Checking if an element exists in current array

Question

I need to check through multiple paragraphs that contain input fields, i loop through each input field checking data has been entered, however i have groups of check boxes i need to check to see if at least one has been selected.

i have a loop through each input element and checking the parents are different, if not i am trying to store these in an array for validation later on, the problem i am having is the input filed with the same parent is still being added to the array and the value being stored is jQuery.fn.init[1].

$elementParent = $(currentElement).parent();
if(jQuery.inArray($elementParent, $checkboxArray) == -1)
{
   $checkboxArray.push($elementParent);
}

Further on in the code i get an error with the .each function, error given: Uncaught TypeError: $checkboxArray.each is not a function

$checkboxArray.each(function(index,checkboxParent){
$checkboxItems = checkboxParent.find('input[checkboxG=checkbox_group]');
$checkboxItems.each(function(index,item) {
if($(item.prop("checked")))
{
    $checkboxError = false;
}
});
if ($checkboxError == true)
{
   alert("error");  
}               
});

i have made a simple version of my error. https://jsfiddle.net/1b5ufnev/

because i am checking if 1 checkbox inside a group of checkboxes is selected as a minimum. — Bish25, Oct 25 '16 at 12:16

@adrianC yes the array is initialised and is adding the parents, however if the parents are the same it still adds. — Bish25, Oct 25 '16 at 12:23
https://jsfiddle.net/bd0f92ej/1/ each() function is not a standart function of an array. It's a jquery function so you should use $.each() — Adrian C., Oct 25 '16 at 13:13
i literally just solved it, thanks for your help but if you write an answer i can accept it — Bish25, Oct 25 '16 at 13:21
