There's an issue when using v-model to div tags. Apparently, div tags doesn't allow v-model and I've decided to create my comment section as a component. I needed to assign this div text area as is because of UI/UX reasons. textarea, input, etc tags, as to my knowledge, these tags are not compatible with contenteditable="true"; I need to expand the height of the input field as a user types in their comments. Below is the vue component that I imported in my 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>
On my view file, I imported it and used v-model into it, just 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>
However, when I check my console, it gives me the value "null" or just nothing. Is there's a way to fix this? Or is it the way I implemented it that causes the problem. Thank you in advance for anyone who can help!
EDIT: Here's the running code in codesandbox.
I solved your problem and the code is as follows. I hope I have helped
By adding @ to the div tag, we can see the changes in the content of the tag in the change method. And in that 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>
And here we have the props created by $emit, whose value we initialize in the comment variable. Actually, it has a function 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>
