Having trouble accessing the ID value using Vue's $refs?

After reviewing the Vue $refs documentation, I am still unsure of how to retrieve the value of an id. When I check the console, I see that there is no object associated with it. Despite my efforts, using

console.log(this.$refs.dataInfo.id)
returns undefined.

Take a look at the following image: https://i.sstatic.net/dGudb.png

Javascript file:

console.log(this.$refs)

HTML file:

<tab-item v-for="item in category" :id="item.id" ref="dataInfo">{{item.name}}</tab-item>

Answer №1

console.log(this.$refs.dataInfo.id)
returns undefined because you are trying to access an element's attribute through a reference to a component. In this scenario, you can retrieve the id like so: this.$refs.dataInfo[0]['$el'].id

There is a different approach favored in Vue:

  1. Utilizing events. When props alter in the child component and you need to react in the parent component, emitting a custom event is beneficial. For instance, in the child component: this.$emit('dataChange', data). While in the parent component, add an event listener @dataChange="myMethod" to the component. https://i.sstatic.net/MQaP1.png
  2. Using Vuex.

Gaining knowledge of fundamental concepts such as how data flows within the application is crucial and shouldn't be underestimated!
