Form Input Binding

Text, textarea, select, checkbox, and radio each use v-model with slightly different semantics. This lesson covers practical patterns, syntax, and mistakes to avoid.

Binding Inputs with v-model

Text, textarea, select, checkbox, and radio each use v-model with slightly different semantics.

Checkbox groups bind to arrays of chosen values.

<input v-model="text" />
<textarea v-model="bio" />
<select v-model="city"><option>NYC</option></select>

Common control bindings.

Value Types

strings, numbers (.number), booleans, arrays

Prefer Composition API + script setup.
Use computed for derived UI.
Keep side effects intentional.
Practice in a small Vite app.
