/** |
|
jQuery based implementation of the Plupload API - multi-runtime file uploading API. |
|
|
|
To use the widget you must include _jQuery_. It is not meant to be extended in any way and is provided to be |
|
used as it is. |
|
|
|
@example |
|
<!-- Instantiating: --> |
|
<div id="uploader"> |
|
<p>Your browser doesn't have Flash, Silverlight or HTML5 support.</p> |
|
</div> |
|
|
|
<script> |
|
$('#uploader').pluploadQueue({ |
|
url : '../upload.php', |
|
filters : [ |
|
{title : "Image files", extensions : "jpg,gif,png"} |
|
], |
|
rename: true, |
|
flash_swf_url : '../../js/Moxie.swf', |
|
silverlight_xap_url : '../../js/Moxie.xap', |
|
}); |
|
</script> |
|
|
|
@example |
|
// Retrieving a reference to plupload.Uploader object |
|
var uploader = $('#uploader').pluploadQueue(); |
|
|
|
uploader.bind('FilesAdded', function() { |
|
|
|
// Autostart |
|
setTimeout(uploader.start, 1); // "detach" from the main thread |
|
}); |
