回答by Val
Try this...
尝试这个...
$('body,html').css('overflow','hidden');
$('body,html').css('overflow','hidden');
the ,htmlallows you to also include the <html>because some browsers may use that as the base as oppose to the <body>tag so it helps treating both as if they were one.
将,html让你还包括<html>由于一些浏览器可以使用它作为基地作为反对的<body>标记，以便它可以帮助标本兼治，好像他们是一个。
helpfulany tag should be selected like so $('a');or $('body');
有用的任何标记应选择像这样$('a');或$('body');
an element can be selected by idusing the prefix #so
可以id使用前缀来选择元素，#所以
<a id="c_1" >CLick Me</a>
<a id="c_1" >CLick Me</a>
$('#c_1');
or by classwith the prefix .
或通过class前缀.
<a class="classname">Click Me</a>
<a class="classname">Click Me</a>
$('.classname');
for more information read http://api.jquery.com/category/selectors/as for the scroll bars they are controlled by css, you could simply go on a css file and do the following.

Since nobody mentioned this, it's pretty easy to select the bodyelement without jQuery.
由于没有人提到这一点，所以body不用 jQuery就可以很容易地选择元素。
It's simply:
很简单：
document.body;
And based on your question, you would disable vertical scrolling by setting overflow: hidden:
根据您的问题，您可以通过设置禁用垂直滚动overflow: hidden：
document.body.style.overflow = 'hidden';
