[TYPO3-dev] FYI - ACE

[Johannes Reichardt]

Hi Elmar,

i had a quick look at xajax - maybe its best i show you how to use ACE 
so you see the difference.

1. have normal php class with simple returns (no registering or 
including of any ajax wrapper or parsing data in a specific way)
2. this class is only adjusted to have a "methodtable" (an array like 
realurl on top ;) which defines which types of data may be passed to the 
method - this is for security

thats the whole php part.
now you put a script src in your html like

script src="js/ACE.php?class=myClass" (assuming myClass.class.php is in 
the same folder as ACE.php)

after that everything else is done automatically - ACE has created a new 
object called "myClass" in js which holds all methods of your php class 
- another side
effect is the included JSL library which enables full JS 1.5 support for 
old browsers.

an interaction is done like this:

var myClassObj = new myClass();
myClassObj.myMethod.call(some data, can be an array or an object - 
doesnt matter,foo1,foo2);
myClassObj.myMethod.result = function (d) { alert(d) }

thats it.

So the great thing is that you don´t have to customize the class for it 
(except the method table for security) and you get full JS 1.5 support 
for older browsers just out of the box. also you get an Object 
containing all your class methods so you can make Ajax transactions even 
with one-liners. The dynamic JS creation keeps the js download to a 
mininum. Last but not least the native support of php serialize in JS - 
thats why you can move all types of data around like it was all PHP. Ah 
- and its very fast, supports gzip compression etc...

Xajax seems a bit more complex to handle - never worked with it though ;)
