javascript - ToggleClass 和 RemoveClass 不起作用

标签 javascript jquery html css jquery-ui

我已经创建了记录播放器的动态 boostrap 卡。我是 Jquery 和 CSS/scss 的初学者。

我将根据数据库中的数据生成多张助推卡。为了简单起见，我在下面的例子中只写了 2 张助推卡。 我有一个音乐容器类，每张卡都有 1)控制播放和 2)乙烯基(电唱机)。 我的问题是如何在任何时候只允许播放 1 个控制播放，比如是否已经播放了 1 个控制播放，如果我单击另一个控制播放，则之前的控制播放停止并且黑胶唱片将翻转回专辑封面。换句话说，在任何给定时间都只允许 1 个唱机播放 vinly 动画。 ToggleClass 不工作，removeClass 也不工作。有时，即使我点击一次，也会为两个控制播放元素调用点击事件(我使用代理来避免这种情况，但它似乎不起作用)

错误:当我运行 fiddle 时，第一次单击 control-play1 时，会显示两个音乐播放器容器的乙烯基，而不是仅显示第一个，当再次单击 control-play1 时它们会关闭。如果你点击 2nd control-play，它只会显示 2nd vinly。这是一种不寻常的行为。

JS

          function MusicPlayer(mp, id) {
        this.mpc = mp;
        this.initEvents(id);

      }

      MusicPlayer.prototype = {
        initEvents: function(id) {
          var obj = this;
          obj.mpc.on('click', function(event) {

            var others = $("div.music-player-container").not($(this));

            $.each(others, function(index, value) {
              alert("other non-clicked players :" + $(value).attr("id") + " ; is it playing?" + $(value).is('.is-playing .vinyl'));
              if ($(value).is('.is-playing .vinyl')) {
                // $(value).removeClass('is-playing');
                //$(value).toggleClass('is-playing', false);
                $(value).removeClass('is-playing');
                $(value).addClass('is-not-playing');

                $(value).toggleClass('is-not-playing', true);

              }

            });
            alert("Current clicked music-Player-Container being toggled :" + $(this).attr("id"));
            $(this).toggleClass('is-playing');

            event.stopPropagation();

          });
        }
      }

      $(function() {

        var $div = $('#content');
        $(".control-play").bind('click', $.proxy(function(event) {
          //Get Control-Play clicked
          var cplay_clicked = $(event.target).attr('id');
          alert("control-player-clicked:" + cplay_clicked);
          //Get Music-Player-Container that has clicked Control-Play inside it
          var $musiPlayerContainer = $div.find('#' + event.target.dataset.id + 'mpc');
          var mpc = new MusicPlayer($musiPlayerContainer, event.target.dataset.id);
          $('div.music-player-container').removeClass('is-playing');
        }, this));

JS Fiddle Here

如果我不创建 MusicPlayerContainer 对象或按照建议使用 bind()，在 fiddle 中，它不起作用。

$(function() {

        var $div = $('#content');
                    $(".control-play").on('click', function (event) {

          //Get Control-Play clicked
          var cplay_clicked = $(event.target).attr('id');
          alert("control-player-clicked:" + cplay_clicked);
          //Get Music-Player-Container that has clicked Control-Play inside it
          var $musiPlayerContainer = $div.find('#' + event.target.dataset.id + 'mpc');

            var others = $("div.music-player-container").not($(this));

            $.each(others, function(index, value) {
              alert("other non-clicked players :" + $(value).attr("id") + " ; is it playing?" + $(value).is('.is-playing .vinyl'));
              if ($(value).is('.is-playing .vinyl')) {
                // $(value).removeClass('is-playing');
                //$(value).toggleClass('is-playing', false);
                $(value).removeClass('is-playing');
                $(value).addClass('is-not-playing');

                $(value).toggleClass('is-not-playing', true);

              }

            });

            alert("Current clicked music-Player-Container being toggled :" + $(this).attr("id"));
            $(this).toggleClass('is-playing');

            event.stopPropagation();
         $('div.music-player-container').removeClass('is-playing');
        }, 
        );
      });

最佳答案

正如我在评论中提到的，您的 fiddle 中 HTML 的第 24 至 28 行显示为:

</div>
<!-2nd one->


<div class="music-player-container" id="2mpc">

这无法关闭之前的 <div>带有“音乐播放器容器”类。您将要添加另一个 </div> ，像这样:

  </div>
</div>
<!-2nd one->
<div class="music-player-container" id="2mpc">

您还缺少一个 </div>在代码的末尾。更正可以在这里看到:https://jsfiddle.net/Twisty/ysLmyzb7/1/

关于我评论的第二部分，您可能需要考虑使用 jQuery UI 小部件工厂 ($.widget())。

Create stateful jQuery plugins using the same abstraction as all jQuery UI widgets.

一个这样的例子:

$(function() {
  $.widget("custom.musicPlayer", {
    options: {
      autoPlay: false,
      singlePlayer: true
    },
    playing: false,
    id: null,
    playButton: null,
    source: null,
    _create: function() {
      this.id = this.element.attr("id");
      console.log("New MPC: ", this.id);
      this.element.addClass("ui-mp");
      this.playButton = this.element.find(".control-play");
      this.source = this.element.find(".control-play").data("src");
      this._on(this.playButton, {
        click: "togglePlay"
      });
      if (this.options.autoPlay) {
        console.log(this.id + ": AutoPlay Enabled.");
        this.play();
      }
      console.log(this);
    },
    togglePlay: function() {
      if (this.playing) {
        this.stop();
      } else {
        this.play()
      }
    },
    play: function() {
      console.log(this.id + ": event, play");
      if (this.options.singlePlayer) {
        // Stop all other players
        $(".ui-mp").not(this.element).musicPlayer("stop");
      }
      this.playing = true;
      $(this.element).addClass("is-playing");
    },
    stop: function() {
      console.log(this.id + ": event, stop");
      this.playing = false;
      $(this.element).removeClass("is-playing");
    }
  });
  $(".music-player-container").musicPlayer();
});
