I'd like to create a multi-dimensional array to hold mc names and labels but so far I haven't found the correct syntax.

This is what I'd expect the format to be,...
_root.DirectorArray = new Array();

_root.DirectorArray[1][1] = "dir_1"; // mc name //
_root.DirectorArray[1][2] = "D_1"; // mc timeline label //

but it and several other attempts have failed.

Thanks, DC

If you have a short multi dimensional array, you could simply type it out...like this (indented for clarity)

_root.DirectorArray =
   [
      ["dir_1", "D_1"],
      ["dir_2", "D_2"],
      ["dir_3", "D_3"],
      ["dir_4", "D_4"]
   ];

now

      _root.DirectorArray[2][0];




would return

      "dir_3"




But if the content of your array is fairly large and as structured as your example imply, you might safe some typing and perhaps gain some flexibility by using a series of anonymous objects in a "regular" array for ease of access?

      _root.DirectorArray = new Array ();





      var maxNum = 20; // number of objects in array





      for (i=0; i<maxNum; i++) {





      var temp = new Object();





      temp.mcName = "dir_" + i;





      temp.mcLabel = "D_" + i;





      _root.DirectorArray.push(temp)





      }




Now

      _root.DirectoryArray[3].mcName;




would return

      "dir_3"




and similar

      _root.DirectoryArray[3].mcLabel;




would return

      "D_3"




I haven't actually tested any of this, so no guarantees it will work exactly as typed here. Let me know if I messed it up somewhere.

Hope it helps...
