Blazor - JavaScript/引導動畫和腳本在 blazor 組件中不起作用

Question

我有一個 Blazor 站點，我正在使用一個 HTML 模板，該模板具有 CSS 和 JS 用於樣式設置。

我已將資產導入 wwwroot，並在 _Host.cshtml 文件中對它們進行了引用； 樣式和某些元素似乎正在工作......但是我注意到 javascript 的動畫和其他部分沒有按預期工作......

例如，我有一個手風琴，它不會展開或關閉。

我以 HTML 格式制作了相同的頁面，並將其放入 wwwroot ...當我運行代碼並導航到該頁面時，它似乎工作得很好。 但是在我的 razor 頁面上，它不是...

這是它在.razor組件上

這是我在wwwroot中制作的.html文件

這是代碼...

_Host.cshtml

下午好，

根據我在 Blazor 組件中調用 Javascript 的經驗，需要使用 IJS 運行時。 這是針對此問題的 Microsoft Blazor 文檔：

https://docs.microsoft.com/en-us/aspnet/core/blazor/call-javascript-from-dotnet?view=aspnetcore-5.0

本質上，您使用 IJS 運行時從您的自定義 JS 文檔中調用特定方法。
