鸿蒙父组件中如何处理子组件内点击事件

在父组件中初始化子组件时，将父组件中定义的方法，传递给子组件，在子组件中调用该方法，类似于变量传递。参考代码如下：

class Model { value: string = '' 
} @Entry 
@Component 
struct EntryComponent { test() { console.log('testTag test in my component'); } build() { Column() { MyComponent({ title: { value: 'Hello World 2' }, count: 7, click: this.test }) //初始化时传递定义的方法 } } 
} @Component 
struct MyComponent { @State title: Model = { value: 'Hello World' } @State count: number = 0 click: () => void = () => { }; private toggle: string = 'Hello World' private increaseBy: number = 1 build() { Column() { Text(`${this.title.value}`).fontSize(30) Button(`Click to increase count=${this.count}`) .margin(20) .onClick(() => { // 修改内部状态变量count this.count += this.increaseBy this.click(); }) } } 
}
