Elastic_Grid | “未捕获的TypeError：无法读取未定义的属性'toLowerCase'”
[英]Elastic_Grid | “Uncaught TypeError: Cannot read property 'toLowerCase' of undefined”
问题描述
Putting together a personal & project portfolio, and trying to use Vu Khanh Truong's "elastic_grid" jQuery plugin for the actual portfolio. 
将个人和项目组合组合在一起，并尝试将Vu Khanh Truong的“ elastic_grid” jQuery插件用于实际组合。 You can view it here . 您可以在这里查看 。 The problem is that it seems to be causing the following errors on my page: 问题是它似乎在我的页面上导致以下错误：
1) I have a header for the portfolio section, and when I load the page with the plugin running, it makes my header disappear. 1）我有一个投资组合部分的标题，当我在运行插件的情况下加载页面时，它使标题消失了。
2) There're supposed to be filtering buttons that appear based on different tags used to categorize your content, and those don't appear. 2）应该有基于用于分类您的内容的不同标签而出现的过滤按钮，而那些按钮不会出现。
3) It loads the preview thumbnail images for the different categories I'm using, but when I click on them, it doesn't load the modal with the full-size images (and descriptions) as it's supposed to. 3）它加载了我正在使用的不同类别的预览缩略图，但是当我单击它们时，它并没有加载原本应该使用的全尺寸图像（和描述）的模态。
When I open the console in Chrome, I get this error: 在Chrome中打开控制台时，出现以下错误：
Uncaught TypeError: Cannot read property 'toLowerCase' of undefined
I tried creating a JSFiddle to post to replicate the problem I'm having, but I guess JSFiddle doesn't let you use certain scripts or something? 我尝试创建一个JSFiddle来发布以复制我遇到的问题，但是我想JSFiddle不允许您使用某些脚本或其他东西？ 'Cuz whenever I try to include all of the scripts I'm using on the page, it gives me MIME type errors in the console. “因为每当我尝试在页面上包括我正在使用的所有脚本时，它都会在控制台中给我MIME类型错误。
I've installed & am using the plugin according to the documentation, and I'm not the best at de-constructing Javascript, so I can't figure out why I'm getting these errors. 我已经按照文档安装并正在使用该插件，但是我并不是最擅长解构Javascript的人，所以我不知道为什么会出现这些错误。 :P If anybody can help, I would appreciate it. ：P如果有人可以提供帮助，我将不胜感激。

In Elastic_grid.js search for 'if(numOfTag > 1){ Creating the "Everything" option in the menu: createList("config.something"); 在Elastic_grid.js中搜索'if（numOfTag> 1）{在菜单中创建“所有”选项： createList（“ config.something”）; $.each(itemsByTags, function(I, i) { createList(I) })' $ .each（itemsByTags，function（I，i）{createList（I）}）'
and change the line in bold with createList("All"); 并使用createList（“ All”）;将行更改为粗体；
