Jquery validate no punctuation and numbers

Question

I have a textfield for entering a name. No numbers or punctuation is allowed here. Only letters are allowed and dashes, also letters like é, è, à, ç, ...

Which regular expression do I need to use?

Answer 1

If the list of characters you want to exclude is small, you should probably use something like

[\d\.,;]

+ whatever other punctuation/non-word marks you want to exclude (`,',(,), etc seem like reasonable candidates, some of which will need to be escaped - probably should review a site like this for the whole shebang), and check that against your text. If it pops, fail the validation. The brackets above form what's called a character class or character set. The class will match anything that occurs between them once - more or fewer times if you apply a regex modifier (+, ?, ., etc).

Assuming you will add spaces and dash as you mentioned this should suffice your need.

Hope this helps and added image for your convenience.
