Function to parse server response. If you server returns record structure different front what grid requires, you can define a parse function that will be called when data is received, but before when it is merged into the grid. This property should be set during object creation: let grid = new w2grid({ name : 'grid', url : '/server/side/url', columns : [ { field: 'recid', text: 'ID', size: '50px' }, { field: 'lname', text: 'Last Name', size: '30%' }, { field: 'fname', text: 'First Name', size: '30%' }, { field: 'email', text: 'Email', size: '40%' }, { field: 'sdate', text: 'Start Date', size: '120px' }, { field: 'sdate', text: 'End Date', size: '120px' } ], parser: function (responseText) { var data = $.parseJSON(responseText); // do other things return data; } });
