One ...form... to rule them all?

I certainly wouldn't say this is insane and indeed I encourage it -- as long there aren't so many fields that the variables pane must scroll endlessly!

If you want a variable to disables all validation solely because the form might not include a fields for each corresponding Require* variable, that's unnecessary.  You can have the validation only apply to fields presently on the form. For example:

var formEl = form.getFormElem()[0],
allFields = [ 
{ 
  name : 'Company', 
  behaviors :  /* ... validators and other behaviors here */
}, { 
  name : 'FirstNames', 
  behaviors :  /* ... validators and other behaviors here */
}, 
{ 
  name : 'LastName', 
  behaviors :  /* ... validators and other behaviors here */
} 
],
fieldsPresent = fields.filter( function(itm){ 
  return !!formEl.querySelector('[name="' + itm.name + '"]'); 
});
// fieldsPresent now refers only to those fields that are present on the current form

You won't be able to combine all of the booleans into a multiple choice variable (well, not without some very fancy stuff I won't get into here). So everything that's an independent on/off switch needs its own variable. This is unfortunate, since the Enable and Require variants for the same field should really be a slider or radio button set (Off/Enable/Require).

If some fields will always be required if present (I would assume Email is one) then you can consolidate into one variable.

(jsvalidate) to toggle. Then I tried wrapping the script in something like "if (jsvalidate != false) { //validation code }, but it didn't work.

Variables are accessed using ${variablename}.

Validating a Select field. Right now, I just have a regex to check if it's not empty, for proof-of-concept, but I believe there's a better way to validate select fields. The ways I tried, didn't work, though - they killed the script.

I don't know why you'd need to validate anything other than non-empty, since the Select options are restricted at the form level and Marketo does the work of treating the first value ("Select...") as empty. If you want to restrict the values available to people, then you can remove certain options from the dropdown.

ok... so on the Select field, I can leave that as-is.

On the ability to include forms that might have fields not being validated by the javascript...

Looks like I'll have to hurt my brain learning how to rework the script. Just doing a quick glance... if I understand right, am I going in the right direction here? ( I suspect I'm not)
