jQuery Checking Values Task3/3 from Build an Interactive Website

Having a bit of trouble with Task 3/3: "Create a method called 'containsBlanks' that returns true if an array of required values has any blanks in it, false if not."

This is what I'm trying so far:

function containsBlanks()
{
  var myArray = requiredValues(); 
  return (myArray.indexOf("''") > -1);
}

SOLVED: I was testing for the wrong string value inside of my indexOf; "" vs "''"

Edit: I also can't seem to get the Markdown to work, I'm putting 4 spaces in front of every code line, and it's still not taking? Is there a manual tag I can use?

Good to see you figured it out.

If you separate the line before the code example it will indent it correctly. I edited it for you. You should be able to edit and see what I did.

Hi Sam,

I'm stuck on the previous to this, Checking Values Task 2/3 from Build an Interactive Website.

Could you help please, I feel clueless on this.

Thanks!

Here's what I've done

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

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

I'm trying this same exact function as above but still not passing. Here's my whole code for this section:

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

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

function containsBlanks() {
    var myArray = requiredValues();
    return (myArray.indexOf("''") > -1);
}
