Create an object from a class 257
Create an object from a class
You’ll create an existing class using visual tools (the TextField class) and
code (using the Date class).
1.
Open a new Flash document and change the name of Layer 1 to Text .
2. In the Text layer, create a dynamic text field and assign it the instance
name of
currentDate_txt
.
3.
Create an Actions layer.
With Frame 1 of the Actions layer selected, open the Actions panel.
4.
Create, or instantiate, an object from the Date class, named myDate :
var myDate:Date=new Date();
5. Create a variable called currentMonth equal to the
getMonth()
method:
var currentMonth:Number = myDate.getMonth();
6. Trace the value of
currentMonth
:
trace (currentMonth);
7. Save and test the document.
You should see a number in the Output panel that represents the
month.
The
getMonth()
method displays the current month. The
getMonth()
method is zero-indexed, meaning the numbering begins at
zero rather than one, so the number displayed is one less than what you
would expect.
8. Close the Output panel and the SWF file window.
