ion-popover

警告

Popovers in Ionic v5 may collide with the popover feature on newer versions of browsers which can cause Ionic's popovers to not render. We recommend upgrading to the latest version of Ionic to avoid this issue.

A Popover is a dialog that appears on top of the current page. It can be used for anything, but generally it is used for overflow actions that don't fit in the navigation bar.

Presenting

To present a popover, call the present method on a popover instance. In order to position the popover relative to the element clicked, a click event needs to be passed into the options of the present method. If the event is not passed, the popover will be positioned in the center of the viewport.

Customization

Popover uses scoped encapsulation, which means it will automatically scope its CSS by appending each of the styles with an additional class at runtime. Overriding scoped selectors in CSS requires a higher specificity selector.

We recommend passing a custom class to cssClass in the create method and using that to add custom styles to the host and inner elements. This property can also accept multiple classes separated by spaces. View the Usage section for an example of how to pass a class using cssClass.

/* DOES NOT WORK - not specific enough */
.popover-content {
background: #222;
}

/* Works - pass "my-custom-class" in cssClass to increase specificity */
.my-custom-class .popover-content {
background: #222;
}

Any of the defined CSS Custom Properties can be used to style the Popover without needing to target individual elements:

.my-custom-class {
--background: #222;
}

If you are building an Ionic Angular app, the styles need to be added to a global stylesheet file. Read Style Placement in the Angular section below for more information.

Usage

import { Component } from '@angular/core';
import { PopoverController } from '@ionic/angular';
import { PopoverComponent } from '../../component/popover/popover.component';

@Component({
selector: 'popover-example',
templateUrl: 'popover-example.html',
styleUrls: ['./popover-example.css'],
})
export class PopoverExample {
constructor(public popoverController: PopoverController) {}

async presentPopover(ev: any) {
const popover = await this.popoverController.create({
component: PopoverComponent,
cssClass: 'my-custom-class',
event: ev,
translucent: true,
});
await popover.present();

const { role } = await popover.onDidDismiss();
console.log('onDidDismiss resolved with role', role);
}
}

Style Placement

In Angular, the CSS of a specific page is scoped only to elements of that page. Even though the Popover can be presented from within a page, the ion-popover element is appended outside of the current page. This means that any custom styles need to go in a global stylesheet file. In an Ionic Angular starter this can be the src/global.scss file or you can register a new global style file by adding to the styles build option in angular.json.
