中的数组访问项目 [英] Access items from array within object property using ng-repeat
本文介绍了使用纳克重复从对象属性中的数组访问项目的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我试图创建项目这种设置,这里的类别将是我所有专辑所有曲目简单分类。我试图将其设置是这样的:
enitoniApp.controller('musicItems',['$范围',函数($范围){
$ scope.albums = [
{
名称:'翻山越岭',
曲目:
{
名称:'翻山越岭',
裁判:otmt',
发布:0,
价格:0,
},
{
名称:'C3',
裁判:'冰',
发布:0,
价格:0,
}
]
}
]
}]);
和视图:
<身体GT;
< DIV ID =音乐指南NG控制器=musicItems>
< DIV ID =专辑>
< UL>
<李NG重复=专辑在专辑>
< DIV CLASS =标题> {{album.name}}< / DIV>
< UL>
<李NG重复=轨道albums.tracks> {{track.name}}< /李>
< / UL>
< /李>
< / UL>
< / DIV>
< / DIV>
< /身体GT;
预期的行为是angular.js会重蹈里
的专辑里面里
基础上如何许多轨道,在这种情况下为两个。但是,我不能让它访问轨道内的数组项金额
。
这就是我想实现:
<身体GT;
< DIV ID =音乐指南NG控制器=musicItems>
< DIV ID =专辑>
< UL>
<立GT;
< DIV CLASS =标题>翻山越岭< / DIV>
< UL>
<立GT;翻山越岭< /李>
<立GT;!C3< /李>
< / UL>
< /李>
< / UL>
< / DIV>
< / DIV>
< /身体GT;
解决方案
内蒙古 ngRepeat
应轨道album.tracks
(你的专辑的取值的)
<李NG重复=轨道album.tracks> {{track.name}}< /李>
<! - 额外的s在这里----- ^ - >
I'm trying to create a simple category with items kind of setup, where the categories will be all my albums with all the tracks. I've tried to set it up like this:
enitoniApp.controller('musicItems', ['$scope', function ($scope) {
$scope.albums = [
{
name: 'Over The Mountains',
tracks: [
{
name: 'Over The Mountains',
ref: 'otmt',
released: 0,
price: 0,
},
{
name: '!C3',
ref: 'ice',
released: 0,
price: 0,
}
]
}
]
}]);
and in the view:
<body>
<div id="allMusic" ng-controller="musicItems">
<div id="albums">
<ul>
<li ng-repeat="album in albums">
<div class="title">{{album.name}}</div>
<ul>
<li ng-repeat="track in albums.tracks">{{ track.name}}</li>
</ul>
</li>
</ul>
</div>
</div>
</body>
The expected behaviour is that angular.js will repeat the li
's inside the album li
based on how many tracks, which in this case is two. However, I cannot get it to access the amount of array items inside tracks
.
This is what I am trying to achieve:
<body>
<div id="allMusic" ng-controller="musicItems">
<div id="albums">
<ul>
<li>
<div class="title">Over The Mountains</div>
<ul>
<li>Over the mountains</li>
<li>!C3</li>
</ul>
</li>
</ul>
</div>
</div>
</body>
解决方案
Inner ngRepeat
should be track in album.tracks
(you have albums):
<li ng-repeat="track in album.tracks">{{ track.name}}</li>
<!-- extra "s" was here -----^ -->
