Last Updated :
08 Jul, 2020
The v-on:keyup directive is a Vue.js directive used to add an event listener to an button in the keyboard. First, we will create a div element with id as app and let’s apply the v-on:keyup directive to the input element. Further, we can execute a function when we press the associated key.
Syntax:
v-on:keyup="function"
Supported Keys: Following keys are supported:
- Enter key: .enter
- Tab key: .tab
- Delete key: .delete
- Esc key: .esc
- Up key: .up
- Down key: .down
- Left key: .left
- Right key: .right
Parameters: This directive holds function as a value that will be executed when the key event occurs.
Example: This example uses VueJS to toggle the visibility of a element with v-on:keyup using Enter key.
