Create a method called 'requiredValues' that returns an array of all the values

After you've declared the function, you have to create a new array, then using a jQuery selector, you target all inputs with the "required" class name. Each of those elements are now part of a jQuery object, and we can use the each method to iterate over every element and execute a function on it.

What you want to do inside that function is add the value of the current element to the created array. An easy way to do that is by pushing the value onto the array. You can access the value by calling .val() on the current element, which is easily referenced using "$this". Don't forget to return your array.

var requiredValues = function()
{
     var myArray = new Array();
     $('.required').each(function()
     {
           myArray.push($(this).val());
     });
     return myArray;
}

Thank you, Sam! I finally had to copy and paste this question in to Google. I've watched the video about 17 times, but I seemingly met my match with this teaser.

Thanks again!

@Sam. This is very helpful! The video is quite hard to understand.

Gil David It's because they only want you to select the inputs with the class of '.required'. If there were any other input elements in the code, it will not be affected. Now if the '.required' class was used on other elements other than inputs then we would have a problem. But in this exercise it's pretty straight forward.

@Sam thanks very much for the explanation. I watched the video so many times but for some reason after reading your post it finally clicked. I kept adding a value equal to blank instead of just leaving it alone. I guess I was basing it too much off the vid.

Thank you

This was very difficult. I feel like the question does not even accurately ask what they are wanting us to do...

I'm having the same difficulty, the video explains very well what is being typed but I don't get the logic, why do that... Is the Jquery course for beginners (like me) who have no idea what is an array, a function, an each method, etc... ? Or is there another video we should watch first and only then the Jquery?

By the way, I love the treehouse videos and method, really helpful!!

I just don't understand one thing. when you choose the required class with the Jquery Selector $('.required') you should have selected the inputs too like this $('.required input')?

Gil won't that statement go one level below? Meaning that what will be selected is an input nested under a required class. This to me is different from selecting an input with class required.

Thanks for the explanation. The jQuery videos aren't helpful at all. They don't explain the underlying logic. I'm going to do the CodeCademy course and then return to finish this exercise.
