Question

好的，我有一个像

这样的功能

因此，当调用此函数时，会发出AJAX请求但是如果我再次调用相同的函数。当前请求已完成但前一次调用未被终止。我希望数据表能够杀死任何先前的调用并仅运行最新的调用。

我不知道该怎么做。

Answer 1

这就是我使用DataTables 1.10.16
的方法

var table = $('#table').DataTable({
    ajax: {
        url: '/datatable',
        type: 'POST',
        beforeSend: function() {
            if (table.hasOwnProperty('settings')) {
                table.settings()[0].jqXHR.abort();
            }
        }
    }
});

我认为这些主题会有所帮助：

Abort previous ajax call in datatables 1.10

How can I stop all the currently ongoing Ajax queries that DataTables instance have started?

看起来你可以在你的函数的第一行添加这样的东西：

function load(id) {
    if($('#videos_list').DataTable().settings.jqXHR) {
        $('#videos_list').DataTable().settings.jqXHR.abort()
    }
    $("#table_wrapper").mask("");
    etc...

Answer 3

以下对我有用......

var elTable = jQuery('table#myDataTable');
var oTable = elTable.DataTable();
oTable.context[0].jqXHR.abort()

这可能会帮助某人

        preDrawCallback: function(settings) {
            if ($.fn.DataTable.isDataTable('#table')) {
                var dt = $('#table').DataTable();

                //Abort previous ajax request if it is still in process.
                var settings = dt.settings();
                if (settings[0].jqXHR) {
                    settings[0].jqXHR.abort();
                }
            }
        }

我有数据表 1.10.5 。它的工作。

我也做了如下调用延迟。

           if ($.fn.DataTable.isDataTable('#table')) {
               var dt = $('#table').DataTable();

               //Abort previous ajax request if it is still in process.
               var settings = dt.settings();
               if (settings[0].jqXHR) {
                   settings[0].jqXHR.abort();
               }
           }
       }
