这是我的第一个问题,我真的很绝望,我希望你能帮助我。
我正在尝试使用 vuejs 构建像 Facebook 这样的帖子/评论/回复系统,在使用 Axios 获取数据库中的数据(使用 laravel API)后,我使用 v-for 循环所有帖子/评论/回复,这里的问题是,我在 v-for 循环内的表单上附加了 v-model 的输入,当我输入我的输入时,它出现在已循环的所有其他输入中,这是一个用于更好理解的图像 ->重复输入,
<div class="panel panel-white post panel-shadow" v-for="(post) in posts" >
<div class="post-heading">
<div class="pull-left image">
<img src="https://bootdey.com/img/Content/user_1.jpg" class="img-circle avatar" alt="user profile image">
</div>
<div class="pull-left meta">
<div class="title h5">
<a href="#"><b>{{post.user.name}} </b></a>
made a post.

<h6 class="text-muted time">(number) minute ago</h6>

最简单的方法是将每个帖子、评论和回复放在单独的组件中,记住这是组件,具有单独的状态(或数据),您可以轻松地操作它,这样您不仅写得很难扩展,而且还难以阅读。
但唯一的方法是在循环中绑定状态,就像我说的那样,你可以尝试使用计算
v-model="replies[index].reply"
to:
v-model="replyComputed(index)"
