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')<link href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons" rel="stylesheet" type="text/css">
