刷新表时数据表中的重复标题图标

Question

我正在使用 jquery 数据表来显示我从 jsonresponse 获得的数据。 表格的初始显示还可以，但是当我点击刷新并使用时

$('#search-notable-authors').DataTable().destroy();
$('#search-notable-authors').DataTable(

它会重新加载表格，但会按照我点击刷新按钮的次数重复标题图标。

这是完整的jq代码

<script type="text/javascript">
    var $jquery_1_11_3 = jQuery.noConflict(true);
    (function ($) {
        $(document).ready(function () {

                showItemsTable1();

            ajaxPaths = {
                allNotableAuthors:   "{{ path('json_getAllNotableAuthors') }}",

如何在不重复标题图标的情况下解决此问题？

Answer 1

我没有找到问题所在，所以我没有修复它，但我找到了绕过它的解决方案。所以这就是我要做什么，直到我找到更好的东西。

在脚本开始时，我从表头中获取 html，如下所示：

var hdr = $('#search-notable-authors').find('thead').html();

然后在 showItemsTable 我销毁并清空表格

var tableId = $('#search-notable-authors');
itemsTable = $(tableId).DataTable();
itemsTable.destroy();
$(tableId).empty();

然后用table的thead替换html

$('#search-notable-authors').find('thead').html(hdr);

这里是完整的 showItemsTable 代码：

showItemsTable = function () {
                return $.Deferred(function () {
                    var that = this;
                    getItems().done(function (itemsData) {
                        var tableId = $('#search-notable-authors');
                        var header = $(tableId).find('thead').html();
                        itemsTable = $(tableId).DataTable();
                        itemsTable.destroy();
                        $(tableId).empty();

                        itemsTable = $(tableId).DataTable({

                            aLengthMenu: [
                                [25, 50, 100, 200, -1],
                                [25, 50, 100, 200, "All"]
                            ],
                            iDisplayLength: -1,
                            data: itemsData,
                            columns : [
                                DataTables.expandCol,
                                {"data": 'id'},
                                {"data": 'email'},
                                {"data": 'journal'},
                                {"data": 'title'},
                                {"data": 'citation_link'}
                            ]
                        });
                        $('#search-notable-authors').find('thead').html(hdr);
                        that.resolve();
                    });
                });
            },
