/*向下滚动*/
if (distance < top) {
let small_interval = (top - distance) / 50
let i = 0
let timer = setInterval(() => {
i++
// console.log(distance += small_interval)
document.documentElement.scrollTop = distance
if (i == 50) {
clearInterval(timer)
}
}, 10)
}
/*向上滚动*/
else if (distance > top) {
let small_interval = (distance - top) / 50
let i = 0
let timer = setInterval(() => {
i++
// console.log(distance -= small_interval)
document.documentElement.scrollTop = distance
if (i == 50) {
clearInterval(timer)
}
}, 10)
}
=========>可以简写为下面的样式。
// top-distance,如果>0向下滚动,如果<0向上滚动,直接使用
let small_interval = (top - distance) / 50
// console.log(small_interval)
if(small_interval !== 0) {
let i = 0
let timer = setInterval(() => {
i++
distance += small_interval
document.documentElement.scrollTop = distance
if (i == 50) {
clearInterval(timer)
}
}, 10)
}
