Mods for server-less operation? (on Chromebook) #621

Open erantapaa opened 3 years ago

erantapaa commented 3 years ago

I am interested in running circuitjs without a web server -- i.e. the files are served directly from the file system.

The generated files in the war directory seem to work (given my limited testing) and I only ran into one small issue -- upon startup you get an error dialog saying that the circuits couldn't be loaded.

It's not a big deal since you can load them using the File -> Open File menu item. But I was just wondering if there are any other server interactions that I might get tripped up on.

(btw - I fixed the can't find circuits error message by just having getSetupList return immediately)

Did you see the offline version here: http://www.falstad.com/circuit/offline/

I think the only other issues you might see are that Export as Link may not generate useful links, and the locale files won't be loaded.

Hi - thanks, I should have mentioned that I want to run it on my Chromebook!

erantapaa commented 3 years ago

Ok, here's one issue I'm running into...

When trying to run jsinterface.html, it doesn't look like the main page can interact with the iframe. This callback doesn't seem to be executing:

iframe.contentWindow.oncircuitjsloaded = simLoaded;

and I'm getting CORS errors when trying to access into the iframe:

sim = iframe.contentWindow.CircuitJS1;

Might have to run a web server after all...

Here's a new idea... is there javascript code I can add to circuitjs.html to access the CircuitJS1 object?

pfalstad commented 3 years ago

Right, I don't think jsinterface.html is going to work. I'll look into making the simulator installable on a chromebook, which should solve these problems.

You should be able to access the CircuitJS1 object directly from circuitjs.html.

erantapaa commented 3 years ago

That would be great!

After playing around with it I figured out you can access CircuitJS1 from top-level JS code. GWT seems to blow away any hard-coded HTML elements you have on the page but I think I work around that.
