Redirect Of Ajax Call - How To Check?
Feb 27, 2006
Does anyone know is it possible to check if ajax call was redirect? i mean I connect by Ajax to one URL but I'm redirected to other url. Is there a way to check that my request was redirected? this situation happen when some urls are only accesible when you are logged (i mean you have session) and if you losed session you are usually redirect to other page. But I don't know is it possible to check that my call was redirect. For now wheatever my AJAX call was redirect or not i get status 200 (it's OK)...

This is my first adventure into PHP/Ajax/MySql/Javascript and is pretty much my first web project. I've been trying to tackle this problem for a little over a week now. My main objective is that I want to display php content pages inside a div on the index page without refreshing the page (iframe style). I don't want to stop search engines indexing the individual pages so I need a mechanism to redirect to the index page so that the page is displayed properly. I'm not bothered if it takes them to the exact page and I'm redirecting them to the section of the site where they the page is kept.
I also want a mechanism to redirect if a second search engine link is clicked that belongs to the individual page (ie image links that belong to the same page). This is only a problem because the php session has already been opened and a php variable has been set by the first redirect. All the redirections are taken care of by PHP and I got the redirection of multiple instances working ok by setting and unsetting session variables. This PHP code is included on every content page.
But, when I added links to the index page and try to navigate between pages, it all goes pear-shaped.When the links are clicked it calls up the Javascript code, inside which a PHP variable is set (I dunno if this is the "done" thing, but I came across the solution somewhere on the Interweb). This is the first thing checked when the content pages are called up. If the variable isn't set, then it runs through the redirect options.
The problem is that after clicking the link when the page displays it always refreshes the index page which I don't want it to do and which is why I'm thinking it's the setting of the PHP variable inside the Javascript that's going wrong. (Also why this question ended up in this section). Is there any way of getting this going without passing the variable into the url (not that I'm against this option)? Index page code, PHP Code (before HTML)...
Code:
<?php
if(!isset($_SESSION))
{
session_start();
}
// set the session var to the index page url which I think remains until browser close
$_SESSION['pagecheck'] = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
// set the section var if it hasn't already been set by one of the content pages
if(isset($_SESSION['sectNum'])!= "undefined")
{
$_SESSION['sectNum'] = "0";
}
function getSection() .....
Additionally, are there any potential security threats that should be tackled (bearing in mind that I don't want to use cookies, I'm not against this either but decided if they are switched of it may become an issue, and I'm not going to be handling any sensitive information). I really don't want to use Iframes due to any javascript switching off related problems (yes there is a javascript testing function included in my full code!).

I have two AJAX commands. One creates a list of items, the next highlights a specific item on that list. I don't want to combine these two commands because I often use them separately in different functions. However, the first command - the one that lists the items in an innerHTML - must complete before the second command is called. I used to just set a few seconds (as you'll see below) before the next command was called, but now the list is growing longer, and it no longer works. Is there some kind of command to only execute it when the previous command is ready, like "onReadyState"? Code:

I have a shopping cart with a quantity field. I also have an update button that updates the totals. Myquestion is how can I use jQuery to check the quantity field when it loses focus, to check the value against the database and the Instock field. If gt then display a tooltip (or something) and not allow the form to be submitted. The problem is the field is called sel_qty for each product.

Our client has asked that we things up so that the user must fill out
a short form with some basic information if they want to access a
number of PDFs on their website, once per session (please don't ask me
why). Submitting the form sets a session cookie.
Specifically, if the user clicks on "example.pdf," I'd like to have
one of two things happen:
1) If the session cookie is set, the PDF is accessed transparently.
2) If the session cookie is not set, the user is sent to the info
form, and on submission is either (a) passed through to the PDF they
clicked the link for, or (b)at least is sent back to the original page
where the link resides so they can select it again. My initial thought
for the latter case was to have the form open in a new window, then
have a close button on the subsequent confirmation page so the
original page is still open in the background.

I'd like to be able to detect whether the browser is receiving an HTTP
status 302 redirect when handling the response to an Ajax call. I can
see the 302 status code clearly with LiveHTTPHeaders in Firefox, but
every time the XmlHttpRequest onreadystatechange handler is called, the
status property is éU'. It seems like the 302 is being handled by the
browser somewhere upstream of my JavaScript.
(I know that this has been asked once before -- that I've found -- in
this group, but it seems like the only response misunderstood the
question.)

