無法使用Ajax調用更新DataTable的主體

Question

我有一個DataTable，我試圖通過和ajax調用加載數據，但第一行數據總是說：

“表格中沒有數據”

但在它下面包含了加載的ajax數據。 如何刪除No數據行並將ajax數據加載到該位置？

代碼如下：

<div class="box-body">
  <table id="changeTicketsTable" class="table table-bordered table-striped">
    <thead>
      <tr>
        <th>Ticket Number</th>
        <th>Description</th>
        <th>Risk</th>
        <th>Primary CI</th>
        <th>State</th>
        <th>Planned Start Date</th>
        <th>Actual Start Date</th>
        <th>Actual End Date</th>
        <th>Affected Partners</th>
      </tr>
    </thead>
    <tbody>  

    </tbody>
    <tfoot>
      <tr>
        <th>Ticket Number</th>
        <th>Description</th>
        <th>Risk</th>
        <th>Primary CI</th>
        <th>State</th>
        <th>Planned Start Date</th>
        <th>Actual Start Date</th>
        <th>Actual End Date</th>
        <th>Affected Partners</th>
      </tr>
    </tfoot>
  </table>
</div>

DataTable的實現：

<script>
    getChangeTicketInformation();
    $('#changeTicketsTable').DataTable({
      "pageLength": 5,
      'paging'      : true,
      'lengthChange': true,
      'searching'   : false,
      'ordering'    : true,
      'info'        : true,
      'autoWidth'   : false
    });
  })
</script>

用於進行Ajax調用的Javascript：

function getChangeTicketInformation(){
  $.ajax({
     type: "GET",
     url: "../../get_change_ticket_info",
      success: function(data) {
        $.each(data, function (i, item) {
         $('#changeTicketsTable').find('tbody').append(
            '<tr>' +
            '<td>' + item.number + '</td>' +
            '<td>' + item.short_description + '</td>' +
            '<td>' + item.risk + '</td>' +
            '<td>' + item.cmdb_ci_display_value + '</td>' +
            '<td>' + item.state + '</td>' +
            '<td>' + item.start_date + '</td>' +
            '<td>' + item.work_start + '</td>' +
            '<td>' + item.work_end + '</td>' +
            '<td>' + 'FILL IN' + '</td>'
            + '</tr>');
        });
      }
    });
}

在Chrome中打開開發人員工具，然后在頁面中輸入jquery（也在下面），看看會發生什么。 然后檢查html並查看它是否按預期更新 - 它可能在那里，但可能是隱藏的。

但更好的方法實際上是使用DataTable內置的ajax功能： https ： //datatables.net/examples/ajax/simple.html

$('#changeTicketsTable').find('tbody').append(
            '<tr>' +
            '<td>' + item.number + '</td>' +
            '<td>' + item.short_description + '</td>' +
            '<td>' + item.risk + '</td>' +
            '<td>' + item.cmdb_ci_display_value + '</td>' +
            '<td>' + item.state + '</td>' +
            '<td>' + item.start_date + '</td>' +
            '<td>' + item.work_start + '</td>' +
            '<td>' + item.work_end + '</td>' +
            '<td>' + 'FILL IN' + '</td>'
            + '</tr>');
        });

使用DataTable，您可以使用以下API添加新行：

row.add（） ：向表中添加一個新行。

 function getChangeTicketInformation() { var data = [{number: 1, short_description: '1', risk: 1, cmdb_ci_display_value: 1, state: '1', start_date: '1', work_start: '1', work_end: '1'}, {number: 2, short_description: '2', risk: 2, cmdb_ci_display_value: 2, state: '2', start_date: '2', work_start: '2', work_end: '2'}, {number: 3, short_description: '3', risk: 3, cmdb_ci_display_value: 3, state: '3', start_date: '3', work_start: '3', work_end: '3'}]; //$.ajax({ //type: "GET", //url: "../../get_change_ticket_info", //success: function (data) { var dti = $('#changeTicketsTable').DataTable(); $.each(data, function (i, item) { dti.row.add([ item.number, item.short_description, item.risk, item.cmdb_ci_display_value, item.state, item.start_date, item.work_start, item.work_end, 'FILL IN' ]).draw(false); }); //} //}); } $('#changeTicketsTable').DataTable({ "pageLength": 5, 'paging': true, 'lengthChange': true, 'searching': false, 'ordering': true, 'info': true, 'autoWidth': false }) getChangeTicketInformation();

我可以給你一個簡單的例子來說明你的ajax url中<tbody id='table_tbody_id'></tbody>數組響應，並將它們設置為以下make <tbody id='table_tbody_id'></tbody>和

試試這個吧

function getChangeTicketInformation() {
$.ajax({
    type: "GET",
    url: "../../get_change_ticket_info",
    success: function (data) {

        for (let i in data) {
            let item = data[i];
            let number = item[0];
            let short_description = item[1];
            let risk = item[2];
            let cmdb_ci_display_value = item[3];
            let state = item[4];
            let start_date = item[5];
            let work_start = item[6];
            let work_end = item[7];

            let tableRow = "<tr>\n" +
                "                        <td> " + number + "</td>\n" +
                "                        <td> " + short_description + "</td>\n" +
                "                        <td> " + risk + "</td>\n" +
                "                        <td> " + cmdb_ci_display_value + "</td>\n" +
                "                        <td> " + state + "</td>\n" +
                "                        <td> " + start_date + "</td>\n" +
                "                        <td> " + work_start + "</td>\n" +
                "                        <td> " + work_end + "</td>\n" +
                "                        <td> " + 'FILL IN' + "</td>\n" +
                "                    </tr>";

            $('#table_tbody_id').append(tableRow);
        }

    }
});
}

和通話方法

getChangeTicketInformation();
