The "struts-html-el" tag library contains JSP custom tags useful in creating dynamic HTML user interfaces, including input forms.
The functionality of this tag library is entirely provided by the base "struts-html" tag library in the Struts distribution. This derived tag library, "struts-html-el", only provides a different way to evaluate attribute values, which is using the JavaServer Pages Standard Tag Library expression language engine, or the "JSTL EL" for short.
The functionality of the "html-el" tags can be almost entirely understood from the documentation of the "struts-html" base tag library.
The following are discrete examples of uses of the "html-el" tags, in no paticular order, but emphasizing the use of JSTL EL values as attribute values.
Example:
<html-el:button onblur="handler('${arg}')" styleClass='${styleClass["button"]' titleKey='${titleKey["button"]}' value='${buttonValue["button"]}' />
Example:
<html-el:checkbox property="button" value="${flagValue}"/>
Example:
<html-el:link page="/doit.do" accesskey='${linkkey["doit"]}' > A link </html-el:link>
Example:
<html-el:link page="/doit.do" onclick="openModal('/editSalary.do?id=${employee.id}')" > A link </html-el:link>
