Enhance precision with autofocus feature while utilizing Quasar's Q-Field validation

Currently, I am in the process of setting up a form using Quasar and implementing internal validation. The specific issue I am facing involves a group of checkboxes where the user must select at least one option. While I have successfully implemented the validation on form submit, there is one aspect that is causing me frustration: when the validation fails (meaning the user did not select any checkbox), there is no focus on that particular field, unlike with other fields utilizing internal validation. I suspect this might be due to my use of a q-field instead of a q-input.

Below is a snippet of my code for reference:

<q-field v-model="selectedFruits"
         class="q-gutter-sm"
         :rules="[ val => val.length >= 1 || 'Select at least one fruit']"
         :disable="isReadOnly()">
                <q-checkbox v-model="selectedFruits" val="Apple" label="Apple"/>
                <q-checkbox v-model="selectedFruits" val="Banana" label="Banana"/>
                <q-checkbox v-model="selectedFruits" val="Pear" label="Pear"/>
                <q-checkbox v-model="selectedFruits" val="Peach" label="Peach"/>
</q-field>

If anyone has any insights or suggestions to resolve this issue, please feel free to share.

Answer №1

Upon reviewing your code, I noticed that it is working as expected except for the disabled attribute which seems to be linked to a method, resulting in an error.

After conducting tests with [email protected], I observed that when the last checkbox remains unchecked, it retains focus even after displaying a validation error. Furthermore, clicking the space bar on the keyboard then marks the checkbox as checked.

const app = new Vue({
  el: '#root',
  data: {
    selectedFruits: []
  }
});

         >
                <q-checkbox v-model="selectedFruits" val="Apple" label="Apple"/>
                <q-checkbox v-model="selectedFruits" val="Banana" label="Banana"/>
                <q-checkbox v-model="selectedFruits" val="Pear" label="Pear"/>
                <q-checkbox v-model="selectedFruits" val="Peach" label="Peach"/>
</q-field>
    </div>
  </div>

  
<!--   :disable="isReadOnly()" -->
</div>

To utilize Vue3's composite API script setup, simply call ref on your field and then append .focus()

For instance:

 <template>
    <input type="text" ref="nameRef" v-model="name">
  <button @click="focus" value="Focus">
 </template>
<script setup>
   import {ref} from "vue"
   const name = ref("");
   const nameRef = ref(null);
     const focus = () => {
             nameRef.value.focus();
          }
</script>
