如何在javascript输入框中更改文本后立即调用函数

Question

in vue I am writing a form, input box when text changes it updates the function setMessage

<input type="text" v-model="test" v-on:change"setMessage">

but the problem is it only updates if I click somewhere outside the input box.

I believe their might be something other than change event !

您应该改用input事件：

<input type="text" v-model="test" v-on:input="setMessage">
