< area-select type= 'all' :placeholders=" placeholders" :level=' 2' v-model=" send_search_form. selected" :data=" pcaa" > </ area-select > // 三級聯動 import { AreaSelect } from "vue-area-linkage"; import AreaData from "area-data"; import { pca, pcaa } from "area-data"; export default { component: { AreaSelect: AreaSelect }, data() { return { pca: pca, pcaa: pcaa, placeholders: [ " ", " ", " "],       send_search_form: { orderCode: "", itemName: "", orderTime: [], consigneeName: "", state: "", selected: [] }, }, }
