Guide to utilizing $refs effectively in Vue.js templates

Is there a way to display the input value automatically without using v-model and by making use of the "ref" attribute?

<div class="form-group m-b-40">
  <input type="text" class="form-control" id="name" ref="name" required> 
</div>
{{showInput}}

I attempted to achieve this functionality by writing the following method:

 methods: {
       showInput: function () {
            this.$refs.name.value
        },
    }

However, the value isn't being updated as expected. Any suggestions on how to resolve this issue?

Answer №1

The true value of a reference is not considered observable unless it is linked to the component instance:

data() {
    return {
        personName: ''
    }
}

Simply assign your input element a :value="personName" and now it will have an observer associated with it

I'm having trouble grasping your objective, but it seems like the approach you're taking is incorrect. Regardless, you mentioned that you do not want to utilize v-model.

Allow me to demonstrate how this can be achieved without using v-model - by fetching the input value from an API (you will need to implement your own code for this) and setting it to the input:

 <template>
    <div>
      <div class="form-group m-b-40">
        <input type="text" :value="text" @input="updateValue"> 
        <hr>
      </div>
      The input value is: {{text}}
    </div>
 </template>

<script>
export default {
  data() {
    return {
        text: ''
    }
  },
  created() {
    this.fetchFromApi()
  },
  methods: {
    updateValue(value) {
        let newValue = value.target.value
        this.text = newValue
    },
    fetchFromApi() {
        //write the code to get from API the input value and then:
      this.text = 'input value' //set the input value
    }
  }
}
</script>
