Changing Color of an Event

I’m trying to change the status of something to green if the channel is online, and have remain red if offline… How would I go about doing that in JQuery?

Here’s a link to my codepen:https://codepen.io/baquino1994/pen/EvLrPV?editors=1111

Thank you. I won’t be home for a couple of hrs. Would that work in this case? Could you perhaps test it. I believe I did something similar to no avail.
