当用户滚动“靠近”页面底部时，加载更多内容？

I use this to detect scroll to the bottom of page. But how do I detect a distance from the bottom of the page?

我用它来检测滚动到页面底部。但是如何检测页面底部的距离?

if($(window).scrollTop() + $(window).height() == $(document).height() ) {
 .. my ajax here
}

I mean i want the function to execute when he is 100px or 200px from the bottom, and not in the very bottom of page. How would I change this?

我的意思是我希望函数在从底部开始是100px或200px时执行,而不是在页面底部。我该如何改变?

Also: is it possible, to instead catch if the scroll is at the last of a specific element (say my big CONTAINER) which shows the loaded content.

另外:如果滚动位于显示加载内容的特定元素(比如我的大容器)的最后一个,则可能会捕获。

Thanks in advance

#1

var nearToBottom = 100;

if ($(window).scrollTop() + $(window).height() > 
    $(document).height() - nearToBottom) { 
 .. my ajax here 
}

or to scroll to the bottom of .CONTAINER

或者滚动到.CONTAINER的底部

if ($(window).scrollTop() + $(window).height() >= 
    $('.CONTAINER').offset().top + $('.CONTAINER').height() ) { 
 .. my ajax here 
}
