jQuery to get Asp.Net DropDownList Selected item value,text and index

Introduction: In this article I am going to explain How to get DropDownList selected item’s Index, Value and Text using jQuery in asp.net.
jQuery to get Asp.Net DropDownList Selected item value,text and index

Description:  While working on asp.net project, it is very common requirement to get the Dropdownlist ‘s selected item’s index or value or text. 

For that we have dropdownlist attributes like "SelectedIndex" to get the selected item’s index, "SelectedValue" to get the selected item’s value and "SelectedItem.Text" to get selected item’s text. But if we want to get these using jQuery then below is the solution.

Implementation: Let’s create a simple asp.net web page to demonstrate the concept.

HTML Source Code

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Example to get DropDownList selected item index, value and text</title>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            $('#<%=ddlWeekDays.ClientID %>').on("change", function () {
                //Get DropDownlist selected item index
                var selectedIndex = $(this).find("option:selected").index();
                //Get DropDownlist selected item value
                var selectedValue = $(this).find("option:selected").val();
                //Get DropDownlist selected item text
                var selectedText = $(this).find("option:selected").text();
                $("#spnIndex").text(selectedIndex);
                $("#spnValue").text(selectedValue);
                $("#spnText").text(selectedText);
            });
        });
    </script>
</head>
<body>
    <form id="form1" runat="server">
        <div>
            <fieldset style="width: 380px; height: 150px;">
                <legend>Get DropDownList Selected item Index, Value and Text</legend>
                <table>
                    <tr>
                        <td>Select Day:
                    <asp:DropDownList ID="ddlWeekDays" runat="server">
                        <asp:ListItem Value="0" Text="Select"></asp:ListItem>
                        <asp:ListItem Value="1" Text="Monday"></asp:ListItem>
                        <asp:ListItem Value="2" Text="Tuesday"></asp:ListItem>
                        <asp:ListItem Value="3" Text="Wednesday"></asp:ListItem>
                        <asp:ListItem Value="4" Text="Thursday"></asp:ListItem>
                        <asp:ListItem Value="5" Text="Friday"></asp:ListItem>
                        <asp:ListItem Value="6" Text="Saturday"></asp:ListItem>
                        <asp:ListItem Value="7" Text="Sunday"></asp:ListItem>
                    </asp:DropDownList>
                        </td>
                        <td>Selected Index :
                        </td>
                        <td>
                            <span id="spnIndex"></span>
                        </td>
                    </tr>
                    <tr>
                        <td></td>
                        <td>Selected Value :
                        </td>
                        <td>
                            <span id="spnValue"></span>
                        </td>
                    </tr>
                    <tr>
                        <td></td>
                        <td>Selected Text :
                        </td>
                        <td>
                            <span id="spnText"></span>
                        </td>
                    </tr>
                </table>
            </fieldset>
        </div>
    </form>
</body>

</html>
