Code Challenge Question: Checking Values

This is suppose to store all the values from required into an array and then return the array. It all looks like proper syntax to me. But, I don't know if i'm missing something? Please help.

var $require = $(".required");

function requiredValues ()
{
  var req = new Array();
  $require.each(function(){
    req.push($(this));
  });
    return req;
}


function isValidEmail (email)
{
 return email.indexOf("@") != -1;
}

He is talking about a jquery code challenge here (the one he is having problems with is task two).

It look like you are following the websites course, which is what I did in the beginning of learning Treehouse. Your probably not learning or remembering much which is what happend to me too.

Try following the Become a Web Designer Learning Adventure. After starting that everything made much more sense to me.

yeah I know it doesn't serve much of a higher purpose its just how they specifically defined the problem. I've done plenty of java coding, but I haven't quite gotten the syntax of javascript or jquery yet, but i'm hopeful. Thanks!

First, if you are referring to this week's JavaScript Validation challenge, which I think you are, you cannot use jQuery

You cannot use jQuery or any third party library to help you out. The code must be written only in JavaScript.

Anyways, lets get back to the question.

each() is a jQuery Object method. So, to use it you need to refer a method of jQuery object.

For your code, it will look like,

$($require).each(function(){...});

Here is a neat version of your code.

var require = $(".required");

function requiredValues(){
    req = [];

    $(require).each(function(index, element){
        req.push(element);
    });

    return req;
}

But I don't the see the purpose of your requiredValues() function. It just copies the content of the jQuery object, $require into a new array.
