js下拉框：从数组中筛选出匹配的数据

handleChange(val) {
        let obj = {}
        // 遍历数组
        obj = this.options.find(item => {
          // 筛选出匹配的数据
          return item.id === val
        })
        this.hzid = obj.hzid
        this.projectId = obj.id
        console.log(obj, this.projectId, this.hzid)
      },
