如何使标记动态标记正在进行的任何地方

9

我的标记有问题，我希望标记可以拉伸以标记进度条上的任何位置

如下图所示

问题：我想选择进度条上的任意点并能够拉伸标记，该标记可以是多个标记点。

我不知道如何使用下面的代码：

var player = videojs('demo');

player.markers({
   markerStyle: {
      'width':'9px',
      'border-radius': '40%',
      'background-color': 'orange'
   },
   markerTip:{
      display: true,
      text: function(marker) {
         return "I am a marker tip: "+ marker.text;
      }
   },
   breakOverlay:{
      display: true,
      displayTime: 4,
      style:{
         'width':'100%',
         'height': '30%',
         'background-color': 'rgba(10,10,10,0.6)',
         'color': 'white',
         'font-size': '16px'
      },
      text: function(marker) {
         return "This is a break overlay: " + marker.overlayText;
      },
   },
   markers: [
      {time: 9.5, text: "this", overlayText: "1", class: "special-blue"},
      {time: 16,  text: "is", overlayText: "2"},
      {time: 23.6,text: "so", overlayText: "3"},
      {time: 28,  text: "cool", overlayText: "4"}
   ]
});

您是否要由用户添加标记？因此，如果单击进度条，它们会添加标记吗？他们可以拉伸该标记吗？

做到这一点的一种方法是在seekbar上挂入mousedown和mousemove事件。使用自定义类在mousedown上添加标记。然后在mousemove上计算移动量，并使用自定义类将宽度添加到标记元素。

请参阅以下示例：

var player = videojs('demo');

// Set variable so we can add values later
let lastAddedMarker = null;
let moving = false;
let seekBar = player.controlBar.progressControl.seekBar;
let startPoint = 0;

// When seekbar is clicked add marker and set values to startpoint and set moving flag to true
seekBar.on('mousedown', function(event) {
  var seekBarEl = this.el();
  startPoint = videojs.dom.getPointerPosition(seekBarEl, event).x;

  player.markers.add([{
    time: player.currentTime(),
    text: "I'm new",
    overlayText: "I'm new",
    class: 'custom-marker'
  }]);

  lastAddedMarker = jQuery(".custom-marker");
  moving = true;
});

// When user moves while on seekbar get the width and set it to 'custom-marker' class
seekBar.on("mousemove", function(e) {
  if (moving) {
    let seekBarEl = this.el();
    let movingPoint = videojs.dom.getPointerPosition(seekBarEl, event).x;
    let containerWidth = jQuery(seekBarEl).width();
    let markerWidth = containerWidth * (movingPoint - startPoint);
    lastAddedMarker.width(markerWidth + "px");
  }
});

jQuery(document).on("mouseup", function() {
  moving = false;
});

player.markers({
  markerStyle: {
    'width': '9px',
    'border-radius': '2px',
    'background-color': 'orange'
  },
  markerTip: {
    display: true,
    text: function(marker) {
      return "I am a marker tip: " + marker.text;
    }
  },
  onMarkerClick: function(marker) {
    console.log("AS");
  },
  breakOverlay: {
    display: true,
    displayTime: 4,
    style: {
      'width': '100%',
      'height': '30%',
      'background-color': 'rgba(10,10,10,0.6)',
      'color': 'white',
      'font-size': '16px'
    },
    text: function(marker) {
      return "This is a break overlay: " + marker.overlayText;

在需要指针的位置，只需将时间放到中time: 20.5并增加的宽度markerStyle: { 'width': '190px' }，这样您的视频进度条中就会排得很长！

开始了

var player = videojs('demo');

player.markers({
   markerStyle: {
      'width':'190px',
      'border-radius': '2px',
      'background-color': 'orange'
   },
   markerTip:{
      display: true,
      text: function(marker) {
         return "I am a marker tip: "+ marker.text;
      }
   },
   breakOverlay:{
      display: true,
      displayTime: 120,
      style:{
         'width':'100%',
         'height': '30%',
         'background-color': 'rgba(10,10,10,0.6)',
         'color': 'white',
         'font-size': '16px'
      },
      text: function(marker) {
         return "This is a break overlay: " + marker.overlayText;
      },
   },
   markers: [
      {time: 20.5, text: "this", overlayText: "1", class: "special-blue"},
   ]
});
