area-select无法初始化往往是数据初始化了，但是Dom并没有更新，所以需要再Dom创建之前进行清空，再渲染对应的Dom
<area-select v-model="selected" :level="2" :data="pcaa" :placeholders="placeholder" type="all" style="white-space:nowrap;" @change="selectAddress" v-if="selectVisiual" />
`this.selectVisiual=false that.selected=[] if(this.timeOUt){ clearTimeout(this.timeOUt) } this.timeOUt= setTimeout(() => {this.selectVisiual = true},0)`
