javascript - 过滤器小部件不适用于 Tablesorter 中的 ajax

Question

Updated Fiddle Example

我正在将 tablesorter 与过滤器小部件一起使用。有人能告诉我如何在 AJAX 请求后更新过滤器吗？正如您在示例中看到的，通过 AJAX 添加额外行后使用过滤器时，表中的所有数据都不会返回。

代码:

$(function(){

  var options = {
    widthFixed : true,
    showProcessing: true,
    headerTemplate : '{content} {icon}', // Add icon for jui theme; new in v2.7!

    widgets: [ 'uitheme', 'zebra', 'stickyHeaders', 'filter' ],

    widgetOptions: {

      stickyHeaders : '',
      stickyHeaders_offset : 0,
      stickyHeaders_cloneId : '-sticky',
      stickyHeaders_addResizeEvent : true,
      stickyHeaders_includeCaption : true,
      stickyHeaders_zIndex : 2,
      stickyHeaders_attachTo : null,
      stickyHeaders_filteredToTop: true,

      zebra   : ["ui-widget-content even", "ui-state-default odd"],
      uitheme : 'jui'
    }
  };

  $(".tablesorter").tablesorter(options);


});

$(document).ready(function() { 
    $('.area button').click(function(){

        var source = $(this).data('feed');

        $.ajax({
    url: source,
    success: function (data) {

        $(data.query.results.json.json).each(function (index, item) {         
          var title = item.title,
              year = item.year, 
              job = item.Job,
              education = item.Education,
              background = item.Background,
              ingredient = item.Ingredient;
              $(".tablesorter tbody").append('<tr style="display:table-row;" class="trremove"><td>'+education+'</td><td>'+background+'</td><td>'+job+'</td><td>'+ingredient+'</td><td>'+year+'</td><td>'+background+'</td><td>'+year+'</td></tr>');

        });
       },
      });
      $("table").trigger("update");            
        var sorting = [[2,1],[0,0]]; 
        $(".tablesorter").trigger("sorton",[sorting]); 
      }); 
     return false; 
 }); 


$('.remove').click(function(){

    $('.trremove').empty();
    $(".tablesorter").trigger("update");
});

HTML:

<button class="remove">Remove</button>
<div class="area"><button>Class B</button></div>
<div class="area"><button>Class C</button></div>
<div class="area"><button>Class D</button></div>

Answer 1

成功代码缺少更新方法 ( updated demo )。

success: function (data) {

    $(data.query.results.json.json).each(function (index, item) {         
      ...
      $(".tablesorter tbody")
        .append('<tr>...</tr>')
        // update the internal cache so filtering will work
        .trigger('update');
    });
   },
  });
