1:uni-app 集成了vuex 直接在根目录下创建store文件夹 新建store.js
import Vue from ‘vue‘
import Vuex from ‘vuex‘
import ‘模块名称’ from ‘模块路径‘;
Vue.use(Vuex);
const $store = new Vuex.Store(
modules:
‘引入的模块名称’,
);
export default $store;
2:在main.js中引入挂载store
import store from ‘./store/store.js‘
Vue.prototype.$store = store
3:在store文件夹下新建文件 ‘模块名称’
新建:
actions.js
getters.js
index.js
mutations.js
state.js
types.js
4:在index.js中引入
import state from ‘./states‘;
import getters from ‘./getters‘;
import mutations from ‘./mutations‘;
import actions from ‘./actions‘;
export default
namespaced: true, //namespaced写成true,意思就是可以用这个module名作为区分了
state,
mutations,
actions,
getters
;
5:actions.js
import * as TYPES from ‘./types‘ //actions分发事件类型
const actions =
changeNum(context)
context.commit(TYPES.CHANGE_NUM)
;
export default actions
6:getters.js
const getters =
;
export default getters
7:mutations.js
import * as TYPES from ‘./types‘
const mutations =
[TYPES.CHANGE_NUM](state)
state.number = state.number+1
,
;
export default mutations
8:types
export const CHANGE_NUM = ‘CHANGE_NUM‘;
9:在组件中使用
computed:
...mapState(
number:(模块名称)=>模块名称.number,
)
,
methods:
...mapActions(
add:‘模块名称/模块下的方法‘
)
