1. Grab html source using javascript function
function getPageHTML(){
return "<html>" + document.getElementsByTagName('html')[0].innerHTML + "</html>";
}
2. Post this html source as parameter using jquery on click of pdfDownload.
printPDF is relative url i.e http:localhost:8080/Demo/printPDF
htmlString is post request parameter
$("#pdfDownload").click(function() {
//alert("Handler for .click() called.");
var fullHtml = getPageHTML();
$.post("printPDF", {
htmlString : fullHtml
});
});
3. Save html source to .html file and convert html to pdf using YAHP Converter. Here is example of action class of struts2.
package com.doctorAppointment.action;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;

import org.allcolor.yahp.converter.CYaHPConverter;
import org.allcolor.yahp.converter.IHtmlToPdfTransformer;
import org.apache.struts2.ServletActionContext;
public class PrintPDF {
private InputStream fileInputStream;
public InputStream getFileInputStream() {
return fileInputStream;
}
// configure fopFactory as desired
// private final FopFactory fopFactory = FopFactory.newInstance();
/** xsl-fo namespace URI */
protected static String foNS = "http://www.w3.org/1999/XSL/Format";
public String execute() throws Exception {
System.out.println("PrintPDF start");
HttpServletRequest request = ServletActionContext.getRequest();
String html = request.getParameter("htmlString");
String contextFolder = request.getServletContext().getRealPath("");
String htmlFileName = contextFolder + "\\download.html";
String pdfFileName = contextFolder + "\\download.pdf";
File htmlFile = new File(htmlFileName);
if (htmlFile.exists()) {
htmlFile.delete();
htmlFile.createNewFile();
} else {
htmlFile.createNewFile();
}
// save html
FileWriter htmlFileWriter = new FileWriter(htmlFile);
htmlFileWriter.write(html);
htmlFileWriter.flush();
htmlFileWriter.close();
// File pdfFile=new File(pdfFileName);
// new converter
CYaHPConverter converter = new CYaHPConverter();
// save pdf in outfile
File fout = new File(pdfFileName);
FileOutputStream out = new FileOutputStream(fout);
// contains configuration properties
Map properties = new HashMap();
// list containing header/footer
List headerFooterList = new ArrayList();
// add header/footer
headerFooterList
.add(new IHtmlToPdfTransformer.CHeaderFooter(
"<table width=\"100%\"><tbody><tr><td align=\"left\">"
+ "Generated with YaHPConverter.</td><td align=\"right\">Page <pagenumber>/<"
+ "pagecount></td></tr></tbody></table>",
IHtmlToPdfTransformer.CHeaderFooter.HEADER));
headerFooterList.add(new IHtmlToPdfTransformer.CHeaderFooter(
"© 2009 Quentin Anciaux",
IHtmlToPdfTransformer.CHeaderFooter.FOOTER));
properties.put(IHtmlToPdfTransformer.PDF_RENDERER_CLASS,
IHtmlToPdfTransformer.FLYINGSAUCER_PDF_RENDERER);
// properties.put(IHtmlToPdfTransformer.FOP_TTF_FONT_PATH, fontPath);
converter.convertToPdf(htmlFile.toURI().toURL(),
IHtmlToPdfTransformer.A4P, headerFooterList, out, properties);
out.flush();
out.close();
fileInputStream = new FileInputStream(fout);
return "SUCCESS";
}
}
