jQuery and bind new values to dropdownlist using jQuery or clear items of dropdownlist using jQuery.


To clear dropdown values and bind new values to dropdownlist using jQuery we need to write the code like as shown below

<head>
<title>Clear dropdown values in jQuery</title>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script type="text/javascript">
function cleardropdown() {
// To clear dropdown values we need to write code like as shown below
$('#ddluser').empty();
// Bind new values to dropdown
$('#ddluser').each(function() {
// Create option
var option = $("<option />");
option.attr("value", '0').text('Select User');
$('#ddluser').append(option);
});
}
</script>
</head>
<body>
