Second button example

[natesrobot]

First off - this is the best example i could find yet!

Question -
When i try to add a second button with an additional method, I get an error saying:
TypeError: undefined is not a function (evaluating 'client.hi_nate())

I have added the function in the client.js file, but still get this error...
Could you provide an example with 2 buttons to show what code needs to be duplicated for each button? I would appreciate any help.

Thanks,

Nate

Did you follow the pattern for toggle_led? And are you using a javascript linter like ESLint to make sure there are no typos in your code?

Thanks! Turns out I was missing the comma after the toggle_led function where I added my second function...
Second issue i'm having is I cannot access the web page from any other device. (I know my network is ok since I'm connected to my raspberry pi through VNC Viewer)
The page that opens automatically from server.py works great, but not when I try through a different browser on the pi, or on another device.

Here's the console log when I run server.py (last two lines are when I try to connect from another device):

pi@raspberrypi:~/pi-websocket $ sudo python3 server.py

Network issues are outside of the scope of this code, so I can't help much. My only guess is to make sure you're entering everything in right, ie: http://my.pi.ip.addr:8000/.
