父组件: <template> <div> <div @click="openChild">弹弹弹,弹出子组件</div> <childs ref="alert" @watchChild="parentReceive"></childs> <!--监听子组件绑定的方法--> </div> </template> <script> import childs from '../components/modal/Alert' export default{ data(){ return { msg: '我是父组件的msg!!!' } }, components:{ childs }, methods:{ parentReceive(message){ alert(message); }, openChild(){ this.$refs.alert.open('我是子组件','子组件内容!!!!!'); } } } </script> <style> </style> 子组件: <template> <modal :show='show' ref="modal"> <div slot="title">{{title}}</div> <div slot="content">{{content}}</div> <div slot="buttons" class="modal-buttons"> <span class="modal-button" @click="_onClick()">确定</span> </div> </modal> </template> <script> import Modal from './Modal' export default { props: { show: { type: Boolean, default: false }, okText: { type: String, default: '确定' }, }, data(){ return { title: '', content: '' } }, components: { Modal }, methods: { open (title, content) { this.title = title this.content = content this.$refs.modal.open() }, close () { this.title = '' this.content = '' this.$refs.modal.close() }, _onClick(){ this.close(); this.$emit('watchChild','我是从子组件传过来的内容!!!'); //触发$emit绑定的watchChild方法 } } } </script> 第一种方法: 如上:通过this.$emit()来触发父组件的方法。具体就是子组件触发$emit绑定的事件watchChild,然后父组件监听watchChild,一旦watchChild被触发便会触发父组件的parentReceive方法。 父组件: <template> <div> <div @click="openChild">弹弹弹,弹出子组件</div> <childs ref="alert" :on-ok="parentReceive"></childs> <!--把父组件的方法名传给子组件的onOK属性--> </div> </template> <script> import childs from '../components/modal/Alert' export default{ data(){ return { msg: '我是父组件的msg!!!' } }, components:{ childs }, methods:{ parentReceive(message){ alert(message); }, openChild(){ this.$refs.alert.open('我是子组件','子组件内容!!!!!'); } } } </script> <style> </style> 子组件: <template> <modal :show='show' ref="modal"> <div slot="title">{{title}}</div> <div slot="content">{{content}}</div> <div slot="buttons" class="modal-buttons"> <span class="modal-button" @click="_onClick()">确定</span> </div> </modal> </template> <script> import Modal from './Modal' export default { props: { show: { type: Boolean, default: false }, okText: { type: String, default: '确定' }, onOk: { //定义onOK属性 type: Function } }, data(){ return { title: '', content: '' } }, components: { Modal }, methods: { open (title, content) { this.title = title this.content = content this.$refs.modal.open() }, close () { this.title = '' this.content = '' this.$refs.modal.close() }, _onClick(){ this.close(); if(this.onOk){ this.onOk('我是子组件传递过来的数据!!!!'); } } } } </script> 第二种方法: 在子组件props中定义属性onOK,类型为function,然后在父组件中把要触发的方法名传递给onOK属性,最后在子组件中判断onOk是否存在,是的话直接执行这个方法。 效果: --------------------- 作者:yemuxia_sinian 来源:CSDN 原文:https://blog.csdn.net/yemuxia_sinian/article/details/80534296 版权声明:本文为博主原创文章,转载请附上博文链接!
