Virtuemart JavaScript span id (cart subtotal)

Question

Is there a way that I can, in the cart, insert the cart subtotal into Google tracking code conversion value field?

How can I use jQuery to evaluate

<span id="tt_order_subtotal"><!--prints as £114.00 for example-->

from the virtuemart cart into a variable and thence to an integer.? I would be very grateful for just even a rough pointer?

Answer 1

var int_val = $('#tt_order_subtotal').text().match(/\d+/)[0];
