Vue 实现手动刷新组件的方法

// store/view.js
const state = {
 viewId: 1
};
const getters = {
 getViewId: state => {
  return state.viewId;
 }
};
const mutations = {
 setViewId: (state, payload) => {
  state.viewId++;
 }
};
const actions = {
 setViewId: (context, payload) => {
  context.mit("setViewId", payload);
 }
};
export default {
 namespaced: true,
 state,
 getters,
 mutations,
 actions
};

methods: {
  fresh() {
    this.$store.dispatch("view/setViewId")
  }
}
