如何使videojs标记可滑动或可移动

Question

我想移动我的 markers 每当它随着搜索滑动时。我希望我的标记与 jqueryui-slider

完全相同 slidable

问题： 我希望我的 markers（两者）与 jqueryui-range 滑块一样可滑动，如下例中的视频所示：

var player = videojs('example_video_1');

function markplayer(){
var inTimeOutTimeList = [6.333,27.667];
        for(var i = 0; i < inTimeOutTimeList.length; i++){
            player.markers.add([{
            time: inTimeOutTimeList[i],
            text: inTimeOutTimeList[i]
        }]);

        var icon = (i == 0) ? '[' : ']';
        $(".vjs-marker[data-marker-time='"+inTimeOutTimeList[i]+"']").html(icon);
    }
};

player.markers({
   breakOverlay:{
      display: true,
      displayTime: 120,
      style:{
         'width':'100%',
         'height': '30%',
         'background-color': 'rgba(10,10,10,0.6)',
         'color': 'white',
         'font-size': '16px'
      }
   },
   markers: [
      {time:10, startTime:10, endTime:60, text: "this", overlayText: "1", class: "special-blue"},
   ]
});

setTimeout(function(){
 markplayer();    
},2000);

 $( "#slider-range" ).slider({
      range: true,
      min: 0,
      max: 500,
      values: [ 75, 300 ],
      slide: function( event, ui ) {
        $( "#amount" ).val( "$" + ui.values[ 0 ] + " - $" + ui.values[ 1 ] );
      }
    });

.vjs-fluid {
            overflow: hidden;
         }
         #example_video_1 .vjs-control-bar {

请帮助我提前谢谢！！！

Answer 1

首先，使用 jQuery UI 的内置方法使您的标记可拖动。

$('body').on('mousedown', '.vjs-marker', function(e) {
    $(e.target).draggable({
      axis: 'x',
      containment: '.vjs-progress-control',
    });
}).on('mouseup', function(e) {
    $('.vjs-marker').css('top','-8px');   
});

由于标记想要向上移动到进度条的顶部边缘，我在 mouseup 上给了它一个 top: -8px。

然后，将 onMarkerClick 方法添加到您的 player.markers() 调用以更新时间。

onMarkerClick: function(marker) {    
    marker.time = player.currentTime();
    player.markers.updateTime();
},

而且我注意到您在 10 秒时添加了一个空白标记，所以我将其替换为一个空数组。

markers: []

最后，我添加了一些 Prev 和 Next 按钮，这样您就可以看到标记在滑动后起作用了。

编辑：

查看后，我意识到我的解决方案缺少一些东西。与范围滑块示例不同，我的标记可以相互交叉。

所以我用draggable对象的drag属性来限制标记的范围

...    
drag: function( e, ui ) {        
  if ( $(e.target).index('.vjs-marker') === 0 ) {
    const outPosition = parseInt( $('.vjs-slider .vjs-marker:eq(1)').css('left') );          
    ui.position.left = Math.min( outPosition, ui.position.left );
  }
  else {
    const inPosition = parseInt( $('.vjs-slider .vjs-marker:eq(0)').css('left') );
    ui.position.left = Math.max( inPosition, ui.position.left );        
  }                
}
...

var player = videojs('example_video_1');

function markplayer() {
  var inTimeOutTimeList = [1.2, 4.2];
  var labelList = ['In Point', 'Out Point'];
  for (var i = 0; i < inTimeOutTimeList.length; i++) {
    player.markers.add([{
      time: inTimeOutTimeList[i],
      text: labelList[i]
    }]);

    var icon = (i == 0) ? '[' : ']';
    $(".vjs-marker[data-marker-time='" + inTimeOutTimeList[i] + "']").html(icon);
  }
};

player.markers({
  breakOverlay: {
    display: true,
    displayTime: 120,
    style: {
      'width': '100%',
      'height': '30%',
      'background-color': 'rgba(10,10,10,0.6)',
      'color': 'white',
      'font-size': '16px'
    }
  },
  onMarkerClick: function(marker, index) {
    marker.time = player.currentTime();
    player.markers.updateTime();
  },
  markers: []
});

setTimeout(function() {
  markplayer();
}, 2000);

$(function() {
  $('body').on('mousedown', '.vjs-marker', function(e) {
    $(e.target).draggable({
      axis: 'x',
      containment: '.vjs-progress-control',
      drag: function(e, ui) {
        if ($(e.target).index('.vjs-marker') === 0) {
          const outPosition = parseInt( $('.vjs-slider .vjs-marker:eq(1)').css('left') );
          ui.position.left = Math.min(outPosition, ui.position.left);
        } else {
          const inPosition = parseInt( $('.vjs-slider .vjs-marker:eq(0)').css('left') );
          ui.position.left = Math.max(inPosition, ui.position.left);
        }
      }
    });
  }).on('mouseup', function(e) {
    $('.vjs-marker').css('top', '-8px');
  });

