Answer 1

Try below code.

change orderID to "order-id" in data(). "order_node.data('order-id') "

check undefined using typeof. "typeof order_node.data('order-id') === 'undefined'"

var order_node = $('div.oe_website_sale_tx_status');  
if (! order_node || typeof order_node.data('order-id') === 'undefined') {
    return;
}

HTML

<div class="oe_website_sale_tx_status" data-order-id="order.id">

</div>
