Ok...after a lot of experimentation, I've got a solution
that's working to the point that I've attempted to implement it.

Here's the code:

$(document).ready(function() {
                        
     $('input:text.required').each(function() {
          $(this).blur(function() {
               var val = (this.value.length);
                    if (val == 0) 
                         { $("#" + this.id + "_error").fadeIn(500);
                           $('#submit').attr('disabled', 'disabled'); }
                    else
                         { $("#" + this.id + "_error").fadeOut(500);
                           $('#submit').removeAttr('disabled'); };
                                                  
     $('input:text.required').each(function() {
          var val = (this.value.length);
               if (val == 0)
                    { $('#submit').attr('disabled', 'disabled'); }
     });
                        
          });
     });
});


This code allows for the following:

- on blur of any text input with class 'required' the length is checked
- if the length of the required field is > 0, then the error message is shown
  and the submit button for the form is disabled

- the second half of the code checks all the text inputs with class 'required'
- if the length of any of the required text fields is 0, then the submit button 
is disabled

What I need to do now:

- Allow for other type of inputs to be checked on blur, etc., such as selects
  (Later, I'll add other types of validation, such as numeric, etc.)

Question:

- How do I modify ('input:text.required') to accommodate other types of 
required inputs?
- I tried ('input:text.required, input:select.required') and
          ('input:text.required', 'input:select.required') but that didn't work

Clues or hints?

Thanks,

Rick
