DarkxPunk Posted February 27, 2013 Share Posted February 27, 2013 Hey there, So the title may be deceiving, but I think this can be achieved using JavaScript. My goal is to have a QR code that runs a javascript. What will happen? Well my idea is that since not everyone scanning a QR code may have internet access at said time, it would be a great to have a failsafe. The failsafe would be, if there is a internet connection then go to url x, if not load a event card. In my head it seems simple, but I can't figure out how to achieve this. First off I know you can put as a url in the QR code to be "javascript:SomeJavaScript" but what is the power of that? Can I have it try to bounce off a server and if receive false to load the event card? Please any help is appreciated,Thanks. Link to comment Share on other sites More sharing options...
