如何将段落更改为内容更改的输入？

Question

我正在创建评论系统。我被封锁了。因为我想在点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.
          <br>
          <small> <a>Edit</a> · <a @click="openDeleteModal()">Usuń</a> · 3hrs</small>
        </p>
      </div>
    </div>
  </article>
  <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">
      <form @submit.prevent="addComment">
        <div class="field">
          <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"
              rounded
              native-type="submit"
            >
              Dodaj komentarz
            </b-button>
          </p>
        </div>
      </form>
    </div>
  </article>

我在评论区的trello中找到了想要的效果。有人可以帮助我吗？

Answer 1

您可以使每个元素有条件地打开 v-if 创建一个切换变量（或任何变量），点击它在您的内容和输入之间切换，为输入提供 paragragh 所需的初始值：

<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>
