is jquery plugin for a pure browser qrcode generation.
It allow you to easily add qrcode to your webpages.
It is standalone, less than 4k after minify+gzip, no image download.
It doesnt rely on external services which go on and off, or add latency while loading.
It is based on a library
which build qrcode in various language. jquery.qrcode.js wraps
it to make it easy to include in your own code.
Show, don't tell, here is a example
Let me walk you thru it. First include it in your webpage with the usual script tag
Then create a DOM element which gonna contains the generated qrcode image. Lets say
a div
Then you add the qrcode in this container by
jquery('#qrcode').qrcode("this plugin is great");
This is it. see it live.
You can set the height and width of the generated qrcode:
jquery('#qrcode').qrcode({width: 64,height: 64,text: "size doesn't matter"});
