All Ajax libraries I've read use encodeURIComponent() on the name-value pairs extracted from forms before POST ing the result to the server with and xmlhttprequest. I can understand why this encoding is required in the case of a GET request and the form data is attached as a URI query string; however, why is the encoding necessary for POST requests?

View 1 Replies View RelatedI am analyzing header tags for submitting forms online in order to better understand how htmlhttp forms work- signing in to gmail, yahoo mail, and amazon, using the network tab of google developer tools, to view the http headers of requests and responses, and learn where they come from. I am seeing very peculiar behavior in my browser's (chrome)request headers when signing into amazon. The form data, always has the following two header names appended to the second and third to last places of the form data query: x=(some random number), and y=(some random number).
There are no input tags getting dynamically generated,since when i tell google chrome to break on all subtree modifications, the site still sends off the post with the added parameters before anything gets modified, BEFORE crashing. There also is NO ajax call which is causing dynamically added data to be appended to the form post.My question is this: is there any way, using javascript, to instruct a browser, to append data as data, to a form post, WITHOUT the use of dynamically appended input elements, or ajax?
I have a form that submits a POST request when data is submitted.
A Servlet then processes this POST request and a JavaBean is used to make some calculations. The HTML response is not generated within the Servlet but instead I forward the request to a JSP to generate the response. - This all works fine.
However, I am stupidly suck trying to validate the form on the client side with a Javascript function before the form is submitted.
Here is my index.jps:
Regardless of whether incorrect input is given, the data is still POSTed to the server and calculated on or a Server Side error is given.
Am I correct in calling the function onclick?
The validation essentially needs to be so that:
- Student field contains a string
- Score1, Score2, Score3 and Score 4 contain a number between 0 and 100
I'm trying to send data to my server using xmlhttp POST. The data being
sent is actually an HTML page that is built with javascript in the
browser. The HTML code contains a small javascript function in the
<HEAD> section. I applied encodeURIComponent to the data prior to
sending it but anything between the <script> </script> tags does not
get sent. The tramsmitted data is cought by a Perl script on the
server, it handles the input as normal FORM data and writes the html
data sent to a file (with the javascript function missing). Maybe I
need to do something different related to encoding the chars for an
HTML comment (?) ...
My requirement is like this,we have 2 text fields called name
and number and one button named submit.when ever we click the submit
button then we need to store the page information(form values) into our
database and need to post this form values to some other site
(eg:action="google.com/signup.aspx"). How to do this in asp.net please
send me the code.
Is there a way to make a javascript post request to MyPage.aspx,
set a variable on MyPage.aspx, then do a javascript redirect to
MyPage.aspx and still sustain the value of the variable posted to the
page in the first place? As of now i'm successfully posting to my aspx
page, and successfully redirecting as well, but i have been
unsuccessful with sustaining that variable. I've tried using ViewState
as well as Session, neither seem to work exactly how i'd like.
Essencially, I'm trying to send a post request as well as redirect to
the same page Code:
I tried POSTing from XMLHttpRequest, i can get the XML right on server
but responseXML from server is coming null. I can see the XML right in
responseText. but responseXML is null. responseText to DOM conversion
also fails while the XML in responseText seems valid ..
-- here is the javascript code for sending ---
Currently transitioning from a shared host to a dedicated server. The
same code that works on the old server is not working on the dedicated
server. It is a simple AJAX request like:
<code>
function createXMLHttpRequest() {
if (window.ActiveXObject) {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}
else if (window.XMLHttpRequest) {
xmlHttp = new XMLHttpRequest();
}
}
function doRequestUsingPOST() {
createXMLHttpRequest();
var queryString = "response.php?";
queryString = queryString + createQueryString() ;
xmlHttp.onreadystatechange = handleStateChange;
xmlHttp.open("POST", queryString, true);
xmlHttp.send(null);
}
</code>
With the code as is above, the requests works fine in IE. With Firefox
it throws a 403 on the page. A call to the response.php page with
parameters runs correctly outside of AJAX. Changing all POST requests
to GET resolves the issue, but I would prefer not to have to change
ALL POST requests to GET requests.
Does anyone know of a setting on the new server that can cause FireFox
(1.5.x and 2.0.x) to return a 403 with an AJAX post call?
I don't know the reason of getting the message as 'undefined' in alert dialog box, whenever I do the post request to servlets from jquery after clicking login button.Here's the code which's making me bugged:
$.post("Check.do", $('#form').serialize(),
function(data){
alert(data.message); //displaying undefined
});
}
the request is passing to servlets(which is mapped to Check.do URL), and in doPost method in servlets I'm just doing: response().getWriter().write("Hello");May I know the what's the reason of getting error in above code, and how can I sort this problem out?
I am trying to send request using ajax with some japanese text.
As any of you know XMLHttpRequest is send with utf-8.
I was hoping there is a way to send with different encoding like
var parameters = "metadata=" +
encodeURI(document.getElementById("metadata").value);
http_request.onreadystatechange = metadataUpdate;
http_request.open( 'POST', "/servlet/SendJapText", true );
http_request.setRequestHeader( "Content-type",
"application/x-www-form-urlencoded;charset=Shift-JIS" );
http_request.send( parameters );
I was guessing if it was possible, using jQuery, to have a link that, when clicked, opens the relative url and sends to it a post request. I'm trying to do this with the $.post function, but i found the problem that the request is sent, but the page isn't opened.
This is my code:
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>

