|

<p>In this example, the Uploader is used to send multiple images or videos to the server and monitor |
|
|
30 |
their upload progress with individual counters. If the Uploader is used in a browser with HTML5 |
|
|
31 |
support, it is progressively enhanced to enable dragging-and-dropping files into the browser window.</p> |
|
|
32 |
|
|
|
33 |
<p><strong>Please note:</strong> This example will not work when run from a local filesystem because of security restrictions in the transport protocols used. If you’d like to run this example locally, set up a local web server and launch it from there.</p> |
|
|
34 |
|
|
|
35 |
<p><strong>Also note:</strong> The uploader is not supported on iOS devices (iPhone and iPad), because they lack file upload capability. This example provides a graceful degradation message for all such systems.</p> |
|
|
36 |
|
|
|
37 |
<p><strong>Also note:</strong> The backend script used in these examples does not store any information it receives. Nevertheless, do not submit any sensitive or private data and keep |
|
|
38 |
your tests to a few small files to avoid overloading the system.</p> |

<h2>Progressive Enhancement with a Drag-and-Drop Area</h2> |
|
|
201 |
|
|
|
202 |
<p>The base functionality in this example is the same as in the <a href="uploader-multiple.html">Simple Multiple Files Uploader</a>, but we are conditionally adding support for a |
|
|
203 |
drag-and-drop area for cases where the HTML5 uploader is being used:<p> |
|
|
204 |
|
|
|
205 |
<pre class="code prettyprint">if (Y.Uploader.TYPE == "html5") { |
|
|
206 |
uploader.set("dragAndDropArea", "body"); |
|
|
207 |
Y.one("#ddmessage").setHTML("<strong>Drag and drop files here.</strong>"); |
|
|
208 |
|
|
|
209 |
uploader.on(["dragenter", "dragover"], function (event) { |
|
|
210 |
var ddmessage = Y.one("#ddmessage"); |
|
|
211 |
if (ddmessage) { |
|
|
212 |
ddmessage.setHTML("<strong>Files detected, drop them here!</strong>"); |
|

|
|
224 |
}</pre> |
|
|
225 |
|
|
|
226 |
|
|
|
227 |
<p>Note that we are setting the entire page <code><body></code> as the drag-and-drop area, so the user can drop the files anywhere onto the page. We also add a visual response to the files |
|
|
228 |
being dragged over the page by listening to the <code>dragenter</code>, <code>dragover</code>, <code>dragleave</code> and <code>drop</code> events. |
