Is there a way to pass a reference to child components? For example:
The Parent component provides the ref:
<template>
<div ref="myRef" />
</template>
<script>
export default {
name: 'SearchContainer',
provide: {
parentRef: this.$refs.myRef
}
}
</script>
</style>
And the Child component injects it:
<template>
<div />
</template>
<script>
export default {
name: 'SearchCard',
inject: ['parentRef']
}
</script>
</style>
Typically, the communication between a parent and child component is best achieved through the use of props and emitted events:
<template>
<div />
</template>
<script>
export default {
methods:{
adjustParentLayout(){
this.$emit('adjust-layout')
}
}
}
</script>
</style>
parent :
<template>
<child @adjust-layout="modifyLayout" />
</template>
<script>
export default {
name: 'DisplayContainer',
methods:{
modifyLayout(){
//make changes to the style-related properties
}
}
}
</script>
</style>
Successfully implemented the process of providing refs to children. However, if there is a need for communication between parent and children components, Boussadjra Brahim's solution is highly recommended.
Despite that, using refs still has its own set of practical applications. Personally, I find it useful especially when dealing with dialogs.
Below is my approach:
<!-- Parent Component -->
<template>
<div ref="myRef"></div>
</template>
<script>
export default {
name: 'SearchContainer',
methods:{
getMyRef(){
return this.$refs.myRef
}
},
provide() {
return{
parentRef: this.getMyRef
}
}
}
</script>
<!-- Child Component -->
<template>
<div></div>
</template>
<script>
export default {
name: 'SearchContainer',
methods:{
useRef(){
this.parentRef().data // Can access data properties
this.parentRef().method() // can access methods
}
}
inject: ['parentRef']
}
</script>
