vue模拟锚点定位加动画
//模拟锚点跳转
goAnchor(selector) {
let anchor = this.$el.querySelector(selector);
//document.documentElement.scrollTop = anchor.offsetTop;
let total = anchor.offsetTop;
// 平滑滚动,时长500ms,每10ms一跳,共50跳
// 获取当前滚动条与窗体顶部的距离
let distance = document.documentElement.scrollTop || document.body.scrollTop
// 计算每一小段的距离
let step = total/50;
(function smoothDown () {
if (distance < total) {
distance += step
// 移动一小段
document.body.scrollTop = distance
document.documentElement.scrollTop = distance
// 设定每一次跳动的时间间隔为10ms
setTimeout(smoothDown, 10)
} else {
// 限制滚动停止时的距离
document.body.scrollTop = total
document.documentElement.scrollTop = total
}
})()
