I have a form that is about 200 text fields.  Is there a way to use a general onblur / onfocus for all of them?  adding the same javascript for all of them is a pain in the .......

Yes, that's possible, using this code:

 

for (var i=0; i<this.numFields; i++) {
	var f = this.getField(this.getNthFieldName(i));
	if (f==null) continue;
	if (f.type=="text") {
		f.setAction("OnFocus", " // enter on focus code here");
		f.setAction("OnBlur", " // enter on blur code here");
	}
}

It's for a one-time use. You can run it from the JS Console, or even a button field.

Not possible. The script can't know if a field already has an action associated with it.
