15. Adding Logic to a Button Node

In order to add logic into our button node, we will add an inject node, a function node, and two change nodes. This will allow us to change the color and the icon of the button when pressed.

Next, double-click on the function parameter, type the following code and parameters

var state = context.state || false;
state = !state;
context.state = state;
if (state) { return [msg,null]; }
else { return [null,msg]; }
​

Click Done once completed

<i class="fa fa-rotate-90 fa-folder-open-o"></i> OPENED FEEDER
