			A100213: Implementing Multi-dimensional Arrays in JavaScript. Unlike VBScript, JavaScript does not natively support multi-dimensional arrays. However, it is possible to simulate a multi-dimensional array by creating an array of arrays. This brief article demonstrates the technique. The following code snippet creates a "2-dimensional" array and populates it with two "rows" and three "columns" of data: JavaScript code: <script type="text/javascript"> // Create the array var Room = new Array(); Room[0] = new Array(); Room[1] = new Array(); // Populate the array Room[0][0] = "white"; Room[0][1] = "red"; Room[0][2] = "blue"; Room[1][0] = "black"; Room[1][1] = "yellow"; Room[1][2] = "purple"; // Iterate the array for (var i=0; i<2; i++) for (var j=0; j<3; j++) document.write(Room[i][j] + "<br>") </script> Browser output: white red blue black yellow purple This concept is easily extended to simulate three- and higher- dimensional arrays.
