Generate an array of Unique random numbers from 1 to n

numberOfElements = 50;
myNumbers = new Array(numberOfElements);
randomNumbers = new Array(numberOfElements);

for(i=0;i<%lt%>numberOfElements;i++){
    myNumbers[i] = i+1;
}
i=0;
while(myNumbers.length <%gt%> 0){
    thePosition = Math.round(Math.random()*(myNumbers.length-1))
    randomNumbers[i] = myNumbers[thePosition];
    i++;
    myNumbers.splice(thePosition,1);
}
for(i=0;i<%lt%>numberOfElements;i++){
    trace(randomNumbers[i]);
}
