vue 组件状态监听 && 数据推送监听

首先，组件中引入vuex

import vuex from "vuex";

其次，计算 state 的值变化

computed: {
    state() {
      return this.$store.state["MODULE_DEVICE_MONITOR"];
    },
 },

最后，监听 state

• 组件状态监听

'state.selectedItem' (newVal) {
    console.log(newVal)
}

• 消息推送监听

'state.deviceDataWS': {
  handler (newName, oldName) {
      console.log(newName, oldName)
  },
  deep: true,
  immediate: true,
}
