# v-model Does Not Update During IME Composition
|
||||
|
||||
**Impact: MEDIUM** - When users type in languages that require an Input Method Editor (Chinese, Japanese, Korean, etc.), v-model won't update until the composition is complete. This breaks real-time validation, character counters, and live search features for international users.
|
||||
|
||||
IME (Input Method Editor) allows users to compose complex characters by typing multiple keystrokes. During this composition phase, v-model deliberately waits until the user confirms their selection before updating. This is usually desired, but can break features that need every keystroke.
|
||||
|
||||
## Task Checklist
|
||||
|
||||
- [ ] Test forms with IME input if your app serves CJK (Chinese, Japanese, Korean) users
|
||||
- [ ] For real-time features (live search, character counters), use manual event binding instead of v-model
|
||||
- [ ] Consider both behaviors when designing - sometimes waiting for composition completion IS correct
|
||||
- [ ] Document expected behavior for international users
|
||||
|
||||
**Problem - v-model waits for composition:**
|
||||
```html
|
||||
<script setup>
|
||||
import { ref } from 'vue'
|
||||
|
||||
const searchQuery = ref('')
|
||||
const charCount = ref(0)
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<!-- PROBLEM: During IME composition, searchQuery won't update -->
|
||||
<!-- Chinese user types "ni hao" -> sees no results until they press space/enter -->
|
||||
<input v-model="searchQuery" placeholder="Live search...">
|
||||
<p>{{ searchQuery.length }} characters</p>
|
||||
|
||||
<!-- Character counter stays at 0 during IME input -->
|
||||
</template>
|
||||
```
|
||||
|
||||
**Solution - Manual event binding for real-time updates:**
|
||||
```html
|
||||
<script setup>
|
||||
import { ref } from 'vue'
|
||||
|
||||
const searchQuery = ref('')
|
||||
|
||||
// This captures EVERY input event, including during IME composition
|
||||
function handleInput(event) {
|
||||
searchQuery.value = event.target.value
|
||||
}
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<!-- CORRECT: Manual binding captures all input, including IME composition -->
|
||||
<input
|
||||
:value="searchQuery"
|
||||
@input="handleInput"
|
||||
placeholder="Live search..."
|
||||
>
|
||||
<p>{{ searchQuery.length }} characters</p>
|
||||
</template>
|
||||
```
|
||||
|
||||
```html
|
||||
<!-- Shorter inline version -->
|
||||
<input
|
||||
:value="searchQuery"
|
||||
@input="event => searchQuery = event.target.value"
|
||||
>
|
||||
```
|
||||
|
||||
**When v-model behavior IS correct:**
|
||||
```html
|
||||
<!-- For form submission, waiting for composition IS usually better -->
|
||||
<!-- User expects to confirm their character selection before it's "official" -->
|
||||
<input v-model="formName" placeholder="Enter your name">
|
||||
|
||||
<!-- The final composed characters will be submitted, not intermediate states -->
|
||||
```
