Checkbox selected triggers popup notification

[bhull]

I'd like to have a checkbox field named Multipstep, when selected, to trigger the default notification popup with a message I've configured. I don't see this as an available option in Actions, so I assume it requires JavaScript. Anyone know how I'd code this?

Solved my own problem. If anyone encounters this, the code I used was: 

if (event.target.value != "Off") { // box is checked app.alert("MY CUSTOM ALERT MESSAGE HERE");

}

else { // box is unchecked

}

I added a JavaScript "Mouse Up" action to the checkbox to display this alert. There may be a better way, but this seems to work for me.
