jquery form validation and manipulation challenge 3/3

Help! I've been stuck on challenge 3 forEVER. What am I doing wrong? Thank you..!!

Here's the challenge: Create a method called 'containsBlanks' that returns true if any inputs with class 'required' has an empty string in, false if not.

And here's my code:

function containsBlanks() {
  var blanks = new Array(); 
  $required.each(function() { 

            blanks.push($(this).val() == ""); 
  }); 

  return blanks.indexOf(true) != -1; 
};

Try this

function containsBlanks(){

  var vals = [];

  $.each($('.required'), function(){
    vals.push($(this).val());
  });

  return vals.indexOf('') != -1;

}

This helped me. But I've done exactly this, but I used $(".required input") selector instead of just .required. Weird code challenge.

Hi David,

You don't have a proper jQuery selector.

$('.required').each(function() {

Doing something like this would have been ok too:

var $required = $('.required');
  $required.each(function() {

You can find the answer into the video literally. Try this:

return blanks.sort().pop();
