Sum of all TextBox values using jQuery

Here’s a simple script that sums up all textbox values using jQuery. Please note that I am not using any validation here to validate the data entered. The script simply shows how to sum up textbox values.

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>Sum of all TextBox values using jQuery</title>
    <script type="text/javascript"
    src="http://ajax.microsoft.com/ajax/jQuery/jquery-1.4.2.min.js">
    </script>
    <script type="text/javascript">
        $(function() {
            $("#addAll").click(function() {
                var add = 0;
                $(".amt").each(function() {
                    add += Number($(this).val());
                });
                $("#para").text("Sum of all textboxes is : " + add);
            });
        });
    </script>
</head>
<body>
    <input id="Text1" class="amt" type="text" /><br />
    <input id="Text2" class="amt" type="text" /><br />
    <input id="Text3" class="amt" type="text" /><br />  
    <input id="addAll" type="button" value="Sum all Textboxes" /><br />
    <p id="para" />
</body>
</html>
