子组件:
<template>
<div class="app">
<input @click="sendMsg" type="button" value="给父组件传递值">
</div>
</template>
<script>
export default {
data () {
return {
//将msg传递给父组件
msg: "我是子组件的msg",
}
},
methods:{
sendMsg(){
//func: 是父组件指定的传数据绑定的函数,this.msg:子组件给父组件传递的数据
this.$emit(‘func‘,this.msg)
}
}
}
</script>
子组件通过this.$emit()的方式将值传递给父组件
注意:这里的func是父组件中绑定的函数名
父组件:
<template>
<div class="app">
<child @func="getMsgFormSon"></child>
</div>
</template>
<script>
import child from ‘./child.vue‘
export default {
data () {
return {
msgFormSon: "this is msg"
}
},
components:{
child,
},
methods:{
getMsgFormSon(data){
this.msgFormSon = data
console.log(this.msgFormSon)
}
}
}
</script>
好了,so easy!
