Get window height on mobile devices (especially iPhones) without using jQuery

问题

All the answers on SO for fetching the device's height seem based on jQuery. We need something in pure JavaScript before the jQuery code loads.

回答1:

document.documentElement.clientHeight

There are a number of other methods, too: http://responsejs.com/labs/dimensions/

回答2:

May be a little late, but use window.screen.height

回答3:

In most cases, $(window).height(); does the job. However, on iOS, it gives wrong results because of the toolbars, same as $(window).outerHeight();. The right value to use is window.outerHeight.

Try this :

(typeof window.outerHeight != 'undefined')?Math.max(window.outerHeight, $(window).height()):$(window).height()
