Unique random # func - Flash

• guiles

  I'm trying to figure out how to generate a unique number and display content from an array.

  I've got it set up to when you click a button it runs the askAgain(); function (see code below) and displays the result in a dynamic text field.
  --
  quesArray = new Array();
  quesArray[1] = "1";
  quesArray[2] = "2";
  quesArray[3] = "3";
  quesArray[4] = "4";
  quesArray[5] = "5";
  quesArray[6] = "6";
  quesArray[7] = "7";
  quesArray[8] = "8";
  quesArray[9] = "9";
  quesArray[10] = "10";
  quesArray[11] = "11";
  askAgain = function () {
  q = random(11)+1;
  question = quesArray[q];
  };
  askAgain();
  --
  Now when I click the button, sometimes it generates the SAME result. I want it to be a unique result everytime. Ihope this makes sense, thanks for your help.

  If you want to see my example go here: http://www.osu-okmulgee.edu/acad…

  Once everything loads click on the "?" button above the character on the left.... that is what I'm doing.

  Here's an Array prototype that will return a random index from the array (and delete that index):

  Array.prototype.spitRandom = function() {
  var i =random(this.length)
  var spit = this[i];
  this.splice(i,1);
  return(spit);
  }

  In your example, you can then use

  var answer = quesArray.spitRandom();

  to give you a random value.

  Cheers.
