vue单个组件实现无限层级多选菜单功能

if (this.createSwitch) {
let i = this.$store.state.checkList.indexOf(this.item.menuId)
console.log(!this.item.list)
console.log('-----------------------初始化')
if (!this.item.list) {
if (i > -1) {
this.selectedState = 'all'
this.selected = true
} else {
this.selectedState = 'null'
this.selected = false
}

let data = {
id: this.item.menuId,
selectedState: this.selectedState,
originInfo: 'create'
}
this.$emit('changeToPar', data)
this.originInfo = 'this'
}
this.createSwitch = false
}
console.log(this.state)
console.log('----------------created')
},
updated () {
console.log('-------updated=======')
let i = this.$store.state.checkList.indexOf(this.item.menuId)
console.log(!this.item.list)
console.log('-----------------------初始化')
if (!this.item.list) {
if (i > -1) {
this.selectedState = 'all'
this.selected = true
} else {
this.selectedState = 'null'
this.selected = false
}

let data = {
id: this.item.menuId,
selectedState: this.selectedState,
originInfo: 'parent'
}
this.$emit('changeToPar', data)
this.originInfo = 'this'
}
},
mounted () {
console.log('=========mounted-----')
}
}
</script>

调用 orgList带有层级的json数组

<w-tree v-for="o of orgList" :item="o" :level="0" :key="o.key"></w-tree>
