you would have to use a fadeIn function that i have not posted yet, if you get creative with the fade function, you can convert it into a working fadeIn function

HEllo ALL, I am new to forum but have used for almost 7 months.
I have an issue I think may be easy for some but for me it has given a bit of a head ache.

I would like too: have a user select multiple radio buttons and depending on what they select have them gotoAndStop at a certain frame.
I used a case switch to do this which works, but I am not able allow the user to select more or less than a given number
CODE:

var arr:Array = [];



////////////radiobuttons///////////////////

var rbL:Object = {};

rbL.click = function(obj:Object){

var sel = obj.target;

var dat = sel.data;

trace(sel+" - data - "+dat);

arr.push(dat);

};



for(var n:Number=1; n!=6; n++){

var init:Object = {_x:50, _y:n*40+280, label:n, data:n, groupName:"rb"+n};

var ref:MovieClip = this.attachMovie("RadioButton", "RB_"+n, n+1000, init);

ref.addEventListener("click", rbL);

}

////////////submit button///////////////////

this.attachMovie("Button","btnSubmit",2000,{_x:75, _y:675, label:"Design Studio"});



var Submit:Object = {};

Submit.click = function(){

var str:String = "";

for(var m:Number=0; m!=5; m++){ // take first 3 entries only

str += arr[m];

}

switch(str){

case "12345":

_root.gotoAndStop("vocal1");

break;

case "23451" :

_root.gotoAndStop("vocal2");

break;

case "231" :

_root.gotoAndPlay("studio1");

break;

case "213" :

_root.gotoAndPlay("studio1");

break;

case "312" :

_root.gotoAndPlay("studio1");

break;

case "321" :

_root.gotoAndPlay("studio1");

break;

case "4321" :

_root.gotoAndPlay("studio2");

break;

// and so on to cover all variations

case "678" :

trace("you selected 678");

break;

}

};



btnSubmit.addEventListener("click", Submit);



////////////reset button///////////////////

this.attachMovie("Button","btnReset",2100,{_x:75, _y:730, label:"Reset"});



var Reset:Object = {};

Reset.click = function(){

for(var n:Number=1; n!=5; n++){

_root["RB_"+n].selected = false;

}

arr = [];

};

btnReset.addEventListener("click", Reset);

ActionScript Code:

function numParity(num:Number):String {
    num % 2 ? parity = "odd" : parity = "even";
    return parity;
}

Description: A function that returns the parity of a number. In mathematics, parity refers to whether a number is odd or even.

Parameters:
num:Number - The number to analyze.

Returns:
String - If the number is found odd, "odd" will be returned, otherwise, if the number is found even, "even" will be returned.

Example Usage:
ActionScript Code:

function numParity(num:Number):String {
    num % 2 ? parity = "odd" : parity = "even";
    return parity;
}
trace(numParity(89)); // outputs odd
trace(numParity(9000)); // outputs even

How to do it in AS3 ?

How to do it in AS3 ?

this is already in AS3

function numParity(num:Number):String {
return num % 2 ? "odd" : "even";
}

[jbailey]

this is already in AS3
ActionScript Code:

function numParity(num:Number):String {
return num % 2 ? "odd" : "even";
}

WOW ... weird all last night I couldn't get it to work . Now it does in AS3 my bad and embarrassment - should have done more testing and with more sleep.

Hey everyone - a stupid little snippet, and one I'm sure everyone's come across, but I was looking a while back for a fast way to get the sign of a value, and eventually scratched this down:

function sign(val:Number):int
{
     return (val < 0) ? -1:1;
}

How simple does that get, eh? lol, but it's actually helped me out a lot.. Hope I'm passing along something as useful to someone else

verifyEmail function

verifyEmail(address:String) : Object
Reads the address parameter to a string and checks that it is compliant to the typical "valid" email standards of today.

Parameters

address:String - The email that you want to be validated. The function does not directly modify any variables.

Returns

Object- An Object value, whether or not the email is valid. If the email is invalid it will return the error, otherwise it will return true, or valid.

