This article mainly introduces common error reporting problems when introducing files into the bootstrap jquery project. Below I will bring you some errors and error solutions. Friends in need can refer to

How to do a project Sometimes, various bugs will always appear in the console. In fact, there is no need to panic. There are only a few types of errors in the end. Every time you encounter an error during development, you are good at summarizing it. Next time you see it, you will be confident and know what the situation is. Well, the following are some errors summarized during the development process and their solutions.

Error 1: Uncaught ReferenceError: $ is not defined

Uncaught ReferenceError: $ is not defined
Uncaught ReferenceError: jQuery is not defined

Cause of error: File loading The order is wrong, the jQuery file must be in front

Method: Write the jQuery file in front of all script files

Error 2: Problem with relative path and absolute path of jsp page:

Normal path: ../../ in html, change it to jsp page The path cannot be found, and it looks like this at this time

At this time, you only need to add this code to the file:

Solution: Insert the following code between and

<%
 String path = request.getRequestURI();
 String basePath = request.getScheme() + "://"
   + request.getServerName() + ":" + request.getServerPort()
   + path;
%>
<base href="<%=basePath%>" rel="external nofollow" >

Error three: Uncaught TypeError: $(...). tooltip is not a function

Uncaught TypeError: $(...).tooltip is not a function
 at HTMLDocument.<anonymous> (app.js:42)
 at l (jquery.min.js:4)
 at Object.fireWith [as resolveWith] (jquery.min.js:4)
 at Function.ready (jquery.min.js:4)
 at HTMLDocument.S (jquery.min.js:4)

Reason: Includes two different versions of jQuery UI. This may cause conflicts. Try removing

<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script>

Solution:

Edit:

<script>
jQuery( document ).ready(function( $ ) {
 $(&#39;.hasTooltip&#39;).tooltip();
});
</script>

Use it like this, solved my problem!

Error four: Uncaught TypeError: $(...).sortable is not a function

Uncaught TypeError: $(...).sortable is not a function
 at HTMLDocument.<anonymous> (dashboard.js:12)
 at l (VM552 jquery.min.js:4)
 at Object.fireWith [as resolveWith] (VM552 jquery.min.js:4)
 at Function.ready (VM552 jquery.min.js:4)
 at HTMLDocument.S (VM552 jquery.min.js:4)

Error Five: bootstrap.min.js:7 Uncaught Error: Bootstrap requires jQuery

bootstrap.min.js:7 Uncaught Error: Bootstrap requires jQuery
 at bootstrap.min.js:7

Solution: Solution: Put jquery.min.js It doesn't matter if it is referenced before the bootstrap.min.js file, or the bootstrap.min.css file is referenced before or after the two files (tested multiple times).

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
