JQuery :: "Access Is Denied" AJAX Error, Same Origin Policy Protection With Form.js .ajaxForm()?
Jan 28, 2011
I'm having a problem with same origin policy protection using JQuery 1.4.4 and the jquery.form.js AJAX plug-in. I have an AJAX contact form which works fine so long as visitors preface URL's they type in with "www". But if they navigate directly to a URL on my site (not using www), the URL resolves OK but the URL doesn't match what I use in my AJAX form. In Chrome, this results in a console error:
(that works for mozilla based browsers) in Internet Explorer. The code above asks to the user to trust the script, so extends privileges such as same origin policy.
I have a page on local disk with 2 frames : A is a local page, B is on a server (for example http://www.google.com). I want A to access B properties (for example parent.B.location.reload() ); on Firefox it works perfectly (of course only after the consense of the user i.e me), but in IE I get a "Permission denied error".
I am trying find a way to create a specfic override to the same-origin policy between 2 frames so that I can use javascript find out the current url of frame2 from frame1.
I have read that I will need a digitally signed activex control for IE6/7 and I am not sure what is needed for other browsers.
I need this to be secure in that the override will:
- only allow frame1 (when loaded from mydomain.com) to find the current url of frame 2 - not work when frame2 is https
If this is possible does anyone know why I should not do this? If I use this in my app am I going to shoot myself in the foot?
I'm working on a project where I need to build a "web browser" within my web application. Using the iframe, I can't capture the current url and the DOM of the web page that the user is surfing. I realized that this has to do with the same origin policy guarding iframe.
I have the following 2 questions:
- Does anyone have any workable solution to overcome this issue?
- Is there any alternative to iframe so that I can let users to surf web pages within my web application? Or at the server side, I can do something?
i want to do (multiple) file upload(s) and display a progress bar. with firefox and safari it is no problem at all. only IE makes some problems.
my script is based on ajax-uploader, which can be found at www.srmiles.com/freestuff/ajax_file_uploader/ . you can do multiple file uploads. each upload will have it's own "form"-tag, so that each file is uploaded for its own. could be a good solution if there are "big" uploads.
so here is what i do:
i have a html-page in which several forms with file-input fields are generated. when i now hit the "one" submit button at the bottom of the page a javascript function upload() starts it will iterate through all forms (id='frmUpload_xx'), will get the filename, start a ajax request for the progress-bar function and do a form.submit().
if the first form/file is uploaded, a settimeout('upload()', 1000); is called and the next form will be processed. all form's have an target="uploaddiv", where uploaddiv is a invisible iframe. so the output of the upload script is put in this div. output should only be a "OK" at the end. no usefull output no info no nothing.
firefox and safari are working as expected, only IE stops after the first file is uploaded. i get an javascript error saying "zugriff verweigert/access denied" on object line x... this is the place where i call "form.submit()".
this is the upload-function:
function upload() { if (uploads.length>0) { form = document.getElementById('frmUpload_'+uploads[0]); if (form["filename"].value == ""){ alert("Please Choose a file to upload."); } else { filename = form["filename"].value; if (filename.lastIndexOf("")>0) { filename = filename.substring(filename.lastIndexOf("") +1,filename.length); } else if (filename.lastIndexOf("/")>0) { filename = filename.substring(filename.lastIndexOf("/") +1,filename.length); } makeRequest("upload_progress.php?sid="+sid +"&filename="+filename,progress); form.submit(); } } }
the strange thing is, that filename is filled correct, that means the object "form" is found and exisits. the first iteration is working, only the second ends with an error.
think it have something to do with redirecting the output of the upload-script in an iframe. after that IE can't access form - at least IE is not allowed to submit the form as i can access a form field (filename). i worked on that the last two days and haven't found a solution...
I stumbled on this problem while testing StatusNet for our next release; we use jquery.form's .ajaxForm() to do various AJAX form submissions, including the primary message-sending form which includes a file upload control.
We've not seen problems before, but since upgrading from an old Form plugin version 2.17 to 2.49 a couple months ago, I've noticed our development branch no longer works properly in Opera: the actual submission goes fine, but we're unable to access the XML return data (which usually contains HTML fragments to put back into the UI).
I have a test case which demonstrates this at [URL] (source of the main page & submit handler are included there), using current jQuery 1.4.4 and jquery.form 2.52.
