How do I determine height and scrolling position of window in jQuery?
I need to grab the height of the window and the scrolling offset in jQuery, but I haven’t had any luck finding this in the jQuery docs or Google.
I’m 90% certain there’s a way to access height and scrollTop for an element (presumably including the window), but I just can’t find the specific reference.
From jQuery Docs:
const height = $(window).height(); const scrollTop = $(window).scrollTop();
from http://api.jquery.com/height/ (Note: The difference between the use for the window and the document object)
$(window).height(); // returns height of browser viewport $(document).height(); // returns height of HTML document
$(window).scrollTop() // return the number of pixels scrolled vertically
There is also a plugin to jquery to determine element location and offsets
scrolling offset = offsetHeight property of an element
is more than 10x faster than jquery (and code has similar size):
