Although the most powerful part of Vue is component development, it is actually quite suitable for multi-page development. The following article is the example code of Vue that I will share with you to imitate Taobao checkout page. The main function is to imitate the settlement of Taobao page. This is a page that automatically calculates the total price when shopping for items in the shopping cart. I hope it can be helpful to everyone.
This demo is an updated demo based on the previous vue2.0 article on realizing full selection and inverse selection in the table. The main function is to automatically calculate the total when checking out the shopping cart items on the Taobao page. For the price page, please see the animation below for the specific page effect: (If you find any problems, please help Xiaoying correct the mistakes in time, thank you hehe)
