Removing Things
Removing an element from the document is quite Darty.
| dom/removing.dart | |
| | document. |
| | query('#content'). |
| | query('#gallery'). |
| | remove(); |
This would find the element with the ID of "content"; then, inside that, it would find the "gallery" element and remove it from the page. If the page began:
| | <body> |
| | <div id="content"> |
| | <div id="gallery"/> |
| | <p class="instructions">...</p> |
| | </div> |
| | </body> |
then the result of the previous remove would be as follows:
| | <body> |
| | <div id="content"> |
| | <p class="instructions">...</p> |
| | </div> |
| | </body> |
Not being required to walk up to an element’s parent to remove the element, as we have to do in JavaScript, is a nice win.
