vuex reset state

一般写法

const state = {
  a: 1,
  b: { c: 1}
};

export default { state };

如果有重置状态的需求

const defaultState = () => ({
  a: 1,
  b: { c: 1}
});

const state = defaultState();

const actions = {
  reset({commit}) {
    commit('reset');
  }
};

const mutations = {
  reset(state) {
    const initState = defaultState();
    Object.keys(state).forEach( x => {
      state[x] = initState[x];
    });
  }
};

export default { state, actions, mutations };
