vue3中emit('update:modelValue')使用简单示例

<template>
  <TestCom v-model="test1" v-model:test2="test2"></TestCom>
  <h1>{{test1}}测试1</h1>
  <h1>{{test2}}测试2</h1>
</template>

<script setup>
import { ref, reactive } from 'vue'
const test1 = ref('')
const test2 = ref('')
</script>

<template>
	<input v-model="message" @input="changeInfo(message)" />
	<input v-model="message2" @input="changeInfo2(message2)" />
</template>
<script setup>
import { ref, watch } from 'vue';
// 此处引入
const emit = defineEmits(['update:modelValue', 'update:test2'])
const props = defineProps({
	// 父组件 v-model 没有指定参数名，则默认是 modelValue
	modelValue:{ 
		type:String,
		default: 'test'
	},
	test2: {
		type: String,
		default: 'aaa'
	}
})

let message = ref('123')
let message2 = ref('456')
// 因为props.modelValue、props.test2是非引用类型，改变时，需要监听，对响应式数据重新赋值
watch(()=> props.modelValue,() => {message.value = props.modelValue})
watch(()=> props.test2,() => {message2.value = props.test2})
// 数据双向绑定
const changeInfo = (info) => {
	emit('update:modelValue', info)
}
const changeInfo2 = (info2) => {
	emit('update:test2', info2)
}
</script>

<script>
import { ref, watch } from 'vue';
export default {
	props: {
		// 父组件 v-model 没有指定参数名，则默认是 modelValue
		modelValue:{
			type:String,
			default: 'test'
		},
		test2: {
			type: String,
			default: 'aaa'
		}
	},
	setup(props, { emit }) {
		let message = ref('123')
		let message2 = ref('456')
		// 因为props.modelValue、props.test2是非引用类型，改变时，需要监听，对响应式数据重新赋值
		watch(()=> props.modelValue,() => {message.value = props.modelValue})
		watch(()=> props.test2,() => {message2.value = props.test2})
		// 数据双向绑定
		const changeInfo = (info) => {
			emit('update:modelValue', info)
		}
		const changeInfo2 = (info2) => {
			emit('update:test2', info2)
		}
		return {
			message, message2, changeInfo, changeInfo2
		}
	}
}
</script>
