I am using jquery.ajax() to make a POST call to web server which returns HTTP 201 response for successful creation of object at server. Since 201 is a success I expect the success function specified with jquery.ajax to execute but instead it executes the error function specified with jquery.ajax. Here is how I am using jquery.ajax call.

I'm having problems performing a simple load(...) request to bring in HTML content from a partner Oracle system within the same domain. Our portal has a built-in SO connection will handles security for me transparently. However during the process it initiates a 302 temporarily moved response which seems to trip up an AJAX request, but doesn't trip up Firefox when accessed through the address bar. If I use the same URL in an IFRAME it's totally fine.
After tons of googling, searching the forums, and the bug tracker database I cannot find anyone who has experienced this problem. Before I open a bug ticket I'd like community feedback to help me see if I am doing anything wrong.
My AJAX call looks like this in Javascript:
Is it possible to take a url from a text box and request the HTTP Response Header and then document.write() it? I'm envisaging a form into which a user can enter a url and receive the Response Header information. Could I achieve this with JavaScript?

I have a site that I've put a lot of time and effort into and in the midst have also been using it to learn JavaScript. I'm pretty proficient at PHP so the site was mostly coded in PHP, but now I've decided it would be best use Ajax to update the mySQL database instead of PHP so my pages don't have to refresh every time a change is made.Are there any references that you know of that could help me out in the conversion process?Most of my PHP scripts POST back to themselves and I use if(isset($_POST)) to update the info on the mySQL database. I'm still a novice at JavaScript and Ajax.

Some times the PHP server that hosting my site become down, while, the server still executes the html and JavaScript. I am looking for a method that resolves the response code of a page (e.g.: 404, 500) and redirect the user agent to another url. Can JavaScript help me in this case?
View 2 Replies View RelatedI am trying to load something in a tab using AJAX. However it will not work if the URL is using http, for example, [url], or [url].
I know the HTML and JS is fine as it will load files that do not have http, like the third list item in the example.
EXAMPLE:
I cannot understand why this is.
I am doing xmlhttp ajax stuff. I am using a script called "SEXYALERTBOX". I am using it to allow the user to input a password. The textbox is called BoxPromptInput. I do not think its inside a <form> tag.
Here is the code:
function askForPass() {
Sexy.prompt('Please type the password in order to see the pictures/videos','' ,{ onComplete:
function(returnvalue) {
if(returnvalue) {
var xmlhttp = false;
var pageResponse = null;
try{xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");}
catch (error){try {xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");} catch (error) {xmlhttp = false;}} .....
Any way to pass the value since I am sure the request.form would not work in this case since its not in a form.
I am writing one iframe dynamically from my code like below. document.write("<iframe src='" + location + "?querStr=" + querStr"' width='0px' height='0px'></iframe>"); location is something like - [URL] and the querStr is some parameters passing to the iframe. querStr contains some parameters which have timestamp appended. So the request url is always unique. In IE/FF2 i am seeing proper unique request (200 response code) but in Firefox 3, the url is getting cached. From my code (before sending the request) i can see proper generation of the request but actually the request url gets cached. I saw it using fiddler and the response code is 304.

View 2 Replies View RelatedI have an application running on a non-interactive kiosk that I need to keep updated with information that will be provided by a remote server. To do this, I've created an XMLHttpRequest/Microsoft.XMLHTTP object that checks the modified date in the header of a watched file that resides on a remote server.
This function runs on an interval, and if it detects a change in the modified date since the last check, it retrieves new information from the remote server.

It's my first post/thread here, I haven't been active in forums for some time cause frankly I didn't need it, but this one just got me. I tried everything in my knowledge -and I mean everything, I'm a fanatic trial-and-error tester. Situation: jQuery, posts some data through Ajax collected primarily from a $('#textarea') to a php file on server. If the data is >X Bytes, I get 404 Not Found and the 404 Html page in Ajax error handler. Otherwise, everything runs smoothly and I get my results. I must specify that I post to a php file that loads Wordpress's wp-blog-header.php before doing calculations, as the code is intended to be part of a WPplugin.
I tried to return header("HTTP/1.1 200 OK") as some suggested, considering WP was altering the header for not finding the file as part of the system, and it solved the issue locally for some cases, but not remotly.
I tried to set the Content-Length in ajax call. I switched between the WP type of handling Ajax calls, and having my own .php file, in the folder of my plugin. Nothing worked, but trimming content. What could this be? post_data_size is 8M on server. Could this be maybe related to SSL as I've seen in some cases?
$.ajax({
url: "someurl.php",
success: function(data){
//..process on success..

