javascript - 引导模板“切换菜单”按钮在 Angular 中不起作用

问题描述

我将在 Angular 项目中使用这个模板。[ https://startbootstrap.com/previews/simple-sidebar/][1] 我已经将home.component.html中的所有模板代码粘贴了；如代码所示。一切顺利，css 加载完美，与链接中的模板相同。我需要的是“切换菜单”按钮才能工作。我认为这是由于在 HTML 末尾找到的 JS 代码，但是，我不知道如何进行。请你帮助我好吗。[1]：https ://startbootstrap.com/previews/simple-sidebar/

您需要从所述模板安装所有必需的 CSS。请在下面找到完整的代码。

$("#menu-toggle").click(function(e) {
  e.preventDefault();
  $("#wrapper").toggleClass("toggled");
});

对于 Angular - StackBlitz 演示

.html

// use [ngClass] to toggle the class for the div
<div class="d-flex" id="wrapper" [ngClass]="{'toggled': toggled}"></div>

// attach the click 
<button class="btn btn-primary" id="menu-toggle" (click)="onToggle()">Toggle Menu</button>

.ts

toggled = false;

onToggle(){
  this.toggled = !this.toggled;
}
