jQuery解决方案（假设所有元素都以某种方式定位）
$ b $ pre $ $'''$''。scrollTop（$（' #bar'）位置（）顶部）。。
编辑
bar 上设置 padding-top ，而不是 margin-如果您想在 foo 和 bar 之间放置一次空格，
编辑 DOM解决方案（适用于元素是否已定位，请参阅@cobbals回答jQuery等效项）：
document.getElementById（'foo'）。scrollTop + = document.getElementById（'bar'）。offsetTop - document.getElementById（'foo'）。 offsetTop
Let's say I have the following page:
<html>
<body>
<div id='foo' style='scroll:auto;height:400px'>
// content, content, content...
<div id='bar'></div>
// content, content, content...
</div>
</body>
</html>
What jQuery (or vanilla Javascript) can I use so that when the page loads, it jumps to #bar only within the div#foo (and not the entire page)? I don't need a fancy animation or scrolling, I just want #bar to be at the top of the div on page load.
jQuery solution (assumes all elements are positioned somehow)
$('#foo').scrollTop($('#bar').position().top);
EDIT
Side note: Make sure you set padding-top on bar and not margin-top if you want to put some space between foo and bar once its scrolled.
EDIT DOM Solution (works whether elements have been positioned or not, see @cobbals answer for a jQuery equivalent):
document.getElementById('foo').scrollTop += document.getElementById('bar').offsetTop - document.getElementById('foo').offsetTop
