Prevent User From Editing Text in a TextBox using jQuery

I was recently solving a requirement where a TextBox having text needed to be made read-only, as soon as focus was set on it. This is a typical scenario where a user reloads a form that is to be presented as read-only. This is how I solved the requirement using jQuery:

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

    <script src="Scripts/jquery-1.3.2.js" type="text/javascript"></script>
    <script type="text/javascript">
        $(document).ready(function() {
            $("input[type=text]").focus(function() {
                if ($(this).val())
                    $(this).blur().css('background-color', 'gray');
            });
        });
     
    </script>
</head>
<body>
    <form id="form1">
    <div>     
        <input id="Text1" type="text" value="Some Text" />
        <input id="Text2" type="text" value="Some Text" />
        <br />
        <input id="Button1" type="button" value="Some Button" />
    </div>
    </form>
 
</body>
</html>

So as soon as you set focus on the textbox, the textbox turns grey indicating that it is read-only and the user is prevented to modify the text.
