Hi All is there any way to locally define a variable in a function and then pass it to the oher function. I mean to say is it possible the pass a local value from one function to other function. Somebody Please suggest me the solution. Thanks in advance

Or it's that simple or you meant something else:
private function function1():void
{
var localVariable:String = "this is local variable of function1()";
function2(localVariable);
}
private function function2(string:String):void
{
trace(string);
}
function1();
or use global variable as temporary storage:
private var globalVariable:String = "";
private function function1():void
{
var localVariable:String = "this is local variable of function1()";
globalVariable = localVariable;
}
private function function2():void
{
trace(globalVariable);
}
function1();
function2();

Hi zdmytriv, Yes thats what i was wanted as a solution..Thanks a ton.!!
zdmytriv is right.
Although, you can also make default variables, like so:
(Modifying zdmytriv's code)
private function function1():void
{
var localVariable:String = "this is local variable of function1()";
function2(localVariable);
function2(); //You don't have to enter a default argument
}
private function function2(string:String = "something else"):void
{
trace(string);
}
This would trace:
this is local variable of function1()
something else
A little off topic, but good to know.

Thanx pipeep for such a nic explanation.
Primitives in Flex are passed by value, where complex objects are passed by reference. You can use this to pass objects around without scoping a variable outside the functions themselves. For instance:
private function function1():void {
{
var localVar:Object = {value:"test"};
trace(localVar.value);
function2(localVar);
trace(localVar.value);
}
private function function2(obj:Object):void
{
obj.value = "new value";
}
This would trace:
test
new value
Which reflects the fact that function2 receives the parameter "obj" by reference, as a pointer to the original "localVar" object. When it sets the .value field, that change is reflected in function1.
I just thought I'd point that out.
