qInput component with 2-ways-bind

Salim Larhrib

Hi all,
I have discovered Quasar 2 days ago and have started to play with. I need to do 2-ways-bind between a vue3 page and an included q-input descendant.
It took time but it works. I need an advice if there is a better solution or my way to do is the right one.
To be short, I have created a local v-model in the component and made a main model update with an emit event.

<template>
  <div>
    <q-input
      class="col-md-2"
      v-model="innerValue"
      :label="pLabel"
      :placeholder="pPlaceholder"
      dense
      @input="updateValue($event)"
    />
  </div>
</template>

<script>
export default {
  name: 'BaseInput',
  props: {
    modelValue: {
      type: [String, Number],
      default: '',
      required: true
    },
    pLabel: {
      type: String,
      required: true
    },
    pPlaceholder: {
      type: String,
      default: ''
    },
    pType: {
      type: String,
      default: 'text'
    },
    pIcon: {
      type: String,
      default: ''
    }
  },
  data () {
    return {
      innerValue: this.modelValue
    }
  },
  methods: {
    updateValue () {
      this.$emit('input', this.innerValue)
    },
    handleChange () { console.log('Change event') }
  },
  model: {
    // Quasar components waits "value" property when Vue3 sends "modelValue"
    // though v-model call.
    // We translate "value" property to "modelValue"
    type: String,
    prop: 'modelValue'
  }
}

To use the BaseInput component, I include it in my template like this:

<!-- Field Start Date -->
<BaseInput
  v-model="dName"
  label="User Name "
  placeholder="Insert unique user name"
/>
....
  data () {
    return {
      dName: 'Tartempion',
.....

I am Waiting for your comments and nice advices to improve this 2-ways binding solution.
Thanks to all.

Here’s an article about events and props in the context of child and parent components in Vue.

You could also extend Qinput in BaseInput.

Hi Dobbel,
Thank you for your links. I will take a look to mixins to extend existing Quasar components.
I have also found a very interesting post which purposes a better solution with computed functions to manage the local v-model innerValue : https://forum.quasar-framework.org/topic/3208/adding-custom-functionality-to-quasar-s-components

Hello,
Again another example to simplify 2 ways bindings thanks to computed getter and setter. https://tahazsh.com/vuebyte-computed-setters
