多個組件通訊問題EventBus傳值,頻繁會致使接口重複調用javascript
我覺得eventBus是專門處理兄弟組件之間通訊的,可是實際上,eventBus是專門處理同一個路由下的複雜組件之間通訊的。
若是涉及誇路由的組件通訊。能夠考慮利用$route對象傳參或者Vuexvue
因爲涉及v-model,須要特殊處理:java
buggit
computed property "XXX" was assigned to but it has no setter
componentgithub
computed: { ...mapGetters({ nameFromStore: 'name' }), name: { get(){ return this.nameFromStore }, set(newName){ return newName } } }
storevuex
export const store = new Vuex.Store({ state:{ name : "Stackoverflow" }, getters: { name: (state) => { return state.name; } } }
component 頁面this
<template> <div v-model="common.checkStatus"> 123 </div> </template> <script> import {mapState} from "vuex" export default { //component 頁面 computed部分 //computed computed: { ...mapState({ common:state => state.common, checkStatus:state => state.common.checkStatus }), } //component 頁面 watch部分 //watch 實時監聽checkStatus watch: { checkStatus(newVal){ if(newVal){ }else{ } } } } </script>
store下的common.jscode
const state = { checkStatus:false } const getters = {} const actions = {} const mutations = { setCheckStatus(state,payload){ state.checkStatus = payload } } export default { state, getters, actions, mutations }
其餘 component頁面 實時監聽checkStatuscomponent
import {mapState} from "vuex" export default { computed: { ...mapState({ checkStatus:state => state.common.checkStatus }), }, //watch 實時監聽checkStatus watch: { checkStatus(newVal){ if(newVal){ }else{ } } } }
其餘 component頁面 更新checkStatus對象
import {mapState} from "vuex" export default { methods:{ clickOpen(){ this.$store.commit("setCheckStatus",true) }, clickClose(){ this.$store.commit("setCheckStatus",false) } } }
