The difference between JavaScript and jsp:

jsp technology is web The server-side technology of the website can be simply understood as jsp technology, which is used to generate dynamic web pages. Ordinary web pages are html, which are static and need to be written in html language in advance.

Then we add some java code to the html page and insert the dynamic content of the java code part into the original html page. Then, this page can become a jsp page. That is, jsp=htmljava.

Javascript is the client-side technology of the web. It is a scripting language that does not require compilation and is interpreted and executed by the browser. It is also inserted into the html page. The execution of javascript scripts is event-driven.

When the browser loads the HTML page and the user clicks on the button or text box on the page, if the page has written event JavaScript scripts for these buttons or text boxes, then the user is responding The execution of these scripts will be triggered when an action is taken. JavaScript scripts can respond to client actions without communicating with the server.
