How to tell when you're at the bottom of a page:

if (  document.documentElement.clientHeight + 
      $(document).scrollTop() >= document.body.offsetHeight )
{ 
    // Display alert or whatever you want to do when you're 
    //   at the bottom of the page. 
    alert("You're at the bottom of the page.");
}

Of course you want to fire the above whenever the user scrolls:

$(window).scroll(function() {
    if (  document.documentElement.clientHeight + 
          $(document).scrollTop() >= document.body.offsetHeight )
    { 
        // Display alert or whatever you want to do when you're 
        //   at the bottom of the page. 
        alert("You're at the bottom of the page.");
    }
});

Here is a jsFiddle example that fades in a "You're Done! Scroll to Top of Page" link when the user has scrolled to the bottom of the page.

这将起作用,我在 IE 7、8、9、FF 3.6、Chrome 6 和 Opera 10.6 中对其进行了测试

$(window).scroll(function()
{
    if (document.body.scrollHeight - $(this).scrollTop()  <= $(this).height())
    {
        alert('end');
    }
});

如果上述解决方案不起作用,请检查您是否正确设置了文档类型:

<!DOCTYPE HTML>

我花了一个小时才知道:)

为避免重复console.log('end of page'),您需要创建一个 setTimeout,如下所示:

var doc = $(document), w = $(window), timer;

doc.on('scroll', function(){

    if(doc.scrollTop() + w.height() >= doc.height()){

        if(typeof timer !== 'undefined') clearTimeout(timer);

        timer = setTimeout(function(){
            console.log('end of page');
        }, 50);

    }

});

调试注意事项:我在使用 jquery-1.10.2.js 返回页面顶部时收到警报(?)。加载 jquery-1.6.4.min.js 一切都很好。

它可能需要调整以考虑浏览器,但应该这样做:

$(document).scroll(function()
{
    var $body = $('body');
    if (($body.get(0).scrollHeight - $body.scrollTop) == $body.height())
    {
        // display your message
    }
});

 <script>
    $(document).ready(function(){
         var a = 1;
         
         //this function triggers whenever scroll is detected
         window.addEventListener("scroll", function(){
            
           //this condition is used to trigger alert only once
            if(a == 1){  

                //this condition check whether user scrolled to the 
                //bottom of the page or not
                if(($(document).height()-2) <= 
                scrollY+$(window).height() ){
                     alert('end of the page');
                     a = 0;
                 }
            }
      })
    });
</script>
