How to exit a function in the middle and continue on with the code

how to come out of a function in between and continue the code

I saw a lot of searches for this so I decided to write an article about it. So you can jump out of a function at anytime using the "return;" command. Here is an example

function test(isContinue):void{

var i:String = "bal bla ablababallaa";

trace(i);

if (!isContinue){

return;

}

i = i+"sadfdsafasdfasdf";

trace(i);

}

test(false);

This bit of code will output:

bal bla ablababallaa

if we run

test(true)

then we end up with :

bal bla ablababallaasadfdsafasdfasdf

you can use "return;" on functions that return a value or that do not have a return type or are of return type void as I have shown above.

Another interesting technique that is simular to this is getting out of a loop but not out of the function. Lets take our original function and modify it to show how "break;" works.

function test(isQuitEarlyOn5):void{

var i:uint;

for(i; i < 10; i++){

if (i == 5 && isQuitEarlyOn5){

break;

}

trace(i);

}

trace("done");

}

// if we run the function

test(true);
