Javascript 平滑滚动到页面上的特定元素
我想在页面的开头有4个按钮/链接，下面是内容 我在按钮上写下以下代码：Javascript 平滑滚动到页面上的特定元素,javascript,jquery,animation,scroll,jquery-animate,Javascript,Jquery,Animation,Scroll,Jquery Animate,我想在页面的开头有4个按钮/链接，下面是内容 我在按钮上写下以下代码： <a href="#idElement1">Scroll to element 1</a> <a href="#idElement2">Scroll to element 2</a> <a href="#idElement3">Scroll to element 3</a> <a href="#idElement4">Scroll to el

编辑：和小提琴：你可以使用这个插件。这正是你想要的 平滑滚动-无需jQuery 基于此，我在没有外部库的情况下创建了一个 javascript非常简单。首先是一个辅助函数，用于改进跨浏览器支持，以确定当前位置
function currentYPosition() {
// Firefox, Chrome, Opera, Safari
if (self.pageYOffset) return self.pageYOffset;
// Internet Explorer 6 - standards mode
if (document.documentElement && document.documentElement.scrollTop)
return document.documentElement.scrollTop;
// Internet Explorer 6, 7 and 8
if (document.body.scrollTop) return document.body.scrollTop;
return 0;
}
function elmYPosition(eID) {
var elm = document.getElementById(eID);
var y = elm.offsetTop;
var node = elm;
while (node.offsetParent && node.offsetParent != document.body) {
node = node.offsetParent;
y += node.offsetTop;
} return y;
}
function smoothScroll(eID) {
var startY = currentYPosition();
var stopY = elmYPosition(eID);
var distance = stopY > startY ? stopY - startY : startY - stopY;
if (distance < 100) {
scrollTo(0, stopY); return;
}
var speed = Math.round(distance / 100);
if (speed >= 20) speed = 20;
var step = Math.round(distance / 25);
var leapY = stopY > startY ? startY + step : startY - step;
var timer = 0;
if (stopY > startY) {
for ( var i=startY; i<stopY; i+=step ) {
setTimeout("window.scrollTo(0, "+leapY+")", timer * speed);
leapY += step; if (leapY > stopY) leapY = stopY; timer++;
} return;
}
for ( var i=startY; i>stopY; i-=step ) {
setTimeout("window.scrollTo(0, "+leapY+")", timer * speed);
leapY -= step; if (leapY < stopY) leapY = stopY; timer++;
}
return false;
}
函数平滑滚动（eID）{
var startY=currentYPosition（）；
var stopY=elmYPosition（eID）；
var距离=停止>开始？停止-开始：开始-停止；
如果（距离<100）{
滚动到（0，停止）；返回；
}
var速度=数学圆（距离/100）；
如果（速度>=20）速度=20；
var步长=数学圆（距离/25）；
var leapY=stopY>startY？startY+step：startY-step；
var定时器=0；
如果（停止>开始）{
for（var i=startY；i stopY）leapY=stopY；timer++；
}返回；
}
对于（变量i=开始；i>停止；i-=步骤）{
设置超时（“窗口滚动到（0，+leapY+”），计时器*速度）；
leapY-=步长；如果（leapY平滑滚动到id为anchor-2的标题

scrollToItem（element）elementdocument.getElementById（'elementid'）requestAnimationFrame时非常平滑
对于平滑渲染的滚动动画，可以使用比常规的setTimeout（）
解决方案更好的方法
一个基本示例如下所示。为浏览器的每个动画帧调用函数step
，可以更好地管理重新绘制的时间，从而提高性能
