vue js事件方法调用api并返回值

// 确认
confirm(id) {
  if (this.isEdit && this.form.list !== undefined && this.form.list.length <= 0) {
    this.$notify({
      title: '表身为空时不能确认',
      type: 'error'
    })
  } else {
    this.confirmLoading = true
    inConfirm(id).then((res) => {
      this.confirmLoading = false
      this.getForm(this.form.id)//刷新
      this.$notify({
        title: res,
        type: 'success'
      })
    })
        .catch(() => {
          this.confirmLoading = false
        })
  }
},
// 转采购退货单和采购退货出库单
transfer(id) {
  this.transferLoading = true
  toTransfer(id).then((res) => {
    this.transferLoading = false
    this.$notify({
      title: res,
      type: 'success'
    })
    this.refresh()
  })
      .catch(() => {
        this.transferLoading = false
      })
},
