Simple and works fine.
var sDataArray = MultiDimensionalArray(2, 2); function MultiDimensionalArray(iRows, iCols) { var i; var j; var table = new Array(iRows); for (i = 0; i < iRows; i++) { table[i] = new Array(iCols); for (j = 0; j < iCols; j++) { table[i][j] = ""; } } return (table); }

It looks like this function won't work when initializing arrays with more than 2 dimensions.
var arr = []; for(var i = 0;i<100;++i){ arr[i] = []; for(var j = 0; j < 100; ++j){ arr[i][j] = i*j; } }

Its an array of arrays.
var arr = [ [0,1,2], [3,4,5], [ ['a','b','c'] ] ];
