Creating a mortgage calculator in Flash MX - Page 8

Functions

We'll need the following functions:

• CalculateRepayment - plays the calculate frame. Later, we'll add validation to this function.
• setRepaymentTerm - sets the value of the intRepayments variable
• StartOver - plays the first frame of the movie
• floor - used to round the repayment to two decimal places

function CalculateRepayment(component) {

   gotoAndPlay("calculate");

}



function setRepaymentTerm(component) {

   intRepayments = component.getSelectedItem().data;

}



function StartOver() {

   gotoAndPlay("start");

}



function floor(number) {

   return Math.floor(number*Math.pow(10,2))/Math.pow(10,2);

}

Test the movie. If you click the Calculate button, the second frame should display. Then you can click the New Calculation button to go back to the first frame.
