用的element-dialog，将弹框组件化，所以用vuex来改变弹框的显隐藏。

密码为用户登录时的密码，将其存储在本地，判断表单里的原密码是否与其相同，采用了element自带的表单验证规则

 

在store.js里设置dialog的初始值

import Vue from 'vue'
import Vuex from 'vuex'

Vue.use(Vuex)

export default new Vuex.Store({
  state: {
    changePwd:false,
  },
  mutations: {
    changepwd(state,flag){
      state.changePwd = flag
    }
  },
  actions: {
    changeUserpwd({commit},flag){
      commit('changepwd',flag)
    }
  }
})
