I have trouble with the following code (I don't know how to describe it) :


Code:


function getData_result (result) {
_root.tempData = result ;
}
function load () {
trace (_root.tempData) ;
}
function init () {
myService.getData () ;
load () ;
}
init () ;
stop();




I'm trying to process the _root.tempData which is a reference to the result returned from service call GetData. tempData is assigned the result value from the service call but I can't access the tempData in the load function. But I can access it if the init function finish executing. Is there a way to access that variable from the same function call?

You can't access until its populated. Which means after the result handler fires. This would fix it.


function getData_result (result) {
_root.tempData = result ;
load () ;
}
function load () {
trace (_root.tempData) ;
}
function init () {
myService.getData () ;
}
init () ;
stop();

I see. but I may not want to use load () in the getData_result function every time. Just inside of the init function. Would a setInterval work?

I am not going to try and figure out why you don't want to use load() in the result handler. But a watch would work.


function getData_result (result) {
_root.tempData = result ;
}
load = function (prop, oldVal, newVal) {
trace (newVal);
};
function init () {
_root.watch("tempData", load);
myService.getData () ;

}
init () ;
stop();

nope didn't work :(. is there another function I can use?

I can access the tempData after init function has been called. but not inside the same function

[freddycodes]

I mean it does work, I don't just spew non-working code here for the fun of it, could you post your attempt? Even better to show you it works.


function getData_result (result) {
_root.tempData = result ;
}
load = function (prop, oldVal, newVal) {
trace (newVal);
};
function init () {
_root.watch("tempData", load);
getData_result ("Hello") ;
}
init () ;
stop();

Like I said before you can't access it until its populated, flash is not going to wait for the result handler to fire before moving to the next line of actionscript. So by trying to access tempData on the line below the service call, just is not going to work.

I apologize; I didn't read your code thoroughly. The code I placed above is a simplified version of the code below. The code involves two service calls, a getUTCID to populate a combobox, and loadData which loads saved data from a database and replaces the top item of combobox with the load item. That's the reason for running both functions inside of Init.



function init () {
service.getUTCID () ; //populates a combo box with data
_root.watch ("_root.utcidlist", service2.loadData (username,unit)) ;

}

function loadData_result (result) {
populate (holder, result,_root.utcidlist) //holder contains the combobox
//push the loaded item to the top of combobox

}

function getUTCID_result () {
.... some code
_root.utcidlist = result ;
}

init() ;
stop();


I know it's not pretty. I hope you can help. Thanks

Would you not be able to use


function init () {
service.getUTCID () ; //populates a combo box with data
}

function loadData_result (result) {
populate (holder, result,_root.utcidlist) //holder contains the combobox
//push the loaded item to the top of combobox

}

function getUTCID_result () {
// .... some code
_root.utcidlist = result ;
service.loadData (username,unit);
}

init() ;
stop();

Thanks that works. I don't know where my head is today.
