[英]Angular2 ng2-popover hide() is not working
app.module.ts
import { PopoverModule } from 'ng2-popover';
@NgModule({
declarations: [ ...],
imports: [PopoverModule],
providers: []
})
example.html的
<a [popover]="customPopover" [popoverOnHover]="true" [popoverCloseOnMouseOutside]="true" href="www.google.com" (click)="$event.stopPropagation()" target="_blank">{{name}}</a>
<!--Popover content -->
<popover-content #customPopover title="{{name}}" placement="right"
[closeOnClickOutside]="true" [closeOnMouseOutside]="true">
<span class="popoverDesc">{{description}}</span><br /><br />
<a href="{{websiteLink | formatUrl:'url'}}" (click)="$event.stopPropagation()" target="_blank">{{websiteLink | formatUrl:'text'}}</a><br /><br />
<button class="btn btn-secondary popoverBtn" (click)="toggleAddToListModalPopover($event)">Add to list</button>
</popover-content>
example.component.ts
import { PopoverContent } from 'ng2-popover';
@ViewChild('customPopover') customPopover: PopoverContent;
protected toggleAddToListModalPopover(e):void {
this.customPopover.hide();
this.showAddToListModal = !this.showAddToListModal;
e.stopPropagation();
}
我想在模式打開時隱藏彈出窗口。 當我調用“ customPopover.hide()”函數時,它給了我錯誤:
error_handler.js:51 TypeError:無法讀取未定義的屬性“ hide”
在PopoverContent.hide(PopoverContent.js:78)
在“ PopoverContent.js”文件中,有一行this.popover.hide();。 但我不知道如何初始化它。 據我了解,@ViewChild僅將類綁定初始化為#customPopover,即在我的情況下為popover-content。 有人可以給我解決方案初始化“ Popover”嗎?
我使用以下代碼解決了該問題,即在函數中添加“ customPopover”作為參數並調用hide()方法。 我不知道這是否是解決此問題的好方法?
example.html的
<button class="btn btn-secondary popoverBtn" (click)="toggleAddToListModalPopover(customPopover, $event)">Add to list</button>
example.component.ts:
protected toggleAddToListModalPopover(customPopover, e):void {
customPopover.hide();
this.showAddToListModal = !this.showAddToListModal;
e.stopPropagation();
}
我認為在您的情況下, this.customPopover
是未定義的。
您可以通過其他方式隱藏您的popover內容,例如,
<div>
<popover-content #myPopover title="this header can be omitted" placement="right" [closeOnClickOutside]="true">
<b>Very</b> <span style="color: #C21F39">Dynamic</span> <span style="color: #00b3ee">Reusable</span>
<b><i><span style="color: #ffc520">Popover With</span></i></b> <small>Html support</small>. Click outside of this popover and it will be dismissed automatically.
<u (click)="myPopover.hide()">Or click here to close it</u>.
</popover-content>
<button [popover]="myPopover">click this button to see a popover</button>
</div>
看看是否有幫助。
