我有这个:
<script src="js/jquery.waypoints.min.js"></script>
<script src="js/jquery.waypoints.js"></script>
此:
.icon {
text-decoration: none;
border-bottom: none;
position: relative; /*puede ser acá */
opacity: 0.5;
}
另一件事:
.icon-animate {
opacity: 1;
}
最后这个:
var $first = $('.icon');
$first.waypoint(function (){
$first.addClass('icon-animate');
});
文件名称正确,属于正确的文件夹。为什么它不起作用?

使用waypoint编写函数的正确方法如下:
$first.waypoint(function(direction) {
$first.addClass('icon-animate');
});
然后,您可以指定选项:
// hit the top of your element when scrolling up
$first.waypoint(function(direction) {
if (direction == 'up') { // hit the top of your element when scrolling up
$first.addClass('icon-animate');
}
});
// hit the top of your element when scrolling down
$first.waypoint(function(direction) {
if (direction == 'down') { // hit the top of your element when scrolling down
$first.addClass('icon-animate');
}
});
// hit the bottom of your element when scrolling up
$first.waypoint(function(direction) {
if (direction == 'up') {
$first.addClass('icon-animate');
}
}, { offset: function() { return ((-$(this).height() + $("body").height())) } });
// hit the bottom of your element when scrolling down
$first.waypoint(function(direction) {
if (direction == 'down') {
$first.addClass('icon-animate');
}
}, { offset: function() { return ((-$(this).height() + $("body").height())) } });

请删除其中一个航路点js文件。它不能包括两者。
<script src="js/jquery.waypoints.min.js"></script>
<script src="js/jquery.waypoints.js"></script>
