Show Loading Gif When Customer Submits Order In Checkout

In checkout when a customer clicks to submit their order it takes awhile to process and load the confirmation screen. This is ok but I'd like to give some visual clue to the customer that the page is still loading so they don't abandon or try and resubmit.

I've disabled all third party plugins and seems to be because it sends an email to the customer on this order status.

I'd like to either show the existing loading gif that I have for other pages or change the text/style of the submit button while the order is processing.

Does anyone have any suggestions on what i could do here?

Thanks!

The default CS-Cart shows the ‘Placing the order’ loading box when placing an order.

I can't see any loading box - where in the code is this located?

Do you see loading box on other actions? For example, on adding product to cart?

When adding product to cart there's a loading .gif, it also shows when loading other stages of the checkout but not on submitting payment. (Am using old step by step checkout)

It should work on the checkout page as well. Additional code examination is required. Try to contact support team
