9. Comments and Character Quoting Conventions
There are a small number of special constructs you can use
in various cases to insert comments or characters that would
otherwise be treated specially. Here's a summary:
| Syntax |
Purpose |
<%-- comment --%> |
A JSP comment. Ignored by JSP-to-scriptlet translator.
Any embedded JSP scripting elements, directives,
or actions are ignored. |
<!-- comment --> |
An HTML comment. Passed through to resultant HTML.
Any embedded JSP scripting elements, directives,
or actions are executed normally. |
<\% |
Used in template text (static HTML) where you really want
"<%". |
%\> |
Used in scripting elements where you really want
"%>". |
\' |
A single quote in an attribute that uses single quotes. Remember,
however, that you can use either single or double quotes, and the
other type of quote will then be a regular character. |
\" |
A double quote in an attribute that uses double quotes. Remember,
however, that you can use either single or double quotes, and the
other type of quote will then be a regular character. |
%\> |
%> in an attribute. |
<\% |
<% in an attribute. |
