资 源 简 介
The JavaServer Pages (JSP) Expression Language (EL) is a
simple non-procedural scripting language that can be used
to evaluate dynamic expressions within a JSP page. Each EL
expression evaluates to a single value that is then expressed as
text in the output of the JSP (when used in template text), or
passed as a value to a JSP action.
As such, it is ideal for adding dynamic elements to the HTML
page (or other text output) generated by the execution of a JSP.
