为什么 body.scrollTop 不适用于 Google chrome 和 Firefox，但适用于 Microsoft Edge

Question

Previously body.scrollTop was working in my chrome.....but suddenly body.scrollTop is returning 0 in firefox and chrome......but returning proper value in Microsoft edge..

can anyone help me out?

Answer 1

Use document.documentElement.scrollTop to return scroll position value

Update: Use both

var value = document.body.scrollTop || document.documentElement.scrollTop;
