My JavaScript is trying to POST data to a CGI script (Perl) using
XMLHttpRequest. My CGI server gets different data from IE than Mozilla
Firefox.
// For Mozilla, req = new XMLHttpRequest();
// For IE req = new ActiveXObject("Microsoft.XMLHTTP");
req.onreadystatechange = requestHandler ; // function to handle async
response
req.open('POST', myURL, true); // use POST
req.send('foo=11&bar=22') ;
A Perl CGI script prints the parameters passed to it.
$q = new CGI ;
foreach my $param ($q->param) {
print "$param: " . $q->param($param) . "
" ;
}
The data received by the CGI script is inconsistent, depending if the client
is IE or Mozilla (Firefox)
Server result from IE client:
foo: 11
bar: 22
Server result from Mozilla Firefox client:
POSTDATA: foo=11&bar=22
It seems that the POST data IE sends is more correct than the Mozilla data.
Is there another way to send the data in Mozilla so the CGI script will give
the same results. I could easily adjust the CGI script, but I think the
problem is at the client.
I have a form in a webpage that I want to submit and get the result back without reloading the page.
I've seen many times ppl using text/x-www-form-urlencode but I was wondering if it was possible somehow to submit the form element directly so I wouldn't have to process the form to put it in a string.
I am having a problem using the XMLHTTPRequest, is something wrong in my code? How do you post data, I tried this but the PHP does not receibe any posted information, like if nothing was sended, i try this with Firefox 1.0.6 on Linux Fedora Core 3, thanks in advance for any ideas...., could it be some kind of firefox implementation bug? Code:
I am playing with the XMLHTTPRequest method to perform client/server transactions. I have it set up right now so that when readyState is 4, it takes the XML and processes it. This works great until there is alot of data. In that case, the user will have to wait for the data to come back which may take a minute or so.
I don't want the user to have to wait. Is it possible for javascript to periodically (while still receiving more data) stop and display what it has received thus far? I guess this would be considered a type of streaming.
In mozilla/firefox, I have read that I can use readyState 3 to run my callback function every 4096 bytes. I can then take those 4K, parse them, and then continue on. However I have also read that IE cannot do this. Since I need this to work in IE, is there a workaround?
I'm working with a pretty large XML file, but I really only need to display a few things that requires quite a few transforms. I already limited to the transforms to the data i need to use, but I'd like to speed things up by loading only the data I need.
I need to mention that this is for a local application that sometimes will lookup updates on a server, but mostly, it is for local use (offline)
I can use xmlHTTPrequest for both local or server data access. That seems to work fine. Now I would like to be able to load only the data I need.
I hear the Google suggest tool bar uses xmlHTTPrequest to look up a list of known queries, so I am hoping they lookup "only" the necessary data as one types. It's kinda what I want to do, but I'm not sure how that would work, since the "url" parameter should be a destination file name.
I am having trouble populating elements from the following Yahoo RSS feed: [URL] I need to show the current weather conditions when a button is clicked. Here is what I have so far.
[Code].....
I need to populate the <h1> and two <p> elements. I know that the copyWeatherData() and getWeatherData() functions are not coded properly.
I'm reading the content of a local binary file with the method mentioned here: [URL]
Then I'm getting the data as a string where each character represents the binary value. I have successfully sent that string with Mozilla's XmlHttpRequest's sendAsBinary method, but IE 7's version doesn't have that method...
Using the send method almost works, the only problem is that binary content can be represented as the asciicode 0. This means that the string read by sent is cut off as soon as it is encountered. That means that the part before the first NULL character (asciicode = 0) is successfully sent to the server.
The solution I have made right now is to increment each character's asciicode on the client side by one and decrement them on the server before converting the character to the binary representation. The downside with this is that the size of the data sent between the client and server gets larger than the original filesize. Ex: 8kb file grows to ~12kb.
I wonder if i can make the variable data which is [data] in jQuery.post( url, [data], [callback], [type] ) dynamic. for instance, this is the form i want to send,
for streaming the data by keeping the connection open. At client side, i am having the XMhttprequest object (i.e ActiveX object of IE). When the data comes, onreadystatechange method get callback on state 3 but it doesn't allow me to read the data from the object. It says 'The data
necessary to complete this operation is not yet available'. Is it possible to read the streaming data from the XMLHttprequest object in IE?
I know Mozilla supports to read the data, when the ready state is 3. In
Internet Explorer, how we can use the XMLhttp Active object to read the
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 am trying to read data from server using AJAX XMLHttpRequest.responseText.In received data, there are lot of similar type of characters which has tge value of FFFFFD (65533). I think, all characters which has the value above 127 are converted to default character.
How do you transform a data Island and/or XML file with an XSLT in anything besides Explorer. Any kind of semi-well written resource would mean the world to me (or better yet an example). I'd be a dangerous man if I knew how to.
I am making a visual database for our company to give to our sister company in another state so they can have name, phone, email, and a picture. All of this information is in XML outside of the HTML document. I have provided the HTML and XML below. It works perfectly with Mozilla, but all Internet Explorer displays nothing from the XML. Please tell me what I'm doing wrong because I am completely stumped
Code: $("#save_photos_all_continue").click(function() { event.preventDefault(); var $black_white_all = $("#black_white_all").is(':checked'); var $color_all = $("#color_all").is(':checked'); var $other_all = $("#other_all").is(':checked'); [Code]...
In Google Chrome it works fine but in Mozilla/5.0 it actually goes to the save_edits page instead of just using the post and staying on the original page.
Is there a way to retrieve POST data submitted from a form using Javascript? I know I can use PHP, but for lengthy reasons I cannot so I only have JS to work with.
can anybody help me in writing a javascript function which opens a popup window with the target URL when the link "POST Request" is clicked..
Points to note:
The HTML DOESNT and SHOULDNT HAVE A FORM TAG. The URL data should be sent as POST and not GET..i.e the search parameters should not be showin in the address bar when the page is opened.
I'm a total JS/jQuery newbie, and I'm having a problem using jQuery's load() to POST data to a remote PHP script and rewrite a DIV with whatever the server sent back.
Using a proxy in between, I can see that the JS script isn't sending anything, so I guess there's something wrong in the JS code I send to the browser [code]...
i want to send data(inputdata) using jQuery to a php script, the displaying the returned data(returndata) in a div but what happened that the (inputdata) don't get send this is my code it will explain it self better: HTMLfile.HTML
<HTML> <head> <script type="text/javascript" src="jquery.js"></script> <SCRIPT language="JavaScript"> function swapContent(inputdata){ [Code]...
I have some radio buttons and do a jquery post on click. Something like this: $.post("method", { value: value }, function(data) { alert(data); }); the value data does have the correct result, but my problem is the page doesn't refresh to that data.
I have a lot of tables and to get it to post some of the data into a form.
So say i have a location and a start date and end date, and when i select a radio and click submit the location and dates get put into the corresponding field in the form.
However i have a lot of tables and a lot of different options but want it to go to only one form. this form can be on a seperate page, but was wondering if its possible to get the form to appear on the same page, underneath the table.
