Detect scroll down inside "body"
提问by Kim
I have an app inside a Facebook iframe and need to know when the user is scrolling down, inside the body. This code I have right now is only detecting the whole window. But I can't get it to work so it fires inside the body.
我在 Facebook iframe 中有一个应用程序，需要知道用户何时在正文内部向下滚动。我现在拥有的这段代码仅检测整个窗口。但我不能让它工作，所以它在体内燃烧。
Any ideas how I can modify this?
有什么想法可以修改这个吗？
//lastAddedLiveFunc();
$(window).scroll(function(){
var wintop = $(window).scrollTop(), docheight = $(document).height(), winheight = $(window).height();
var scrolltrigger = 0.95;
if ((wintop/(docheight-winheight)) > scrolltrigger) {
//console.log('scroll bottom');
lastAddedLiveFunc();
}
});

Try this:
尝试这个：
$('body').on('scroll', function (e){
if ($('#selector').has($(e.target)).length){
//do what you want here
}
});
I use this mostly for touch devices, but no harm in trying it out :)
我主要将它用于触摸设备，但尝试一下没有坏处:)
