Vue3中多个v-model如何绑定，直接上代码,比较符合码农干脆利落的办事风格：
代码语言：javascript复制<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>
</head>
<body>
<div id="app" class="demo">
<p>First name: {{ firstName }}</p>
<p>Last name: {{ lastName }}</p>
<user-name v-model:first-name="firstName" v-model:last-name="lastName"></user-name> <!--多个v-model绑定-->
</div>
<script src="https://unpkg.com/vue@next"></script>
<script>
const app = Vue.createApp({});
const UserName = {
props: {
firstName: String,
lastName: String
},
/* emits: ['update:firstName', 'update:lastName'],*/
template: `
<input
type="text"
:value="firstName"
@input="$emit('update:firstName', $event.target.value)">
<input
type="text"
:value="lastName"
@input="$emit('update:lastName', $event.target.value)">
`
};
const HelloVueApp = {
components: {
UserName,
},
data() {
return {
firstName: 'John',
lastName: 'Doe',
};
},
};
Vue.createApp(HelloVueApp).mount('#app')
</script>
</body>
</html>运行效果如下:
多个v-model的绑定其中最核心的代码:
代码语言：javascript复制@input="$emit('update:firstName', $event.target.value)">
