bundles.Add(new StyleBundle("~/css/bootstrap").Include(
            "~/assets/css/bootstrap.min.css"
            ));
bundles.Add(new ScriptBundle("~/bundles/jquery").Include(

dafault.cshtml页面(布局页面)

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

为什么在单击链接并在 $ jquery 中生成时没有加载日历，我想我已经正确地给出了代码和脚本。谁能帮我找到解决方案？？

Answer 1

首先，将 $('#datetimepicker1').datetimepicker(); 移动到 $( document ).ready:

<script>
    $( document ).ready(function() {
        $('#datetimepicker1').datetimepicker();
    });
</script>

此外 - 您正在尝试在加载之前使用 JQuery 功能。

在您的 BundleConfig.cs 中，首先包含 JQuery:

bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
            "~/assets/js/jquery.min.js"));
bundles.Add(new StyleBundle("~/css/bootstrap").Include(
            "~/assets/css/bootstrap.min.css"));
...
Other includes
...

然后在您的 dafault.cshtml 页面中，更改呈现顺序并将 bootstrap css 留在最后:

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