使用 ngx-bootstrap 的引导下拉菜单

Question

我会使用以下命令在 angular2 中安装 ngx-bootstrap npm install ngx-bootstrap bootstrap --save

包含在 angular-cli.json 中的以下行

 "../node_modules/bootstrap/dist/css/bootstrap.min.css".

在 app.component.html 中添加以下行

  <div  class="dropdown">
     <a class="pull-right text-center btn btn-setting dropdown-toggle"  data-toggle="dropdown" aria-haspopup="true" aria- expanded="true"><i class="fa fa-cog"></i></a>
     <ul class="dropdown-menu" role="menu" aria-labelledby="menu1">
        <li role="presentation">  <a role="menuitem" tabindex="-1" href="#" data-toggle="modal" data-target="#myModal"><i class="fa fa-cog"></i>Settings</a></li>
     </ul>                                      
  </div>

以上代码不适用于引导下拉菜单 但是下拉菜单不起作用。请帮助我。

我的 package.json 是

你是否在你的 app.module.ts 中添加了这个？？

import { BsDropdownModule } from 'ngx-bootstrap/dropdown'
@NgModule({
  imports: [BsDropdownModule.forRoot(),...]
})
export class AppModule(){}

还将您的 app.component.html 更新为

<div  class="dropdown" dropdown>
    <a dropdownToggle class="pull-right text-center btn btn-setting dropdown-toggle"  data-toggle="dropdown" aria-haspopup="true" aria- expanded="true"><i class="fa fa-cog"></i></a>
    <ul *dropdownMenu class="dropdown-menu" role="menu" aria-labelledby="menu1">
        <li role="presentation">  <a role="menuitem" tabindex="-1" href="#" data-toggle="modal" data-target="#myModal"><i class="fa fa-cog"></i>Settings</a></li>
    </ul>
</div>
