ion-alert
Alertは、ユーザーに情報を提示したり、Inputを使用してユーザーから情報を収集したりするダイアログです。Alertはアプリのコンテンツの上に表示され、アプリの利用を再開する前にユーザーが手動で破棄する必要があります。 オプションに
header, subHeader と
message を持つことができます。
Buttons
buttons の配列には、各buttonの
text のプロパティと、オプションで
handler を利用することができます。
handler が false を返した場合、buttonがクリックされてもAlertは自動的に解除されません。すべての
buttons は、左から右にボタン配列に追加された順序で表示されます。 Note: 一番右のボタン(配列の最後の1つ)がメインボタンです。
Optionally, a
role property can be added to a button, such as
cancel. If a
cancel role is on one of the buttons, then if the alert is dismissed by tapping the backdrop, then it will fire the handler from the button with a cancel role.
Inputs
Alertには、複数の異なるInputを含めることもでき、そのデータをアプリで受け取ることができます。 Inputはユーザーに情報の入力を促す簡単な方法として使用できます。Radios, checkboxes と text inputs textarea はすべて利用できますが、これらを混ぜて利用することはできません。例えば、Alertはすべてbutton Inputであったり、すべてcheckboxでのInputを持つことはできますが、同一のAlertにradioとcheckbox Inputを混ぜることはできません。ただし、"text" Inputでは、
url, email,
text などの複数のtypeを混ぜて利用することはできます。 Alertのガイドラインに収まらない複雑なForm UIが必要な場合は、代わりにModal内でFormを構築することをお勧めします。
Customization
Alert 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
cssClass.
/* DOES NOT WORK - not specific enough */
.alert-wrapper {
background: #e5e5e5;
}
/* Works - pass "my-custom-class" in cssClass to increase specificity */
.my-custom-class .alert-wrapper {
background: #e5e5e5;
}CopyCopied
Any of the defined
.my-custom-class {
--background: #e5e5e5;
}CopyCopied
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.

Style Placement
In Angular, the CSS of a specific page is scoped only to elements of that page. Even though the Alert can be presented from within a page, the
ion-alert 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.
