| <h1>How to create knockout nested components</h1> | |
| <p>Note that this code is reliant on require.js and knockout</p> | |
| <p>Components should be placed in a folder structure as follows: /Components/name/(view/viewmodel)</p> | |
| <nifty-list-item params='labelText:"component that isnt nested"'></nifty-list-item> | |
| <nifty-list params='componentText:"text passed to component"'> | |
| <nifty-list-item params='labelText:"nested component 1"'></nifty-list-item> | |
| <nifty-list-item params='labelText:"nested component 2"'></nifty-list-item> | |
| <nifty-list-item params='labelText:"nested component 3"'></nifty-list-item> | |
| </nifty-list> | |
| <script> | |
| ko.components.register('nifty-list', { | |
| viewModel: { require: 'components/nifty-list/viewmodel' }, | |
| template: { require: 'text!components/nifty-list/view.html' } | |
| }); | |
| ko.components.register('nifty-list-item', { | |
| viewModel: { require: 'components/nifty-list-item/viewmodel' }, | |
| template: { require: 'text!components/nifty-list-item/view.html' } | |
