嘿伙计们，我正在尝试实现 onscroll 功能，但它在我的网站上不起作用。
我究竟做错了什么？
<head>
<script>
$(document).ready(function() {
/* Every time the window is scrolled ... */
$(window).scroll( function(){
/* Check the location of each desired element */
$('.hideme').each( function(i){
var bottom_of_object = $(this).position().top + $(this).outerHeight();
var bottom_of_window = $(window).scrollTop() + $(window).height();
/* If the object is completely visible in the window, fade it it */
if( bottom_of_window > bottom_of_object ){
$(this).animate({'opacity':'1'},500);
}
});
});
});</script>
</head>
<body>
<div id="container">
<div class="hideme">Fade In</div>
<div class="hideme">Fade In</div>
<div class="hideme">Fade In</div>
<div class="hideme">Fade In</div>
<div class="hideme">Fade In</div>
</div>
</body>
