[vue] 怎么监听vuex数据的变化？

added

on Jun 20, 2019

说的是内部逻辑嘛?
computed, watch?
有点忘了, mark一下,

官网的图显示 Devtools好像是监视mutation的调用 mark一下

在mutations中监视

watch

//利用计算属性
  computed: {
        nowData() {
           return this.$store.state.nowData;
        }
  },

  //监听执行
  watch: {
      nowData(val) {
         // doSomeThing
      }
  },

补充非vue文件的监听方法官方文档：https://vuex.vuejs.org/zh/api/#watch；
