Updates specified cells Returns time it took to update (in milliseconds).

Description

This method is super fast and update grid within a few milliseconds (grid.refresh() in comparison take about 30-80ms depending on the data). It will only update records within the virtual scroll and those that changed. If called without arguments, it will update entire grid. If column value did not change, (DOM has same html as what grid.getCellValue() returns for the specified cell), it will not reinsert HTML into the DOM. The update function will transform data through renderers, and also take into account classes and styles defined on the column or record level. It will keep current selection in the grid, if any. The options { cells: [], // array of { index, column } pairs to update fullCellRefresh: false, // weather full-cell refresh is needed (TD level), othewiser only inside TD` ignoreColumns: [] // array of column indexes or column field names } If you have following grid: let grid = new w2grid({ name : 'grid', 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: 'End Date', size: '120px' } ], records: [ { recid: 1, fname: 'John', lname: 'doe', email: 'vitali@gmail.com', sdate: '1/3/2012' }, { recid: 2, fname: 'Stuart', lname: 'Motzart', email: 'jdoe@gmail.com', sdate: '2/4/2012' }, { recid: 3, fname: 'Jin', lname: 'Franson', email: '--', sdate: '4/23/2012' }, { recid: 4, fname: 'Susan', lname: 'Ottie', email: 'jdoe@gmail.com', sdate: '5/3/2012' }, { recid: 5, fname: 'Kelly', lname: 'Silver', email: 'jdoe@gmail.com', sdate: '4/3/2012' }, { recid: 6, fname: 'Francis', lname: 'Gatos', email: 'vitali@gmail.com', sdate: '2/5/2012' } ] }); Update what's changed: w2ui.grid.records[2].fname = 'Another' w2ui.grid.update(); Update specific cells: w2ui.grid.records[2].fname = 'Another' w2ui.grid.update({ cells: [{ index: 2, column: 1}] }); Update all cells on screen except cells in the specified columns: w2ui.grid.update({ ignoreColumns: [0, 'email'] }); // can be either index or column.field Update all cells that changed with full cell refresh (not frequent): w2ui.grid.update({ fullCellRefresh: true });
