javascript - 带有图标的数据表不根据其他列对列进行排序

Question

我有一个包含数据绑定(bind)值的数据表:

<table class="table" style="width: 100%;" id="TableC">
   <thead>
      <tr>
         <th>Vehicle</th>
         <th>Serial</th>
         <th>Power</th>
         <th>Lock</th>
         <th>Lock2</th>
      </tr>
    </thead>
    <tbody data-bind="foreach: techlist">
       <tr>
          <td data-bind="text: Vehicle">Vehicle</td>
          <td data-bind="text: Serial">Serial</td>
          <td data-bind="text: Power">Power</td>
          <td>
             <span data-bind="visible: $data.Lock==0" style="font-size:75%" class="fa-stack fa-lg"><i class="fa fa-unlock fa-stack-2x" style="color:#71BF3D"></i></span>
             <span data-bind="visible: $data.Lock==1" style="font-size:75%" class="fa-stack fa-lg"><i class="fa fa-lock fa-stack-2x" style="color:#E74C3C"></i></span>
             <span data-bind="visible:$data.Lock=='-'">-</span>
         </td>
         <td data-bind="text: Lock"></td>
      </tr>
   </tbody>
</table>

及其 .js:

TableC = $("#TableC").DataTable({
    bSortable: true,
    bPaginate: false,
    //"searching": false,
    "info": false,
    "bFilter": false,
    "aoColumnDefs": [
        { targets: 0 },
        { targets: 1 },
        { targets: 2 },
        { targets: 3, orderData: 4 },
        { bSearchable: false, targets: 4 }          
    ]
});

当我第一次加载数据表时，它有多于一行，但是当我按“Lock”列的过滤器时，它应该根据“Lock2”列过滤图标，但它显示一行，同时包含图标和“-”符号和“Lock2”的值消失，其他字段将填充 td 标记内的字符串:Vehicle、Serial 和 Power。

我做错了什么？

编辑!

var displayinfo = [];
displayinfo.push({
                Vehicle: "05", Serial: "925", Power:"30V", 
                Lock: 1
            });
displayinfo.push({
                Vehicle: "06", Serial: "937", Power:"60V", 
                Lock: 0
            });
displayinfo.push({
                Vehicle: "07", Serial: "835", Power:"50V", 
                Lock: 1
            });
techstatuslist(displayinfo);

当列表应该为空时，所有值都带有“-”...

displayinfo.push({
                Vehicle: "-", Serial: "-", Power:"-", 
                Lock: "-"
            });

var displayinfo = [];
displayinfo.push({
                Vehicle: "05", Serial: "925", Power:"30V", 
                Lock: 1
            });
displayinfo.push({
                Vehicle: "06", Serial: "937", Power:"60V", 
                Lock: 0
            });
displayinfo.push({
                Vehicle: "07", Serial: "835", Power:"50V", 
                Lock: 1
            });
TableC = $("#TableC").DataTable({
    data: displayInfo,
    ordering: true,
    paging: false,
    //"searching": false,
    "info": false,
    "searching": false,
    columns: [ 
      { data: "Vehicle", title: "Vehicle" },
      { data: "Serial", title: "Serial" },
      { data: "Power", title: "Power" },
      { data: "Lock", title: "Lock" },
      { data: "Lock", title: "Lock2" }
    ],
    "columnDefs": [ {
       "targets": 3,
       "render": function ( data, type, full, meta ) {
          // If it is rendering the cell contents
          if(type === 'display') {
             switch(data) {
                case 0:
                  return '<span style="font-size:75%" class="fa-stack fa-lg"><i class="fa fa-unlock fa-stack-2x" style="color:#71BF3D"></i></span>';
                case 1:
                  return '<span style="font-size:75%" class="fa-stack fa-lg"><i class="fa fa-lock fa-stack-2x" style="color:#E74C3C"></i></span>';
                default:
                  return '<span>-</span>';
               }
             }

             // Your code implies that lock could be a number or a string ('-')
             // So checking it first to see if we can convert it.  If not then
             // assign -1 as our numeric value.  If we can convert it to a
             // numeric value for sorting and filtering.
             return (isNaN(data)) ? -1 : +data;
          }
      }, 
{
       "targets": 4,
       "render": function ( data, type, full, meta ) {
          // If it is rendering the cell contents
          if(type === 'display') {
              return data;
          }

          // Your code implies that lock could be a number or a string ('-')
          // So checking it first to see if we can convert it.  If not then
          // assign -1 as our numeric value.  If we can convert it to a
          // numeric value for sorting and filtering.
          return (isNaN(data)) ? -1 : +data;
        }
      }]
});

好的，有了上面的内容，您所需要的只是一个空的表格元素。您不再需要在 HTML 中指定“thead”或“tbody”，插件将自动创建它们。我将 Lock 和 Lock2 列绑定(bind)到同一数据项，因此对任一列进行排序都将根据数字“Lock”值进行排序，因为我在 columnDef 选项中指定了自定义渲染器。

我对此进行了盲目编码，希望它能开箱即用。

另请注意，我将您的选项参数从旧定义更改为当前 1.10 定义。大多数旧参数名称已被弃用，因此使用不安全，除非您希望在未来版本中遇到麻烦。

请告诉我这是否有效。
