asyncfileupload

问题 Is it possible to do an AJAX form submit without jQuery or IFrames (so just pure JavaScript)? I'm currently sending to a struts fileUploadAction that works. Would the action's code still work with the asynchronous submit, or are there additions required to pick up the async form submit? I am using struts 1.x and current my form is: <html:form action="fileUploadAction" method="post" enctype="multipart/form-data"> ...form elements... <html:file property="theFile" /> ...other elements... </html

问题 I'm trying to debug an asynchronous file uploader that I built some time ago which is no longer working, I've spent already a good deal of time without success. The stream that the server is receiving is always corrupted in fact the file (image) that I save cannot be opened. To simplify debugging I have setup a brand new ASP.NET project, with two main files, the HTML file with the form field and the ASP.NET handler. Despite the code here being very trivial, I'm still out of luck! :( Any help

问题 It seems that nginx buffers requests before passing it to the updstream server,while it is OK for most cases for me it is very bad :) My case is like this: I have nginx as a frontend server to proxy 3 different servers: apache with a typical php app shaveet(a open source comet server) built by me with python and gevent a file upload server built again with gevent that proxies the uploads to rackspace cloudfiles while accepting the upload from the client. #3 is the problem, right now what I

问题 I'm using sails.js to build a website. I have a model named timeline . It has some text fields along with a collection named pictures . Each timeline can have multiple pictures . I want to update all these fields at once when user clicks save . I'm using JQuery file uploader to help multifile upload. Problem is, JQuery file upload calls my backend file-uploader service once for each picture uploaded. I need to update the other text fields only once and they need to be updated before the

问题 I implemented the AsyncFileUpload control on a web page. This web page requires uploaded files to appear in a GridView . The GridView contains the following columns: " File Name ", " Confidential " Check Box, and a " Remove " button to remove the uploaded file. Since the AsyncFileUpload postback does not do a full page postback, I need to "force" a postback on the OnClientUploadComplete event of the AsyncFileUpload control in order to render the gridview after uploading a file. In the

问题 I've been learning quite a bit from everyone here, however I've come across a problem which I'm having trouble finding an answer to. While attempting to save an image which has been uploaded using AsyncFileUpload I'm receiving the following error: A generic error occurred in GDI+. I've done quite a bit of Googling and it seems that the most likely issue is permissions related. I've tried allowing write/modify for Network and Network_Serice. Later attempted allowing it for the environment user

问题 I am trying to send/ upload a value from an file type input along with data from text inputs to the my do_upload() function in CodeIgniter. I been researching here and on other websites about how to do this and applied the codes in mine, but with no luck yet, it still won't work. I do not want to use FormData since I don't wanna add a <form> element on my "form". Here is my jQuery and Ajax: $("#create_post").click(function(e){ var post_title = document.getElementById("post_title").value; var
