jQuery File Upload - how to recognise when all files have uploaded
提问by Ankur
I'm using the jQuery File Upload plugin.
我正在使用 jQuery 文件上传插件。
I would like to be able to trigger an event when all selected files have finished uploading. So far I have an event for doing an action when a file(s) is selected for uploading and when each particular file finishes uploading - is there a way to detect that all selected files have finished uploading?
我希望能够在所有选定的文件上传完成后触发事件。到目前为止，我有一个事件，用于在选择要上传的文件以及当每个特定文件完成上传时执行操作 - 有没有办法检测到所有选定的文件都已完成上传？

$('<p/>').text("Uploading ... "+file.name).appendTo("#fileList");
});
data.submit();

c static void doUpload(File[] files) throws IOException{
List<ImageToUpload> imagesdata = new ArrayList<ImageToUpload>();
//ImageToUpload has information about images that are going to be uploaded, name size etc.
for(int i=0;i<files.length;i++){
Upload upload = new Upload(files[i]);
upload.doit(); //uploads pictures to Amazon S3
Picture pic = new Picture(files[i].getName());
pic.save(); // saves metadata to a MongoDB instance
imagesdata.add(new ImageToUpload(files[i].getName()));
}
renderJSON(imagesdata);
}

I think you are looking for 'stop' event:
我认为您正在寻找“停止”事件：
$('#fileupload').bind('fileuploadstop', function (e) {/* ... */})
as said in the plugin documentation:
如插件文档中所述：
Callback for uploads stop, equivalent to the global ajaxStop event (but for file upload requests only).
上传停止的回调，相当于全局ajaxStop事件（但只针对文件上传请求）。
You can also specify the function on plugin creation passing it as parameter
您还可以指定插件创建时将其作为参数传递的函数
$('#fileupload').fileupload({
stop: function (e) {}, // .bind('fileuploadstop', func);
});
