alert

Display a simple alert dialog with a title, content, and single button.

Overview

my.alert displays an alert box with customizable title, content, and button text. This is a modal dialog that requires user interaction to dismiss.

Sample Code

my.alert({
  title: 'Tips',
  content: 'Your bill for this month has been released',
  buttonText: 'Show',
  success: () => {
    my.alert({
      title: 'Click "Show"',
    });
  },
});

Usage Notes

The alert is a modal dialog - it blocks interaction with the rest of the Mini Program until dismissed
Default button text is "OK" if buttonText is not specified
Only one button is displayed (use my.confirm for two-button dialogs)
The success callback is triggered when the user taps the button
