DialogV2

The dialog box is a modal window that commands attention while retaining the current context. It is frequently used to draw the user's attention to vital information or prompt the user to complete a specific task. As all modal windows, this component requires the user to interact before exiting.

This component is implemented based on state management V2. Compared with state management V1, V2 offers a higher level of observation and management over data objects beyond the component level. You can now more easily manage dialog box data and states with greater flexibility, leading to faster UI updates.

NOTE

This component is supported since API version 18. Updates will be marked with a superscript to indicate their earliest API version.
