jQuery validate plugin : accept letters only?

Question

I'm using the validate plugin from http://bassistance.de/jquery-plugins/jquery-plugin-validation/ What i'm trying to find is a way to make some of my form fields accept letters only, no numbers, special chars etc... Any idea people ? Thanks a lot.

Accepted Answer

Simply add a custom validator, and use it like this:

```
jQuery.validator.addMethod("accept", function(value, element, param) {
  return value.match(new RegExp("." + param + "$"));
});
```

Only numbers:

```
rules: {
  field: { accept: "[0-9]+" }
}
```

Only letters

```
rules: {
  field: { accept: "[a-zA-Z]+" }
}
```
