Problem Description
When I was learning javaWeb today, when I learned jQuery, I encountered a problem, which is probably like this:
I made a small case, mainly when implementing ajax asynchronous requests through jQuery, you need to import
jquery-3.3.1.jsfiles. The compiler I used at the time was IDEA. Therefore, I create a javaWEB project, and then configure the corresponding tomcat and path. Created a new folder under the webjsfolder. And write the corresponding code in the front-end page of jQuery's ajax, then start the project, and after entering the path, an error occurs: theUnCaught ReferenceError: Require is not defined。details are as follows:
Through Baidu , I found that I forgot to import the jQuery package on the front-end page, so I added the following code:
<script src="js/jquery-3.3.1.min.js"></script>
So I ran the code and found that GET http://localhost:8080/statics/js/jquery-3.4.1.js net::ERR_ABORTED 404an error was reported. The details are as follows:
Then I Baidu online, it turned out to be a problem with jQuery, so I did it according to the method introduced by weixin_45094098 , and it turned out good, I have to say that it is really amazing, I put I will share with you my solution.
problem solved
After importing jquery-3.3.1.min.js, you need to click Filethe button, then click Invalidate Cache/Restart..., then click the Invalidate and Restartbutton, Idea will restart, and invalid files will be filtered out. The specific process is as follows:
Then perform this step:
then restart the project, or refresh the page.
The background execution of this project is as follows:
