Contains is an actionscript function that I use a lot. From Kirupa

contains = function (input, arrayData) {
  for (i=0; i<arrayData.length; i++) {
    if (arrayData[i] == input) {
      return 1;
    }
  }
  return -1;
};

A simple version of the explode() function in PHP. It takes a string and splits it up into an array by splitting it at whatever character (or characters) you specify. For example, reading in a tab delimited text file. Will split it into lines by splitting on returns ("\r"). Then split up the lines by splitting on tabs ("\t").

Attribution: I didn't write this myself, I found it in a comment on one of the Actionscript on-line documentation pages.

function explode(separator:String, string:String) {

        var list = new Array();

        if (separator == null) return false;
        if (string == null) return false;

        var currentStringPosition = 0;
        while (currentStringPosition<string.length) {
                var nextIndex = string.indexOf(separator, currentStringPosition);
                if (nextIndex == -1) break;
                var word = string.slice(currentStringPosition, nextIndex);
                list.push(word);
                currentStringPosition = nextIndex+1;
        }
        if (list.length<1) {
                list.push(string);
        } else {
                list.push(string.slice(currentStringPosition, string.length));
        }
        return list;
}

Here's a cheap little function to mimic the print_r() function from PHP in Actionscript. It's designed to work on most any array and will handle nested arrays through recursion.

//
// recursive function to print out the contents of an array similar to the PHP print_r() funciton
//
function print_a( obj, indent ) {
        if (indent == null) indent = "";
        var out = "";
        for ( item in obj ) {
                if (typeof( obj[item] ) == "object" )
                        out += indent+"[" + item + "] => Object\n";
                else
                        out += indent+"[" + item + "] => " + obj[item]+"\n";
                out += print_a( obj[item], indent+"   " );
        }
        return out;
}
// example call
trace( print_a( example_array ) );

This function will strip out all tabs and return characters. It will also collapse all runs of multiple spaces down to one. It will also remove a leading and trailing spaces. It is similar to the php_strip_whiespace() function in PHP.

function collapseWhiteSpace( theString ) {
        theString =  theString.split("\r").join("");
        theString =  theString.split("\t").join("");
        while ( theString.indexOf("  " ) != -1 ) {
                theString= theString.split("  ").join(" ");
        }
        if (theString.substr(0,1) == " ") {
                theString = theString.substr( 1 );
        }
        if (theString.substr( theString.length-1, 1 ) == " ") {
                theString = theString.substr( 0, theString.length - 1 );
        }
        return( theString );
}

Random number function - returns a number between min and max
Receives (min, max)
Returns randomNum

function randRange(min:Number, max:Number):Number {
    var randomNum:Number = Math.floor(Math.random() * (max - min + 1)) + min;
    return randomNum;
}

// Countdown code

countDown = function() {
        seconds_conta = seconds_conta - 1;
        hours = int(seconds_conta / 3600);
        minutes = int((seconds_conta / 60) - (hours * 60));
        //seconds = int(seconds_conta-((hours*3600)+minutes*60));
        seconds = int((seconds_conta % 60));
        
        //Se for menor que dez, acrescenta um zero
        if(minutes<10){
                minutes="0"+minutes;
        }
        if(seconds<10){
                seconds="0"+seconds;
        }
        
        //Será que precisa colocar no frame correto?
        timer_txt.text=(hours+":"+minutes+":"+seconds);
        
                //trace("seconds_conta: "+seconds_conta);
                //trace("hours: "+hours);
                //trace("minutes: "+minutes);
                //trace("seconds: "+seconds);
        
        if (seconds_conta == 0) {
          clearInterval(timer);
                  //Chama função de acabar a contagem!
                  //fim_das_questões();
     }
} 

///////// Acrescentar no código
//Tempo total inicial em segundos ->Calculado a partir da quantidade de questões
seconds_conta = 185;
///////// Inicia o timer
//A cada 1000 ms, ativa a função countDown, diminuindo um segundo do total
timer = setInterval(countDown, 1000);

function isConnected():Boolean {
var results = mdm.Network.checkConnection();

Ideally, at some point, I'll modify the plug-in for EE that shows Flash objects to use flashobject.js.

This code assumes custom fields in the blog.

{if project_video_title}<h4>{project_video_title}: Video Clip</h4>{/if}

function testMe() {
 trace("callback: "+getTimer()+" ms.");
}

var intervalID:Number = setTimeout(testMe, 1000);

// clearTimeout(intervalID) // for clear the timeout

It's simple, yet I often forget this.

var myMC:MovieClip;
var i = 1;
var pad = 5;
while (i<6) {
        trace(" i : "+i);
        myMC.duplicateMovieClip("myMC"+i, i);
        myMC.removeMovieClip();
        this["myMC"+i]._x = this["myMC"+(i-1)]._x+(this["myMC"+(i-1)]._width)+pad;
        this["myMC"+i].onRollOver = function() {
                trace(this);
        };
        i++;
}

Use the LocalConnection object to get the domain name of the server where the Flash movie is located.

var localDomainLC:LocalConneciton = new LocalConnection();
myDomainName = localDomainLC.domain();
trace( "My domain is " + myDomainName );

This will print out something like this:

My domain is example.com

I'm always forgetting the syntax for this...

var oImgListener = new Object();
oImgListener.onLoadInit = function(target_mc)
{
     trace(target_mc._name + "  load complete");
     ...
}

var mclImg = new MovieClipLoader();
mclImg.addListener(oImgListener);
mclImg.loadClip("http://myurl.com/path/to/swf/or/jpg", mcImgLoader);
