JSP syntax (1)--html annotations

js| Syntax HTML annotation

Displays a comment on the client.

JSP syntax

<!--comment [<%= expression%>]-->

Example 1

<!--This file displays the user login screen-->

Generate the same data as above in the client's HTML source code:

<!--This file displays the user login screen-->

Example 2

<!--This page is loaded on <%= (new Java.util.Date ()). toLocaleString ()%>-->

Displayed in the client's HTML source code as:

<!--This page is loaded on January 1,-->

Describe

This annotation is similar to HTML in that it can be seen in "viewing source code."

The only difference is that you can use an expression (shown in Example 2) in this comment. This expression is variable, different from the page, you can use a variety of expressions, as long as it is legitimate on the line.
