提问by user970727
How can I use the scrolltop without an animation
如何在没有动画的情况下使用滚动条
This code works:
此代码有效：
var offTop = $('#box').offset().top;
offTop = offTop-43;
$('#mainCt').animate({scrollTop: '+=' + offTop + 'px'}, 400);
And here are my (not working solutions):
这是我的（不起作用的解决方案）：
$("#mainCt").scrollTop('+=' + offTop + 'px'); // doesn't work
$("#mainCt").scrollTop('+='+offTop); // doesn't work
hhh = setTimeout(' $("#mainCt").scrollTop('+offTop+');',800); // doesn't work

maybe if you don't want an animation or anything fancy just use an anchor
也许如果您不想要动画或任何花哨的东西，请使用锚点
<a name="top"></a>
Place it where you need to scroll
把它放在你需要滚动的地方
and in your function where you are calling use
并在您调用 use 的函数中
document.location.href="#top";
You could also create a function to append the anchor before the element, do the document.locationthing and later remove that anchor.
您还可以创建一个函数来在元素之前附加锚点，执行此操作document.location然后删除该锚点。

Try this:
尝试这个：
var offTop = $('#box').offset().top - 43;
$('#mainCt').scrollTop(offTop);
The scrollTopproperty accepts just an integer, no suffixes or units required.
该scrollTop属性只接受一个整数，不需要后缀或单位。

Skip jQuery. Just use JavaScript:
跳过jQuery。只需使用 JavaScript：
window.scroll(0, 0);

Why not use it with less duration. I fiddled it and it had no animation. SInce there will be no time to see the animation, there will be no animation at all.
为什么不以较短的时间使用它。我摆弄它，它没有动画。既然来不及看动画，也就没有动画了。
var offTop = $('#box').offset().top;
offTop = offTop-43;
$('#mainCt').animate({scrollTop: '+=' + offTop + 'px'}, 50); //50 added here as duartion

Can't you play with the duration ?
你不能玩持续时间吗？
var offTop = $('#box').offset().top;
offTop = offTop-43;
$('#mainCt').delay('800').animate({scrollTop: '+=' + offTop + 'px'}, 1);

var offTop = $('#box').offset().top;
$(window).scrollTop(parseInt(offTop))
