Click Effect

You can set the click effect for a component to define how it behaves when clicked.

NOTE

The APIs of this module are supported since API version 10. Updates will be marked with a superscript to indicate their earliest API version.

Attributes

Name	Type	Description
clickEffect	ClickEffect \|null	Click effect of the component. NOTE You can remove the click effect by setting this attribute to undefined or null. Avoid using this attribute in scenarios where the component size dynamically changes. This attribute is not supported when the component cannot trigger a universal event.

ClickEffect

Name	Type	Mandatory	Description
level	ClickEffectLevel	Yes	Click effect of the component. NOTE If level is set to undefined or null, the click effect corresponding to ClickEffectLevel.LIGHT will be used. For details about the zoom ratio, see the description of scale.
scale	number	No	Zoom ratio. This parameter works based on the setting of ClickEffectLevel. NOTE The default value of this parameter varies by the value of level. If level is set to ClickEffectLevel.LIGHT, the default value is 0.90. If level is set to ClickEffectLevel.MIDDLE or ClickEffectLevel.HEAVY, the default value is 0.95. If level is set to undefined or null (both of which evaluate to ClickEffectLevel.LIGHT), the default value is 0.90. If scale is set to undefined or null, the default zoom ratio for the set level will be used.
