Write a class in the afternoon, format the date-name SimpleDateFormat. Let's take a look, exchange. Healing: A class simpleDateFormat in Java, when constructing an object, the way to display the display, you can get this format of the current date through a method of this class. Think about the function in Flash, there is no such function. Every time I have to get the date, I want to call the N methods in Date. The last string is pigureder to get the desired format, I feel trouble, start my brain, write this class.
Use: Write VAR SIM = New SimpleDateFormat ("YYYY / MM / DD") in Flash; then a date object var Date = new date (); then format the DATE, call the method and display: TRACE (Sim.Format (Date) This can get the date of such YYYY / MM / DD 2004/07/03, if you write VAR SIM = New SimpleDateFormat when constructing the SIM object ("YY / MM / DD "); you can get the date of such YY / mm / DD 04/07/03, as long as you want what format, just write his format when constructing the SIM object. That is, the date of separation, and display methods can be arbitrarily specified by you. Here, y said YY, YY indicates that 2 digits, yyyy shows all, m indicates the month, you must use the MMD to represent the day, if you don't want the day, you can not Write it, for example, don't have years, only the month can be like this to be like SimpleDateFormat ("mm / dd");
The specific code is as follows, everyone discusses, what is wrong, I will correct it again, write a detailed tutorial again, and provide this class to everyone, a class we develop, I use it, huh, huh. I will also write some kinds of classes, I hope that my friends who are interested will pay attention.
