jQuery Waypoint无法正常工作 [英] jquery waypoint is not working

问题描述

根据下面编写的代码，我认为当我滚动到.onscrollActivate div警报时，应该会出现.但这并没有给我警报.

As per my code written below I think when I scroll to the .onscrollActivate div alert should come. But it is not giving me the alert.

<div class="waypoint" style="width:100%;height:300px;"></div>

$(document).ready(function(){
    $('.onscrollActivate').waypoint(function() {
    alert();
  });
});

如果我改用.click()，它会给我警报消息.所以我的jquery很好.

If I try .click() instead, it gives me the alert message.so my jquery is fine.

那么，我要去哪里错了?

So, where am I going wrong?

推荐答案

您看到console中的waypoint is not a function错误，表明您尚未在页面上加载waypoint库.

As you see waypoint is not a function error in console, you haven't loaded the waypoint library on your page.

在jQuery之后的页面上包含waypoint js.

Include waypoint js on the page after jQuery.

<script src="https://cdnjs.cloudflare.com/ajax/libs/waypoints/2.0.5/waypoints.min.js"></script>
