Native JavaScript implements the scroll bar effect, javascript scroll bar

This article provides examples to illustrate how native JavaScript implements the scroll bar effect and share the Code with you for your reference. The specific content is as follows:

The entire object is constructed to prevent various messy data from polluting global variables. In addition, all the functions called inside the object are written into the object constructor. Due to the principle of the object scope chain, external calls cannot be performed, preventing accidental calls.
