javascript - JavaScript错误:对象不支持属性进度栏

您好，我在JavaScript jquery progressbar上遇到问题。错误是该对象不支持属性进度栏。我已经尝试了其他帖子中的所有问题，但都没有问题:(

我还检查了jquery文件是否正确加载。

在底部的Create.cshtml中是进度条的代码。

这是Create.cshtml

@model ContosoTelephonebookContext.TelephoneBook

@{
    ViewBag.Title = "Create";
}

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

<h2>Create</h2>

@using (Html.BeginForm("Create", "TelephoneBook", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">
        <h4>Ad</h4>
        <hr />

感谢您的支持

现在，我创建了一个mvce，以便更轻松地分析问题。

我创建了一个空的MVC Web项目，仅添加了所需的功能

这是_layout.cshtml

<!DOCTYPE html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <meta charset="utf-8" />

    @Scripts.Render("~/Scripts/jquery-ui-1.12.1.min.js")
</head>
<body>
    <div class="navbar navbar-inverse navbar-fixed-top">
        <div class="container">

                </button>
                @Html.ActionLink("Anwendungsname", "Index", "Home", new { area = "" }, new { @class = "navbar-brand" })
            </div>

                    <li>@Html.ActionLink("Info", "About", "Home")</li>
                    <li>@Html.ActionLink("Kontakt", "Contact", "Home")</li>
                    <li>@Html.ActionLink("test", "Index", "Test")</li>
                </ul>
            </div>
        </div>
    </div>
    <div class="container body-content">
        @RenderBody()

        <footer>
            <p>&copy; @DateTime.Now.Year - Meine ASP.NET-Anwendung</p>
        </footer>
    </div>

    @Scripts.Render("~/bundles/jquery")
    @Scripts.Render("~/bundles/bootstrap")
    @RenderSection("scripts", required: false)
</body>
</html>

还有test.cshtml

@{
    ViewBag.Title = "Test";
}

<div id="progressbar"></div>

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")

    <script>
        $(function() {
            $("#progressbar").progressbar({
                value: 37
            });
        });
    </script>

}

我再次遇到相同的错误

您好，谢谢您的解决方案。这是完整的解决方案，它现在如何工作。我将正确的版本添加到bundleconfig类中。

using System.Web;
using System.Web.Optimization;

namespace WebApplication1
{
    public class BundleConfig
    {
        // For more information on bundling, visit https://go.microsoft.com/fwlink/?LinkId=301862
        public static void RegisterBundles(BundleCollection bundles)
        {
            bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                        "~/Scripts/jquery-3.2.1.min.js",
                        "~/Scripts/jquery-ui-1.12.1.min.js"));

            bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                        "~/Scripts/jquery.validate*"));

            // Verwenden Sie die Entwicklungsversion von Modernizr zum Entwickeln und Erweitern Ihrer Kenntnisse. Wenn Sie dann
            // ready for production, use the build tool at https://modernizr.com to pick only the tests you need.
            bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                        "~/Scripts/modernizr-*"));

            bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
                      "~/Scripts/bootstrap.js",
                      "~/Scripts/respond.js"));

            bundles.Add(new StyleBundle("~/Content/css").Include(
                      "~/Content/bootstrap.css",
                      "~/Content/site.css",
                      "~/Content/themes/base/progressbar.css",
                      "~/Content/themes/base/jquery-ui.min.css"));
        }
    }
}

最佳答案

问题是加载了两个版本的jQuery。

在此加载一个版本：

@Scripts.Render("~/Scripts/jquery-1.12.4.min.js")

此处加载了另一个版本：

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

一种快速的解决方案是仅将以后的调用替换为您的代码。因此，将第二个示例中的行替换为其他代码（然后将其删除），以使_Layout.cshtml的结尾看起来像这样：

    @Scripts.Render("~/Scripts/jquery-3.2.1.min.js")
    @Scripts.Render("~/Scripts/jquery-ui-1.12.1.min.js")
    @Scripts.Render("~/bundles/bootstrap")
    @RenderSection("scripts", required: false)
</body>
</html>

更好的解决方案是实际更改BundleConfig.RegisterBundles中的代码，以便通过捆绑机制将要使用的jquery版本和jquery ui一起加载。

还要注意，要使进度条正常工作，还需要包括jQuery ui一部分的CSS文件。

关于javascript - JavaScript错误:对象不支持属性进度栏，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/48130019/
