我一直在寻找答案，但还没有找到确切的答案。这是一个纯javascript解决方案，与最新的Firefox, IE和Chrome在这个答案的时间:

// document.body.scrollTop alone should do the job but that actually works only in case of Chrome.
// With IE and Firefox it also works sometimes (seemingly with very simple pages where you have
// only a <pre> or something like that) but I don't know when. This hack seems to work always.
var scrollTop = (document.documentElement && document.documentElement.scrollTop) || document.body.scrollTop;

// Grodriguez's fix for scrollHeight:
// accounting for cases where html/body are set to height:100%
var scrollHeight = (document.documentElement && document.documentElement.scrollHeight) || document.body.scrollHeight;

// >= is needed because if the horizontal scrollbar is visible then window.innerHeight includes
// it and in that case the left side of the equation is somewhat greater.
var scrolledToBottom = (scrollTop + window.innerHeight) >= scrollHeight;

// As a bonus: how to scroll to the bottom programmatically by keeping the horizontal scrollpos:
// Since window.innerHeight includes the height of the horizontal scrollbar when it is visible
// the correct vertical scrollTop would be
// scrollHeight-window.innerHeight+sizeof(horizontal_scrollbar)
// Since we don't know the visibility/size of the horizontal scrollbar
// we scroll to scrollHeight that exceeds the value of the
// desired scrollTop but it seems to scroll to the bottom with all browsers
// without problems even when the horizontal scrollbar is visible.
var scrollLeft = (document.documentElement && document.documentElement.scrollLeft) || document.body.scrollLeft;
window.scrollTo(scrollLeft, scrollHeight);

window.onscroll = function(ev) {
    if ((window.innerHeight + window.scrollY) >= document.body.offsetHeight) {
        // you're at the bottom of the page
    }
};

看到演示

我为移动设备和桌面尝试了这个功能，这对我来说是工作，这里的一些评论在移动/Android设备上不起作用，顺便说一句，谢谢你的问题。程序员们，坚持下去吧!

    window.addEventListener("scroll", function(el) {
    const scrollY = window.scrollY + window.innerHeight + 2;
    const bodyScroll = document.body.offsetHeight;

    console.log("Scroll Y : " + scrollY);
    console.log("Body : " + bodyScroll);

    if(scrollY >= bodyScroll){
      alert("Bottom Page");
    }
  })

最简单的方法使用香草javascript

container.addEventListener('scroll', (e) => {
  var element = e.target;
  if (element.scrollHeight - element.scrollTop - element.clientHeight <= 0) {
    console.log('scrolled to bottom');
  }
});

我必须想出一种方法(在Java中)，系统地向下滚动，寻找我不知道正确XPath的组件(说来话长，所以就随它去吧)。正如我刚才所说，在寻找组件时需要向下滚动，并在找到组件或到达页面底部时停止滚动。

下面的代码片段控制向下滚动到页面底部:

JavascriptExecutor js = (JavascriptExecutor) driver;
boolean found = false;
long currOffset = 0;
long oldOffset = 0;
do
{
    oldOffset = currOffset;
    // LOOP to seek the component using several xpath regexes removed
    js.executeScript("window.scrollBy(0, 100)");
    currOffset = (Long)js.executeScript("var offset = window.window.pageYOffset; return offset;");
} while (!found && (currOffset != oldOffset));

顺便说一下，在执行此代码片段之前，窗口会最大化。
