The best way to achieve this is using regular expressions.Alex– Alex2011-11-26 11:46:32 +00:00Commented Nov 26, 2011 at 11:46

let me make it clear ... you have an input type text and you want to use jquery to test whether the entered value is ''a'', ''b'', or ''c'' and in other cases alert something?Elwhis– Elwhis2011-11-26 11:48:05 +00:00Commented Nov 26, 2011 at 11:48

Do something like this:
$(document).ready(function() {
$("#yourInputId").keyup(function() {
if($(this).val() == "z") {
alert("You cant type this");
}
});
});

@user962408,
if( $(this).val().match(/[^abc]/) ) {alert("unallowed characters");}This is the link to allow Number and not alphabets (check the code here and make changes)....
Help your self finding out the key code for whichever alphabet you need to allow...
Here is the keycode

You can try use regular expression. example: http://www.9lessons.info/2010/01/jquery-validation-with-regular.html
or setup a powerful plugin like: http://bassistance.de/jquery-plugins/jquery-plugin-validation/
