Use JQuery to implement a shopping cart similar to a shopping mall

Developer on Alibaba Coud: Build your first app with APIs, SDKs, and tutorials on the Alibaba Cloud. Read more ＞

 

Use the JQuery Clone template to display product information. You can modify the td in the template to determine how many items are displayed in each row.

Product Information is simulated using JSON data

If you click the same product multiple times, you will not add it again. Instead, the number of existing products is + 1,

You can also manually enter the number of items. If you enter 0, the item will be automatically deleted from the shopping cart (when you click the minus sign to less than 1, the system will also prompt whether to delete the item information from the shopping cart)

The price and total price of each product are calculated dynamically based on the addition and deletion operations.

Basic functions have been implemented. We recommend that you use IE6, and the browser run. Other Browsers Do not test the function.
