Indicates if field names should be parsed A nested field name is a name that has a dot, for example "address.line1". If .nestedFields is true, it the record array it will expect following structure. records: [ ... { address: { line1: "line 1" } ... } ... ] if it is false, the structure should be records: [ ... { "address.line1": "line 1" } ... } ... ] This property can be set during object creation: let grid = new w2grid({ name: 'grid', nestedFields: false, columns : [ { field: 'recid', text: 'ID', size: '50px' }, { field: 'lname', text: 'Last Name', size: '30%', editable: { type: 'text' } }, { field: 'fname', text: 'First Name', size: '30%', editable: { type: 'text' } }, { field: 'email', text: 'Email', size: '40%', editable: { type: 'text' } }, { field: 'sdate', text: 'Start Date', size: '120px', editable: { type: 'date' } } ... ], records: [ { recid: 1, fname: 'John', lname: 'Doe', email: 'john@gmail.com', sdate: '1/3/2012' }, { recid: 2, fname: 'Stuart', lname: 'Motzart', email: 'stuart@gmail.com', sdate: '4/13/2012' }, { recid: 3, fname: 'Jin', lname: 'Franson', email: 'jin@gmail.com', sdate: '3/3/2012' }, { recid: 4, fname: 'Susan', lname: 'Ottie', email: 'susan@gmail.com', sdate: '5/3/2012' }, ] }); Or any time during run-time: w2ui.grid.nestedFields = false;
