ruby on rails - How can I add page numbers to PDFKit generated PDFs? -


i have multiple pages generated using pdfkit. how can add page numbers bottom?

you need specify footer this:

kit = pdfkit.new(your_html_content_for_pdf, :footer_html => "#{path_to_a_footer_html_file}")

then in footer file have this:

<html>   <head>     <script type="text/javascript">       function subst() {         var vars={};         var x=document.location.search.substring(1).split('&');         for(var in x) {var z=x[i].split('=',2);vars[z[0]] = unescape(z[1]);}         var x=['frompage','topage','page','webpage','section','subsection','subsubsection'];         for(var in x) {           var y = document.getelementsbyclassname(x[i]);           for(var j=0; j<y.length; ++j) y[j].textcontent = vars[x[i]];         }       }     </script>   </head>   <body style="margin: 0;" onload="subst();">     page <span class="page"></span> of <span class="topage"></span>   </body> </html>

elements of classes 'frompage','topage','page','webpage','section','subsection','subsubsection' substituted appropriate data
