javascript - 使用参数从 Angular Controller 启动功能

Question

我需要启动一个函数，该函数需要我得到的 json 中的参数，请求是:

app.controller('getDataCtrl', function ($scope, $http, $ionicLoading) {

$http({
    method: "POST",
    url: "http://someurl/GetPlaylist",
    dataType: "json",
    contentType: "application/json; charset=utf-8"
}).then(function mySucces(response) {

    $scope.allTracks = response.data;
    $scope.recentTracks = response.data.Tracks;
//now i want to luanch the function below that written in a different js file
//and pass parameters
        **startCration(recentTracks[0].Song, recentTracks[0].Artist);**

}, function myError(response) {
    $scope.allTracks = response.statusText;
});
});

这是我需要启动的功能

function startCration(song, artist) {

    MusicControls.create({
        track: song,        
        artist: artist,                           
    }, onCreateSuccess, onCreateError);

但是调用成功后似乎无法调用该函数

当您将所有轨道分配给 $scope.recentTracks 时，您应该引用 $scope.recentTracks 而不仅仅是 recentTracks。

startCration(recentTracks[0].Song, recentTracks[0].Artist);

应该是

startCration($scope.recentTracks[0].Song, $scope.recentTracks[0].Artist);
