Jquery Datatable 没有正确地重新排序我的 json

Question

我正在使用：jquery.dataTables.js 来自：https://datatables.net

我希望我的 json 像现在一样显示，但是当在页面中显示时，显示乱序，我希望 json 显示如下：1,2,3,4,5 或者只是顺序是现在数字无关紧要，只要跟随 json。

所以在我的数据表中应该显示如下：eua,china,spain,spain,china。

这是我的奔跑：http://plnkr.co/edit/mQIpriwqOhB59QPYbKHj?p=preview

我有这个 json 文件：

{
  "data": [
    {
      "order": 1, 
      "place": "EUA", 
      "name": "Cannon Morin", 
      "delete": " <i class=\"fa fa-pencil-square\" aria-hidden=\"true\"></i> <i class=\"fa fa-minus-square\" aria-hidden=\"true\"></i>"
    }, 
    {
      "order": 2, 
      "place": "China", 
      "name": "Neva Allison", 
      "delete": " <i class=\"fa fa-pencil-square\" aria-hidden=\"true\"></i> <i class=\"fa fa-minus-square\" aria-hidden=\"true\"></i>"
    }, 
    {
      "order": 3, 
      "place": "Spain", 
      "name": "Rodriquez Gentry", 
      "delete": " <i class=\"fa fa-pencil-square\" aria-hidden=\"true\"></i> <i class=\"fa fa-minus-square\" aria-hidden=\"true\"></i>"
    }, 
    {
      "order": 4, 
      "place": "Spain", 
      "name": "Rodriquez Gentry", 
      "delete": " <i class=\"fa fa-pencil-square\" aria-hidden=\"true\"></i> <i class=\"fa fa-minus-square\" aria-hidden=\"true\"></i>"
    }, 
    {
      "order": 5, 
      "place": "China", 
      "name": "Neva Allison", 
      "delete": " <i class=\"fa fa-pencil-square\" aria-hidden=\"true\"></i> <i class=\"fa fa-minus-square\" aria-hidden=\"true\"></i>"
    }
  ]
}

css:

div.addRow {
  line-height: 45px;
  background-color: #fff;
  padding-left: 10px;
  border-bottom: 1px solid;
  border-top: 1px solid #e5e5e5;
}

html:

   <table id="example" class="display" width="100%" cellspacing="0">
    <thead>
      <tr>
        <th>place</th>
        <th>name</th>

    </thead>
  </table>


  <table id="newRow" style="display:none">

jquery:

 $(document).ready(function() {

      var table;

      $("#example").on("mousedown", "td .fa.fa-minus-square", function(e) {

      $("#example").on('mousedown.edit', "i.fa.fa-pencil-square", function(e) {

        $(this).removeClass().addClass("fa fa-envelope-o");
        var $row = $(this).closest("tr").off("mousedown");
        var $tds = $row.find("td").not(':first').not(':last');

        $.each($tds, function(i, el) {
          var txt = $(this).text();
          $(this).html("").append("<input type='text' value=\"" + txt + "\">");
        });

      });

      $("#example").on('mousedown', "input", function(e) {
        e.stopPropagation();
      });

      $("#example").on('mousedown.save', "i.fa.fa-envelope-o", function(e) {

        var rowHtml = $("#newRow").find("tr")[0].outerHTML
        console.log(rowHtml);
        table.row.add($(rowHtml)).draw();

    });

Answer 1

您已明确按第一列降序排列表格：

    order: [[ 0, "desc" ]],

并且由于您的第一列不是 order 列，因此它没有按您想要的方式排序。

您的order 列列在第 3 位，因此从零开始的数字为 2，因此您应该这样做：

    order: [[ 2, "asc" ]],

Answer 2

只需更改初始化中的顺序即可。即顺序：[[ 2, "asc" ]],

完整代码如下

   table = $('#example').DataTable({
    ajax: url,
    order: [[ 2, "asc" ]],
    rowReorder: {
      dataSrc: 'place',
      selector: 'tr'
    },
    columns: [{
      data: 'place'
    }, {
      data: 'name'
    }, {
      data: 'order'
    }, {
      data: 'delete'
    }]
  });
