全屏模态转场方式

全屏模态转场

通过bindContentCover属性为组件绑定全屏模态页面，在组件插入和删除时可通过设置转场参数ModalTransition显示过渡动效。

说明：

从API Version 10开始支持。后续版本如有新增内容，则采用上角标单独标记该内容的起始版本。不支持横竖屏切换。

属性

名称	参数	参数描述
bindContentCover	isShow: boolean, builder: [CustomBuilder], options?: [ContentCoverOptions]	给组件绑定全屏模态页面，点击后显示模态页面。模态页面内容自定义，显示方式可设置无动画过渡，上下切换过渡以及透明渐变过渡方式。 isShow: 是否显示全屏模态页面。从API version 10开始，该参数支持[$$]双向绑定变量 builder: 配置全屏模态页面内容。 options: 配置全屏模态页面的可选属性。

ContentCoverOptions

名称	类型	必填	描述
modalTransition	[ModalTransition]	否	全屏模态页面的转场方式。
backgroundColor	[ResourceColor]	否	全屏模态页面的背板颜色。
onAppear	() => void	否	全屏模态页面显示回调函数。
onDisappear	() => void	否	全屏模态页面回退回调函数。
