1.vuex的store里面设置属性和方法

 { 
    moduleName: "Cur", //存储单元名字
    content: {
      namespaced: true,
      state: {
        content: 0  //存储属性值，可以设置多个
      },
      mutations: {
        setCur: (state, content) => {   // 设置存值方法
          state.content = content
        }
      }
 }

2.Vuex存值

this.$store.commit('Cur/setCur', 5);

3.Vuex取值

this.$store.state.Cur.content;
