In javascript, we usually have two ways to get the position of the scroll bar in the browser. Next, let us take a look at these two ways:

The first one: document. documentElement.scrollTop

This method is compatible with FireFox and IE browsers, but the value obtained for the Chrome browser is always 0.

Second type: $("body").scrollTop()

This method is compatible with chrome browsers, but the value in IE and FireFox browsers is always 0.

So the most accurate way to get the location is:

if($.browser.webkit) {
    scTop = $("body").scrollTop();
}else {
    scTop = document.documentElement.scrollTop;
}
