Ruby on Rails || Jquery和JavaScript库不起作用

前端之家收集整理的这篇文章主要介绍了Ruby on Rails || Jquery和JavaScript库不起作用前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我在Codepen上创建了一个页面,稍后将其添加到我的 Ruby on Rails应用程序( https://codepen.io/salman15/pen/evQVLV)中,其中所有代码都可以正常工作.

创建页面后,我尝试将页面添加到我的Ruby on Rails应用程序中,使用spree(在Cloud 9 https://consulegem-salman15.c9users.io/上运行“服务器在您阅读此内容时可能不会脱机”).我是用以下方式完成的:

第1步:将HTML代码添加到index.html.erb

第2步:将CSS CDN添加到_head.html.erb

第3步:下载所有JavaScript库并将其添加到以下文件夹路径中 – > app – >资产 – > javascripts – >前端 – >商店

第4步:将以下代码添加到我的all.js文件中(在frontend文件夹中)

//= require_tree

此时我的代码应该已经运行,但事实并非如此.

它让我觉得完全相同的代码与完全相同的库似乎不适用于我的Ruby on Rails应用程序,它为什么?

错误不是函数发生,因为代码无法识别,通常这是因为未加载库.然而,在加载了te页面并加载了所有库之后,我检查了源页面.

TweenMax错误也是我的幻想,因为它是相同的库和相同的代码.

我已经尝试了几种解决方案,比如将库代码添加到我的script.js中,它似乎有效,但这将是一个不正确的解决方案.

我想我已经都需要信息和代码了,但是如果你还需要更多信息和代码.

总结一下我的问题:

问题:我的Jquery库似乎不起作用

问题:为什么?

回答

您可以在下面的答案中找到答案,但这不是答案的唯一部分.答案的最后一部分是在CSS中,我的身体发生了冲突,造成了部分错误.因此,如果您遇到同样的问题,请确保您的库已加载到适当的位置(对我而言)和正确的顺序.还要确保您的CSS不会导致任何错误.

解决方法

根据您粘贴的文件,库的加载顺序错误.我怀疑应该将以下行移动到application.js清单的末尾,以确保仅在所有jQuery插件之后才加载它.就像是:
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .

请注意,require_tree不保证加载自定义脚本的顺序.因此,如果一个脚本依赖于另一个脚本,您仍然可以最终解决这些问题.您应该尝试编写独立脚本,以便执行顺序无关紧要.如果您绝对必须编写彼此依赖的脚本,那么您应该倾向于手动在清单中以正确的顺序导入它们.

此外,您导入看起来错误.您似乎已导入jQuery三次.你应该粘贴< head>的内容在开发模式下在最终呈现的页面标记以确保它实际上正在工作.

//= require_jquery.min <-- second import!
//= require_jquery-3.2.1.min <-- third import!
//= require_jquery.easeScroll
//= require_jquery.logosDistort.min
//= require_jquery.particleground.min
//= require_jquery.jquery.scrollmagic.min

尝试:

//= require jquery.easeScroll

当然,在将相关的宝石添加到Gemfile之后.
