I 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.
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 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 am trying to pass an argument to a function to process server responses. My original line of code looked like this: [url]
This works well enough as is, but I am trying to pass arguments to the function, and everything I am reading says to contruct the code like this: [url]
Every example I have come across uses this same approach, but I keep getting the error "Expected ';'" pointing to this line and then the code fails to execute. I just cannot see where there is anything missing, and it looks pretty much identical to my examples.
I have also tried replacing the call to the function with the actual code in long-form, and the result is the same.
I am developing a fairly complicated application with a lot of JavaScript and making use of JQuery. The application repeatedly makes simultaneous GET requests.
I am looking for a way of assigning a unique token to each request when it is made, so that I can store information about that request and cache the request / response combo, when using $.get() (or potentially $.ajax() if required for the extra functionality).
So far I have not had any joy and after a while googling this am none the wiser. I have used similar functionality in Flex 3 with the AsyncToken object which can maintain data between HTTP request / response.
Now that http://username:password@site.com no longer is an accepted syntax in IE, I suddenly have a case in a project I'm working on. The easiest(?) solution would now be that there was some Javascript function that could pass the username and password or in som other way automate the login process on a given site.
Thing is I have a server-generated HTML page that I want to make the client redirect to a password protected site. (IIS Windows authentication).
I am trying integrate an upload system from YouSendIt.com in to my companies forms. The code they give for integration is basically an iframe with a coded URL set for the source. Their server sends a postback using HTTP Post method but I am not sure how to access the data that is sent back. I do not need to display it but I need to use it for validation purposes in the rest of my form. The Iframe code is as such:
I have written an Ajax application which can send http HEAD requests and receive the header response from server.
Now I want to show the different values in formatted manner. However, there seems be no character or expression which I can use to split the HEAD response for string processing.
Here is a sample of server response:
Mime-Version: 1.0 Date: Thu, 08 Feb 2007 03:51:13 GMT Server: Apache/ 2.0.1a Content-Type: text/html; charset=utf-8 Content-Length: 69 Connection: close
If you have any information regarding this please do let me know.
I'm trying to write a script that will be loaded from one server into a website on another server. This script is trying to talk (ajax) to the server that it comes from but I'm getting "Access Denied" errors. I'm well aware that cross-domain calls are not allowed for security reasons so my question is how does Google Analytics work because essentially thats what I'm trying to accomplish. I can embed a Google Analytics script into my website and it'll gather data and send it back to Google.
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.
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...
Can anyone redirect to any online tutorials, articles, code of how to upload a file using HTTP PUT method and JavaScript or VBScript to a server running Apache 2.0 that uses CGI + PERL.
How to create configuration entries in httpd.conf for supporting HTTP PUT method.
How to code with AJAX to post uploaded file content to the server using PUT method ?
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 have managed to succesfully post the data to the php page... (i can see using firebug that it IS being sent) but i get a message Quote: Apache HTTP Server has encountered a problem and needs to close and the response is empty... what am i doing wrong?is possibly something to do with the space in the value of the options?
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.
Have been trying to figure this one out for some time, but still can not get this AJAX script to work with Internet Explorer. It works with all other browsers.
I am trying to get my site [URL] to run consistently on all browsers. I'm using AJAX code that works great on Safari and IE8, but only work intermittently on Firefox and Chrome.
I posted this problem in the old mailing list, but I thought Id try here with a larger set of eyes.
My issue seems to concern webkit browsers. I am sending information from a form with a jQuery click function. I am loading the response from one form that is a DIV called rightContent to the same DIV and passing the
OK, never seen anything like this before. I have this AJAX shopping cart I am developing where they add a product and the side bar of the site updates what's in the cart automatically. Works perfect in all browsers except IE (6 and 7).In IE it works the first time you add a product then after that the sidebar does not update AND there are no JavaScript errors. The cart is actually updated because when you refresh the page all the items you added are there.... got me scratching my head to say the least.Here's the scripts that run it (a little messy because I am still tinkering with it:
