OMIEvent
tsx
import { Component, h } from 'omi'
@tag('my-element')
class MyElement extends Component {
onClick = (evt) => {
alert('Hello Omi!')
}
render() {
return (
<h1 onClick={this.onClick}>Hello, world!</h1>
)
}
}import { Component, h } from 'omi'
@tag('my-element')
class MyElement extends Component {
onClick = (evt) => {
alert('Hello Omi!')
}
render() {
return (
<h1 onClick={this.onClick}>Hello, world!</h1>
)
}
}使用bind装饰器代替箭头函数自动绑定this：
tsx
import { Component, h, bind } from 'omi'
@tag('my-element')
class MyElement extends Component {
@bind
onClick(evt) {
alert('Hello Omi!')
}
render() {
return (
<h1 onClick={this.onClick}>Hello, world!</h1>
)
}
}import { Component, h, bind } from 'omi'
@tag('my-element')
class MyElement extends Component {
@bind
onClick(evt) {
alert('Hello Omi!')
}
render() {
return (
<h1 onClick={this.onClick}>Hello, world!</h1>
)
}
}Custom Event
tsx
@tag('my-element')
class MyElement extends Component {
onClick = (evt) => {
this.fire('my-event', { name: 'abc' })
}
render(props) {
return (
<h1 onClick={this.onClick}>Hello, world!</h1>
)
}
}@tag('my-element')
class MyElement extends Component {
onClick = (evt) => {
this.fire('my-event', { name: 'abc' })
}
render(props) {
return (
<h1 onClick={this.onClick}>Hello, world!</h1>
)
}
}然后在你的自定义元素上绑定事件：
tsx
<my-element onMyEvent={(evt) => { alert(evt.detail.name) }}></my-element><my-element onMyEvent={(evt) => { alert(evt.detail.name) }}></my-element>或者
js
myElement.addEventListener('my-event', (evt) => {})myElement.addEventListener('my-event', (evt) => {})通过 this.fire 触发自定义事件，fire 第一个参数是事件名称，第二个参数是传递的数据。通过 evt.detail 可以获取到传递的数据。
