I'm new in Quasar Framework
and Vue.js
. I wanted to use q-option-group
for my simple application. However, model-value and @update:model-value didn't switch option from one to another. I know, I can use v-model
but I can also use model-value instead of it by the quasar documentation.
I just wonder how it is used.
HTML
<div id="q-app" style="min-height: 100vh;">
<div class="q-pa-lg">
<q-option-group
:model-value="selected_fruit"
:options="fruits"
color="dark"
@update:model-value="value => { selected_fruit = value }"
></q-option-group>
</div>
</div>
VUE
const { ref } = Vue
const app = Vue.createApp({
setup () {
return {
selected_fruit: 'apple',
fruits: [
{
label: 'Apple',
value: 'apple'
},
{
label: 'Banana',
value: 'banana'
},
{
label: 'Pear',
value: 'pear'
}
]
}
}
})
app.use(Quasar, { config: {} })
app.mount('#q-app')
Thank you for answers
You need to make it reactive with ref
or reactive
:
const { ref } = Vue const app = Vue.createApp({ setup () { const fruits = ref([{label: 'Apple', value: 'apple'}, {label: 'Banana', value: 'banana'}, {label: 'Pear', value: 'pear'}]) const selected_fruit = ref('apple') return { selected_fruit, fruits} } }) app.use(Quasar, { config: {} }) app.mount('#q-app')
