Java Screen Field Validation

It has been a while since I had to do JavaScript in screens. And even longer since I done a validation on the screen. Since then there were changes in HR.Net which I have missed. And my old way to validate screens no longer works. But the fix is simple enough – all you need to do is add a parameter to the old script:

var orig_ValidatorOnSubmit = window.ValidatorOnSubmit;

window.ValidatorOnSubmit = function(validationGroup){
  var ErrMsg ='';
  var validate = true;
 
  // your custom validation goes here
	if (!validate){
          alert(ErrMsg);
		return false
	}
	return orig_ValidatorOnSubmit(validationGroup);
}
