Very easy from My side:-
<html>
<head>
<script
src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>
<script>
$(document).ready(function() {
$("input").click(function() {
$('<input type="text" name="name" value="value"/>').appendTo('#testdiv');
});
});
</script>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<div id="testdiv"></div>
<input type="button" value="Add" />
</body>
</html>
