Question

我正在使用Tomcat中的一个项目，我遇到了一个JavaScript文件问题。我正在尝试使用pickadate.js，当我将所有内容都放在HTML文件中时，一切正常，但是当我编写一个读取html文件并将其打印到响应编写器的servlet时，日期选择器不起作用，我得到了在Web控制台中出现以下JavaScript错误：

10:37:53.100 SyntaxError: missing : in conditional expression picker.js:349
10:37:53.102 SyntaxError: missing ; before statement picker.date.js:293
10:37:53.106 TypeError: $(...).pickadate is not a function AdminBlackout:24

以下是我在servlet中阅读的HTML文件：

<!doctype html>
<html>
    <head>

        <meta charset="utf-8">

        <script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>

        <link rel="stylesheet" href="pickadate.js-3.4.0/tests/dev/style.css">
        <link rel="stylesheet" href="pickadate.js-3.4.0/lib/themes/default.css">
        <link rel="stylesheet" href="pickadate.js-3.4.0/lib/themes/default.date.css">

        <script src="pickadate.js-3.4.0/lib/picker.js"></script>
        <script src="pickadate.js-3.4.0/lib/picker.date.js"></script>
        <script src="pickadate.js-3.4.0/lib/legacy.js"></script>

    </head> 

    <body> 
        <input class="datepicker" type="text">

        <script type="text/javascript">
            $('.datepicker').pickadate();
        </script>

    </body>

</html>

servlet生成的源与上面完全相同。当我直接在浏览器中加载html文件时，一切正常，没有JavaScript错误。 pickadate.js-3.4.0文件夹位于我的webapp的根目录中。如果有人对如何解决这个问题有任何想法，我将不胜感激。

Answer 1

这听起来像编码问题：

当Java读取文件时，请考虑它假定文件的编码是系统的默认编码。在Windows中，这意味着您使用的是ISO-8859-1的变体，而不是UTF-8，浏览器的默认编码是什么。 servlet如何读取文件？请求使用的编码是什么？

JavaScript文件与servlet无法正常工作
