Hidden Tag

Used to render the HTML input type hidden element

Attributes: Common Attributes for HTML Tags are available

Example

<%@taglib prefix="lj" uri="/LJTagLib"%>
<lj:hidden name="jobPost" value="${param.id}" />

Include Tag

This tag has two uses:

It is used in a Site Template (a wrapper page) to indicate where to include the content of the page being visited.
It is used to include another JSP page stored on the platform. In that case, it can help to organize your pages. For example, common libraries can be declared on a single page--say, common.jsp. If that page is included everywhere, a new library can be added to every page simply by declaring in the common page.

Attributes

file	String	Specifies the content to include: `${_page}` in a Site Template `pages/{pageName}` in other pages, where pagename includes ".jsp"

Examples

Usage in a Site Template

<%@taglib prefix="lj" uri="/LJTagLib"%>
<lj:include file="${_page}" />

${_page} is dynamically replaced by the content of the page that is being visited.

Usage in other pages

<%@taglib prefix="lj" uri="/LJTagLib"%>
<lj:include file="pages/jbSearch.jsp" />

jbSearch.jsp is now included in the page.
