Comments disappear after refreshing site

I'm trying to make a simple comment system. It display comments, but when I refresh the page , all comments disappear, only to re-appear again when I add a new comment. I would like to see the comments even after refreshing the page. And preferably with time stamp and in reverse order: so latest on top.
const field = document.querySelector('textarea');
const comments = document.getElementById('comment-box');
// array to store the comments
var comments_arr = [];
if(!localStorage.commentData){localStorage.commentData = [];}
else{
comments_arr = JSON.parse(localStorage.commentData);
}
// to generate html list based on comments array
const display_comments = () => {
let list = '<ul>';
comments_arr.forEach(comment => {
list += `<li>${comment}</li>`;
})
list += '</ul>';
comments.innerHTML = list;
}
submit.onclick = function(event){
event.preventDefault();
const content = field.value;
if(content.length > 0){ // if there is content
// add the comment to the array
comments_arr.push(content);
localStorage.commentData = JSON.stringify(comments_arr);
// re-genrate the comment html list
display_comments();
// reset the textArea content
field.value = '';
}
}
html {
font-size: 14px;
font-family: "Open Sans", sans-serif;
background-color: rgb(239, 239, 238);

/*Comment section*/

}
<link href="comment.css" rel="stylesheet">
<form>
<textarea id="comment" placeholder="Your response pls." value=""></textarea>
</form>
<input id="submit" type="submit" value="add">
<h4>Responses</h4>
<div id="comment-box"></div>
<script src="comment.js"></script>

Adding window.addEventListener('load', display_comments) will fix
This will run the display_comments function on every refresh

You call display_comments after submitting a comment, but you don't call it anywhere else - it needs to be called when the page loads as well.

In fact I want when The user clicks submit button The Data passes To Asp.net core codes
Please help me, I have been involved in this issue for several days
Thanks

Binding model does not happen in your HTML that is sent to the action method with a submit . You can transfer array question and answer with Ajax.

I find the reason why you can't get the model in backend code.
Because the data you passed is string format, so we can installNewtonsoft.Json library. And deserialize the string to object.
public class list_questions {
public string question_sentence { get; set; }
public List<string> question_answers { get; set; }
}
STEPS
In your .cshtml, you code should like below.
<form action="/ForTest/get_data" id="all-questions-main" method="post" style="display: none">
<input type="hidden" name="data" id="questions-data">
</form>
My /ForTest/get_data method

Question on element alignment and how cursor is able to stay flush with the text in this editable code textarea?

Looking at this codepen, most of it I grok. But a couple of things I don't understand:
How does the <code> element stay perfectly on top of the <textarea>? I would expect it to be below the textarea looking at the HTML code.
How is the cursor staying so well-aligned with the text such that it functions like the type of cursor in a word document? The cursor even aligns well with the text when I copy and paste the text. Is it the emmet dependency that's helping?
Here is the code:
HTML
<div class="editor-holder">
<ul class="toolbar">
<li><i class="fa fa-indent"></i></li>
<li><i class="fa fa-expand"></i></li>
</ul>
<div class="scroller">
<textarea class="editor allow-tabs"><div class="Editable Textarea">
<h1>This is a fully editable textarea which auto highlights syntax.</h1>
<p>Type or paste any code in here...</p>
<div>
<?php
var simple = "coding";
?>
<script>
with = "Tab or double space functionality";
</script></textarea>
<pre><code class="syntax-highight html"></code></pre>

How does code and textarea elements stay aligned?
They are aligned because in the CSS they both use the same style which outlines the positioning of both elements. They both use position: absolute and the same top and left properties so stay in the same position.
See here https://www.w3schools.com/css/css_positioning.asp
In terms of the z-axis you can see that code has a z-index of 1 while textarea has 2 so text area stays on top.
How is the cursor staying aligned with the text?
There is no javascript acting on the cursor here. If you were to have any textarea in html the cursor would align with the text.

how to run javascript function 'live' without refresh?

im trying to make a average grade calculator, now thats is going fine but now i want to calculate the average immediately when a number gets inputted in one of the fields. I've been trying this with "on(), live(), onkeyup()" but can't get it to work.
The result of the average now displays beneath the inputfields 'onclick' on the button. I want the average displayed there but then as soon as you input numbers in one of the fields it should show there as it now does after the onclick.
What i've tryed with the 'on(), live(), onkeyup()' is to connect them to the input fields and connect them to the calculator() function.
Is there a easy way to do this or a other certain way?
greetings.

Using vanilla JavaScript I would attach an eventListener to the inputfields like this
document.getElementById('weight-1').addEventListener('change',function(){
calculator();
});
document.getElementById('mark-1').addEventListener('change',function(){
calculator();
});
These addEventListener functions adds listeners to the "input" field's predefined 'change'-events, and fires the calculator(); function from your code.
Seeing that you are using some sort of dynamic generation of the inputfields, you could add the listeners to your inputfields using the same querySelector that you use to target them during calculation. It would mean replacing getElementById('weight-1') in my example above with querySelectorAll('[id^=weight-]') for the weight-fields.
Also, doing work with values, IO, and calculation between html and JavaScript, I would suggest using a library like jQuery. jQuery simplifies these processes a lot.
This is the documentation for the jQuery alternative onClick function:
https://api.jquery.com/change/

I think you could do that with an angularJS module. Take a look at this tutorial : https://www.w3schools.com/angular/angular_modules.asp
maybe it will help.

My question is how can I transform this code into a responsive site.
Everything is resizing normally, except I cannot seem to resize my table and form. Could somebody help me?

A few things going on here.
First, you don't have a set width on a few of your fields, so change:
fieldset{
border: 0px dotted red;
width: 400px;
margin: 0 auto;
}
to:
fieldset{
border: 0px dotted red;
width: 400px;
margin: 0 auto;
max-width: 100%;
}
Also change .headerbar from width: 988px; to width: 100%;.
For responsive frameworks, you need to ensure that you never have a set a fixed width without ensuring there is a max-width attached to it, otherwise your content size will never drop below the size of your fixed width.
Second, I noticed the following:
.leftbar{
width: 50%;
background: #EB593C;
min-height: 605px;
float: left;
border-radius: 4px;
border: 3px dashed #282827;
}
You didn't specifically call this out, but when I check your code in a smaller view, I notice that your width: 50%; is causing the backgrounds to look off, which does not seem to be your intention. I would recommend adding .leftbar { width: 100%; } as well as .rightbar { width: 100%; } inside of #media screen and (max-width:700px){
That just leaves the table. Tables do not automatically break down, so are generally not something we want to use when developing a responsive site, but of course sometimes there is no getting around this.
There are a few ways to tackle the issue with the table. One is to set the table to display:block; and apply overflow-x: scroll; to it inside of your #media screen and (max-width:700px){, which will allow the user to scroll left/right when viewing it from smaller screens. Another is to use one of the various Javascript plugins that can achieve this.
Hope this helps get you on the right track. Best of luck!

Do not set width for these
input,select{/*width: 400px;*/}
fieldset{/*width: 400px;*/}
If you are setting width obviously you cannot obtain a responsive layout