Example

The following demonstrates the usage of the validator over every condition, displaying every possible result. ActionScript Code:

function verifyEmail(address:String):Object {
if (address.indexOf("@") == -1) {
return "Error: Invalid Address - No domain name entered.";
} else if (address.indexOf(".") == -1) {
return "Error: Invalid Address - No top-level domain entered.";
} else if (address.indexOf("@")<5) {
return "Error: Invalid Address - Address too short.";
} else if (address.lastIndexOf(".")-5<=address.lastIndexOf("@")) {
return "Error: Invalid Address - Domain name too short.";
} else if (address.charAt(0) == "." || address.charAt(0) == "_" || address.charAt(0) == "-") {
return "Error: Invalid Address - Address invalid.";
} else if (address.split("@").length != 2) {
return "Error: Invalid Address - Too many @s.";
} else if (address.indexOf(" ") != -1 || address.indexOf("<") != -1 || address.indexOf(">") != -1 || address.indexOf("(") != -1 || address.indexOf(")") != -1 || address.indexOf("[") != -1 || address.indexOf("]") != -1 || address.indexOf("\\") != -1 || address.indexOf(",") != -1 || address.indexOf(";") != -1 || address.indexOf(":") != -1) {
return "Error: Invalid Address - Invalid characters.";
}
return true;
}
trace(verifyEmail("test"));
// Outputs Error: Invalid Address - No domain name entered. (There needs to be at least one @)
trace(verifyEmail("tester@test"));
// Outputs Error: Invalid Address - No top-level domain entered. (There needs to be at least one .)
trace(verifyEmail("<a href="mailto:test@test.com">test@test.com</a>"));
// Outputs Error: Invalid Address - Address too short. ("test" is not long enough to be a valid address)
trace(verifyEmail("<a href="mailto:tester@test.com">tester@test.com</a>"));
// Outputs Error: Invalid Address - Domain name too short. ("test" is not long enough to be a valid domain name)
trace(verifyEmail("<a href="mailto:_tester@tester.com">_tester@tester.com</a>"));
// Outputs Error: Invalid Address - Address invalid. (Addresses cannot start with .)
trace(verifyEmail("<a href="mailto:-tester@tester.com">-tester@tester.com</a>"));
// Outputs Error: Invalid Address - Address invalid. (Addresses cannot start with -)
trace(verifyEmail("<a href="mailto:.tester@tester.com">.tester@tester.com</a>"));
// Outputs Error: Invalid Address - Address invalid. (Addresses cannot start with _)
trace(verifyEmail("<a href="mailto:tester@@tester.com">tester@@tester.com</a>"));
// Outputs Error: Invalid Address - Too many @s. (Addresses can contain only one @ symbol)
trace(verifyEmail("test <a href="mailto:er@tester.com">er@tester.com</a>"));
// Outputs Error: Invalid Address - Invalid characters.(Addresses cannot contain a space)
trace(verifyEmail("test:er@tester.com"));
// Outputs Error: Invalid Address - Invalid characters.(Addresses cannot contain a
trace(verifyEmail("test;er@tester.com"));
// Outputs Error: Invalid Address - Invalid characters.(Addresses cannot contain a
trace(verifyEmail("test>er@tester.com"));
// Outputs Error: Invalid Address - Invalid characters.(Addresses cannot contain a >)
trace(verifyEmail("test<<a href="mailto:er@tester.com">er@tester.com</a>"));
// Outputs Error: Invalid Address - Invalid characters.(Addresses cannot contain a <)
trace(verifyEmail("test\er@tester.com"));
// Outputs Error: Invalid Address - Invalid characters.(Addresses cannot contain a \)
trace(verifyEmail("test,er@tester.com"));
// Outputs Error: Invalid Address - Invalid characters.(Addresses cannot contain a ,)
trace(verifyEmail("test[er@tester.com"));
// Outputs Error: Invalid Address - Invalid characters.(Addresses cannot contain a [)
trace(verifyEmail("test]er@tester.com"));
// Outputs Error: Invalid Address - Invalid characters.(Addresses cannot contain a ])
trace(verifyEmail("test(<a href="mailto:er@tester.com">er@tester.com</a>"));
// Outputs Error: Invalid Address - Invalid characters.(Addresses cannot contain a ()
trace(verifyEmail("test)er@tester.com"));
// Outputs Error: Invalid Address - Invalid characters.(Addresses cannot contain a ))
trace(verifyEmail("<a href="mailto:tester@tester.com">tester@tester.com</a>"));
// Outputs true, the email is valid

I tested this code exactly and it was working as described. i had to take alot of the double quotes to single quotes so it would begin to work correctly but then it wouldn't respond correctly tot he right email address. anyway just an FYI....

How about regular expressions?

var email_pattern: RegExp =/^\w+([\-\w]+)*\w@\w+(([\.\-]\w)*\w+)*\.\w{2,4}$/i

[LordMoyne]

ActionScript Code:

function factorial(num:Number):Number {
var nShriek:Number = num;
if (num > 0) {
while (num > 1) {
num--;
nShriek *= num;
}
return nShriek;
} else if (!num) {
return 1;
}
}

Description: A function that returns n! (factorial) from a positive integer or the amount of combinations possible from a set. nShriek is an informal way of saying nFactorial.

Parameters:
num:Number - The number to analyze.

