尝试使用两个有界日期选择器按日期范围实现 DataTables 过滤器。
我在 SO 看到了几个类似的问题，但没有一个有答案对我有用。
到目前为止，我设法实现了界面元素，但不知道如何将它们组合在一起以进一步进行。感谢您的帮助。

我对您的代码做了一些修改。请参阅下面 JavaScript 片段中的注释，其中大部分位于底部，在您的 var myDataTable = $('#staff').DataTable() 声明下:
// I changed some of the start_date values to be more recent, just for testing.
var myTableData = [{

// I instantiate the two datepickers here, instead of all at once like before.
// I also changed the dateFormat to match the format of the dates in the data table.
$("#startdate").datepicker({
"dateFormat": "yy/mm/dd",
"onSelect": function(date) { // This handler kicks off the filtering.
minDateFilter = new Date(date).getTime();
myDataTable.draw(); // Redraw the table with the filtered data.
}
}).keyup(function() {
minDateFilter = new Date(this.value).getTime();
myDataTable.draw();

maxDateFilter = new Date(date).getTime();

// The below code actually does the date filtering.
minDateFilter = "";
maxDateFilter = "";
$.fn.dataTableExt.afnFiltering.push(

return false;

<table id="staff"></table>我还删除了“过滤器”按钮，因为在此实现中不需要它。当您从日期选择器中选择一个日期时，表格应该会自动更新。
