- All Implemented Interfaces:
- javax.servlet.jsp.tagext.IterationTag, java.io.Serializable, javax.servlet.jsp.tagext.Tag
- public class PrintPageTag
- extends javax.servlet.jsp.tagext.TagSupport
This class is a custom tag that renders the JWPPrintPage() Javascript
function which can be called to trigger a print dialog for the current page.
This tag uses the following attributes:
renderScriptTags - true/false - When set to true, the Javascript will be
rendered inside a <script> </script> tag pair. When set to
false, this will not be done and it is expected that the
<jstags:fullTrim/> tag appears inside a
<script> </script> tag pair. If this attribute is not present,
the script tags WILL be rendered.
It renders the following Javascript:
function JWPPrintPage() {
bv = parseInt(navigator.appVersion)
if (bv >= 4) {
window.print()
}
}
Usage example:
JWPPrintPage();
This will result in the print dialog being shown to the user so they can
print the current page.