  $("#prev").click(function() {
    player.markers.prev();
  });
  $("#next").click(function() {
    player.markers.next();
  });
});

body {
  text-align: center;

Answer 2

我刚刚在你之前的 slide 事件中添加了几行，我使用了这个事件的 .values() 来获取开始和结束值，然后做了一个 marker.reset() 来添加新标记

...
slide: function twsr(event, ui) {
  // $( "#amount" ).val( "$" + ui.values[ 0 ] + " - $" + ui.values[ 1 ] );
  player.markers.reset([
    {
      time: ui.values[0],
      text: "this",
      overlayText: "1",
      class: "special-blue"
    },
    {
      time: ui.values[1],
      text: "this",
      overlayText: "1",
      class: "special-blue"
    }
  ]);
  for (var i = 0; i < ui.values.length; i++) {
    var icon = i == 0 ? "[" : "]";
    $(".vjs-marker[data-marker-time='" + ui.values[i] + "']").html(icon);
  }
}
...

注意：我对setTimeOut感觉不太好，以后有空再去看看。

如果我答对了你的问题，这就是你正在寻找的实现，工作片段:

$(document).ready(function() {
  var player = videojs("example_video_1");

  function markplayer() {
    $("#slider-range").slider({
      range: true,
      min: 0,
      max: player.duration(),
      values: [6.333, 27.667],
      slide: function(event, ui) {
        // $( "#amount" ).val( "$" + ui.values[ 0 ] + " - $" + ui.values[ 1 ] );
        player.markers.reset([
          {
            time: ui.values[0],
            text: "this",
            overlayText: "1",
            class: "special-blue"
          },
          {

            text: "this",
            overlayText: "1",
            class: "special-blue"
          }
        ]);
        for (var i = 0; i < ui.values.length; i++) {
          var icon = i == 0 ? "[" : "]";
          $(".vjs-marker[data-marker-time='" + ui.values[i] + "']").html(icon);
        }
      }
    });

    var inTimeOutTimeList = [6.333, 27.667];
    for (var i = 0; i < inTimeOutTimeList.length; i++) {
      player.markers.add([
        {
          time: inTimeOutTimeList[i],

      ]);

      var icon = i == 0 ? "[" : "]";
      $(".vjs-marker[data-marker-time='" + inTimeOutTimeList[i] + "']").html(
        icon
      );
    }
  }

      }
    },
    markers: [
      {
        time: 10,
        startTime: 10,
        endTime: 60,
        text: "this",
        overlayText: "1",
        class: "special-blue"
      }
    ]
  });

  setTimeout(function() {
    markplayer();
  }, 100);

Answer 3

我真的很喜欢所以我决定对其进行调整以满足问题的要求。

我只是将范围滑块直接移到进度条上并给了它 opacity: 0;

$(document).ready(function() {
  var player = videojs("example_video_1");

  function markplayer() {
    $("#slider-range").slider({
      range: true,
      min: 0,
      max: player.duration(),
      values: [6.333, 27.667],
      slide: function(event, ui) {
        // $( "#amount" ).val( "$" + ui.values[ 0 ] + " - $" + ui.values[ 1 ] );
        player.markers.reset([{
            time: ui.values[0],
            text: "this",
            overlayText: "1",
            class: "special-blue"
          },
          {
            time: ui.values[1],
            text: "this",
            overlayText: "1",
            class: "special-blue"
          }
        ]);
        for (var i = 0; i < ui.values.length; i++) {
          var icon = i == 0 ? "[" : "]";
          $(".vjs-marker[data-marker-time='" + ui.values[i] + "']").html(icon);
        }
      }
    });

    var inTimeOutTimeList = [6.333, 27.667];
    for (var i = 0; i < inTimeOutTimeList.length; i++) {
      player.markers.add([{
        time: inTimeOutTimeList[i],
        text: inTimeOutTimeList[i]
      }]);

      var icon = i == 0 ? "[" : "]";
      $(".vjs-marker[data-marker-time='" + inTimeOutTimeList[i] + "']").html(
        icon
      );
    }
  }

  player.markers({
    breakOverlay: {
      display: true,
      displayTime: player.duration(),
      style: {
        width: "100%",
        height: "30%",
        "background-color": "rgba(10,10,10,0.6)",
        color: "white",
        "font-size": "16px"
      }
    },
    markers: [{
      time: 10,
      startTime: 10,
      endTime: 60,
      text: "this",
      overlayText: "1",
      class: "special-blue"
    }]
  });

  setTimeout(function() {
    $('#slider-range').appendTo('#example_video_1');
    markplayer();
  }, 100);
});