I want to reload the page if session is timed out so I am checking the user session at PHP file and if session is timeout I am sending error code. if I get the error code in response I will reload the page so that it will load login page.
As the title implies, i need to make use ajax with GET method and with data in the http request body. I can do it with POST method but i don't know how to do it with GET. In php, it's easy...

Initially I (successfully) tested my project after deploying to the Apache server which is running in the localhost.
But, if I just open the page in a browser (without deploying to the server), the project works fine! How this is possible?
According to my understanding, if we send an AJAX request, which is really an HTTP request, which has to be received by an HTTP server and the response should come from the server.
I've been reading a lot about Comet and I've been interested in implementing it. It doesn't sound that difficult, but I have yet to find concrete examples of what it is, so I don't know how to actually use it.
I've seen some examples where new ajax requests are made as soon as old ones are complet but this doesn't make any sense to me. It seems this method is a complete resource bandit.
For example, how do I open a long-lived HTTP request? If the request is long-lived, when does the callback get actually called - at the very end of the request (status == 200 and readyState == 4) or can I call it intermittently to download new data while my PHP script is in sleep()-ing?
I've created an item tooltip that appears when an image is hovered. When the image is hovered AJAX fetches information from 'getItemInfo.php' and places inside the '#ng-item-info' DIV The parameters for the .php file are stored in the image rel in the following format: " ITEMID, GUID ( not used ) " The problem I am facing is that whenever I hover over another image, for example one with the ID of 3, the information for ID 1 is ALWAYS displayed.
$(document).ready(function() {
var itemicon = $('.ng-item');
var iteminfo = $(itemicon).attr('rel').split(',');

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.
Some servers return JavaScript as the response to an AJAX request. When
the response JavaScript is eval'ed it calls other JavaScript functions
already in the browser to update elements, etc. This seems like a good
system because it allows so much freedom in creating the desired
behavior in the browser. The required data doesn't have to be converted
to XML or JSON on the server. The browser doesn't have to have
templates for interpreting and converting this data into some change in
the browser. All of the conversion algorithms don't have to be written
and changed when new behavior is required. This remote procedure call
approach is the predominant system in the Ruby on Rails world.
(Unfortunately they are calling Prototype.js functions.)
However apparently some people seem to think this remote procedure call
approach is a bad idea. I can't see why it is so bad because it is so
lightweight and flexible. It also helps to keep the client less
intellegent which seems good in a world of incompatible client-side
bugs.
If I use some neutral data format like XML to accomdate different types
of clients then I have to write different client-side interpreters for
each type of client (browser, RSS, POP, cell phone, etc). Why not just
write different server-side code that generates the correct JavaScript
(or other) for the requesting client type?
When is the RPC approach such a bad idea?
I am using ajax / php where I am looking up some info from the
database and populating a select list dynamically, however I am
running into some sort of size limitation with the ajax.response
object. If the string I am passing to javascript from php is too large
javascript does not get it all the data. The magic number appears to
be 6123 characters, anything below that it works fine, anything above
and if I alert the ajax.response, I see the string is cutoff. Any
ideas where this limitation is defined?
I am using following code
Now what i want to do is: i have a callajax() function. with in this function i will call do_login() function. this do_login() handles an ajaxrequest and returns the responsetext.
Now i want to do some validation on this responsetext(in case of onsuccess). so i am trying to return value to callajax() function for onSuccess case in ajaxrequest.submit();
That is(onsuccess response) supposed to be some string( but not true or false). but i am always getting false in ajaxcall() function. i know the do_login() function is returning false before ajaxrequest completes
So i want to stop this and make do_login wait until ajaxrequest completes and then i want to return it's response to callajax() function.
I am wondering how possible it is to use eval() to parse javascrpt that is pulled in through ajax(innerHTML)? I have found a few notes about this, such as:
Code:
var myObj = eval ( xmlhttp.responseText );
In my browser, I make an AJAX request. The server sends me a fragment
of an HTML document. That fragment has some JavaScript inside some
script tags. How do I run these scripts when the fragment arrives at
the browser?