Under Firefox 4.0b10 and other browsers, the forms submit correctly, and we can read nodes and text out of the returned XML just fine.
But on Opera 11.00 and 10.63, the submission goes through but we get back an HTML document containing only "<head></head><body></body>". On Opera 9.63, it also includes the text "Blank page."
I tried to trace this down in jquery.form's history, and the trouble seems to have started around 2.39 with a commit ironically titled "iframe load fix (mostly for Opera)", which changes the event handling for forms submitted via iframe: from that version on, a 'load' event handler is added directly as an onload attribute on the iframe's source, whereas previously it was added with attachEvent or addEventListener.
It looks to me like the iframe is throwing a load event for the "about:blank" page, instead of for the submission.
I can revert back to 2.17 or another working version for now, but I'd like to make sure this is fixed upstream;
I have to open a file control on button click and need to upload a file on selection. For this what i did is,
1. Made file control hidden. 2. called filecontrol.click() function on button click. 3. called an iframe for image uploading by submitting the form on "onchange" event of file control.
When iam submit the form through javascript, "Access is denied" error is coming.
I got this working in FireFox if I changed headers to Access-Control-Allow-Origin: * With IE7 I'm getting "Access is denied" error. And with IE7 I can't use XDomainRequest.Is there some workaround besides creating proxy? Like using another request method(PUT?)?
All I'm doing righthere is calling a Perl script on an intranet server and using the xml results to popluate a <select> element. This works on my machine but a co-worker is getting a "Permission Denied" error when this function is executing onReady
function populateGroups(){ var p = 1; var groupNames = new Array(); $.ajax({ type:"GET", .....
I had him run a tracert to that server and we all connected through the same network devices... And this works on a couple of other co-worker's computers. He also does have access to that server so that he can type in the url and get the xml results...
I am getting an error to a mysql_query() call: Access denied for user 'SYSTEM'@'localhost' (using password: NO)' in path 'C:PHPClassesMySQLDbClass.php' at line 1078 This is coming from using a XML HTTP Request object (AJAX) to send form data to the server requesting my DB records interface script page, ajaxRecordsInterface.php. In using PHP sessions, I have no problem going from a logged-in-select-activity PHP document to an activity controlled by a PHP document that does records interface. But apparently an XML HTTP Request object has a different session than a PHPdoc-2-PHPdoc session. Is that so?
Here is MORE DETAIL: I am building first a version of a web-based database interaction using MySQL that does not use page reloads, so that means I am using Ajax/XML HTTP request object/Javascript (later I build the version that does script-free page reloads to show db updates/refreshes). I have no problem with login whose first PHP document gets user information and presents it, as well as a menu of links to how to interact with the DB. One of the options is to add/edit/delete student records.
In the PHP document which is the DB records interface, I have a scrollable HTML table at the document top with one table row for each record. Below it is an empty form, whose fields get populated when the user clicking on a record in a table row. Note that all fields for the records in the table rows were delivered as a Javascript array with a maximum of 50 or a 100 contiguous records in the MySQL table. (More optimizations may be done later, such as creating a Javascript array as a "cache" of the last 20 or so selected records.) I don't have problems making mysql_query() calls in a series of PHP document requests. I call session_start() to get session variables, one of which is a serialized MySQLDatabase class object which I unserialize to get the object again. The problem is the XML HTTP Request to a PHP document designed to interact with it is a different PHP session from a page-to-page session.
I'm getting an incredible behaviour of internet explorer. I have a generated html page with one form and many input of checkbox type.
Those checkbox are grouped in 4 lists and each list of checkbox contain checkboxs with the same name so I can easily retrieve on my server side (java) wich checkbox are checked with a request.getParameterValues(). (Each checkbox has a value corresponding to the id of the row) Anyway that's not on the server that the problem is.
Here it comes. When more than 132 checkboxes are checked, my form submit generate a javascript error. When 132 or less checkboxes are checked it submit without problem.
I tested the page with firefox, the problem is not here with that browser and it can submit liek for example 400 checkboxes.
Then I tried to make a workaround, on submiting I browse the elements list of my document and I create a big string containing all the ids checked and then I uncheck all checkboxes and submit. there again it fail to work.
I'm really affraid I'm looking at a nasty bug of Internet explorer here and I'm going to engineer a more deep workaround if noone can point out a solution to me.
