Title: Front-end Vue imitates JD Taobao My Coupon List component for e-commerce App/mini program My Coupon List function page
I. Introduction
With the development of front-end technology, the complexity of applications is getting higher and higher. The traditional development method makes a system into a whole application. The addition or modification of a small function may cause changes in the overall logic, resulting in low development efficiency. and high maintenance costs. In order to solve these problems, front-end component development is receiving more and more attention. Through component development, a system can be split into a series of reusable independent components, which can be independently developed and maintained, and can be combined at will, which greatly improves development efficiency and reduces maintenance costs.
In the field of e-commerce, coupons are a commonly used marketing tool. In order to manage a large number of coupons, a coupon list page is usually created. This page requires frequent iteration and maintenance, so it is very necessary to use component development to build this page.
This article will introduce a front-end Vue imitating JD.com Taobao My Coupon List component for the e-commerce App/mini program My Coupon List function page, and discuss the technical implementation and advantages behind it.
2. Introduction to coupon list components
This coupon list component is mainly used for the My Coupon page of the e-commerce platform and is named cc-couponList. It receives three properties: theme color, coupon array, and item click event.

3. Technical implementation
The implementation of the coupon list component is based on the Vue.js framework. In Vue.js, we create a new component and define the corresponding properties and events. Then, the corresponding coupon list elements are dynamically generated based on the theme color and coupon array passed by the user. Each coupon element has a click event. When the user clicks, the corresponding event handler will be triggered.
