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‘
})
}
