Unique name for the object. All objects (regardless of type) are registered as w2ui[name], where w2ui is a global variable. The name of the object must be unique, otherwise object will not be created. // layout let layout = new w2layout({ name : 'layout', panels : [ { type: 'top', size: 40 }, { type: 'preview', size: 200 } ] }); // grid let grid = new w2grid({ name : 'grid', columns : [ { field: 'fname', text: 'First Name', size: '30%' }, { field: 'lname', text: 'Last Name', size: '30%' }, { field: 'email', text: 'Email', size: '40%' } ] }); In the example above two objects are created - a layout and a grid. You can access them through a global variable w2ui in the following way: w2ui.layout.refresh(); // layout grid.refresh(); // grid You can destroy any object by name $().w2destroy('layout');
