Achieve the goal

1. The page starts counting down as shown in Figure 1 (you can click the cancel order button and the payment page disappears).

Second, the countdown is over and the deletion order appears.

Third, click Delete Order, and a pop-up box will pop up asking if you want to actually delete the order.

Four, click OK to delete the order.

JavaScript high imitation Alipay countdown page and code implementation

As shown in the picture above, all the source codes are given here (if you want to run, you only need to modify the CSS path and JS path introduced in the EJS file).
This page is actually something I wrote in my spare time.

But it involves related knowledge about countdown, pop-up boxes, and font diagrams (you can refer to the "How to Make Font Diagrams" chapter).

Share it here, I hope everyone can learn the knowledge you want from it.

The code is ugly, but the basic effects have been achieved.
