在Javascript中等效于"window"的"element.scrollHeight"？

Question

什么是相当于element.scrollHeight为window纯香草的Javascript？我正在尝试将代码重写为目标window或document代替element？

转换这个: remaining = element.scrollHeight - (element.clientHeight + element.scrollTop);

进入: remaining = window.scrollHeight - (window.innerHeight + window.pageYOffset);

Answer 1

document.documentElement.scrollHeight
