现效果如下：

由于我这边不需要其他按钮，就没写

数据是由后台提供，在这做了个小列子

后台代码

public ActionResult MusicPlayer(int musicId=0) {
 MusicPlayerModel model = new MusicPlayerModel();
 switch (musicId)
 {
 default:
 model.MusicName = "Believe-动画《海贼王》";
 model.CoverImg = "/Content/Music/Believe-cover.jpg";
 model.FileUrl = "/Content/Music/Believe.mp3";
 model.MusicStartSecond = 0;
 model.MusicEndSecond = 227;
 break;
 case 1:
 model.MusicName = "梦回还-动画《狐妖小红娘》";
 model.CoverImg = "/Content/Music/梦回还-cover.jpg";
 model.FileUrl = "/Content/Music/梦回还.mp3";
 model.MusicStartSecond = 0;
 model.MusicEndSecond = 250;
 break;
 }
 return View(model);
 }

页面代码

@using FunctionTest.Web.Areas.Function.Models;
@model MusicPlayerModel
@{
 ViewBag.Title = "MusicPlayer";
 Layout = "~/Areas/Function/Views/Shared/_FunctionLayout.cshtml";
}
<link href="~/Assets/Function/MusicPlayer/musicPlayer.css" rel="external nofollow" rel="stylesheet" />
