父子组件动态传参父级 一个按钮的操作editingProject (id) { this.redactBox = true // 控制子级显示消失 this.redactPageBox = false // 控制父级显示消失 this.projectID = id // 传入子级的id console.log('子级 == ', this.redactBox) console.log('父级 == ', this.redactPageBox) console.log('id == ', this.projectID)}打印的结果子级接收id我放在了子级watch里面 我想要在mounted里面用到这个id需要怎么在mounted里面接收， 谢谢！！！export default { props: {redactBox: { type: Boolean, default: false},projectID: String}, data () {return { redactList: [], // 音视频列表 photoList: [] // 图片列表}}, watch: {projectID (newVal) { console.log('watch= this.projectID == ', newVal)}}, mounted () {console.log('mounted = this.projectID ==', this.projectID)}
