自定义单页滑块无法工作

A custom one-page slider is not working

本文关键字：工作 单页滑 自定义      更新时间：2023-09-26

我正在做一个单页的网站。你滚动/浏览网站的方式是通过一个自定义的"滑块"，由javascript工作。然而，问题是，页面没有像它应该的那样滑动。

有时当你加载页面时，它开始在中间集中。除此之外，有时当你滑动时，页面根本不滑动，有时它不向后滑动(等等)。

Uncaught ReferenceError: $body is not defined : /ivproject/achtergrond.htm:32

将$body更改为$('body')或将var $body = $('body');行添加到$(document).ready(function(){});块
