EvaluationFormSample.js

//Step 1: For Debugging you can add this code to the console
FrontendApiManager.onReady("evaluationForm", function (api) {
   	window.api = api;
});


//Step 2: Get Variables bound to javascript objects
var question1 = api.getQuestion("howWellDidThisApplicantPerform");
var question2 = api.getQuestion("comments");

//Now bind the change event
question1.onChange(function(oldValue, newValue){
	if(newValue == "Did an Outstanding Job")
	{
		question2.hide();
	}
	else
	{
		question2.show();
	}
});
