JS.VUE.VALID.V.MODEL

Enforce valid 'v-model' directives

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

Rule Details

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

  • The directive used on HTMLElement has an argument. E.g. <input v-model:aaa="foo">
  • The directive used on HTMLElement has modifiers which are not supported. E.g. <input v-model.bbb="foo">
  • The directive does not have that attribute value. E.g. <input v-model>
  • The directive does not have the attribute value which is valid as LHS. E.g. <input v-model="foo() + bar()">, <input v-model="a?.b">
  • The directive has potential null object property access. E.g. <input v-model="(a?.b).c">
  • The directive is on unsupported elements. E.g. <div v-model="foo"></div>
  • The directive is on <input> elements which their types are file. E.g. <input type="file" v-model="foo">
  • The directive's reference is iteration variables. E.g. <div v-for="x in list"><input type="file" v-model="x"></div>

{'vue/valid-v-model': ['error']}

Copy
<template>
  <!-- GOOD -->
  <input v-model="foo">
  <input v-model.lazy="foo">
  <textarea v-model="foo"/>
  <MyComponent v-model="foo"/>
  <MyComponent v-model:propName="foo"/>
  <MyComponent v-model.modifier="foo"/>
  <MyComponent v-model:propName.modifier="foo"/>
  <div v-for="todo in todos">
    <input v-model="todo.name">
  </div>

  <!-- BAD -->
  <input v-model>
  <input v-model:aaa="foo">
  <input v-model.bbb="foo">
  <input v-model="foo + bar">
  <input v-model="a?.b.c">
  <input v-model="(a?.b).c">
  <div v-model="foo"/>
  <div v-for="todo in todos">
    <input v-model="todo">
  </div>
</template>

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