我有一个带有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,它具有多行,但是当我按下“锁”列的过滤器时,它应该根据“锁2”列过滤图标,但是它显示一行,同时包含图标和“-”符号,并且'Lock2'的值消失,其他字段由td标记内的字符串填充:Vehicle,Serial和Power。
我究竟做错了什么?
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: "-"
});
最佳答案
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 ) {

return (isNaN(data)) ? -1 : +data;

}]
});
好的,以上所述,您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列绑定到同一数据项,因此,由于我在columnDef选项中指定了自定义渲染器,因此对任一列的排序都将基于数字“ Lock”值进行排序。
我编码了这个百叶窗,尽管如此,希望它能开箱即用。
还要注意,我将您的选项参数从传统定义更改为当前的1.10定义。大多数旧式参数名称已被弃用,因此除非您希望在以后的版本中头痛,否则不安全使用。
让我知道是否可行。
