Simple Sort Sample For Slickgrid

I want to havesimple slickgrid column sort. however I might not understand the basic idea. what I have done is like this. Make column sortable {id: 'score', name: 'number', field:

Solution 1:

Check out the examples here. There is no default sorting in the grid - this is left to the datasource to manage.

This example uses the native javascript sort property of the source data array to sort the rows:

grid = new Slick.Grid("#myGrid", data, columns, options);

grid.onSort.subscribe(function (e, args) {
  var cols = args.sortCols;

  data.sort(function (dataRow1, dataRow2) {
    for (var i = 0, l = cols.length; i < l; i++) {
      var field = cols[i].sortCol.field;
      var sign = cols[i].sortAsc ? 1 : -1;
      var value1 = dataRow1[field], value2 = dataRow2[field];
      var result = (value1 == value2 ? 0 : (value1 > value2 ? 1 : -1)) * sign;
      if (result != 0) {
        return result;
      }
    }
    return 0;
  });
  grid.invalidate();
  grid.render();
});

This example outsources the sorting to the DataView object which is the grid's datasource.

grid.onSort.subscribe(function (e, args) {
  sortdir = args.sortAsc ? 1 : -1;
  sortcol = args.sortCol.field;

  if (isIEPreVer9()) {
    // using temporary Object.prototype.toString override
    // more limited and does lexicographic sort only by default, but can be much faster

    var percentCompleteValueFn = function () {
      var val = this["percentComplete"];
      if (val < 10) {
        return "00" + val;
      } else if (val < 100) {
        return "0" + val;
      } else {
        return val;
      }
    };

    // use numeric sort of % and lexicographic for everything else
    dataView.fastSort((sortcol == "percentComplete") ? percentCompleteValueFn : sortcol, args.sortAsc);
  } else {
    // using native sort with comparer
    // preferred method but can be very slow in IE with huge datasets
    dataView.sort(comparer, args.sortAsc);
  }
});
