# vue/valid-v-on

enforce valid v-on directives

  • ⚙️ This rule is included in all of "plugin:vue/essential", "plugin:vue/strongly-recommended" and "plugin:vue/recommended".

This rule checks whether every v-on directive is valid.

# 📖 Rule Details

This rule reports v-on directives in the following cases:

  • The directive does not have that event name. E.g. <div v-on="foo"></div>
  • The directive has invalid modifiers. E.g. <div v-on:click.bbb="foo"></div>
  • The directive does not have that attribute value and any verb modifiers. E.g. <div v-on:click></div>
<template> <!-- ✓ GOOD --> <div v-on="foo"/> <div v-on:click="foo"/> <div @click="foo"/> <div @click.left="foo"/> <div @click.prevent/> <div @click.stop/> <!-- ✗ BAD --> <div v-on/> <div v-on:click/> <div v-on:click.aaa="foo"/> <div @click/> </template>

Note

This rule does not check syntax errors in directives because it's checked by no-parsing-error rule.