I have some trouble with my app. User enters his login&pass, they are being checked on server using ajax, and if they're ok, i wanna open new page, which'll set cookies and session vars, but i have an universal script, and I need request something like universalScript?mode=login (mode is GET) and some POST parameters such as login and pass, besides it must be new page, not ajax, Some ideas?

I am writing a small data entry screen that will post the form data to a page and return a message. But i cannot get the Success or Error functions working properly.
Here's the code where strData is the posted querystring of:
I'm not sure whether it should be in a form and using the onsubmit or click of a button.
I have a very simple javascript codes with a following lines inside:
............................
var str = "";
.. . . . . . . . . .
str = String(new Date()); // #1
str += fobj.elements[i].name + "=" + fobj.elements[i].value +
"&"; // #2
str += fobj.elements[i].name + "=" +
encodeURIComponent(fobj.elements[i].value) + "&"; // #3
str = 'Test' // #4
............................
1) If I commented out the line #3 everything works OK.
2) If I leave this line in my script, lines #1 and #2 have no
problems, but the line #3 failed (without any trace) and I never reach
the line #4.
It seems the global function "encodeURIComponent()" is missing (by the
way, the global functions "String()" and "Date()" are not missing and
they returns a correct value).
How I can fix this problem?
I wrote a form with a little DOM/AJAX to submit the form data. The page is being used in google ad campaign, so after a user fills in the form, a google script is run to count conversions.
I am having trouble getting the script to work properly. Since I am not reloading a page, I am including the file dynamically the DOM WAY. Below is a snippet of the code. The code is part of a function that runs when the readyState == 4. Code:
I really don't understand why I am getting this error (parsererror TypeError: data is null [object XMLHttpRequest]) after making the following AJAX request:
var base_url = $('span#base_url').text();
var model_url = "index.php/status/get_xml/"
$.ajax({
type: "POST",
[Code].....
So I am wondering why the .ajax function has an error, and yet the XML is being returned?
i need to post data from a form to a page on another domain, without leaving the current page.I am using ASP as a server language.
View 9 Replies View RelatedMy prob is that the huge amount of data (15MB of XML) that is loaded by an AJAX call, literally locks the browser while loading it into the DOM. Does any of you know if there is a way to prevent that. Btw - As you see I use jQuery and the ajaxManager plugin.

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...
View 14 Replies View RelatedI am doing a JSON request to get data back from a PHP file. On the return of that data, I am using a for loop to go through the data and post it up using JS. Here is my code:
for (var x = 0; x < data.length; x++) {
//create a container for each comment
var div = $("<div>").addClass("entry round").appendTo("#characters");
//add author name and comment to container
$("<div>").addClass("details").appendTo(div);
$("<span>").addClass("main-armory button").appendTo("div.details");
}
Now, what is happening, because there is 10 entries being posted, my JS is looking at the class that is being put together (main-armory button) and making it so that class appends every run through. So, I want one entry for main-armory button and I am getting this:
<div class="details"><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span></div>
And then, when it goes down to the next entry, it has 9 spans, and then the next entry has 8 spans, and it continues all the way down. What is going on here that I am missing? I know that I am not clearing a variable properly or something is wrong within my loop.
I am trying to make an ajax POST request but its not working. Code below:
var _HOMEDIR = "http://localhost/personal/index.php/home/";
