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?
View 2 Repliessynchronous vs asynchronous $.post
may i know the difference?
I'm trying to get a return boolean or something I could use to then do another asynchronous request have my first has completely finished.
I'm messing around with Javascript on this basic PHP blog I built and I have a table of articles and one of the table columns is published/unpublished. I'm trying to have when they click the icon it will connect to MySQL, update the current row with new publish value (opposite of current) then refresh the div id element that the publish/unpublish icon is in to reveal the new status. I built a class for my javascript requests so most values are stored in global properties.
I think what I'm coming across is when I click the icon it updates the table but before that onreadystatechange can hit 4 my request for the new content is going through so the request url I'm using as well as the return div id for the responseText are getting mixed up between trying to do a sql update, loading the responseText in "message" then trying to sql query for the new results and loading that responseText in "content".
Something like..
url = "?table=articles&value=1&id=2";
http.onreadystatechange = this.stateChange;
http.open("GET" , url , true)

I cannot get ajaxSend [URL] to properly modify the parameters to include a random timestamp and, for IE's sake, a _method=value pair. I have:
$
(
document
).
ajaxSend
[Code]....
how can I make sure that what gets sent across the wire is the value I set settings.data to in my ajaxSend() method?
i m trying to implement captcha in my site.i m using recaptcha. To check the captcha i need to request url like: [URL] and then i need to check response from url if it is true or false i dont know how to request response from url
View 2 Replies View RelatedI have two forms: register and contact, with action attribute that looks like this:
REGISTER.PHP AND CONTACT.PHP FORMS
<form id="myform" action="submit.php?url=register">

I would like the jquery ajax function to redirect to the above url parameters so that the forms can get processed in their individual functions.

Im trying to use jquery to try to do what the image shows: Its for a website made for iphone so im trying to add the slide effect. It all seems a little complicated, but ill explain: 1-The user clicks a link
2-A loading message (or image) appears Meanwhile, the new page loads on a hidden side (its a FULL page, not just a div)

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 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>

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:
For some reason I can't seem to print out the post parameters sent through out my login php script using ajax.. according to ajax (*responseText) the parameters are getting passed.. so.. it got me there..
javascript 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?
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 10 Replies View RelatedHow can I do a post request to another page from javascript ? Actually I only need to pass data to another script through a post request.
View 1 Replies View RelatedAnyone loading a bunch of CSS or Javascript via <link> tags on a web page knows about "blocking": where the browser stops the loading of the page because it has to go fetch (and read/parse) an external file. If you have a lot of these, or even if you don't and the user has a slow connection, you have a slow page. Users hateses teh slow pages, hatses them.
At the 2010 Fronteers Conference, Stoyan Stefanov gave a talk on Progressive Downloads and Rendering, where he listed some tricks to get around blocking by Javascript or other external files to make page load speed up. One trick was adding a <script> tag in the body (near the bottom, so after the important stuff has loaded) which adds a <script> tag to the <head> dynamically and runs it. While that file is being fetched, the rest of the page can continue to load. This is a bit asynchronous, isn't it (similar to web pages still loading content while also fetching images)?
As a follow-up to his Higher Order Javascript article (see SitePoint thread about it), Piers Cawley has gone further with Asynchronous Streams, where he uses jQuery (as an example) to load external files asynchronously to avoid blocking of the HTML document loading. In my web development career I haven't worried about blocking, but plenty of folks around here are loading ginormous files, and lots of them, for large sites. As developers, what do you do to get around slow page loads? Have you done anything like this asynchronous calling of the external files?
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 have this code w/c makes a post request.
Code:
// start ajax code
var http_request = false;
function makePOSTRequest(url, parameters) {
http_request = false;

I 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 need to capture input from a form in the run time and send those values as URL parameters using HTML POST.
I am using:
Here searchText and searchFilter are the input values. When I run the app, I don't see the values but I see "frm.searchText.value" and "frm.searchFilter.value" getting passed as parameters.
What is the right way to apply javascript here?
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 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.
