Question

我正在创建评论系统。我被封锁了因为我想在单击编辑后将段落更改为输入。这是我的代码：

    <section class="modal-card-body">
  <p v-html="modalData.description" />
</section>
<section class="modal-card-body">
  <article class="media">
    <figure class="media-left">
      <p class="image is-64x64">
        <img src="https://bulma.io/images/placeholders/128x128.png">
      </p>
    </figure>
    <div class="media-content">
      <div class="content">
        <strong>Barbara Middleton</strong>
        <p>
          Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis porta eros lacus, nec ultricies elit blandit non. Suspendisse pellentesque mauris sit amet dolor blandit rutrum. Nunc in tempus turpis.

    </figure>
    <div class="media-content">
      <form @submit.prevent="addComment">

          <p class="control">
            <textarea v-model="contentComment" class="textarea" placeholder="Add a comment..." required />
          </p>
        </div>
        <div class="field">
          <p class="control">
            <b-button
              type="is-success"

看起来像这样：

我在注释部分的trello中找到了想要的效果。有人可以帮我吗？

Answer 1

您可以使用v-if有条件地打开每个元素，以创建一个切换变量（或其他变量），该单击变量可以在单击时在内容和输入之间切换，为输入提供期望的初始值：

<input v-model="paragraghText"/>
...
paragraphText = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis porta eros lacus, nec ultricies elit blandit non. Suspendisse pellentesque mauris sit amet dolor blandit rutrum. Nunc in tempus turpis."

这是我的工作示例：

Vue.component("comment", {
  template: "#comment",
  data() {
    return {
      edit: false,
      content: this.value
    };
  },
  props: {
    author: String,
    value: String
  },
  methods: {
    doEdit() {
      this.edit = true;
    },
    doSave() {
      this.edit = false;
      this.$emit("input", this.content);
    }
  }
});

Vue.component("comments", {
  template: "#comments",
  data() {
    return {
      comments: [
        {
          id: 1,
          author: "Fus",
          message: "Lorem ipsum dolor sit amet, consectetur adipiscing elit."
        },
        {
          id: 2,
          author: "Ro",
          message: "Etiam nec sapien non arcu faucibus gravida at nec felis."
        },
        {
          id: 3,
          author: "Dah",
          message:
            "In ac felis libero. Morbi placerat sit amet nisi eu ultrices."
        }
      ]
    };
  }
});

new Vue().$mount("#app");

.content,
.author {
  margin: 5px;
  max-width: 300px;
  border: 1px dashed gray;
  background-color: silver;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
  <comments></comments>
</div>

<script type="text/x-template" id="comments">
  <section>
    <comment v-for="item in comments" v-model="item.message" :author="item.author" :key="item.id"></comment>
  </section>
</script>

<script type="text/x-template" id="comment">
    <article>
        <div class="author">Who: {{ author }}</div>
        <div v-if="edit"><textarea v-model="content"></textarea></div>
        <div v-else class="content">{{ value }}</div>
        <button v-if="edit" @click="doSave">Save</button>
        <button v-else @click="doEdit">Edit</button>
    </article>
</script>
