I have a verification function that checks my form fields if they have value
. if it doesn't it runs a string of things.

right now i have it to check 1 field.
function validateField(fieldname, labelname, longname) {
	longname = typeof longname !== 'undefined' ? longname : fieldname;
	
	if(document.getElementById(fieldname)) {
		if(document.getElementById(fieldname).value == "" || document.getElementById(fieldname).value == $('#' + fieldname).attr('placeholder') ) {
			 themessage = (themessage + longname+ '\n');
				
		}
	}
}

Open in new window

How can I use the same verification to if 2 fields are blank.
like this: if (document.form1.model.value=="" && document.form1.model1.value=="" ) {

function validateField(fieldID, labelname, longname) {
  longname = typeof longname !== 'undefined' ? longname : fieldID;
  var $field = $("#"+fieldID);
  if ($field) {
    if ($field.val() == "" || field.val() == $field.attr('placeholder') ) {
     return longname+ '\n');
    }
  }
  return "";
}

$(function() {
  $("#form1").on("submit",function(e) {
    var message = ""
    message += validateField("FieldID1",...);
    message += validateField("FieldID2",...);
    if (message) { 
     alert("Please fill in \n"+message);
     e.preventDefault();//cancel submission

My code will handle both fields if you give them an ID and call them like

   message += validateField("FieldID1","","long name");
   message += validateField("FieldID2","","long name");

It is called for you,

It is assigned to the submit of the form

Just replace your code with mine and fill in the missing stuff

"FieldID1","here","and here");
