【中文标题】DataTables+Datepicker 按日期范围过滤表格【英文标题】：DataTables+Datepicker filter table by date range 【发布时间】：2019-07-08 13:38:59 【问题描述】：

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 上看到的类似问题很少，但没有一个对我有用。

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。任何帮助表示赞赏。

var myTableData = 
  [

我对您的代码做了一些修改。请参阅下面 JavaScript sn-p 中的 cmets，其中大部分位于底部，在您的 var myDataTable = $('#staff').DataTable() 声明下：

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。

您的（稍作修改）示例具有一定的附加值（独立于时区、有限的年份范围、有界的日期选择器）：

【讨论】：

如果日期在数据表中为yyyy-mm-dd h:i:s 格式，我需要仅使用yyyy-mm-dd 进行搜索，而在数据表中显示格式为yyyy-mm-dd h:i:s 时如何执行此操作？任何建议都会有很大帮助。提前致谢。 @Curr195 我省略了 yymmddUTC 函数的使用，并使用@androidNoobie 的方法来获取时间格式与getTime() 代替您的日期过滤，因为我的日期时间为yy-mm-dd h:i:s 格式我遇到了一些困难无论如何，一开始@Cur195 和@AndroidNoobie 的回答都有助于完成工作。非常感谢 有一件事，在 chrome 中，日期选择器的输入字段显示以前选择的日期，如下拉列表，这很烦人，有什么提示可以解决这个问题吗？另外，我如何在过滤一次后取消选择日期并返回上一个完整列表？ （对不起，如果这很烦人，但如果这与这个答案无关，会发布一个不同的问题。）【参考方案3】：

您必须添加此代码部分以获取日期范围和雇用日期。

    $(document).ready(function()
     $.fn.dataTable.ext.search.push(
     function (settings, data, dataIndex) 
        var min = $('#startdate').datepicker("getDate");
        var max = $('#enddate').datepicker("getDate");
        var hireDate = new Date(data[3]);
        if (min == null && max == null)  return true; 
        if (min == null && hireDate <= max)  return true;
        if(max == null && hireDate >= min) return true;
        if (hireDate <= max && hireDate >= min)  return true; 
        return false;
    
    );
    );

而且你必须为你的按钮点击事件。

$("#filter").click(function () 

    var myDataTable = $('#staff').DataTable();
        myDataTable.draw();
);

第一部分获取日期，第二部分再次绘制数据表。