The general framework is a simple user login function. The user name is selected and a password entered as usual. The function grabs the element values and passes them to a php page that queries the database. An AJAX call returns the password to the function and then I want the innerHTML to be a choice of two web pages, depending on success or failure of validation. There are existing AJAX functions available on the internet but they are overly complicated for what I think should be a simple, quick to load function.
Where I am stuck is that the standard procedure to make an AJAX call is the browser window event. How do you make the call from within the function? I have tried creating two new variables, "success" and "again" to replace xmlhttp, but still stumble on the event to assign a value. I left the blank password protection (if statement) with that variable to demonstrate what I mean.
I've put in my code below, which is in development and successfully alters the innerHTML text depending on user input but I can't figure out how to insert the relevant php page. I have '// out' the testing bits, but left them for info. (I have tried full 'scripting' as the innerHTML, but it's messy.)

I have a simple ajax request that is supposed to (after a short timeout) redirect the page to the URL that the server sends back but it just wont work. It does work without the setTimeOut() function however.
var http = false;
if(navigator.appName == "Microsoft Internet Explorer") {
http = new ActiveXObject("Microsoft.XMLHTTP");
} else {
http = new XMLHttpRequest();
}
function go() {
var u = "http://site.com/";
http.open("GET", "go.php?" + "u=" + u, true);
http.onreadystatechange=function() {
if(http.readyState == 4) {
var redirURL = http.responseText;
setTimeout("window.location.href = redirURL;" , 2000);
} }
http.send(null);
}

I'm new to JS / Ajax; I've been trying to do an Ajax call to my
Webservice ( I'm using C# for code-behind). I'm not using any of the
libraries available. I am sending my CustID to the webservice and the
webservice returns a Dataset that contains various customer details
taken from database. I have tested that the Webservice itself works.
But my ajax call is not working.
My ajax call is something like:

I'm having a problem where a button no longer triggers an event after I changed it through an AJAX call.Problem is, once AJAX has updated the DIV, the contents in RAM is different from what I see when I check the page source (CTRL-U in FireFox/Chrome).What tools are there to display the current contents of the DOM? I generally prefer to use Chrome/Iron, but if there are better tools for Firefox, I'm also interested.

I'm admittedly a novice when it comes to AJAX. I can get stuff to work, typically, but really have no idea what's going on. I copied the original code from another source.
Now, something a bit more complicated is coming up and I can't get it to work.
Here's the script I'm using to start; the one that I typically use that works fine code...

I wish to make an AJAX call to a script on a different domain - realise this is a security problem, but is this at all possible?
My client is embedding html web pages into his ebay listings, and he wants to centrally update the product information. Maybe there is a different / better way to go about this?

This code updates a feedback box every 5 seconds. Web page:
<body onload="fback();setInterval('fback()',5000);">(declared firstly so that you don't end up with a blank space for 5 seconds when the page loads.) This calls an XMLHttp request to feedback.php.
xmlhttp_fb.open("GET","feedback.php",true); The php page queries a table and returns one item from about 360 records by randomly choosing a UniqueID between 1 and the last row. I deliberately chose this because it's quicker than querying them all once and working through an array.
[Code]...
Enough code to give you the idea I hope. $max is the last row of the feedback table. (Found by ORDER DESC)
This works great in Firefox and Chrome but not IE7 or 8. Really can't think why because there are no setInterval issues that I know of.

Not sure if I posted this in the right area since its a Javascript/PHP related problem.I have no clue how to check if a user didn't leave the site.Ofcourse you can use the Onunload() or Beforeunonload() function.But some browsers like Opera and Safari and who know what other browsers don't support it.Is there any other alternative?Like expecting server side each X seconds a AJAX request from the user?If the user doesn't send a request, the user has left.

Goal 1: display errors above the form on same page
Goal 2: direct users to a new thankyou page when form is submitted.
The form uses ajax. I am able to get it to work with the error messages displaying correctly but as is, the thankyou message also displays in the same spot and the form is left filled out. I need it to direct to a new page I designed for the purpose.

type: 'GET',
url: 'myURL',
success: function(data)
[Code]....
Is it possible to get two have two ajax calls , one dependent on the other?
