Add TextBox value to DropDownList or Html SELECT using jQuery

You have a dropdownlist or an HTML Select with you. You now want to add additional options to the SELECT which you enter in the textbox, on the click of a button.
Here's how to do so using jQuery. The same technique can also be used for an ASP.NET DropDownList without causing a postback.

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

<head runat="server">

<title></title>

<script src="Scripts/jquery-1.2.6.js" type="text/javascript"></script>

<script type="text/javascript">

    $(document).ready(function() {

        $("#Button1").click(function() {

            $('#Select1').append($("<option>" + $('#Text1').val() + "</option>"));

            return false;

        });

    });     

</script>

</head>

<body>

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

<div>

    <select id="Select1" name="Select1">

        <option>Option1</option>

        <option>Option2</option>

        <option>Option3</option>

        <option>Option4</option>

    </select>

    <input id="Text1" type="text" />

    <input id="Button1" type="submit" value="button" />

</div>

</form>

</body>

</html>
