在页面加载时动画滚动到 ID [英] Animate scroll to ID on page load

问题描述

我想在页面加载时动画滚动到特定 ID.我做了很多研究，发现了这个:

Im tring to animate the scroll to a particular ID on page load. I have done lots of research and came across this:

$("html, body").animate({ scrollTop: $('#title1').height() }, 1000);

但这好像是从ID开始，动画到页面顶部?

but this seems to start from the ID and animate to the top of the page?

HTML(位于页面的一半)很简单:

The HTML (which is half way down the page) is simply:

<h2 id="title1">Title here</h2>

推荐答案

您只是在滚动元素的高度.offset() 返回元素相对于文档的坐标，top 参数会给你元素沿 y 轴的距离(以像素为单位):

You are only scrolling the height of your element. offset() returns the coordinates of an element relative to the document, and top param will give you the element's distance in pixels along the y-axis:

$("html, body").animate({ scrollTop: $('#title1').offset().top }, 1000);

您还可以为其添加延迟:

And you can also add a delay to it:

$("html, body").delay(2000).animate({scrollTop: $('#title1').offset().top }, 2000);
