函数是crolledintoview（elem）{
var docViewTop=$（window.scrollTop（）；

您可以创建如下函数：
function isScrolledIntoView(elem) {
var docViewTop = $(window).scrollTop();
var docViewBottom = docViewTop + $(window).height();
var elemTop = $(elem).offset().top;
var elemBottom = elemTop + $(elem).height();
return ((elemBottom <= docViewBottom) && (elemTop >= docViewTop));
}
函数是crolledintoview（elem）{
var docViewTop=$（window.scrollTop（）；
var docViewBottom=docViewTop+$（window）.height（）；
var elemTop=$（elem）.offset（）.top；
var elemBottom=elemTop+$（elem）.height（）；
返回（（elemBottom=docViewTop））；
}
