disallow confusing v-for and v-if on the same element

📖 Rule Details

This rule reports the elements which have both v-for and v-if directives in the following cases:

  • The v-if directive does not use the reference which is to the variables which are defined by the v-for directives.

In that case, the v-if should be written on the wrapper element.

<template> <!-- ✓ GOOD --> <TodoItem v-for="todo in todos" v-if="todo.shown" :todo="todo" /> <ul v-if="shown"> <TodoItem v-for="todo in todos" :todo="todo" /> </ul> <!-- ✗ BAD --> <TodoItem v-if="complete" v-for="todo in todos" :todo="todo" /> </template>
Now loading...


When they exist on the same node, v-for has a higher priority than v-if. That means the v-if will be run on each iteration of the loop separately.
