v-alert コンポーネントは重要な情報をユーザーに伝える際に使用します。 success、info、warning そして error の4つのバリエーションを備えています。 これらにはそれぞれ異なるアクションを表すデフォルトのアイコンが設定されており、必要に応じて変更が可能です。
The type prop provides 4 default
v-alert styles: success, info, warning, and error. Each of these styles provide a default icon and color. The default colors can be configured globally by customizing Vuetify's theme.
The border prop adds a simple border to one of the 4 sides of the alert. This can be combined props like with color, dark, and type to provide unique accents to the alert.
The color-border prop removes the alert background in order to accent the border prop. If a type is set, it will use the types default color. If no color or type is set, the color will default to the inverted color of the applied theme (black for light and white/gray for dark).
The dense prop decreases the height of the alert to create a simple and compact style. When combined with the border prop the border thickness will be decreased to stay consistent with the style.
The dismissible prop adds a close button to the end of the alert component. Clicking this button will set its value to false and effectively hide the alert. You can restore the alert by binding v-model and setting it to true. The close icon automatically has an
aria-label applied that can be changed by modifying the close-label prop or changing close value in your locale. For more information on how to global modify your locale settings, navigate to the Internationalization page.
The icon prop allows you to add an icon to the beginning of the alert component. If a type is provided, this will override the default type icon. Additionally setting the icon prop to false will remove the icon altogether.
The outlined prop inverts the style of an alert, inheriting the currently applied color, applying it to the text and border, and making its background transparent.
The prominent prop provides a more pronounced alert by increasing the height and applying a halo to the icon. When applying both prominent and dense together, the alert will take on the appearance of a normal alert but with the prominent icon effects.
The text prop is a simple alert variant that applies a reduced opacity background of the provided color. Similar to other styled props, text can be combined with other props like dense, prominent, and outlined to create a unique and customized component.
The transition prop allows you to apply a transition to the alert which is viewable when the component hides and shows. For more information, you can checkout any of Vuetify's prebuilt transitions or review how to create your own.
By combining color, dismissible, border, elevation, icon, and color-border props you can create stylish custom alerts such as this twitter notification.
v-alert components are assigned the WAI-ARIA role of alert which denotes that the alert "is a live region with important and usually time-sensitive, information." When using the dismissible prop the close icon will recieve a corresponding
aria-label. This value can be modified by changing either the close-label prop or globally through customizing the Internationalization's default value for the close property.
