如何将JSON文件中的信息加载到播放器中？

这是JSON本身：

{"tracks":[
    {
        "title": "Some Track 1",
        "trackname": "Some_track_name_1"
    },
    {
        "title": "Some Track 2",
        "trackname": "Some_track_name_2"
    },
    {
        "title": "Some Track 3",
        "trackname": "Some_track_name_3"
    }
]}

这是我的JS的想法。

$.getJSON("path/to/playlist.json",
function(....){

//Get JSON data and generate a playlist
//Playlists are generated with:
    customPlaylist.add({
        title: title var,
        mp3: 'track path' + filename var + '.mp3' ,
    });   
});

创建自定义播放列表后，等待jPlayer将其设置为默认播放列表myPlaylist：

$("#Playlist_1").click(function() {
    myPlaylist.setPlaylist([

       set the generated playlist "customPlaylist" as the 
       default playlist "myPlaylist" here....

    ]);

这样我认为我会有多个播放列表，因此用户可以选择播放哪个播放列表。

我对JS和JSON的了解有限，所以我所拥有的只是粗略的想法。

你正朝着正确的方向前进！

您只需使用您要回复的变量即可。轨道是一个数组，因此您可以使用forEach;

循环遍历它

typedef struct Employee{
    char name[MAX_SIZE];
    int salary;
    int experience;
} employee_t;

employee_t *readEmployee(employee_t *emp)
{
    printf("Please enter Employee's name:(max 19 chars)");
    scanf("%s", emp->name); // -> operator

    printf("Please enter Employee's salary:");
    scanf("%d", &emp->salary); // %d

    printf("Please enter Employee's experience:"); 
    scanf("%d",&emp->experience);

    return emp;
}

int main(void) {
    employee_t *newEmployee, tmp; // newEmployee is now a pointer

    newEmployee = readEmployee( &tmp ); // newEmployee now points to tmp    
    printf("Employee name is %s, salary is %d, experience is %d years\n", newEmployee->name, newEmployee->salary, newEmployee->experience);

    return 0;
}
