Icons in JavaScript Message control

02 Feb 2023 / 4 minutes to read

This section explains the message with no icons, how to show or hide the close icon and add the custom severity icon to the message.

No Icon

By default, severity icons can be displayed according to the severity types to make it more understandable to the user by visual information rather than text. To hide the severity icons, set the showIcon property to false.

The following example demonstrates the different severity messages without the severity icons.

Custom Icon

By default, the severity icons can be displayed according to the severity type to make it more understandable to the user by visual information rather than text. If the user wants to customize these icons, it can be achieved through the cssClass property.

The following example demonstrates how the default message is rendered with a custom severity icon.

Close Icon

The message can be rendered with or without the close icon. The close icon is used to hide the message, either by manually clicking the close icon or through keyboard interaction.

By default, the close icon is not rendered in the message. To show the close icon, set the showCloseIcon property to true.

In the following example, the messages are rendered with the close icon.
