好吧,我正在尝试在Vue中更改"变量"的值,但是当我单击按钮时,它们会在控制台中抛出一条消息:

[Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "menuOpen"

我不知道如何解决这个问题......

我的file.vue:

<template>
  <button v-on:click="changeValue()">ALTERAR</button>
</template>

<script>

export default {
  name: 'layout',
  props: [ 'menuOpen' ],
  methods: {
    changeValue: function () {
      this.menuOpen = !this.menuOpen
    }
  },
}

</script>

任何人都可以帮助我吗？谢谢
