Question

Im using the bassistance form validation. I have a couple of fields that require digits only, but that excludes symbols like $,(,),-,*, etc from being allowed and i need these for fields like prices and phone numbers. Anyone know a method or plugin or something to work around this?

UPDATE

Basically, i need a function that says “no text allowed” and allowed symbols and numbers.

Another update

Found a function that doesnt allow text alone. But if there are symbols, it allows text as well. Any way to restrict any text?

jQuery.validator.addMethod(
  "symbols",
  function(value,element){
    var hNum=/[^a-z\s-]/;
    var inp=jQuery.trim(element.value).toLowerCase();
    if(hNum.test(inp)) {    return true;
    }
    else return false;
    },
    "Number and symbols are only allowed."
  );

According to their documentation, there’s already validation methods that can perform validation for: decimal numbers, digits and phone numbers

**EDIT: In that case it sounds like you want to create a custom validation. There is a method called addMethod which adds a custom validation with a call-back function like the one daGrevis created.

Example:

jQuery.validator.addMethod("isdigit", function(value, element) {
        return /[\d()-.\$]/.test(value); 
    }, "Numbers and symbols only allowed"
);
