jQuery and Canvas.toDataURL

I'm working on a script, and a small part of that involves taking a canvas and converting it to a downloadable image. To do this, I do:

var thumb_jpeg = thumbnail.toDataURL("image/jpeg");
$("#" + options.dest).attr('src',thumb_jpeg);

...where thumbnail is a canvas tag and options.dest is the name of an img id.

This code works perfectly in Chrome, but when I try it in Firefox, Firebug throws up this error:

Security error" code: "1000
var thumb_jpeg = thumbnail.toDataURL("image/jpeg");

I would link to the whole script, but everything is hosted on my computer. Does anyone have any idea what this might mean?

Thanks! Jeff

Solution

  • I believe it may be because you have it hosted on your computer. Are you working directly from your local filesystem or are you working on a local server like MAMP or WAMP? I had this security code pop up on me before and it was alleviated when I moved my files from my hard drive on to a server.
