问题 The problem I've got is that I'm calling a php script on my server via XMLHttpRequest from a page that has already a session cookie set. The problem is that the script called by my page creates a new session_id for each call and does not use the existing one to store, the information I want to set, in it. Any solutions? Best regards, pbcoder 回答1: You're probably regenerating the session in your server side file .... can you post the part that checks the session here ? You can set a specific

问题 I'm working on making an AJAX request from a Firefox extension. I have this code: function GetMenu(){ var oReq = Components.classes["@mozilla.org/xmlextras/xmlhttprequest;1"].createInstance(); // Setup event handlers - must be set before calling open() oReq.addEventListener("progress", updateProgress, false); oReq.addEventListener("load", transferComplete, false); oReq.addEventListener("error", transferFailed, false); oReq.addEventListener("abort", transferCanceled, false); oReq.open('POST',

问题 I am trying to send JSON data from a form using the XMLHttpRequest object. I can send the data using the following function. There are no errors displayed in FireBug and the JSON-data in the request is displayed well formed by FireBug. However, I send the data to echo.php , what simply returns the content: <?php print_r($_POST); print_r($_GET); foreach (getallheaders() as $name => $value) { echo "$name: $value\n"; } echo file_get_contents('php://input'); ?> The POST-array is always empty, but

问题 I've been trying to get Chrome to load and transform local files. I can attach a style sheet to XML files and that works fine (once the --allow-file-access-from-files switch is added to the command line). However, when trying to load files using xmlHTTPRequest pretty much exactly as in the question Loading local XML file in Chrome (see below), it fails on the line xmlHttp.send(null) . Does anyone know why or can offer assistance? Here's the code from that question: function readxml() {

问题 I want to know how to abort a request. For example, I issue App.MyModel.find() and later i want to cancel/abort it before it returns from server. I would expect something like this: var res = App.MyModel.find(); //request sent to server res.abort(); // abort the request before completion but this doesn't work - the returned object is a promise and there is neither abort nor cancel methods. Clarification I'm looking for how to call the abort method on the underlying XMLHttpRequest object. 回答1:

问题 I want to upload and then process a file in a Ruby on Rails app. The file upload is usually quite short, but the server-side processing can take some time (more than 20 seconds) so I want to give the user some indicator - something better than a meaningless 'processing...' screen. I'm trying to use the following code in the view <%= periodically_call_remote(:url => {:action => 'progress_monitor', :controller => 'files'}, :frequency => '5', :update => "setProgress('progressBar','5')" ) %> The

问题 I am trying to upload local mp4/move file with XMLHttpRequest() on a server. This is written with react-native and in final version user would be able to upload any big files from his/her IOS/Android device to server. The file is about 1 GB (it could potentially be from 100 mb to 10 GB). With files below 70 mb I could easily use this code ( below ) to load the blob then slice it and put on server using : https://github.com/inorganik/digest-auth-request sendRequest = new digestAuthRequest('PUT
