Here’s a script that lists items of a DropDown/Select Box using jQuery. I have used the map(callback) function for this requirement

<script type="text/javascript">
$(function() {
$("#btnList").click(function() {
var ddlItems = $("#DDL option").map(function(a, b) {
return b.text; // to print value say -- b.value
}).get().join("<br/>");
$('#para').html(ddlItems);
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<select id="DDL">
<option value="21">David</option>
<option value="22">Jack</option>
<option value="23">Jenny</option>
<option value="24">Julia</option>
</select>
<br />
<input id="btnList" type="button" value="Click Here to List Items" />
<br />
<p id="para" />
</div>
</form>
</body>
</html>
You can read more about Traversing/Map() . The get() function accesses all matched elements and passes it to map() as an array.
