limit field to char and dashes only

Is there a way to limit a field in html to only letters and dashes without scripting? I am trying to capture a field called “last name” and I do not want numbers or *()&^%$#@!+= or such. However, this form needs to be useable by anyone no matter their security regarding scripts. Any help?

Thanks

No, without scripting it’s just a box that sits there and accepts characters until maxlength is reached.

Of course, you will be validating the input when the page is submitted to the server, so if the user has disabled client-side scripting, you will catch it on the server and return the page to them for correction. (If you don’t do server side validation, your site most likely will not be secure.)

Well, HTML 5 is starting to be introduced by browser vendors and has support for regular expression filters:

To be honest I’m not sure what the state of play is right now with html 5 support in the major browsers – perhaps it is time for a bit of trial and error.