I should precise that I have no iframes on that page. I indeed saw that some people got 'access is denied' on submit form but in my case it works when not too much data is going to be submited !
I want to add this calculator form to our website (here is the link to what he wants exactly [URL]) so I try to copy that code but it won't work. I was wondering if this javascript would work.
My understanding of "Access is denied" with respect to window.moveTo is that it results from a request which would move a portion of the window off screen.
The window in question is 480 high by 1000 wide. The screen dimensions are 1024x768. The move request is to 10,10, which would put the max right coordinate of the window at 1010 and the max bottom coordinate at 490. Both coordinates are clearly within the accessable area of the screen.
The code works fine on server A, but not on server B. Both servers are identical environments (SuSE Linux, Apache, all the same versions). Not only that, the code works fine using Firefox on either server. Only IE throws the error, and only on server B.
I am working with a toolbar. I have a function where i need to capture the colors userd in that page and display in another html page by popping up.
for that i am using the below code. This code is working fine when i am working with my local webserver when i tested in separate html pages. but when i kept it in the toolbar and calling the js file, it says "Access is Denied".
I worked with this functionality for 4 days and tried to debug. but no use. finally i am keeping this problem in net.
The following javascript code generates an "Access denied" error at the indicated line.
This sample should allow the user to click "Browse" and choose a file. Once the user has selected a file the form is automatically submitted. I'm trying to avoid having seperate browse and submit actions.
Can someone explain why I'm getting the error and how I can accomplish this task? Code:
I'm doing a JSONP query of a Wordpress database. Example call:[URL].. This code returns the expected data when executed on my local server. It also returns the expected data when I upload it to one of my remote servers. But it fails when run from the root of the domain it's calling, [URL]... no data is returned. (Behavior is the same for latest versions of Firefox, Safari, Chrome.)
I think there's something really simple going wrong here but don't know what it is. The only clue I have is provided by Firefox: When run successfully, all of the GET's appear in the JS subpanel of NET. The failed calls, launched from the domain containing the database, are listed in the XHR subpanel with a status of "301 Moved Permanently".
I want to call C# method from jquery. So, I placed those methods in webservice and trying to call from jquery. But, it is giving an error as shown below: Access to restricted URI denied" code: "1012 This is seen from the Firebug console.
few days ago I wanted to post a follow-up to an issue reported on my plugin on [URL] just to find out some really weird things are happening there.
First I couldn't post the reply with an error telling me I didn't select any project. So I checked the dropdown list of projects to manually find the Reel project. It isn't in the list.
Then I tried to search for Reel project. With no luck.
I also tried a breadcrumb link on the issue page which finally led me to my project page - [URL] where I saw another unusual thing - a pink background underlying the page.
So I filed an issue there -[URL]
But things got much worse today...
Now when I'm logged in i see "ACCESS DENIED" nearly anywhere I look - jQuery Plugins Website Issue Queue, my plugin homes, my issues, the support request I filed, even on the jQuery Plugins homepage.
Under My Projects there's "You have no projects". Even though my other plugin - [URL] - seems to still exist
I have two projects there and even when I'm not logged I'm able to see just one (longclick), the other (reel) gives me access denied.
I'm also denied to post a follow-up to my support request, hence I'm posting here.
some jQuery Plugins Website insiders? what the heck is going on with my account and my Reel project?
I am developing a web page . For this i am using Javascript embedded in html. In the application ,the user can input data via interfaces in the page which is chosen and read from a master xml file , the chosen data then needs to be stored and saved in a xml file.I have designed the web page in FrontPage.
Now the problem i face is while trying to save the output xml file i get error Permission Denied , error code 0 . This happens when i try to open the page in browser IE 6.0 SP2.I am using DOM parser methods for doing the xml manipulations/savings etc.urprisingly this works in another machine.Also can i use the all of the same javascript code if i want to run it in an IIS. Do i have to do some changes to make it server side javascript code.
I cannot seem to fix this problem; I get an access denied error with the line colored red below. I am not calling this up from another domain, it is simply a popup that has a few parameters. Works fine in Firefox. code...
My HTML page loads and alerts an XML document on another machine. If I request the page by machine name or localhost there is no problem. If i request by IP access denied error occurs.
I think this is because of that only the documents on same machine can be loaded. Is there any way to load xml documents from another machine?
