List Items of a DropDownList using jQuery

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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

<
html xmlns="http://www.w3.org/1999/xhtml">

<
title>List Items of a DropDownList</title>
<
script type="text/javascript"
src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js">
</
script>

<
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>
<

<
form id="form1" runat="server">
<

<
select id="DDL">
<
option value="21">David</option>
<

<

<

</
select>
<

<
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.
