我的代码是这个样子的：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="DateTimePickQuestion1.WebForm1" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title></title> <!-- 新 Bootstrap 核心 CSS 文件 --> <link rel="stylesheet" href="http://cdn.bootcss.com/bootstrap/3.3.0/css/bootstrap.min.css"> <!-- 可选的Bootstrap主题文件（一般不用引入） --> <link rel="stylesheet" href="http://cdn.bootcss.com/bootstrap/3.3.0/css/bootstrap-theme.min.css"> <!-- jQuery文件。务必在bootstrap.min.js 之前引入 --> <script src="http://cdn.bootcss.com/jquery/1.11.1/jquery.min.js"></script> <!-- 最新的 Bootstrap 核心 JavaScript 文件 --> <script src="http://cdn.bootcss.com/bootstrap/3.3.0/js/bootstrap.min.js"></script> <!-- import datetimepicker js and css --> <script src="js/bootstrap-datetimepicker.js" type="text/javascript"></script> <script src="js/locales/bootstrap-datetimepicker.zh-CN.js" type="text/javascript"></script> <link href="css/bootstrap-datetimepicker.css" rel="stylesheet" type="text/css" /> <!-- my script --> <script type="text/javascript"> $(function () { $("#mySelect").change(function () { $(".form_datetime").datetimepicker('remove'); var type = $("#mySelect").val(); switch (type) { case "month": $('.form_datetime').datetimepicker({ autoclose: true, startView: 'year', minView: 'year', format: 'yyyy-mm' }); break; case "year": $('.form_datetime').datetimepicker({ autoclose: true, startView: 'decade', minView: 'decade', format: 'yyyy' }); break; } //end switch })//end change })//end ready </script></head><body> <div> <select id='mySelect'> <option value='year'>year</option> <option value='month'>month</option> </select> <div class="input-group date form_datetime col-md-2" > <input class="form-control" type="text" /> <span class="input-group-addon"> <span class="glyphicon glyphicon-th"></span> </span> </div> </div></body></html>
你用一下 datetimepicker 的update函数
比如 datetimepicker( 'update', new Date() )
