问题描述
我新的Web开发，我试图让与angular.js，hammer.js和面漆的移动Web应用程序。
I'm new to web dev and i'm trying to make and mobile webapp with angular.js, hammer.js and topcoat.
我有从这样一个JSON文件显示数据了一些麻烦：
I'm having some trouble on displaying data from a Json file like this one:
{
"version": "1",
"artists": {
"artist1": {
"name": "artist1name",
"jpeg": "../img/artist/artist1.jpg",
"albums": {
"album1": {
"type": "cd",
"title": "titlealbum1",
"subtitle": "subtitlealbum1",
"jpeg": "../img/album1.jpg",
"price": "12.00",
"anystring1": "anystring1album1",
"anystring2": "anystring2album1"
},
"album2": [{
"type": "cd",
"title": "titlealbum2",
"subtitle": "subtitlealbum2",
"jpeg": "../img/album2.jpg",
"price": "12.00",
"anystring1": "anystring1album2",
"anystring2": "anystring2album2"
}],
"album3": [{
"type": "cd",
"title": "titlealbum3",
"subtitle": "subtitlealbum3",
"jpeg": "../img/album3.jpg",
"price": "13.00",
"anystring1": "anystring1album3",
"anystring2": "anystring2album3"
}]
}
},
"artist2": {
"name": "artist2name",
"jpeg": "../img/artist/artist2.jpg",
我的js文件是这样的：
My js file is like this:
angular.module('list', [])
function ListCtrl ($scope, $http) {
$http({method: 'GET', url: 'json/json_price_1.json'}).success(function(data)
{
$scope.artists = data.artists; // response data
$scope.albums = data.artists.albums; /this is where im getting trouble
});
};
我的HTML文件是这样的：
My HTML file is like this:
<body ng-app="list">
<h3>Titulos</h3>
<div ng-controller="ListCtrl">
<ul ng-repeat="artist in artists">
<li >{{artist.name}}</li>
</ul>
</div>
<div ng-controller="ListCtrl">
<ul ng-repeat="album in albums">
<li >{{album.title}}</li> //not working here.
</ul>
</div>
我要显示所有专辑，如果我的用户选择一个特定的艺术家，我要过滤这些专辑。
这里的问题是如何将我选择在这个嵌套JSON。顺便说一句，在artist.name正确显示。
第二个问题是，我将如何筛选这些艺术家用文本字段。
Second question is, how will i filter those artists with a text field.
推荐答案
我建议是这样的：
$http({method: 'GET', url: 'json/json_price_1.json'}).success(function(data) {
$scope.artists = [];
angular.forEach(data.artists, function(value, key) {
$scope.artists.push(value);
});
$scope.isVisible = function(name){
return true;// return false to hide this artist's albums
};
});
和则：
<div ng-controller="ListCtrl">
<ul>
<li ng-repeat="artist in artists">{{artist.name}}</li>
</ul>
<ul ng-repeat="artist in artists" ng-show="isVisible(artist.name)">
<li ng-repeat="album in artist.albums">{{album.title}}</li>
</ul>
</div>
