v-model nggawé dual-arah binding antaraning input form lan sapisan saka state: input nunjukke nilai saka state, lan ngedit input ngupdate state — automatik, ing loro arah.
<script setup>
import { ref } from "vue";
const name = ref("");
</script>
<template>
<input v-model="name" />
<p>You typed: {{ name }}</p> <!-- updates live as you type -->
</template>
Ingas tutug, nggabung bind lan listener:
v-model:value@input<!-- these two are equivalent -->
<input v-model="name" />
<input :value="name" @input="name = $event.target.value" />
Dadi ora magic — mung singkatan sampun kanggo bind-lan-update pattern.
<template>
<input v-model="text" /> <!-- text -->
<textarea v-model="message" />
<input type="checkbox" v-model="agreed" /> <!-- boolean -->
<input type="radio" value="a" v-model="choice" />
<select v-model="selected">...</select>
</template>
Vue milih property/event sing pas kanggo saben tipe control (value/input, checked/change, lsp.).
<input v-model.trim="name" /> <!-- auto-trim whitespace -->
<input v-model.number="age" /> <!-- cast to a number -->
<input v-model.lazy="text" /> <!-- sync on `change` instead of every keystroke -->
<!-- a component can support v-model via a `modelValue` prop + `update:modelValue` event -->
<CustomInput v-model="name" />
<!-- equivalent to :model-value="name" @update:model-value="name = $event" -->
Iki ngidini sampeyan mbangun reusable input component sing nggunakake v-model kaya input native (Vue 3 malah ndhukung pirang-pirang named v-model: v-model:title, v-model:body).
v-model iku inti saka form ing Vue — ngilangi manual value-binding + event-handling boilerplate kanggo dual-arah data flow.
Paham yen v-model desugar dadi :value + @input ngilangi misteri lan njelaske carane nggawé v-model ing sariro komponen, nalika modifier (.trim/.number/.lazy) nangani umum input-processing perlu declaratively.
