How to generate jQuery DataTables rowId client side? -


the jquery datatables reference shows example of setting rowid option column data source (server side). setting used "select" extension , retaining row selection on ajax reload.

is there way generate row identifier value 1) client side, or 2) combination of multiple columns data source?

example data source:

{     "data": [     {         "aid": 5421,         "bid": 4502,         "name": "john smith"     } }

code:

$("#datatable").datatable({     select: true,     //rowid: "aid" each row id value of "aid" column     //       e.g., <tr id="5421">      //rowid: 0 each row id value of 0-indexed column     //       e.g., <tr id="5421"> (same above)      rowid: [0, 1] // how? row id combined value of 2+ columns                   // e.g. <tr id="5421-4502">      rowid: "random" // how? random generated client-side id                     // e.g., <tr id="id34e04"> });

apparently there's no way directly. workaround, use ajax.datasrc option and/or rowid option:

// example using datasrc option manipulate data: $("#example").datatable({     ajax: {         url: "data.json",         datasrc: function (json) {             (var = 0, ien = json.data.length; < ien; i++) {                 json.data[i][0] = '<a href="' + json.data[i][0] + '">view message</a>';             }         }     } });
