vue 2 trigger computed with chinese input issue

Question

I'm using vue2 to delveop my project.

I found that the computed property will only trigger when we keyup/keydown chinese input to a word.

(ex: ㄨㄛˇ => 我 It will only trigger 1 times not 3 times when it format to a word)

It's not like pure javascript's event. Is that correct !?

Can you add relevant code snippets. – Saurabh Dec 02 '16 at 04:12 — Saurabh, Dec 02 '16 at 04:12

You are correct! From the docs (https://v2.vuejs.org/v2/guide/forms.html):

For languages that require an IME (Chinese, Japanese, Korean etc.), you’ll notice that v-model doesn’t get updated during IME composition. If you want to cater for these updates as well, use input event instead.

Try this:

new Vue({
  el: '#app',
  data: {value: ''}
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.1.4/vue.js"></script>

<div id="app">
  <p>The value is: {{value}}</p>
  <input v-on:input="value = $event.target.value"/>
</div>
