สอบถามปัญหา การแยกคำที่เป็นตัวเลขด้วย split แล้วเก็บ array ครับผม

<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>

<div class="content">40|40|280|50</div>

$('.content').each(function() {
    var mydata = $(this).text().split('|').join(" ");
    $(this).text(mydata);

});

function merge_array(array1, array2) {
        var result_array = [];
        var arr = array1.concat(array2);
        var len = arr.length;
        var assoc = {};
    
        while(len--) {
            var item = arr[len];
    
            if(!assoc[item]) 
            { 
                result_array.unshift(item);
                assoc[item] = true;
            }
        }
    
        return result_array;
    }
