jQuery web page height

问题

Let's say that a web page is twice the height of the browser window (thus there's a scroll bar). How do I retrieve the height of the web page in jQuery?

回答1:

$(window).height();   // returns height of browser viewport

$(document).height(); // returns height of HTML document

回答2:

You could use the height() of the document.

$(document).height();

回答3:

This can work also.

$('body').height();
