That is a browser restriction. You can remove the restriction with a browser specific incantation, eg for Chrome start it using the parameters `
allow-file-access-from-filesand/or
disable-web-security`. If you want to make it easy for others to just click an HTML file and have it work, you would need to inline the entire spine-widget.js in your HTML file.
Thank-you for your reply.
I added the entire spine-widget.js to the bottom of the html code between a <script type="text/javascript"></script> tag but am still getting the same browser restriction error. Should the .json and .atlas be inlined as well and how?
Yes, I should have mentioned you'll need to include the JSON and atlas data too. I've never actually done this, but you should be able to make it work!
I think there is something in the spine-widget.js that can be changed to point to local file resources as opposed to making an HTTP request but I'm not sure how to code that. It would be great to have an HTML export direct from Spine that can be used anywhere. A couple of other programs I've recently tried have this function but Spine's usability and features are much nicer. Thanks!
Spine uses XMLHttpRequest to load assets. This requires pointing at a URL, i.e. http://, https://, but also file://. Depending on the "browser" you use to view the local files, just specifying a file:// or relative URL might do the trick.
Hi. I'm still having trouble getting this to work locally outside of Firefox even when specifying a file:// path. Can I send you my test folder to have a look? I am hoping to have the animation play when the html file is dragged into a Safari window. This would be optimal in creating content for iBooks as opposed to using GIF or APNG. Many thanks.
Sure, send us your files via email. That said, iBooks does not support WebGL or Canvas, so it's unlikely this will work even if we can resolve the path issues.
Thank-you! I sent test files to contact@esotericsoftware.com. I included also an example using DragonBones where I imported Spine's Power-up animation (Powerup example) into DB then exported to HTML and assigned local assets. I was able to get the DragonBones HTML export to work locally in Safari and iBooks as well as Adobe Digital Editions. I think DB is using WebGL??
I want to do the same thing, how to use file://? I didn't find a way to work it locally.
I'm afraid file:// will not work with the web player. Resources need to be loaded through http(s).
Now I'm working on a larger project that uses a lot of content. And all this content has many stages of coordination. A convenient base is needed for the screening of all elements. A web player could handle this, but it turns out that everything works, you need hosting. It would be nice if it worked locally. 
As I understand it now there is no solution?
It's not up to us, it's how web browsers work. For security reasons they won't load local content. You can run a local web server very easily though. Eg if you have Python the command is python -m SimpleHTTPServer, described briefly here:

@Nate
Just analog dragon bones has such an opportunity. I don’t want to invent a bicycle in the form of local hosts or introduce people to Python.
I hope this opportunity will appear in the future. Thanks for the answer
It is possible using data URIs. I'll add an example to our GitHub repository.
