javascript - Propper way of saving an admission ticket -

-

what state of art when comes saving admission ticket on mobile devices?

i have webseite , struggling problem when user finish checkout, find himself on overview of tickets bought.
clicking 1 of tickets gets ticketdetails barcode.
gets email site overview.

but customers asked me why there no possibility save tickets locally.
looked way html pdf. serverside , looks there no way javascript.

so there other options? maybe andoid/os onboard functions can use save sites images or that?

you can create generated pdf file saved data on server using javascript.

use premade library such jspdf http://code.google.com/p/jspdf/
