Question

我想让用户使用某些控件选择日期时间。为此，我尝试使用Javascript日期时间选择器，我直接从互联网复制和过去，但它无法正常工作。我是从here得到的。

请帮我解决这个问题。有没有其他方式为用户提供此功能？我正在使用ASP.NET C＃。我是javascript以及Jquery的新手。

以下是对javascript功能的调用这里调用函数NewCal（），我通过在该函数中保留警报消息来检查，如上面的代码所示，但是不执行进一步的脚本。

Answer 1

我直接复制和过去互联网[原文]

虽然我没有反对您选择的来源的合法性，但您应该始终牢记互联网充斥着可疑的资源。你应该倾向于建立完善，文档齐全，稳定的图书馆。

如果你有这个选项，我建议使用jQuery UI：

http://jqueryui.com/demos/datepicker/

修改

一个简单的例子，只是为了让你开始：

<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.13/themes/base/jquery-ui.css" /> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.13/jquery-ui.min.js"></script> <script> $(function () { $("#date").datepicker(); }); </script> <input id="date" />

只需将其复制粘贴到.html文件中，然后在浏览器中打开即可。请注意，标记不完整（但它仍然有效）。

Answer 2

这很容易。首先从here下载JQuery UI并将其包含到您的页面中。然后使用以下方法


<scritp type="text/javascript">
(function($){
    $("#datepicker").datepicker({
    showOn: "button",
    buttonImage: "/images/calendar.gif",
    buttonImageOnly: true
    });
})(jQuery);

制作一个textbox，其ID为datapicker

<input type="text" id="datepicker">
