SCRIPT:

<script type="text/javascript">
	$(document).ready(function() {
		$(".emoji-wysiwyg-editor").keydown(function (e) {	
				// alert(e.keyCode)
			if (e.keyCode == 13) {
					// alert(e.keyCode)
				var mystring = $(this).attr('data-emoji');
				id = mystring.replace('comment-form', '');
				id = $.trim(id);
				a = id;
				var b = $.trim($("#comment-form" + a).val());
				var c = $(this).attr('data-emoji');
				// var b = document.getElementById("comment-form" + a);
				alert(c);
				if (b != '') {
										
					$(this).html('');
					$.ajax({
						type: "POST",
						url: domain + "post/comment",
						data: "id=" + a + "&comment=" + (b),
						cache: false,
						success: function(b) {
							
							count = $('#count_comments_' + a).html();
							
							$("#comments-list" + a).append(b);
						
							$('#count_comments_' + a).html(Number(count) + Number(1));
							$("#comment-form" + a).val("");
							
						}
					});
				}
			}
		});
		$('#add_post').on('click', function() {
			$('#multiple_upload_form').ajaxForm({
