This time I will bring you a detailed explanation of the use of the vue better-scroll scrolling plug-in. What are the precautions when using the vue better-scroll scrolling plug-in. Here are practical cases, let’s take a look.

What is better-scrollScrolling principle

better-scroll is a plug-in that focuses on solving the needs of various scrolling scenarios on the mobile side (PC already supported). Its core is based on the implementation of iscroll. Its API design is basically compatible with iscroll. On the basis of iscroll, it has expanded some features and made some performance optimization.

better-scroll is implemented based on native JS and does not rely on any framework. Its compiled code size is 63kb, 35kb after compression, and only 9kb after gzip. It is a very lightweight JS lib.

The green part is the wrapper, which is the parent container, and it will have a fixed height. The yellow part is content, which is the first child element of the parent container, its height will increase with the size of the content. Then, when content The height does not exceed the height of the parent container and cannot be scrolled. Once it exceeds the height of the parent container, we can scroll the content area. The principle of horizontal scrolling is to change the fixed height to a fixed width. (I won’t go into too much detail here)
