Exploring the capabilities of Vue JS to dynamically update data and model bindings within form

I need help creating a form that allows users to edit their comments. The challenge is to display the current value of the comment using dynamic data from v-for, while also binding the value to a model for sending it with a patch request.

Here is an example of how the form currently appears:

<p @click="editing = true">
     Edit comment
</p>
<form v-if="editing" @submit.prevent="editComment(comment._id)">
   <input type="text" v-model="comment.message"/>
   <button type="submit">
     Edit Comment
   </button>
 </form>

Is there a way to merge the v-model and :value binding? Or perhaps a method to bind the model value and specify the data name?

Answer №1

To ensure each comment is displayed within its own component, you can follow this approach (not tested):

Parent component:

<template>
  <div>
    <Comment 
      v-for="comment in comments"
      :key="comment._id"
      :comment="comment"
      @on-update="onUpdateComment"
    />
  </div>
</template>

<script>
  export default {
    data () {
      return {
        comments: [] // This array could also be a computed property or populated elsewhere in the component
      }
    },

    methods: {
      onUpdateComment({ commentId, value }) {
        // Implement update logic here
      }
    }
  }
</script>

Child component (Comment):

<template>
  <div>
    {{ comment.message }}

    <p @click="onClickEdit">
        Edit comment
    </p>

    <form v-if="editing" @submit.prevent="editComment">
      <input type="text" :value="updatedCommentMessage"/>

      <button type="submit">
        Edit Comment
      </button>
    </form>
  </div>
</template>

<script>
  export default {
    props: {
      comment: {
        type: Object
      }
    },

    data () {
      return {
        editing: false,
        updatedCommentMessage: ''
      }
    }

    methods: {
      onClickEdit () {
        this.editing = true
        this.updatedCommentMessage = this.comment.message
      },

      editComment () {
        this.$emit('on-update', { commentId: this.comment.id, value: this.updatedCommentMessage})
      }
    }
  }
</script>

By storing the message to be edited in a separate variable, it allows for easy cancellation by resetting the updatedCommentMessage variable.
