Simple examples of cookies and JS shopping carts

Recently learning native JavaScript, need to get a shopping cart function, below is a demo using cookies

The idea is actually very simple, the commodity interface through value to get the corresponding value, and then put the various information of this commodity into a dictionary, because there are multiple products, the dictionary objects of these products are placed in an array inside the line. This array is then serialized through JSON and stored in a cookie. In the shopping cart interface, you get this information by reading a cookie, and then dynamically create a table to display it.
