Question

我有一个数据绑定值的数据表：

<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>

和.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，它有多行，但是当我按下过滤器的列时，锁定＆＃39;它应该根据列＆＃39; Lock2＆＃39;过滤图标。但它显示一行，同时显示两个图标和＆＃34; - ＆＃34;标志和＆＃39; Lock2＆＃39;的价值dissapears和其他字段用td标记内的字符串填充：Vehicle，Serial和Power。

我做错了什么？

修改<！/强>

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);

所有值均为＆＃34; - ＆＃34;当列表应该为空时......

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，以上所有你需要的是一个空表元素。您不再需要在插件将自动创建的HTML中指定“thead”或“tbody”。我将Lock和Lock2列绑定到同一个数据项，因此在任一列上排序将根据数字“Lock”值进行排序，因为我在columnDef选项中指定了自定义渲染器。

我对此进行了编码，但希望它开箱即用。

另请注意，我将选项参数从旧版定义更改为当前1.10定义。不推荐使用大多数旧版参数名称，因此除非您在将来的版本中需要麻烦，否则不能安全使用。

让我知道这是否成功。

编辑：抱歉忘了添加数据绑定。参考：https://datatables.net/manual/data/

带有图标的数据表，而不是基于其他列对列进行排序
