开源鸿蒙 Event Configuration
Event Configuration
You can use event methods to configure events supported by components.
- Example of using a lambda expression to configure the event of a component:
// Counter is a private data variable defined in the component.
Button('add counter')
.onClick(() => {
this.counter += 2
})
- When using an anonymous function expression to configure the event of a component, bind must be used to ensure that the contained components are referenced by this in the function body.
// Counter is a private data variable defined in the component.
Button('add counter')
.onClick(function () {
this.counter += 2
}.bind(this))
- Example of using a component’s member function to configure the event of the component:
myClickHandler(): void {
// do something
}
...
Button('add counter')
.onClick(this.myClickHandler)
