Sort two dimensional arrays using Javascript

This nifty little routine is very useful. With it, one can sort tables on a web page without having to reload the entire page. To see an example in action click here.

Here is the contents of the file I call "2darraysort.js" which contains the sort2DArray() function that does all the work:
// ** Does Simple Bubble Sort of 2 Dimensional Array // ------------------------------------------------------ // Function Parameters: // ------------------------------------------------------ // sortArray = variable for 2 dimensional array to sort // sortCol = column number to sort on. // totCols = total columns in array. // totRows = total rows in array. // sortOrder = Duh! the sort order! "asc" = ascending "desc" = descending order // optionBase = starting element number in array (normally zero) // (c) copyright 2007, Orville Paul Chomer, Chomer.com // This is freeware. Just include copyright notice in any source code used. // Enjoy! function sort2DArray(sortArray, sortCol, totCols, totRows, sortOrder, optionBase) { var bKeepWorking = true; var nPass = 0; while (bKeepWorking == true) { nPass++; var bFound = false; for (a=optionBase;a<totRows-1+optionBase;a++) { if ( ((sortArray[a][sortCol] > sortArray[a+1][sortCol]) && (sortOrder != "desc")) || ((sortArray[a][sortCol] < sortArray[a+1][sortCol]) && (sortOrder == "desc")) ) { var swap = new Array(); for (c=optionBase;c<=totCols-1+optionBase;c++) { swap[c] = sortArray[a+1][c]; sortArray[a+1][c] = sortArray[a][c]; sortArray[a][c] = swap[c]; } // next c bFound = true; } // end if } // next a bKeepWorking = bFound; } // end while (bKeepWorking == true) return sortArray; } // end of function 2DArraySort()
