Получить размер окна JavaScript
const window {
width: window.innerWidth,
height: window.innerHeight
}
Cheerful Cockroach
const window {
width: window.innerWidth,
height: window.innerHeight
}// better than using window.innerWidth / window.innerHeight
// because of scrollbars
const client = {
width: document.documentElement.clientWidth,
height: document.documentElement.clientHeight
}var win = window,
doc = document,
docElem = doc.documentElement,
body = doc.getElementsByTagName('body')[0],
x = win.innerWidth || docElem.clientWidth || body.clientWidth,
y = win.innerHeight|| docElem.clientHeight|| body.clientHeight;
alert(x + ' × ' + y);
