使用可动态查询样式化列表

虽然我一直在上下寻找这个问题的答案，但我还是找不到它。如果互联网上有一个我还没有搜索过的隐藏角落确实包含这个问题的答案，请告诉我。

无论如何，在Dynatable网站上有一个示例来查询表中的特定值。如果您的输入 html 确实是一个表格，这似乎有效，但如果您使用的是风格化列表这在我的情况下会产生以下错误：

Uncaught TypeError: Cannot read property 'length' of null

这可以追溯到dynatable.jquery.js文件的第1582行：

    // Find an object in an array of objects by attributes.
// E.g. find object with {id: 'hi', name: 'there'} in an array of objects
findObjectInArray: function(array, objectAttr) {
  var _this = this,
      foundObject;
  for (var i = 0, len = array.length; i < len; i++) {
    var item = array[i];
    // For each object in array, test to make sure all attributes in objectAttr match
    if (_this.allMatch(item, objectAttr, function(item, key, value) { return item[key] == value; })) {
      foundObject = item;
      break;
    }
  }

以下是我的选择元素：

        <select id="filter-prop" name="prop">
          <option>All</option>
          <option>First Run</option>
          <option>Rejected</option>
        </select>

以及我的列表的可动态转换：

            // Function that renders the list items from our records
        function ulWriter(rowIndex, record, columns, cellWriter) {
          var cssClass = record.prop, li;
          if (rowIndex % 3 === 0) { cssClass += ' first'; }
          li = '<li class="' + cssClass + '"><div class="thumbnail"><div class="thumbnail-image">' + record.thumbnail + '</div><div class="caption">' + record.caption + '</div></div></li>';
          return li;
        }
        // Function that creates our records from the DOM when the page is loaded
        function ulReader(index, li, record) {
          var $li = $(li),
              $caption = $li.find('.caption');
          record.thumbnail = $li.find('.thumbnail-image').html();
          record.caption = $caption.html();
          record.label = $caption.find('h3').text();
          record.description = $caption.find('p').text();
          record.color = $li.data('color');
          record.prop = $li.attr('class');
        }
        var pictable = $('#picturelist').dynatable({
          table: {
            bodyRowSelector: 'li'
          },
          features :{
            recordCount: false,
            sorting: false,
          },
          dataset: {
            perPageDefault: 10,
            perPageOptions: [5, 10, 15, 20]
          },
          writers: {
            _rowWriter: ulWriter
          },
          readers: {
            _rowReader: ulReader
          },
          params: {
            records: 'objects'
          }
        }).data('dynatable');

        $('#filter-prop').change( function() {
            var value = $(this).val();
            if (value === "All") {
                pictable.queries.remove("Prop");
            } else if (value === "First Run") {
                pictable.queries.add("Prop","span4 firstrun rejected");
                pictable.queries.add("Prop","span4 firstrun");
            } else if (value === "Rejected") {
                pictable.queries.add("Prop","span4 firstrun rejected");
                pictable.queries.add("Prop","span4 rejected");
            };
            pictable.process();
        });

与网站的示例相比，我没有太大变化。我做的最多的是将列表示例与查询示例合并。同样，如果我对表应用类似的方法，它似乎有效，但对于我的列表则不起作用。出了什么问题？
