JavaScript input saving and listed on the website

[kysminam]

<textarea rows="5" cols="30" id="txtArea"></textarea>
<input type="button" value="Click here" onclick="getText()" />

function getText() {
var str = document.getElementById("txtArea");
alert(str.value + " i did it");
}

I can see how html , css, javascript works but I would like to know how to save the user input on my website and listed like I am writing this post and saved in the list.

thank you

Everything saved on a site is with a database and a language to communicate with it. Your host should have a couple of DBs for you to use. I always choose MySQL. Once done the server side language is chosen. (some DBs don't/can't use all languages. ) I use PHP.

JavaScript has a special method of sending info to your server - the PHP program that will store things in the DB. The method is called Ajax. This can provide a two way street and the PHP can tell the user that things went well or that there is an error.
Simply use POST as the method and save the set up as a snippet in your coder. https://www.w3schools.com/js/js_ajax_intro.asp
