dojo - dgrid custom sort with secondary sort column -

-

i'm using custom sort function on dgrid (pasted below). doesn't change sorting drastically, sorts 1 particular column uniquely , sorts others case-insensitive. i'd add secondary sort column named "scheduled" added sort when other column sorted. i'm not sure how go it. i've seen how override sort sort 2 columns, not when custom sort in play. secondary sort there, not matter other column clicked.

for reference i'm running dojo 1.10 , dgrid 1.0. data coming requestmemory dstore , i'd rather sort happen on grid rather @ store level. appreciated.

currgrid.on('dgrid-sort', function (event) {    event.preventdefault();    var sort = event.sort[0];    currgrid.set('sort', function (a, b) {       if (sort.property == "thisfield") {         //special sort thisfield         if (a[sort.property] !== 'undefined' && typeof a[sort.property] == "string") {            var colora =  a[sort.property].split("|");            var avalue = colora[0].tolowercase();         }         if (b[sort.property] !== 'undefined' && typeof b[sort.property] == "string") {            var colorb =  b[sort.property].split("|");            var  bvalue = colorb[0].tolowercase();         }         if (string(avalue) == string(bvalue)) {            var result = 0;         } else if (dojo.string.trim(avalue) == "") {            var result = true ? 1 : -1;         } else if (dojo.string.trim(bvalue) == "") {           var result = true ? -1 : 1;         } else {           var result = avalue > bvalue ? 1 : -1;         }         return result * (sort.descending ? -1 : 1);       } else {         //sort other fields same (except tolowercase)         if (a[sort.property] !== 'undefined' && typeof a[sort.property] == "string") {            var avalue = a[sort.property].tolowercase();         } else {            var avalue = "";         }         if (b[sort.property] !== 'undefined' && typeof b[sort.property] == "string") {            var bvalue = b[sort.property].tolowercase();         } else {            var bvalue = "";         }         var result = avalue > bvalue ? 1 : -1;         return result * (sort.descending ? -1 : 1);       }    });    currgrid.updatesortarrow(event.sort, true);  });  currgrid.startup();

you below.

currgrid.on('dgrid-sort', function (event) {     event.preventdefault();     var sortset = [];     sortset.push(event.sort[0]);     sortset.push({property: "scheduled"});     currgrid.set('sort', function (a, b) {         var avalue, bvalue, result = 0;         for(var = 0; < sortset.length; i++){             var sort = sortset[i];             if (sort.property == "thisfield") {                 //special sort thisfield                 if (a[sort.property] !== 'undefined' && typeof a[sort.property] == "string") {                     var colora =  a[sort.property].split("|");                     avalue = colora[0].tolowercase();                 }                 if (b[sort.property] !== 'undefined' && typeof b[sort.property] == "string") {                     var colorb =  b[sort.property].split("|");                     bvalue = colorb[0].tolowercase();                 }                 if (string(avalue) == string(bvalue)) {                     result = 0;                 } else if (dojo.string.trim(avalue) == "") {                     result = true ? 1 : -1;                 } else if (dojo.string.trim(bvalue) == "") {                     result = true ? -1 : 1;                 } else {                     result = avalue > bvalue ? 1 : -1;                 }                 return result * (sort.descending ? -1 : 1);             } else {                 //sort other fields same (except tolowercase)                 if (a[sort.property] !== 'undefined' && typeof a[sort.property] == "string") {                     avalue = a[sort.property].tolowercase();                 } else {                     avalue = "";                 }                 if (b[sort.property] !== 'undefined' && typeof b[sort.property] == "string") {                     bvalue = b[sort.property].tolowercase();                 } else {                     bvalue = "";                 }                 //you need check here                  if(avalue != bvalue){                     result = avalue > bvalue ? 1 : -1;                     return result * (sort.descending ? -1 : 1);                 }             }         }         return 0;     });     currgrid.updatesortarrow(event.sort, true); }); currgrid.startup();

i have concerns code, variables result, avalue , bvalue local within if statement , yet being used outside statement. result in wrong results if other variables defined same name in global space. have modified them.

so second section needed check if avalue == bvalue return 0.
