Vue.js Parent Call Child Component Method 单个定义的 ref ,使用 this.$refs.xxx 获取的是 一个组件的实例对象 通过v-for 循环后多个定义的 ref,使用 this.$refs.xxx 获取的是 一个组件的实例对象的数组 methods: { clickRef(index) { const ref = `ref_${index}`; co...
第一种方法是直接在子组件中通过this.$parent.event来调用父组件的方法 父组件 <template> <child></child> </template> import child from '~/components/dam/child'; export default { components: { child }, methods: { fatherMethod() { console.log('测试'); } } }; 子组件 <template> ...
复制 <template><children ref="children"></children></template>importchildrenfrom'components/children.vue'exportdefault{components:{children},data(){return{}},methods:{parentMethod(){//返回一个对象this.$refs.children// 调用children的changeMsg方法this.$refs.children.changeMsg()}}} 这种方式我们可以...
import HeaderPart from "./HeaderPart"; export default { components: { HeaderPart }, data() { return { title: "父组件" }; }, methods: { callChildMethod() { console.log("父组件中调用子组件printName方法"); this.$refs.headerChild.printName(); ...
callChildMethod() { // 通过 this.$refs 访问子组件实例,并调用子组件方法 this.$refs.childRef.childMethod(); } } } 通过这种方式,在父组件中使用this.$refs.childRef即可访问子组件实例,并调用其中定义的方法。 二、使用事件机制 在子组件中
Child } };<!-- Child.vue --><template>Notify Parent</template>exportdefault{ methods: { notifyParent(){ this.$emit('notifyParent','Hello from Child!');} } }; 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14.
this.$parent.parentMethod(); } } } ``` 2. **使用事件(更推荐的方式)**: Vue推荐使用事件来在父子组件之间进行通信。你可以在父组件中定义一个事件,然后在子组件中触发这个事件。父组件可以监听这个事件并执行相应的逻辑。 父组件: ```vue <template> <child-component @childEvent="parentMethod"><...
There are other ways to access child functions e.g. using events and props. But in this example, we’ll access child functions usingrefs. Let’s start by creating our parent component. We’ll call itHeader.vue. It will be a layout component, which will have a site navigation bar, logo...
With the built-in$emit()method in Vue we can create a custom event in the child component that can be captured in the parent element. Props are used to send data from the parent element to the child component, and$emit()is used to do the opposite: to pass information from the child...
