Question

Suppose I have

$('#routingNumber').removeClass(validationClass('#routingNumber'));

(Where validationClass() is a regex that returns a class that determines the validation.)

Is there any way to trace that validationClass() was called on $(“routingNumber”) without explicity passing in the parameter #routingNmber

Phrased differently, is there anyway that the function validationClass() can know it should perform the regex on #routingNumber

I want to do this for ease of use, and in some cases it will be necessary.

Note: using $(this) as the parameter wont work, since the click event to remove the class is not bound to #rountingNumber

You would have to define a new function like this:

$.fn.removeValidationClass = function(){
    $(this).removeClass(validationClass($(this)));
    return $(this);
}

The value of $(this) will be the #routingNumber div in your example if called like this:

$('#routingNumber').removeValidationClass();
