 var ids = new array();   $('#file_upload').uploadify({         'uploader': swfurl,         'script': ashxurl,         'cancelimg': cancelurl,         'folder': uploadsurl,         'auto': true,         'fileext': '*.jpg;*.gif;*.png;*.psd;*.jpeg',         'filedesc': 'graphics files',         'removecompleted': false,         'buttontext': 'upload psd',         'multi': true,         'queueid': 'divparent',         'oncomplete': function (event, id, fileobj, response, data) {             ids.push(response);         }, 'onselect': function (event, id, fileobj)         {              alert(event.target);             alert($(event.target).prop('id'));             customfilearray.push({ id: id, file: fileobj, upload: false });         }     }); 

to value call following code.

 $("#ids").val(ids.join(',')); 

just omit unwanted code have used , think enough understanding
