JavaScript: web export not working?

in Integration and Hardware • 8 months ago

I made a JavaScript program in Processing, and when I run it by clicking 'start server', it works fine.

But when I try to open "index.html" in the "web-export" folder, it doesn't work. It shows the page it normally would except the window in the center is empty instead of having the program in it like it should.

What is causing the problem and how can I fix it? Or am I doing something wrong (are you supposed to access the web export through the index.html created in the web export folder?)

There's a tendency nowadays for browsers to refuse running plugins and even JavaScript content
when a file is opened offline; that is, opened w/o using HTTP protocol!

However, Firefox ( Seamonkey, Waterfox, Palemoon, K-Meleon, etc.) still accepts such behavior.
Perhaps Opera too.
For other browsers, there may be ways to override this security restriction behavior.
But you have to search for it!

Hi all,

The same happens to me but I am still not able to run the script with neither Firefox nor Chrome. Is there any parameter I can modify in any browser to enable such feature?

I guess the workaround would be to put all the .pde code into the index.html file using the <script> label, would it work?

Thanks and brgds,

Firefox and all of its derivatives are the only 1s I know nowadays which allows to run JS and other plugins
from an offline .HTML file.

In Processing 1.5.1, press <CTRL+E> to export your program. Then <CTRL> + <K> to open that subfolder.
In Processing 2+, it's the same procedure. However, you need to be in JavaScript mode for it.

Once inside the created /web-export subfolder, right-click index.html file and force it to open through Firefox.
You can also drag the file into a Firefox's tab too.

If it runs through a server, it should run offline as well in Firefox!

P.S.: In Processing 1.5.1, it's exported as a Java applet rather than a JS program!

This is getting a bit crazy, I am able to run it locally from Firefox but not remotely (from Firefox too). If anybody can try, this is the webpage: http://jcarlosmartin.xtrweb.com/

I know it works through an applet since I tested it some months ago, but as far as I wanted my kids to play from a tablet/smartphone which does not support Java applets I tried the Javascript mode.

Thanks,
