This article describes how to buffer the motion of JavaScript. Share it with you for your reference. The specific analysis is as follows:

The instance can be quickly started and then slowed down until it is stopped.

Key points:

var speed = (target-box.offsetLeft)/8;

The value of the target point minus the current position of the element is divided by 8, because the value of offsetleft keeps increasing, so the speed value also keeps decreasing.

speed = speed>0?Math.ceil(speed):Math.floor(speed);

Positive speed is rounded up, reverse speed is rounded down

Code:

<! DOCTYPE html>
