I am creating a comment box and I managed to append whatever I type to a div I wanted, however I have added another input and trying to append that along with the comments, however when I do this the second time, the previous duplicates. I know I’m doing something wrong in my display_commnents function, however I’m not entirely sure what it could be, basically I just want whatever is entered on both title and comments to append on the comment-box with title on top and comment just below. Below is my code:
<div class="container">
<h1>Write New Post</h1>
<form>
<input id="title" type="text" placeholder="Title" value="">
<textarea id="" placeholder="Leave us a comment" value=""></textarea>
<input id="giphy" type="text">
<div class="btn">
<input id="submit" type="submit" value="comment">
<button id="clear">Cancel</button>
</div>
</form>
</div>
<div class="comments">
<h2>Comments</h2>
<div id="comment-box" value="submit">
</div>
</div>
And this is my JS code:
const title = document.querySelector('#title')
const field = document.querySelector('textarea');
const textBackUp = title.getAttribute('placeholder')
const backUp = field.getAttribute('placeholder')
const btn = document.querySelector('.btn');
const clear = document.getElementById('clear')
const submit = document.querySelector('#submit')
// const comments = document.querySelector('#comment-box')
const titleText = document.getElementById('title')
const comments = document.getElementById('comment-box')
let title_arr = [];
let comments_arr = [];
title.onfocus = function(){
this.setAttribute('placeholder', '')
}
title.onblur = function(){
this.setAttribute('placeholder', textBackUp)
}
field.onfocus = function(){
this.setAttribute('placeholder','')
this.style.borderColor = '#333'
btn.style.display = 'block'
} // when clicking on this, placeholder changes into ' ', border colour changes and buttons will appear.
field.onblur = function(){
this.setAttribute('placeholder',backUp)
} //click away, placeholder returns
const display_comments = () => {
let list = '<ul>'
title_arr.forEach(title => {
comments_arr.forEach(comment => {
list += `<li>${title} <br>${comment}`
})
})
list += '</ul>'
comments.innerHTML = list
}
clear.onclick = function(e){
e.preventDefault();
btn.style.display = 'none'
title.value = ''
field.value = ''
display_comments()
}
submit.onclick = function(e){
e.preventDefault();
const head = title.value;
const content = field.value;
if(head.length > 0){
title_arr.push(head)
display_comments();
title.value = '';
}
if(content.length > 0){
comments_arr.push(content)
display_comments();
field.value = '';
}
}
any help would be appreciated
