JSON.stringfy
JSON.parse
报错：unexpected token u in position 0
if (sessionStorage.getItem(‘houseIdList‘)) { this.formData.houseIds = JSON.parse(sessionStorage.getItem(‘houseIdList‘)).houseIds }
改为
if (sessionStorage.getItem(‘houseIdList‘)) { this.formData.houseIds = JSON.parse(JSON.stringify(sessionStorage.getItem(‘houseIdList‘))).houseIds }
