Using Vue 3's emit in place of v-model

I am facing a challenge with integrating a custom dropdown select component. The idea is to use v-model to retrieve data from the parent component, but I am unsure how to pass that through an emit. Can anyone clarify this for me?

Here is my parent component where I am calling the selector:

<DropdownSelect :items="items"/>

As you can see, I am passing an array of objects and the child component is iterating through them. How can I use v-model to get the selected data in the child component?

In the child component, I have an onClick function which contains the selected object:

emit('selected', get);

Is there an easy way to achieve something like this:

<DropdownSelect :items="items" v-model="something" />

without using emit? Perhaps I could do:

<DropdownSelect :items="items" @selected="object_here"/>

But I specifically need it to work with v-model. Is that possible?

Answer №1

found at https://www.example.com/tutorial/vuejs-v-model-implementation:

In order to grasp how v-model support can be added to your components, it is crucial to have a deep understanding of its internal workings. The v-model="property" syntax essentially translates to :value="property" @input="property = arguments[0]".

v-model is triggered by the 'input' event emission,

Experiment with: this.$emit('input', newData); within your component.
