ActionScript 3 help ! : )

Expand Post »

Hola, Im an experienced coder, however new to java/actionscript 3

I am trying to make a very simple login and I am running into problems. They seem to be with my for loop with the .Length() function in particular...

Graphics and Multimedia Syntax (Toggle Plain Text)
stop();
loginError.visible = false;
var loginXml:XML;
var loader:URLLoader = new URLLoader(); 
loader.load(new URLRequest("logindata.xml"));
loader.addEventListener(Event.COMPLETE, loadXML);
var loginData = new Array();
var temp:Array = new Array();
function loadXML(e:Event):void
{
    loginXml = new XML(e.target.data);
	var total = loginXml.item.length();
	var x:int = 0;
	for(x=0; x < total; x++)
	{
		loginData[x] = new Array();
		loginData[x][0] = loginXml.item[x].user.toString();
		loginData[x][1] = loginXml.item[x].pass.toString();
	}
 
}
loginBtn.addEventListener(MouseEvent.CLICK, loginFunction2);
 
function loginFunction2(e:MouseEvent):void
{
	var success:Boolean = false;
    //SEEMS TO BE WHERE MY ERROR STARTS
    var lengthLD:int = loginData.length();
	for(var i=0; i < lengthLD; i++)                   //Most Likley the Error
	{
		if(user.text == loginData[i][0] && pass.text == loginData[i][1])
		  {
			  success = true;
			  gotoAndStop(user.text);
		  }
	}
	if(!success)
	{
		loginError.visible = true;
	}
}
stop();
loginError.visible = false;
var loginXml:XML;
var loader:URLLoader = new URLLoader(); 
loader.load(new URLRequest("logindata.xml"));
loader.addEventListener(Event.COMPLETE, loadXML);
var loginData = new Array();
var temp:Array = new Array();
function loadXML(e:Event):void
{
    loginXml = new XML(e.target.data);
	var total = loginXml.item.length();
	var x:int = 0;
	for(x=0; x < total; x++)
	{
		loginData[x] = new Array();
		loginData[x][0] = loginXml.item[x].user.toString();
		loginData[x][1] = loginXml.item[x].pass.toString();
	}
	
}
loginBtn.addEventListener(MouseEvent.CLICK, loginFunction2);

function loginFunction2(e:MouseEvent):void
{
	var success:Boolean = false;
    //SEEMS TO BE WHERE MY ERROR STARTS
    var lengthLD:int = loginData.length();
	for(var i=0; i < lengthLD; i++)                   //Most Likley the Error
	{
		if(user.text == loginData[i][0] && pass.text == loginData[i][1])
		  {
			  success = true;
			  gotoAndStop(user.text);
		  }
	}
	if(!success)
	{
		loginError.visible = true;
	}
}

Any help would be great,
Thanks : )

Re: ActionScript 3 help ! : )

I'd just make a global variable

(Toggle Plain Text)

var loginXml:XML;
var loader:URLLoader = new URLLoader(); 
loader.load(new URLRequest("logindata.xml"));
loader.addEventListener(Event.COMPLETE, loadXML);
var loginData = new Array();
var temp:Array = new Array();


var gtotal:int = 0;

function loadXML(e:Event):void
{
    loginXml = new XML(e.target.data);
	gtotal = loginXml.item.length();	
                var x:int = 0;
	for(x=0; x < gtotal; x++)
	{
		loginData[x] = new Array();
		loginData[x][0] = loginXml.item[x].user.toString();
		loginData[x][1] = loginXml.item[x].pass.toString();
		
		//trace it out
		//trace(loginData[x][1]);
		
		
	}
	
	//trace(gtotal);
	
}

button1.addEventListener(MouseEvent.CLICK, go);
function go(e:MouseEvent)
{
  var success:Boolean = false;

   
	for(var i=0; i < gtotal; i++)                   //Most Likley the Error
	{
		if(user.text == loginData[i][0] && pass.text == loginData[i][1])
		  {
			  success = true;
			  //gotoAndStop(user.text);
		  }
	}
	if(!success)
	{
		//loginError.visible = true;
	}
	
	trace(success);

}

my xml file:

Graphics and Multimedia Syntax (Toggle Plain Text)

<root>
  <item>
    <user>john</user>
    <pass>password</pass>
  </item>
  <item>
    <user>sally</user>
    <pass>hello</pass>
  </item>
</root>

Re: ActionScript 3 help ! : )

In AS 3.0, its very simple to find the length.

