jquery DataTable日期范围筛选器显示不正确的结果

我已经实现了DataTable的1.13.1版本,其中包含了按日期范围过滤的功能,并且创建了两个按钮,一个用于继续过滤,另一个用于重置过滤(在datatable网页的指南中,没有这些按钮)。
Date Range Filter Datatable
问题是,当过滤和重置几次(尝试日期选择器中的各种组合)时,有一些结果显示错误。
我不知道我实现的算法是否是我想要的功能(两个按钮)的正确算法。
先谢了。

var minDate, maxDate;

$(function() {
    // Create date inputs
    minDate = new DateTime($('#min'), {
        format: 'DD / MM / YYYY'
    });
      maxDate = new DateTime($('#max'), {
        format: 'DD / MM / YYYY'
    });
 
    // DataTables initialisation
    var table = $('#example').DataTable();

    $("#filter_date").click(function() {

       if ( $("#min").val() !== "" || $("#max").val() !== "") {
            // Custom filtering function which will search data in column four between two values
            $.fn.dataTable.ext.search.push(
                function( settings, data, dataIndex ) {
                    var min = minDate.val();
                    var max = maxDate.val();
                    var date = new Date( data[4] );
             
                    if (
                        ( min === null && max === null ) ||
                        ( min === null && date <= max ) ||
                        ( min <= date   && max === null ) ||
                        ( min <= date   && date <= max )
                    ) {
                        return true;
                    }
                    return false;
                }
            );

            table.draw();
        }
    });

    $("#reset_filter_date").click(function() {

        if ( $("#min").val() !== "" || $("#max").val() !== "" ) {
            $("#min, #max").val("");
            $.fn.dataTable.ext.search = [];
            table.draw();
        }
    });
});

数据表搜索插件允许将一些函数推送到一个函数数组中,该数组将在搜索时执行。
你只需要推你的自定义函数一次...在点击hadler中,只需触发搜索和绘制。
还有......尝试总是使用constlet而不是var。您可以阅读有关它的here

$(function() {
  // Create date inputs
  const minDate = new DateTime($('#min'), {
    format: 'DD / MM / YYYY'
  });
  const maxDate = new DateTime($('#max'), {
    format: 'DD / MM / YYYY'
  });

  // DataTables initialisation
  const table = $('#example').DataTable();

  // Add your custom filter function only once (not at every click)
  $.fn.dataTable.ext.search.push(
    function(settings, data, dataIndex) {
      const min = minDate.val();
      const max = maxDate.val();
      const date = new Date(data[4]);
      console.log(min, max)

      if (
        (min === null && max === null) ||
        (min === null && date <= max) ||
        (min <= date && max === null) ||
        (min <= date && date <= max)
      ) {
        return true;
      }
      return false;
    }
  );

  $("#filter_date").click(function() {
    if ($("#min").val() !== "" || $("#max").val() !== "") {
      
      // search and draw
      table.search()
      table.draw();
    }
  });

  $("#reset_filter_date").click(function() {
  
    // Clear the input values
    $("#min, #max").val("");
    
    // set those null aswell
    minDate.val(null)
    maxDate.val(null)
    
    // search and draw
    table.search()
    table.draw();
  });
});
