This example uses AutoComplete to find images by tag from the Flickr webservice. A simple PHP proxy is used to access the remote server via XHR. The generateRequest()
method has been customized in order send additional required parameters to the Flickr application. The formatResult()
method has been customized in order to display images in the results container, and the default CSS has been enhanced so the results container can scroll. Finally, a itemSelectEvent
handler has been defined to collect selected images in a separate container.
CSS:
1 | #flickrselections { |
2 | float:right; |
3 | width:240px; |
4 | padding:10px; |
5 | background-color:#FFA928; |

8 | #flickrselections h5 { |
9 | color:#009; |
10 | margin:0; |
11 | } |