Returns:
Number - n! or the amount of combinations possible.

Example Usage:
ActionScript Code:

var setA:String = "cat";
var setB:String = "apple";
trace(factorial(setA.length + "combinations")); // outputs 6 combinations
trace(factorial(setB.length + "combinations")); // outputs 120 combinations

trace(factorial(0)); // outputs 1
trace(factorial(1000)); // outputs Infinity
trace(factorial(4); // outputs 24

Wow, is this a joke? Besides the clumsy nature in which its written, it will break if you pass it a negative number, and will also exhibit odd and incorrect behavior if given a non-whole number (you did type it as a Number after all for a function that only accepts natural numbers). Try this:

function factorial(num:int):int {
    if (num < 1 || !num) return 0;
    var fact:int = 1;
    for (var i:int = 2; i <= num; i++) fact *= i;
    return fact;
}

Well that was AS2.

[LordMoyne]

function verifyEmail(address:String):Object {
 if (address.indexOf("@") == -1) {
  return "Error: Invalid Address - No domain name entered.";
 } else if (address.indexOf(".") == -1) {
  return "Error: Invalid Address - No top-level domain entered.";
 } else if (address.indexOf("@")<5) {
  return "Error: Invalid Address - Address too short.";
 } else if (address.lastIndexOf(".")-5<=address.lastIndexOf("@")) {
  return "Error: Invalid Address - Domain name too short.";
 } else if (address.charAt(0) == "." || address.charAt(0) == "_" || address.charAt(0) == "-") {
  return "Error: Invalid Address - Address invalid.";
 } else if (address.split("@").length != 2) {
  return "Error: Invalid Address - Too many @s.";
 } else if (address.indexOf(" ") != -1 || address.indexOf("<") != -1 || address.indexOf(">") != -1 || address.indexOf("(") != -1 || address.indexOf(")") != -1 || address.indexOf("[") != -1 || address.indexOf("]") != -1 || address.indexOf("\\") != -1 || address.indexOf(",") != -1 || address.indexOf(";") != -1 || address.indexOf(":") != -1) {
  return "Error: Invalid Address - Invalid characters.";
 }
 return true;
}

OH GOD, MY EYES! That is so, SO bad. And broken, too.

Try this for size. This will work with any email you throw at it, and follows all the web standards for a proper email address (unlike the above):

//returns true is the email address is valid, false if not.
function validateEmail(email:String):Boolean {
    var regexp:RegExp = /^\w[\w_\.\-\+]*?@\w([\w_\-\+]*?\.)+?[a-zA-Z]+$/;
    return !(regexp.exec(email) == null);
}

[TheCanadian]

Again, AS2.

There are numerous problems with that. It doesn't accept . _ and +, which are valid in all but the domain. It also allows numerals in the domain, which is invalid. It also requires the domain to be between 2 and 4 characters, which is not required.

Random Color
This function will return a random color as a unit value.
ActionScript Code:

function randomColor():uint {
&nbsp;&nbsp;&nbsp;&nbsp;var colorArray:Array = new Array("0x");
&nbsp;&nbsp;&nbsp;&nbsp;for (var i:Number = 1; i<=3; i++) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;co lorArray[i] = Math.floor(Math.random() * (255 - 0 + 1)) + 0;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;co lorArray[i] = colorArray[i].toString(16);
&nbsp;&nbsp;&nbsp;&nbsp;}
&nbsp;&nbsp;&nbsp;&nbsp;var unitNum:uint = new uint(colorArray.join(""));
&nbsp;&nbsp;&nbsp;&nbsp;return unitNum;
}

Example
This will draw a box 200 pixels wide by 200 pixels tall and fill it with a random color.
ActionScript Code:

function randomColor():uint {
var colorArray:Array = new Array("0x");
for (var i:Number = 1; i<=3; i++) {
colorArray[i] = Math.floor(Math.random() * (255 - 0 + 1)) + 0;
colorArray[i] = colorArray[i].toString(16);
}
var unitNum:uint = new uint(colorArray.join(""));
return unitNum;
}
import flash.display.Graphics;
import flash.display.Sprite;
var box:Sprite = new Sprite();
box.graphics.beginFill(randomColor());
box.graphics.drawRect(0,0,200,200);
box.graphics.endFill();
addChild(box);

Man, these things just get worse and worse. I'm not even going to ask what the deal is with that (255 - 0 + 1).

function getRand():uint {
    return ((Math.floor(Math.random() * 256)<<16) + (Math.floor(Math.random() * 256)<<8) + Math.floor(Math.random() * 256));
}

For comparisons sake, 1,000,000 iterations of my code ran in 750ms. 1 million of yours took nearly 10 seconds.
