1.父子之间通讯
父组件传值给子组件,通过props属性的传递,子组件通过$emit事件的触发。
2.自定义事件,非父子组件传值,比如此处是兄弟组件传值
input组件里,触发:
event.js: event是一个vue实例。
list组件里调用:mounted钩子函数里调用,beforeDestory里销毁。
3.中央总线bus传值
在utils里新建一个eventBus.js文件
const install = (Vue) => { const Bus = new Vue({ methods: { emit(event, ...args) { this.$emit(event, ...args); }, on(event, callback) { this.$on(event, callback); }, off(event, callback) { this.$off(event, callback); }, }, }); Vue.prototype.$bus = Bus; }; export default install;
在main.js中引用
import VueBus from './utils/eventBus';
Vue.use(VueBus);
在组件xingyezilvtqcjiancha.vue中触发
sendMsg() { let sendMsgInfo = JSON.parse(window.localStorage.getItem('sendMsgInfo')); $http.post('/sdkseaunion/portalApi/sendSmsMes', { sendPhone: sendMsgInfo.lianxidianhua, sendName: sendMsgInfo.displayValue, owner: sendMsgInfo.owner, shipName: localStorage.getItem('shipName'), }) .then((rspData) => { this.$message({ type: 'success', message: '短信发送成功!' }); this.$bus.emit('refreshData'); destroyAllDialogs(); }).catch((error) => { console.log(error); }); },
在shipInfo.vue中引用
created() { this.$bus.on('refreshData', () => { this.queryTabList(); this.queryTabContent(); }); setInterval(this.showMarquee, 3000); }, beforeDestroy () { this.$bus.off('refreshData'); },
