如何更改vue js模板中的日期格式

Vue.filter('dateFormat', function(value) {
  const date = new Date(value);
  const year = date.getFullYear();
  const month = date.getMonth() + 1;
  const day = date.getDate();
  return `${year}年${month}月${day}日`;
});

<p>{{ dateValue | dateFormat }}</p>

computed: {
  formattedDate() {
    const date = new Date(this.dateValue);
    const year = date.getFullYear();
    const month = date.getMonth() + 1;
    const day = date.getDate();
    return `${year}年${month}月${day}日`;
  }
}

<p>{{ formattedDate }}</p>
