[英]Prevent vertical scrolling beyond div
I am working on an Android app that makes use of HTML in a WebView
. 我正在使用在WebView
使用HTML的Android应用程序。
I have a series of <div>
s in my HTML. 我的HTML中有一系列<div>
。 Something like this: 像这样:
<body>
<div id='topdiv'></div>
<div id='contentdiv'>
<p>A bunch of content in here!<p>
<p>There is more content here than can fit on 1 screen.<p>
</div>
<div id='bottomdiv'></div>
</body>
Is there a way to make it so that bottomdiv
or topdiv
is rendered, but not scrollable? 有没有一种方法可以渲染bottomdiv
或topdiv
,但不能滚动? In other words, is there a way to prevent the user from scrolling down past contentdiv
even though bottomdiv
exists below it and is not invisible, but contentdiv
is always fully scrollable? 换句话说,是否有一种方法可以防止用户向下滚动通过contentdiv
即使bottomdiv
存在bottomdiv
下方并且不可见,但contentdiv
始终是完全可滚动的?
I am open to any plain JavaScript, CSS, or HTML implementation. 我愿意接受任何普通的JavaScript,CSS或HTML实现。 It would be nice if that was a feature you could turn on and off, but not necessary. 如果那是您可以打开和关闭的功能,但不是必需的,那就太好了。
Since I am working exclusively on a mobile device, it does not help me to disable the scrollbar or capture mousescroll
events and the like. 由于我只在移动设备上工作,因此它无法帮助我禁用滚动条或捕获mousescroll
滚动事件等。
If I understand well what you want, the following can solve your problem. 如果我了解您想要什么,以下内容可以解决您的问题。 Use the overflow property on the body tag, like this: 使用body标签上的overflow属性,如下所示:
body
{
overflow:hidden;
}
Another way to solve it would be to set your bottomdiv
to hidden
, either by using visibility:hidden;
另一种方式来解决这将是你的设置bottomdiv
来hidden
,或者通过使用visibility:hidden;
if you want it to take no space or using display:hidden;
如果您希望它不占用空间或使用display:hidden;
if you want it not to take any space. 如果您希望它不占用任何空间。 Than, just change it with javascript according to what you want to do. 比,只需根据您要执行的javascript更改它即可。