Step 1:

Use this:

Graphics and Multimedia Syntax (Toggle Plain Text)
var loginform:XMLList;
var total:Number=0;
var loginform:XMLList;
var total:Number=0;

instead of :

Graphics and Multimedia Syntax (Toggle Plain Text)
var gtotal:int = 0;
var gtotal:int = 0;

Step 2:

use this:

Graphics and Multimedia Syntax (Toggle Plain Text)
total = loginform.length();
total = loginform.length();

instead of:

Graphics and Multimedia Syntax (Toggle Plain Text)
gtotal = loginXml.item.length();
gtotal = loginXml.item.length();

Sure It will work, if yes, mark as solved. Thanks

Re: ActionScript 3 help ! : )

I looked into your code and executed the half, but your method of total is perfectly working.

Mr. DevC++4.9.9.2,

I am so sorry I am confused forget all those things said above, that is also correct, but in your program nothing is wrong except you have to remove two parenthesis in length function, thats it done.

var lengthLD:int = loginData.length;

Yep post #5 was the correct answer, or should I say the shortest answer/fix.

Re: ActionScript 3 help ! : )

Thank you very much... This answer worked... I am coming from c++ and these little things are ganna kill me lol

My final code:

Graphics and Multimedia Syntax (Toggle Plain Text)
stop();
loginError.visible = false;
var loginXml:XML;
var loader:URLLoader = new URLLoader(); 
loader.load(new URLRequest("logindata.xml"));
loader.addEventListener(Event.COMPLETE, loadXML);
var loginUser:Array = new Array();
var loginPass:Array = new Array();
var total:Number = 0;
function loadXML(e:Event):void
{
    loginXml = new XML(e.target.data);
	total = loginXml.length();
	var x:Number = 0;
	for(x=0; x < total; x++)
	{
		loginUser.push(loginXml.item[x].user.toString());
		loginPass.push(loginXml.item[x].pass.toString());
	}
}
loginBtn.addEventListener(MouseEvent.CLICK, loginFunction);
 
function loginFunction(e:MouseEvent):void
{
	var success:Boolean = false;
	var i:Number = 0;
	for(i=0; i < total; i++)
	{
		if(user.text == loginUser[i] && pass.text == loginPass[i])
		  {
			  success = true;
			  gotoAndStop(user.text);
		  }
	}
	if(!success)
	{
		loginError.visible = true;
	}
}
stop();
loginError.visible = false;
var loginXml:XML;
var loader:URLLoader = new URLLoader(); 
loader.load(new URLRequest("logindata.xml"));
loader.addEventListener(Event.COMPLETE, loadXML);
var loginUser:Array = new Array();
var loginPass:Array = new Array();
var total:Number = 0;
function loadXML(e:Event):void
{
    loginXml = new XML(e.target.data);
	total = loginXml.length();
	var x:Number = 0;
	for(x=0; x < total; x++)
	{
		loginUser.push(loginXml.item[x].user.toString());
		loginPass.push(loginXml.item[x].pass.toString());
	}
}
loginBtn.addEventListener(MouseEvent.CLICK, loginFunction);

function loginFunction(e:MouseEvent):void
{
	var success:Boolean = false;
	var i:Number = 0;
	for(i=0; i < total; i++)
	{
		if(user.text == loginUser[i] && pass.text == loginPass[i])
		  {
			  success = true;
			  gotoAndStop(user.text);
		  }
	}
	if(!success)
	{
		loginError.visible = true;
	}
}

thanks again
