Sorting an array of numbers
The standard method of sorting in flash with myArray.sort
uses a string comparison. If you sort an array of numbers, 
all numbers starting with 0 come first, then 1 and so on. 
If you want numerical ordering, like 10 comes after 9 you 
have to provide your own function to compare two values of 
your array. Here is the example to sort numerical: 

// Defining the function which does the comparison in the sort function
// The function takes two parameters a and b and returns -1 if a < b, 
// 0 if a = b and 1 if a > b. 
function compareNumbers( a, b){
    return((a > b) - (a < b))
}

// make a new array for our test
myArray = new Array();

// fill the array with random numbers
for(i=0;i<20;i++){
	myArray[i] = random(20);
}

// how does it look like unsorted ?
trace("unsorted: " add myArray);

// sort it with standard sort function
myArray.sort();

// how does it look now ?
trace("stringsorted: " add myArray);

// sort it with our numerical comparison
myArray.sort(compareNumbers);

// yes - thats what we were looking for :)
trace("numbersorted: " add myArray);

You could also use an simple Bubblesort:

function bubbleSort(inputArray, start, rest) {
   for (var i = rest - 1; i >= start;  i--) {
      for (var j = start; j <= i; j++) {
         if (inputArray[j+1] < inputArray[j]) {
            var tempValue = inputArray[j];
            inputArray[j] = inputArray[j+1];
            inputArray[j+1] = tempValue;
         }
      }
   }

Hi,

Sorting an array of numbers works fine on its own. I m trying to capture 7 different into array. The same gets well into array; also works stupidly (string sort) till step 2 as it should.

But shows the same output even for the last step; which hopefully should be number sorted. Have u ever come across the same. Is there any email ID, where I can send the FLA just for ref.

Thankz & Regards,
Mahesh

Didn't work for me!


I modified the code to this;

function compareNumbers(a, b) {
	return (Boolean((a-b)>0));
}

and it works fine!
