[英]ngx-bootstrap dropdown not opening in Angular 5 project
I know this question has been asked for many different angular/ngx-bootstrap configurations but as I could not find any helpful answer yet, I decided to open this question. 我知道这个问题已被要求用于许多不同的角度/ ngx-bootstrap配置,但由于我找不到任何有用的答案,我决定打开这个问题。
I am trying to integrate a bootstrap dropdown component using ngx-boostrap: 我正在尝试使用ngx-boostrap集成一个bootstrap下拉组件:
package.json 的package.json
"ngx-bootstrap": "^2.0.2",
In the head of my index.html 在我的index.html的头部
link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"
link href =“https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"rel =”stylesheet“
In my app.module.ts 在我的app.module.ts中
import { BsDropdownModule } from 'ngx-bootstrap';
@NgModule({
declarations: [
AppComponent
],
imports: [
...,
BsDropdownModule.forRoot()
],
providers: [...],
bootstrap: [AppComponent]
})
Then I have a submodule where I try to load the dropdown : 然后我有一个子模块,我尝试加载下拉列表:
submodule.component.html submodule.component.html
<div class="btn-group" dropdown>
<button dropdownToggle type="button" class="btn btn-primary dropdown-toggle">
Button dropdown <span class="caret"></span>
</button>
<ul *dropdownMenu class="dropdown-menu" role="menu">
<li role="menuitem"><a class="dropdown-item" href="#">Action</a></li>
<li role="menuitem"><a class="dropdown-item" href="#">Another action</a></li>
<li role="menuitem"><a class="dropdown-item" href="#">Something else here</a></li>
<li class="divider dropdown-divider"></li>
<li role="menuitem"><a class="dropdown-item" href="#">Separated link</a>
</li>
</ul>
</div>
The dropdown button shows up, but nothing happens when I click it. 下拉按钮显示,但单击它时没有任何反应。 I checked the DOM using the inspector and the content of the dropdown is still empty.
我使用检查器检查了DOM,下拉列表的内容仍为空。
What can I do to make this dropdown work ? 我该怎么做才能使这个下拉列表工作?
EDIT 编辑
I have no idea how, but after playing around with the imports it ended up working. 我不知道怎么做,但在玩完进口之后它最终起作用了。
I moved back the import of BsDropdownModule in my submodule (which was not working in the begining) and it worked. 我在我的子模块中移回了BsDropdownModule的导入(它在开始时没有工作)并且它有效。 I guess I made a silly mistake by the time I opened this question but I can't find what.
当我打开这个问题时,我想我犯了一个愚蠢的错误,但我找不到什么。 I leave this open in case it may help someone...
我保持开放,以防有人帮助...
Did you tell your button to actually show the dropdown? 您是否告诉您的按钮实际显示下拉列表? You need an [isOpen]="whatever", and then maybe another button, service, link, whatever where you toggle that
whatever
variable, like in the example here . 你需要一个[isOpen] =“whatever”,然后可能是另一个按钮,服务,链接,无论你在哪里切换
whatever
变量,就像这里的例子一样。
希望你正确使用selector: 'demo-dropdown-basic'
将你的component.ts包含在父组件的html中,如<demo-dropdown-basic></demo-dropdown-basic>
