我收到未捕获的类型错误:未定义不是我网站页面上的函数。该功能在所有其他页面上都可以正常运行。它的页面代码有点冗长，所以我只会在需要时发布它，但这是基础知识。
弹出窗口的按钮:
<button class="btn btn-info" id="help" type="button" data-toggle="popover" data-trigger="focus" data-html="true" data-placement="bottom" title="ActiveMLS Documentation" data-content="<small><p><strong>List Custom Property Listings</strong></p></small>"><i class="fa fa-question-circle"></i></button>
错误
Uncaught TypeError: undefined is not a function shell.js:23
来自 shell.js 第 23 行的 jquery
/*******************************/
/* POPOVER HELPER
/*******************************/
$(document).ready(function(){
$('#help').popover()
});
我很困惑为什么它只在这个页面上中断？

最佳答案
还有其他要检查的东西。
如果您在 jquery.js 之前包含 bootstrap.js，也可能导致这种情况。
因此，请确保在 bootstrap 之前包含 jQuery。
在我的例子中，问题如下:
实际上我使用的是 pre-jQuery Rails，所以当我包含 Bootstrap JS 文件时，我不认为包含 jQuery 与它们捆绑在一起会导致任何问题，但是当我删除那个 JS 文件时，一切都开始正常工作。
Also one more possible case is, there could be multiple instances of jQuery in the page. So search for a duplicate version of jQuery and remove them if there is any.
这里有一个很好的链接可以看看。
