Vertical scrolling not working in Ionic
提问by CaffGeek
I have two ion-scrollelements on my page, the top one scrolls horizontally, below it is a list that should scroll vertically.
我的ion-scroll页面上有两个元素，顶部一个水平滚动，下面是一个应该垂直滚动的列表。
The problem is it doesn't. It just bounces back to the top of the list.
问题是它没有。它只是弹回到列表的顶部。

I have found that if I set a height on the vertical ion-scroll it 'works' but this needs to work on multiple devices and I don't know what height to use. I'd prefer to not have to watch events, and recalculate the height each time. Anybody know how to fix this?
我发现如果我在垂直离子滚动上设置一个高度它“有效”，但这需要在多个设备上工作，我不知道要使用什么高度。我宁愿不必观看事件，而是每次都重新计算高度。有谁知道如何解决这个问题？

Here's a simple solution:
这是一个简单的解决方案：

Here's the meat of what we're doing:
这是我们正在做的事情的主要内容：
ion-scroll[direction=x] {
width: 100vw;
}
ion-scroll[direction=y] {
height: 100vh;
}
That will allow your scrolls to work as expected in your Ionic app (and, in fact, this is what I do in mine as part of the CSS boilerplate).
这将使您的滚动条在您的 Ionic 应用程序中按预期工作（事实上，这就是我作为 CSS 样板的一部分所做的工作）。

Hybrid work-around for you to try:
混合变通方法供您尝试：
Maybe it's not the best solution, but at least allows for scrolling, for you to try, if you like:
也许这不是最好的解决方案，但至少允许滚动，供您尝试，如果您愿意：
Just wrap your whole page content into a <div>with absolute position and define whether to scroll y and/or x:
只需将整个页面内容包装成一个<div>绝对位置并定义是否滚动 y 和/或 x：
<div style='position:absolute; top:0; right:0; bottom:0; left:0; overflow-y:scroll; overflow-x: hidden'>
<!-- your content of page here .... -->
</div>
Worked for me. Browsers compatibility on Windows 10, using ionic-package for Meteor JS (without Angular JS):
为我工作。Windows 10 上的浏览器兼容性，使用 ionic-package for Meteor JS（无 Angular JS）：
:-) shows scrollbar on: - FireFox - Windows 10 Edge - MS IE 11
:-) 显示滚动条： - FireFox - Windows 10 Edge - MS IE 11
:-( Does not show scrollbar, but it scrolls:- Safari - Chrome - Opera
:-( 不显示滚动条，但会滚动：- Safari - Chrome - Opera
Hope this helps a bit for some cases.
希望这对某些情况有所帮助。
