Arkts开发父子组件创建和通信

组件同页面文件的结构相同都加
@Entry和@Component修饰

父组件Parent.ets

import Child from './Child'
@Entry
@Component
struct Parent{

	build(){
		Comlumn(){
			Child({
				toChildData: "我是父参数",
				toChildFun: () => {}
			})
		}
	}

}

子组件 Child.ets

@Entry
@Component
export default struct Child {
	@Props toChildData: string
	@Props toChildFun: () => void
	build(){
		Text(this.toChildData)
			.fontSize(40)
			.fontColor('green')
			.fontWeight(600)
		Button("子组件按钮")
			.type(ButtonType.Normal)
			.onClick(this.toChildFun)

	}
}
