Bootstrap modal won't show up
提问by Magnus Burton
My bootstrap (3.0.2) modal won't show up. I've tried different buttons, links and all that but it simply won't show up. I appreciate any help!
我的引导程序 (3.0.2) 模式不会出现。我尝试了不同的按钮、链接和所有这些，但它根本不显示。我感谢任何帮助！

UPDATE 1:Here's a screenshot of the warnings in the console.
更新 1：这是控制台中警告的屏幕截图。
UPDATE 2:The button and the modal are located inside a container. Maybe this could help on your path to a solution?
更新 2：按钮和模态位于容器内。也许这可以帮助您找到解决方案？

I solved this by adding this line of JQuery to the bottom of the page;
我通过在页面底部添加这行 JQuery 来解决这个问题；
<script>
$("[data-toggle='modal']").modal();
</script>

I think you need to put jquery and bootstraps javascript files path in the head of you html. I was having the same problem and this worked for me.
我认为您需要将 jquery 和 bootstraps javascript 文件路径放在 html 的头部。我遇到了同样的问题，这对我有用。
<head>
<link rel="stylesheet" href="plugins/bootstrap/css/bootstrap.css">
<!-- put first the jquery path, otherwise the bootstrap.js won't work-->
<script src="js/jquery/jquery-3.1.0.js"></script>
<script src="plugins/bootstrap/js/bootstrap.min.js"></script>
</head>
Hope it worked :)
希望它有效:)

I have the same problem. when i add this code :
我也有同样的问题。当我添加此代码时：
let postBody = event.target.parentNode.parentNode.childNodes[1].textContent;
modal will not show up . and when i remove it the modal appears.
模态不会出现。当我删除它时，会出现模态。

Adding this one line of code to the head solved the issue for me.
将这一行代码添加到头部为我解决了这个问题。
= javascript_include_tag 'application', 'data-turbolinks-track' => true
