Form Validation and Manipulation, Checking Values, 2/3

Hi Page,

It looks like total.push($(this).val(); is missing a closing bracket so it should look like this total.push($(this).val());

Hi Adam,

Does J.T.'s explanation help? Are you still having trouble?

Hi Richard,

Could you post your code? There maybe a missing bracket too?

Regards Andrew

I've been struggling with this question too.

I'm not understanding the portion where I add the items to the array. Here is what I have so far:

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

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

Hey Adam,

The key points to understand in answering this question are as follows:

You should be know how to...

1. define a function in JavaScript & jQuery,
2. create a local variable inside of that function and know how to instantiate an array as its value,
3. use jQuery to select the content of fields whose class is "required" and add their values to the above mentioned array, and
4. have the function return the complete array of elements.

What seems to be giving you trouble? Do you have any code that you've tried to run?

Regards,

J.T.

I'm having a lot of trouble with this, too.

My "requiredValues" method looks like the one above from Page, down to every detail.

Does this differ greatly from the video lesson before, in that in the video we are only trying to see if a value is blank or not, and in this example, we are actually returning the values of a specific class?

Hey Andrew,

JT's explanation helps some, along with the other comments on the page. I just can't seem to get the very last part of the question down, returning the array.

Any suggestions?

Can you show your code? You can use codepen.io or use markdown in a post.

Hey I finally got it!!!

Here is what I did.

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

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

Thank you for the help everyone.

Thanks Andrew!

Here is my code so far (sorry, I don't yet know how to post code on here well):

function isValidEmail (email) {

  return email.indexOf("@") != -1;

}

function requiredValues ( ) {

  var required = $(".required");
  var correct = new Array( );
  $required.each(function( ){
    correct.push($(this).val( ))
  })

  return correct;
}

I have the right brackets (I think) but it still does not work, not sure if I am selecting and arraying the elements right.

Ack - nevermind! I forgot the "$" symbols before my variables.

There you go! :)

On a side, if you click on the markdown cheatsheet it tells you how to do code highlighting:

Code Indent your sentence with 4 spaces (or a single tab) to turn it into a code block.

I'll gone ahead and updated it for you :)
