Form Validation and Manupulation Challenge Task 2 - Help!

Hi Juan Pablo!

You can take a look at the code below. I added comments so you can see what each line does. Let me know if you have any questions!

-Andrew

function requiredValues() {

  //Get all of the .required tags
  var $required = $(".required");

  //Set array for return values
  var array = [];

  //Loop through .required tags
  $required.each( function () {

 //Add the values of each .required tag to the array
    array.push(this.value)
  })
  return array
}

This is the most difficult challenge I've encountered. Between the speed of the videos and the complicated instructions, this is taking me ages to get through. My frustration levels are through the roof.

Andrew K's answer did it for me. This was mostly infuriating because this topic wasn't covered in this video and hadn't been covered in ages.

Yeah! I wasn't taking the each method in account! Thanks...

In the third task they ask me: Create a method called 'containsBlanks' that returns true if any inputs with class 'required' has an empty string in, false if not.

I'm typing:

function containsBlanks() { var $required = $(".required"); $required.each(function() { $(this).val() == ""; }) }

But it doesn't work...

Thanks a lot for your help man!

I can't seem to get the code challenge to work for me to test it myself, but I believe you want to combine the ideas behind the isValidEmail and requiredValues methods. So you want to test each $required element and see if it has an index value for the empty string. If it does then push 'true' into an array and 'false' if not. Then you can use jQuery's sort() method (which sorts all false values first, then true values), and jQuery's pop() method to return the last value, which will be true if there was an input that contained blanks, and false if none of the inputs contained blanks. So something like

function containsBlanks () {
  var $required = $(".required"),
        array        = [];
  $required.each(function() {
    if (this.indexOf(" ") !== -1) {
      array.push(true)
    } 
    array.push(false)
  })
  return array.sort().pop()
}

Thanks man! Lot of help!!! Not working though :s

I've struggled to the point of reviewing the entire library of JS again trying to shake this challenge. Still can't get it! Tough!

Steve Leichman I completely agree. I spent a ton of time on this one and finally got it after seeing Andrew's response. This entire course set needs to be redone IMHO.

Yup, I am stuck and have been for a month now and I'm the kind of person who doesn't like to skip sections. So until I solve this, I can't allow myself to watch more lessons. HELP!

function requiredValues() {
  var $required = $(".required");
  var array = [];
  $required.each( function () {
            array.push($(this).val())
  })
  return array;
}

This is basically the same as Andrew K's and it will pass. Hang in there, Chalkley is super fast and difficult to follow, most of us will have to seek out some other basic learning to be able to comprehend js enough to follow jquery at this level. Google is your friend. I am reading eloquentjavascript.net right now to try and learn the foundations not covered in detail here.
