I have a bootstrap "form-group" that contains textarea and button form controls, I want to append the text which written inside the textarea to a list-group when button pressed
This is my page whith Jquery trial code :
$(document).ready(function() {
$('button:last').click(function() {
comment = $('textarea').val();
$('.list-group').append("<li class='list-group-item'>+comment+</li>");
});
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

you need to change
$('.list-group').append("<li class='list-group-item'>+comment+</li>");
into this $('.list-group').append("<li class='list-group-item'>"+comment+" </li>"); (careless mistake)
and add type="button"
$(document).ready(function(){
$('button:last').click(function() {
comment = $('textarea').val();
$('.list-group').append("<li class='list-group-item'>"+comment+"</li>");
});
});<html>
