考虑以下 JSON 结构: 更新:
[
{
"game0001": {
"-JfuVKIsUBH27DMJfWmL": {
"action": "STARTFIRSTHALF",
"team": "HOME"
},
"-JfuVLJGMgclLZ0Maduh": {
"action": "GOAL",
"team": "AWAY"
}
},
"$id": "events",
"$priority": null
},
{
"game0001": {
"gameRunning": false,
"startDate": "17/01/2015 17:27:42 PM"
},
"game0002": {
"gameRunning": true,
"startDate": "17/01/2015 19:45:59 PM"
},
"game0003": {
"gameRunning": false,
"scheduledDate": "17/01/2014 12:30:00 PM"
},
"$id": "games",
"$priority": null
}
]
如何在 HTML 中实现 AngularJS 的过滤？ 从一个非常基本的方式来看，我想要实现的目标如下:
<div ng-repeat="game in games">
<div ng-repeat="event in events | filter:game">
{{event.name}} - {{game.name}}
</div>
</div>
我有 2 个 map 游戏和事件，它们共享相同的键，例如(game0001、game0002)
在重复游戏时，我希望有一个内部事件转发器，并仅过滤共享相同 key /ID 的事件。
最佳答案
这是一个有效的 plunkr，我对您想要获取的数据做了假设:
http://plnkr.co/edit/DVwQaRZeZiagGEzY4lCy?p=preview
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.name = 'World';
$scope.games = {
"games": {
"game0001": {
"first": "a",
"second": "b"
},
"game0002": {
"first": "c",
"second": "d"
}
}
}
$scope.gamesKeys = Object.keys($scope.games['games']);
$scope.events = {
"events": {
"game0001": {
"event": {
"key": "a"
},
"event": {
"key": "b"
},
"event": {
"key": "c"
}
},
"game0002": {
"event": {
"key": "a"
},
"event": {
"key": "b"
},
"event": {
"key": "c"
}
}
}
}
$scope.eventsKeys = Object.keys($scope.events['events']);
});
重要的部分是这里的 ng-repeat:
<body ng-controller="MainCtrl">
<div ng-repeat="gameKey in gamesKeys">
<div ng-repeat="eventKey in eventsKeys">
event: {{events['events'][eventKey].event.key}} - game: {{games['games'][gameKey].first}}
</div>
</div>
</body>
