如何解决 Chrome 中的 VIS Timeline 组排序错误？

Question

Vis.js Timeline 在 Chrome 中有一个错误（仅）。当有超过 10 个组（卡车）时，它会更改组的顺序。

In this exmaple in Chrome 浏览器 Truck 11 显示在第一行，Truck 2 显示在 卡车10。在其他浏览器中组的顺序是正确的。

如何让 Chrome 以正确的顺序显示组？

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/vis/4.9.0/vis.min.js"></script>
<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/vis/4.9.0/vis.min.css">
<div id="js__timeline"></div>

JS代码：

<script>
  /**
   * Get URL parameter
   * http://www.netlobo.com/url_query_string_javascript.html
   */
  function gup( name ) {
    name = name.replace(/[\[]/,"\[").replace(/[\]]/,"\]");
    var regexS = "[\?&]"+name+"=([^&#]*)";
    var regex = new RegExp( regexS );
    var results = regex.exec( window.location.href );
    if( results == null )
      return "";
    else
      return results[1];
  }

  // get selected item count from url parameter
  var count = (Number(gup('count')) || 1000);

  // create groups
  var groups = new vis.DataSet([
    {id: 1, content: 'Truck&nbsp;1'},
    {id: 2, content: 'Truck&nbsp;2'},
    {id: 3, content: 'Truck&nbsp;3'},
    {id: 4, content: 'Truck&nbsp;4'},
    {id: 5, content: 'Truck&nbsp;5'},
    {id: 6, content: 'Truck&nbsp;6'},
    {id: 7, content: 'Truck&nbsp;7'},
    {id: 8, content: 'Truck&nbsp;8'},
    {id: 9, content: 'Truck&nbsp;9'},
    {id: 10, content: 'Truck&nbsp;10'},
    {id: 11, content: 'Truck&nbsp;11'},
    {id: 12, content: 'Truck&nbsp;12'},
    {id: 13, content: 'Truck&nbsp;13'},
    {id: 14, content: 'Truck&nbsp;14'},
    {id: 15, content: 'Truck&nbsp;15'},
    {id: 16, content: 'Truck&nbsp;16'},
    {id: 17, content: 'Truck&nbsp;17'},
    {id: 18, content: 'Truck&nbsp;18'},
    {id: 19, content: 'Truck&nbsp;19'},
    {id: 20, content: 'Truck&nbsp;20'},
    {id: 21, content: 'Truck&nbsp;21'}
  ]);

  // create items
  var items = new vis.DataSet();

  var order = 1;
  var truck = 1;
  for (var j = 0; j < 21; j++) {
    var date = new Date();
    for (var i = 0; i < count/10; i++) {
      date.setHours(date.getHours() +  4 * (Math.random() < 0.2));
      var start = new Date(date);

      date.setHours(date.getHours() + 2 + Math.floor(Math.random()*4));
      var end = new Date(date);

      items.add({
        id: order,
        group: truck,
        start: start,
        end: end,
        content: 'Order ' + order
      });

      order++;
    }
    truck++;
  }

  // specify options
  var options = {
    stack: false,
    start: new Date(),
    end: new Date(1000*60*60*24 + (new Date()).valueOf()),
    editable: true,
    margin: {
      item: 10, // minimal margin between items
      axis: 5   // minimal margin between items and the axis
    },
    orientation: 'top'
  };

  // create a Timeline
  var container = document.getElementById('js__timeline');
  timeline = new vis.Timeline(container, null, options);
  timeline.setGroups(groups);
  timeline.setItems(items);

  document.getElementById('count').innerHTML = count;
</script>

Answer 1

据我所知，您还没有为组定义任何顺序，因此它们的顺序未确定。

您可以将选项 groupOrder 设置为 'id' 以让群组按其 ID 排序，或在那里提供您自己的排序功能，或为所有群组提供属性顺序。

来自 groupOrder 上的文档：

Order the groups by a field name or custom sort function. By default, groups are ordered by a property order (if set). If no order properties are provided, the order will be undetermined.
