我使用@ddanone answear并添加Ajax调用。

$('#mydiv').on('scroll', function(){
  function infiniScroll(this);
});

function infiniScroll(mydiv){
console.log($(mydiv).scrollTop()+' + '+ $(mydiv).height()+' = '+ ($(mydiv).scrollTop() + $(mydiv).height())   +' _ '+ $(mydiv)[0].scrollHeight  );

if($(mydiv).scrollTop() + $(mydiv).height() == $(mydiv)[0].scrollHeight){
    console.log('bottom found');
    if(!$.active){ //if there is no ajax call active ( last ajax call waiting for results ) do again my ajax call
        myAjaxCall();
    }
}

}

这是我的观点:

$('#container_element').scroll( function(){
        console.log($(this).scrollTop()+' + '+ $(this).height()+' = '+ ($(this).scrollTop() + $(this).height())   +' _ '+ $(this)[0].scrollHeight  );
        if($(this).scrollTop() + $(this).height() == $(this)[0].scrollHeight){
            console.log('bottom found');
        }
    });

根据Nick Craver的回答，你可以限制滚动事件，这样它就不会频繁地触发，从而提高浏览器性能:

var _throttleTimer = null;
var _throttleDelay = 100;
var $window = $(window);
var $document = $(document);

$document.ready(function () {

    $window
        .off('scroll', ScrollHandler)
        .on('scroll', ScrollHandler);

});

function ScrollHandler(e) {
    //throttle event:
    clearTimeout(_throttleTimer);
    _throttleTimer = setTimeout(function () {
        console.log('scroll');

        //do work
        if ($window.scrollTop() + $window.height() > $document.height() - 100) {
            alert("near bottom!");
        }

    }, _throttleDelay);
}

这是我的意见，因为公认的答案对我不起作用。

var documentAtBottom = (document.documentElement.scrollTop + window.innerHeight) >= document.documentElement.scrollHeight;

所有这些解决方案在Firefox和Chrome上都不适用，所以我使用Miles O'Keefe和meder omuraliev的自定义函数:

function getDocHeight()
{
    var D = document;
    return Math.max(
        D.body.scrollHeight, D.documentElement.scrollHeight,
        D.body.offsetHeight, D.documentElement.offsetHeight,
        D.body.clientHeight, D.documentElement.clientHeight
    );
}

function getWindowSize()
{
  var myWidth = 0, myHeight = 0;
  if( typeof( window.innerWidth ) == 'number' ) {
    //Non-IE
    myWidth = window.innerWidth;
    myHeight = window.innerHeight;
  } else if( document.documentElement && ( document.documentElement.clientWidth || document.documentElement.clientHeight ) ) {
    //IE 6+ in 'standards compliant mode'
    myWidth = document.documentElement.clientWidth;
    myHeight = document.documentElement.clientHeight;
  } else if( document.body && ( document.body.clientWidth || document.body.clientHeight ) ) {
    //IE 4 compatible
    myWidth = document.body.clientWidth;
    myHeight = document.body.clientHeight;
  }
  return [myWidth, myHeight];
}

$(window).scroll(function()
{
    if($(window).scrollTop() + getWindowSize()[1] == getDocHeight())
    {
        alert("bottom!");
    }
});

您可以尝试以下代码，

$("#dashboard-scroll").scroll(function(){
    var ele = document.getElementById('dashboard-scroll');
    if(ele.scrollHeight - ele.scrollTop === ele.clientHeight){
       console.log('at the bottom of the scroll');
    }
});
