ICS3U1 Unit 1 Activity 5: Question 4

// Date Completed: July 12, 2017
// Purpose: Calculating body mass index based on measurements given using the metric or imperial system

// This line makes the button, btnRisk wait for a mouse click
// When the button is clicked, the determineBmi function is called
btnDetermine.addEventListener(MouseEvent.CLICK, determineBmi);

// This line makes the textinput, txtinLevel wait for a mouse click
// When a textinput is clicked, the clearLabel 1, 2, or 3 functions are called
// When a radio button is clicked, the labels for the measurements are changed
txtinMeasureA.addEventListener(MouseEvent.CLICK, clearLabel1);
txtinMeasureB.addEventListener(MouseEvent.CLICK, clearLabel2);
radMetric.addEventListener(MouseEvent.CLICK, changelabel1);
radImperial.addEventListener(MouseEvent.CLICK, changelabel2);

// This is the determineBmi function
// e:MouseEvent is the click event experienced by the button
// void indicates that the function does not return a value
