I have a child component that accepts a props ( data ), and the parent component is passed to the child component.
parent component uses:
<template>
<sub-component :data="sub_data"></sub-component>
</template>in subcomponents:
export default{
props: {
data: {
type: Array,
required: true
}
}
}
excuse me, after the sub_data data in the parent component is modified, will the data of the child component change accordingly,
if I succeed in the test myself, it will change.
parent component:
<delete-selection-btn :selection="selection" ></delete-selection-btn>
Sub-component:
<script>
export default{
props:{
selection: {
type: Array,
required: true
}
}
,
data(){
return {
msg: 'hello vue'
}
},
methods: {
delete_selection_proptip_click(){
console.log(this.selection)
}
}
}
