There was a problem using v-model to the div tag. Apparently, the div tag does not allow v-model and I decided to create my comments section as a component. For UI/UX reasons I need to allocate this div textarea as is. textarea, input and other tags, as far as I know, these tags are not compatible with contenteditable="true";; I need to expand when the user enters a comment The height of the input field. Below is the vue component I imported in the parent view.
<!-- CommentSection.vue -->
<template>
<div id="chatId" contenteditable="true" placeholder="Leave a message" class="overflow-hidden block mx-4 text-left p-2.5 w-full text-sm text-gray-900 bg-white rounded-2xl border border-gray-300 focus:ring-blue-500 focus:border-blue-500"/>
</template>
<style>
#chatId[contenteditable="true"]:empty:not(:focus):before {
content: attr(placeholder)
}
</style>
In my view file, I import it and use v-model into it, like this.
<!--MainPage.vue-->
<template>
...
...
<CommentSection v-model="comment"/>
<button @click="submitPost()"> Submit </button>
...
...
...
</template>
<script>
import CommentSection from '@/components/CommentSection.vue'
export default{
name: 'MainPage',
data(){
return{
comment: '',
}
},
components: { CommentSection },
methods:{
submitPost(){
console.log(this.comment);
},
},
}
</script>
But when I check the console it gives me the value "null" or nothing. Is there a way to solve this problem? Or maybe the way I implemented it is causing the problem.
EDIT: Here is the code running in codesandbox.

I solved your problem, the code is as follows. Hope this helps you
By adding @ in the div tag, we can see the change in the tag content in the change method. In this method, use emit$ to share its value with other components
<!-- CommentSection.vue --> <template> <div id="chatId" @input="chanage" contenteditable="true" placeholder="Leave a message" class="overflow-hidden block mx-4 text-left p-2.5 w-full text-sm text-gray-900 bg-white rounded-2xl border border-gray-300 focus:ring-blue-500 focus:border-blue-500"/> </template> <script> export default { methods: { chanage (e) { this.$emit('value-div', e.target.textContent) } } } </script> <style> #chatId[contenteditable="true"]:empty:not(:focus):before { content: attr(placeholder) } </style>Here we have the props created by $emit, and we initialize its value in the comment variable. In fact, it has functions similar to v-model.
<!--MainPage.vue--> <template> ... ... <CommentSection @value-div="(value)=>comment = value"/> <button @click="submitPost()"> Submit </button> ... ... ... </template> <script> import CommentSection from '@/components/CommentSection.vue' export default{ name: 'MainPage', data(){ return{ comment: '', } }, components: { CommentSection }, methods:{ submitPost(){ console.log(this.comment); }, }, } </script>
