 <script type="text/javascript">  // convert divs queue widgets when dom ready $(function () {     $("#uploader").pluploadqueue({         // general settings         runtimes: 'gears,flash,silverlight,browserplus,html5',         url: '<%: url.content( "~//uploades/horses/" ) %>',         max_file_size: '10mb',         chunk_size: '1mb',         unique_names: true,          // resize images on clientside if can         resize: { width: 320, height: 240, quality: 90 },          // specify files browse         filters: [         { title: "image files", extensions: "jpg,gif,png" },         { title: "zip files", extensions: "zip" }     ],          // flash settings         flash_swf_url: '../../../../scripts/plupload/plupload.flash.swf',          // silverlight settings         silverlight_xap_url: '../../../../scripts/plupload/plupload.silverlight.xap'     });      // client side form validation     $('form').submit(function (e) {         var uploader = $('#uploader').pluploadqueue();         uploader.refresh();         // validate number of uploaded files         if (uploader.total.uploaded == 0) {             // files in queue upload them first             if (uploader.files.length > 0) {                 // when files uploaded submit form                 uploader.bind('uploadprogress', function () {                     if (uploader.total.uploaded == uploader.files.length)                         $('form').submit();                 });                  uploader.start();             } else                 alert('you must @ least upload 1 file.');              e.preventdefault();         }     }); }); 

<div id="uploader" style="height:300px">         <p>you browser doesn't have flash, silverlight, gears, browserplus or html5 support.</p>     </div> 

if try debug uploadingelemt showen out problems. if click add files window jumps top of page , nothin else happens.

firebug not show problems.

i've tried in ff4 & ie 8 using flash , silverlight

any 1 idea? thank , wish nice weekend!

your browser use flash runtime listed before 'html5'. flash runtime requires setting of 'container: "my_uploader_container_id"'

and 'pickfiles' button need placed div id 'my_uploader_container_id'.

another solution using html5 engine - list before flash in 'runtimes' parameter. html5 runtime not work in ie.
