Can I post an JS array to php via ajax, if button is pressed?

Question

I need to pass valuesArray to php if button is clicked, when anotherButton is clicked, i want to print this array in PHP.

home.js:

button.onclick = function (){

    valuesArray = ['a', 'b', 'c']

$.post('index.php', {data: valuesArray});
}

index.php:

<?php
    If(isset($_POST['anotherButton'])){
        $getData = $_POST['data'];
        print_r($getData);
    } 
?>

If button gets clicked I get

undefined index: data

which should mean that data wasn't passed to PHP.

$.post('index.php', {"data": valuesArray},function(return,result){});

Notice the double quote around "data".
Also may need to json encode valuesArray?
