I am creating a simple HTML page to display some content in HTML page using javascript and I want to print the content from a drop down menu everything works but the page is refreshing when I print finishes and the ynamic data is disappeared from web page.

I tried

HTML

event.preventDefault();  and <a href="#" önclick="printReading(event);return false;">

etc but that disabled the dropdown menu from next operation.

My sample code is

HTML

<html>
	<head>
		<meta charset="utf-8">
		<title>Sample </title>
		<meta name="viewport" content="width=device-width,initial-scale=1.0">
		
	</head>
	<body>

		<div class="click-nav">
			<ul class="no-js">
				<li>
					<a class="clicker"><img src="img/i-1.png" alt="Icon">Options</a>
					<ul>
						<li><a href="#"   önClick="printReading(event);"><img src="img/i-2.png" alt="Icon">Print</a></li>
						<li><a href="#"><img src="img/i-5.png" alt="Icon">Help</a></li>
						
					</ul>
				</li>
			</ul>
		</div>
		
		
		<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
		<script>
		$(function() {
			// Clickable Dropdown
			$('.click-nav > ul').toggleClass('no-js js');
			$('.click-nav .js ul').hide();
			$('.click-nav .js').click(function(e) {
				$('.click-nav .js ul').slideToggle(200);
				$('.clicker').toggleClass('active');
				e.stopPropagation();
			});
			$(document).click(function() {
				if ($('.click-nav .js ul').is(':visible')) {
					$('.click-nav .js ul', this).slideUp();
					$('.clicker').removeClass('active');
				}
			});
		});

function printReading(event)
{
	var divElements = document.getElementById("printarea").innerHTML;
	var oldPage = document.body.innerHTML;
	document.body.innerHTML =
	"<html><head><title></title></head><body>" +
	divElements + "</body>";
	window.print();
	document.body.innerHTML = oldPage;
	//event.preventDefault();
}
function addDummyData()
{
	var table = document.getElementById('readings_table');
	var row = table.insertRow(0);
	var cell1 =row.insertCell(0);
	cell1.innerHTML ="Sample data";
}

		</script>
	<button onclick="addDummyData()">Click me</button>
<div id="printarea">
         <table id="readings_table"  width="100%" border="1" ></table>
</div>
	</body>
</html>
