如何使用jQuery获取屏幕的高度[duplicate]
原标题:How to get the height of the screen using jquery [duplicate]

我想把某个东西放在屏幕中间

谢谢 (xiè xiè)

最佳回答
$(window).height();   // returns height of browser viewport
$(document).height(); // returns height of HTML document

按照此处记录:http://api.jquery.com/height/

问题回答

在响应式网站上使用(在手机或iPad上查看)

jQuery(window).height();   // return height of browser viewport
jQuery(window).width();    // return width of browser viewport

很少使用

jQuery(document).height(); // return height of HTML document
jQuery(document).width();  // return width of HTML document
$(window).height();

要将任何东西放置在中间,您可以使用CSS。

<style>
#divCentre 
{ 
    position: absolute;
    left: 50%;
    top: 50%;
    width: 300px;
    height: 400px;
    margin-left: -150px;
    margin-top: -200px;
}
</style>
<div id="divCentre">I am at the centre</div>
