1、store目录下添加Chat.js
const Chat = {
state: {
path: "222222",
token: "",
subject: ""
},
mutations: {
SET_TOKEN: (state,data) => {
state.token = data;
}
},
actions: {
/**
* this.$store.dispatch('setToken');
*/
setToken({ commit, state }, data) {
console.log(11111111111111)
commit('SET_TOKEN',data);
},
}
}
export default Chat
2、动态引入组件,并且在引入组件前先动态加载vuex模块
(1)组件写法
<el-dialog
:visible.sync="$store.state.chatMessageShowState"
:append-to-body="true"
:close-on-click-modal="false"
@close="showBtn(false)"
class="el-dialog-chat-unit"
>
<component :is="ChatMessage"></component>
</el-dialog>
(2)动态引入写法
// val 是否显示弹窗
showBtn(val){
if(!this.ChatMessage){
let options = {
lock: true,
text: '正在加载中...',
spinner: 'el-icon-loading',
background: 'rgba(0, 0, 0, 0.8)',
customClass: 'z-index-9999'
}
let loading = this.$loading(options)
// 动态注入模块
this.$store.registerModule("chat", require("./store/chat").default);
// 动态引入组件
this.ChatMessage = () => import('@/views/admin/chatMsg');
let timesIndex = 0;
timesIndex = setInterval(()=>{
if($(".ChatMessage").length) {
clearInterval(timesIndex)
loading.close();
}
},200)
}
this.$store.state.chatMessageShowState = val;
if(val) {
$("body").addClass("overflow-h");
}else {
$("body").removeClass("overflow-h");
}
}
3、页面中vuex的使用:
(1) 简单写法
console.log( this.$store.state.chat )
this.$store.dispatch('setToken');
(2)mapState的写法1
import { mapState } from "vuex";
computed: mapState({
path: (state) => state.chat.path,
}),
console.log(this.path)
(3)mapState的写法2
import { mapState } from "vuex";
computed: {
...mapState({
socket: (state) => state.chatSocket.socket,
}),
// 是否显示断网提示语
showTips() {
return !this.networkStatus || this.websocketState!=1; // 断网 || 离线状态
},
},
4、全局引入的vuex写法,其中单模块写法同1步骤
(1)store下添加index.js引入全局需要的vuex模块
import Vue from 'vue'
import Vuex from 'vuex'
import cached from './modules/cached'
import keycloak from './modules/keycloak'
import user from './modules/user'
import getters from './getters'
Vue.use(Vuex)
const store = new Vuex.Store({
modules: {
cached,
keycloak,
user
},
getters
})
export default store
(2)getter的写法
// 全局的用法 this.$store.getters.cachedViews
const getters = {
cachedViews: state => state.cached.cachedViews,
userInfor: state => state.user.userInfor,
networkStatus: state => state.user.networkStatus
}
export default getters
(3)main.js里引入
import store from './store'
window.vm = new Vue({
el: '#app',
router,
store,
render: h => h(App),
config: {
productionTip: false
},
created() {
// 加载完页面就初始化
store.dispatch('setInit');
}
})
5、vuex模块中常用写法
(1)举例store下的user.js和chat.js, 其中chat.js中使用user.js的userId
import user from '@/store/user';
actions: {
exitCurChat({dispatch, commit, state}) {
console.log( user.state.userInfo.id ); // user模块下的state
console.log( state.chatId ); // 当前模块下的state
commit('EXITCURCHAT'); // 当前模块下的mutations
dispatch('clearSendingInterval'); // 全部模块下的actions,所以注意不要同名
}
}
(2)Vue.set写法
import Vue from 'vue'
Vue.set(state.current, 'isFocus', false);
(3)router写法
import router from '@/router'
router.push("/consult/list");
(4)new Promise写法
(4.1)/api/group.js文件
import request from '@/utils/request' // axios拦截器
export function getGroupNoticeApi(groupId) {
return request({
url: GATEWAY_URL + '/group/notice/' + groupId,
method: 'get'
})
}
(4.2)vuex写法
import { getGroupNoticeApi } from '@/api/group'
actions: {
// 请求数据
getGroupNotice({ commit, state }, datas) {
let { groupId, isRead } = datas;
return new Promise((resolve, reject) => {
getGroupNoticeApi( groupId ).then(res => {
commit('SETGROUPNOTICEDATA',data);
resolve(res)
}).catch(error => {
reject(error)
})
})
}
}
dispatch("getGroupNotice",{
groupId: groupId,
isRead: false
});
