Question

I have the following in my code:

    <asp:DropDownList id="City" runat="server">

I tried using the following to get the key from the key value but it shows up as undefined although I selected from the dropdown

    var city = $("#city option:selected").val();

    alert(city);

Answer 1

You should simply use the .val() method on the select element itself, rather than searching for the option:selected child (as you’re currently doing). IDs in CSS are also case-sensitive.

var city = $("#City").val();
alert(city);
