            price: 30.00,
            quant: 2
          }
        ]
      }
    },
    methods: {
      change (val) {
        console.log(val)
      }
    }
  }
</script>

<style scoped lang="less">
</style>

你好，
在@on-change="change"中，如果不带参数的话，methods中的change方法中的val是XNumber的currentvalue，
如果带参数的话怎么在change方法中获取XNumber的currentvalue

<x-number ref="fwref" v-for="app in minfos" :key="app.id" :title="app.pname" v-model="app.quant" button-style="round" :min="0"  @on-change="change(app.id)"></x-number>
