Oohh, tsk tsk tsk, another acute case of server addiction.
Don't worry, it's normal. Lots of people choose to write their dynamic WAP applications using server-side scripting. After all, this is what you've seen those "web application" developer types doing.
I have set up my clinic here at Yospace in order to show the world that you can, in some cases, wean yourself off that server. Do more on the handset and less on the server. How about writing your applications entirely in WMLScript? You may laugh, but you'll be surprised at what you can do, and you will also be surprised at how much faster your applications will seem to your users. Every time you avoid having to make a request back to the server, you save time!
In my clinic, you'll find some examples of WMLScript in action in some of the games found on Yospace's WAP site with some snippets of how these games work. I've also included my own recipe "code cures" which you should keep at hand for when your WAP applications start showing signs of unnecessary server dependency.

I've also set up a developer forum for swapping WML and WMLScript ideas. If you want to be a WMLScript Donor, email me at clinic@yospace.com.
Now relax and tell me if this hurts... |

Games |
Still don't believe the Doctor? Well, here is a list of the games that are available on the Yospace WAP site. All of these games uses minimal server
intervention and all of their logic is run in the handset as WMLScript. Try any of them out by clicking on their 'Play' icon. |

Yojack
Yospace’s implementation of the card game Blackjack.

Yozee
Yozee is much like the game of Yahtzee(tm). It's a sort of poker but with dice, not cards. The object here is to complete a score sheet with the highest point value as possible by rolling five dice. Three rolls of the dice are allowed, and on each roll you may hold any of the dice.

Code Cures |
Keep these remedies at hand, they might come in useful. You are free to use these snippets for your own WML pages. The Doctor prescribes these WMLScript snippets "as is", which means they are completely without warranty. This means if they cause your WAP application to fail, mobile phone to melt, or give you bad breath, the Doctor or Yospace cannot be held responsible. |

Email Validator
A function that checks whether a valid email address has been given. You would use this to warn users of erroneous entry before they submit their form to your server. Remember that you should always do the check on the server-side as well; the purpose of this code is to give the user feedback
sooner rather than later.
|
|
Date Validator
Enter a date and the program will check that the date is valid.
|
CODE! You can view the WMLScript code used to acheive this validation.

Bubble Sort
Bubble sort is a well known memory-efficient method for sorting things into an order. In this program, you can enter numbers, and they will be returned in ascending order.
|
|
Time zone
Enter the closest city to where you are now, the current time, and then select another city. The program will calculate what time it is in that other place. A trivial program that can provide the basis for your own time and time zone manipulation routines. I provide some helpful hints on how to alter this code to have it perform in different ways.
