ASP.NET MVC Bootstrap 日期选择器错误

Question

我在为某些视图的日期字段实现日期选择器时遇到了一些问题。我得到一个错误：

JavaScript runtime error: Object doesn't support property or method 'datepicker'

这是我的 _Layout 代码，我似乎无法理解为什么这个错误会继续弹出。任何帮助将不胜感激。

<html>
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>@ViewBag.Title - My ASP.NET Application</title>
    @Styles.Render("~/Content/css")
    @Scripts.Render("~/bundles/modernizr")

    <script src="@Url.Content("~/Scripts/jquery-2.1.3.js")"
            type="text/javascript"></script>\
    <script src="@Url.Content("~/Scripts/bootstrap.js")"

            type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/DatePickerReady.js")"
            type="text/javascript"></script> 

    <script>
        $(function () {
            $('.datepicker').datepicker({
                format: 'mm-dd-yyyy'
            });
        });
    </script>

问题可能是您的代码通过调用将 jQuery 和 Bootstrap 添加了两次：

@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/bootstrap")

这是 jQuery 问题的记录原因。添加 jQuery 两次时，我在此代码段中遇到类似的错误。

<html>
<head>
    <title>DatePicker Example</title>
    <link href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css" rel="stylesheet" />
    <script src="https://code.jquery.com/jquery-1.12.4.js"></script>
    <script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
    <script>
        $(function () {
            $("#datep").datepicker();
        });
    </script>
</head>
<body>
    <h3>Click to select a date :</h3>
    <input type="text" id="datep" />
    <script src="https://code.jquery.com/jquery-1.12.4.js">
</body>
</html>

Uncaught TypeError: $(...).datepicker is not a function

只需删除额外的 jQuery 和任何其他重复的库。根据用户 Shyju 的建议，还包括 jQuery UI。

<html>
<head>
    <title>DatePicker Example</title>
    <link href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css" rel="stylesheet" />
    <script src="https://code.jquery.com/jquery-1.12.4.js"></script>
    <script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
    <script>
        $(function () {
            $("#datep").datepicker();
        });
    </script>
</head>
<body>
    <h3>Click to select a date :</h3>
    <input type="text" id="datep" />
</body>
</html>
