更改角度组件中的活动引导程序选项卡 [英] Change active bootstrap tab inside angular component
问题描述
我一直困扰着这个简单的问题,一遍又一遍地通过SO解决方案似乎并不完全适合我的用例... 我有一个角度组件,其中包含一个模板,其中包含引导导航药丸,这些药丸仅用作此特定屏幕中的选项卡.因此,我有一个搜索"选项卡和一个结果"选项卡,执行搜索之后,我想激活结果"选项卡,但是我无法弄清楚如何从组件中插入引导选项卡.
Hi I have been stuck on what seems like this simple problem for a while going back and forth through SO solutions does not seem to fit my use case exactly... I have an angular component which has a template containing bootstrap nav pills, these are just being used as tabs within this particular screen. So I have a Search tab and a results tab and after performing a search I want to activate the results tab but I can't work out how to hook into the bootstrap tabs from the component.
模板...
<div id="tabs" #tabs>
<ul class="nav nav-pills">
<li class="nav-item">
<a class="nav-link active" href="#search" data-toggle="tab">Search</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#results" data-toggle="tab">Results</a>
</li>
</ul>
<div class="tab-content">
<div class="tab-pane active" id="search">
search screen
<button type="button" (click)="search()">Search</button>
</div>
<div class="tab-pane active" id="results">results screen</div>
</div>
</div>
然后组件就像..
@Component({
selector: 'app-demo',
templateUrl: './demo.component.html'
})
export class DemoComponent implements OnInit {
@ViewChild('tabs') tabs;
search() {
//perform search. then select the results tab in template.
//this.tabs.selectedIndex = ...
}
}
这可能吗?还是我需要使用在组件中配置的其他选项卡.预先非常感谢.
Is this possible? or do I need to be using a different flavour of tabs which are configured in the component. Many thanks in advance.
推荐答案
使用activeTab
跟踪哪个选项卡处于活动状态,并使用ngClass
来应用.active
类
Keep a track of which tab is active using activeTab
and use ngClass
to apply .active
class
component.html
<div id="tabs" #tabs>
<ul class="nav nav-pills">
<li class="nav-item">
<a class="nav-link active" href="#search" [ngClass]="{ 'active':activeTab==='search'}" (click)="search('search')"
data-toggle="tab">Search</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#results" [ngClass]="{ 'active':activeTab==='result'}" data-toggle="tab"
(click)="result('result')">Results</a>
</li>
</ul>
<div class="tab-content">
<div class="tab-pane" id="search" [ngClass]="{ 'active':activeTab==='search'}">
search screen
<button type="button" (click)="search('result')">Search</button>
</div>
<div class="tab-pane" id="results" [ngClass]="{ 'active':activeTab==='result'}">results screen</div>
</div>
</div>
component.ts
activeTab = 'search';
search(activeTab){
this.activeTab = activeTab;
}
result(activeTab){
this.activeTab = activeTab;
}
