我是新的角度,想要创建模型数组,当我点击复选框,下面是我的代码..
$scope.selectedAlbumSongs = [{ 'name': 'song1','url': 'http://test/song1.mp3' },{ 'name': 'song2','url': 'http://test/song2.mp3' },{ 'name': 'song3','url': 'http://test/song3.mp3' }]; $scope.playList = {};
HTML:
<fieldset data-role="controlgroup"> <legend>Select songs to play</legend> <label ng-repeat="song in selectedAlbumSongs"> <input type="checkBox" name="{{song.url}}" id="{{song.name}}" ng-model="playList[song.url]"> <label for="{{song.name}}">{{song.name}}</label> </label> </fieldset>
上面的代码更新播放列表,如下所示,当我点击复选框
{ "http://test/test1.mp3": true,"http://test/test2.mp32": true,"http://test/test3.mp3": false }
但是我想以下面的格式创建ng模型,并且在复选框未被选中时删除该对象(例如,如果取消选中song3,从数组中删除song3对象)。你能告诉我如何写这个逻辑?
预期:
[{ name: "song1",url: "http://test/song1.mp3" },{ name: "song2",url: "http://test/song2.mp3" }]
你可以这样做:
$scope.selectedAlbumSongs = [ { 'name': 'song1','url': 'http://test/song1.mp3' },{ 'name': 'song2','url': 'http://test/song2.mp3' },{'name': 'song3','url': 'http://test/song3.mp3' }]; $scope.selectedSongs = function () { $scope.playList = $filter('filter')($scope.selectedAlbumSongs,{checked: true}); }
然后,当选择更改时,简单调用selectedSongs():
<input type="checkBox" name="{{song.url}}" id="{{song.name}}" ng-model="song.checked" ng-change="selectedSongs()">
