问为什么我的数组不能作为remove函数的参数？

EN

var lastid = 0;
var foods_added = [];
var locked = true;
function add_food() {
    var food_name = document.getElementById('food_name').value;
        $.ajax({
        url: "ask-info.php",
        type: "post",
        data: { food_name : JSON.stringify(food_name) },
        success: function(res) {
            console.log(res);
            if (res == "van") {
                var entry = document.createElement('h4');
                entry.appendChild(document.createTextNode(food_name));
                entry.setAttribute('id','item'+lastid);
                var removeButton = document.createElement('button');
                removeButton.appendChild(document.createTextNode("Töröl"));
                removeButton.setAttribute('onClick','removeName("'+'item'+lastid+', foods_added")');
                entry.appendChild(removeButton);
                lastid+=1;
                list.appendChild(entry);
                foods_added.push(food_name);
                document.getElementById('food_name').value = "";
                document.getElementById('press').disabled = true;
            } else {
                document.getElementById('press').disabled = true;
            }
        }
    })
}

function removeName(itemid, foods_added){
    var item = document.getElementById(itemid);
    for (var i = 0; i<foods_added.length; i++) {
        if (foods_added[i].id == itemid) {
            foods_added.splice(foods_added[i].id, 1);
        }
    }
    list.removeChild(item);
}
