Client-side table sorting for flexigrid

Writer:?

I wrote a function to perform sorting of the table locally instead of?
making a trip to the server each time. It uses the ".sorted" class to?
determine which column needs sorting,thus only the table selector is?
passed along with the sort order. At this stage it supports alphabetic?
and (slightly crude) numeric sorting. I hope this helps someone.?
Suggestions welcome.?

Here is the function:?

?

function sortGrid(table,order) { var stripChar = function(s,c) { var r = ""; for(var i = 0; i < s.length; i++) { r += c.indexOf(s.charAt(i))>=0 ? "" : s.charAt(i); } return r; } // Test for characters accepted in numeric values. var isNumeric = function(s) { var valid = "0123456789.,- "; var result = true; var c; for(var i = 0; i < s.length && result; i++) { c= s.charAt(i); if(valid.indexOf(c) <= -1) { result = false; } } return result; } // Sort table rows. var asc = order == "asc"; var rows = $(table).find("tbody > tr").get(); var column = $(table).parent(".bDiv").siblings(".hDiv").find("table tr th").index($("th.sorted",".flexigrid:has(" + table + ")")); rows.sort(function(a,b) { var keyA = $(asc? a : b).children("td").eq(column).text().toUpperCase(); var keyB = $(asc? b : a).children("td").eq(column).text().toUpperCase(); if((isNumeric(keyA)||keyA.length<1) && (isNumeric(keyB)|| keyB.length<1)) { keyA = stripChar(keyA,","); keyB = stripChar(keyB,"); if(keyA.length < 1) keyA = 0; if(keyB.length < 1) keyB = 0; keyA = new Number(parseFloat(keyA)); keyB = new Number(parseFloat(keyB)); } return keyA>keyB ? 1 : keyA<keyB ? -1 : 0; }); // Rebuild the table body. $.each(rows,function(index,row) { $(table).children("tbody").append(row); }); // Fix styles $(table).find("tr").removeClass("erow"); // Clear the striping. $(table).find("tr:odd").addClass("erow"); // Add striping to odd numbered rows. $(table).find("td.sorted").removeClass("sorted"); // Clear sorted class from table cells. $(table).find("tr").each(function() { $(this).find("td:nth(" + column + ")").addClass("sorted"); // Add sorted class to sorted column cells. }); }?

Use it via:

$("#table").flexigrid({ ... onChangeSort: function(name,order) { sortGrid("#table",order); } ... });?
