where someData is a vanilla object of key/value pairs, submissionUrl is a valid URL and ajaxSuccess/ajaxError are both functions.Using jQuery 1.5.1, the GET request is delivered to the server without the data. Using jQuery 1.4.4, the request contains the data.Has something changed in the way I should be assigning data to an ajax request in 1.5.1? The docs don't seem to suggest I'm doing anything incorrectly.
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.
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 found this formwizard script example online but I don't know how to use the data with php for emailing and saving to database for example.The script attaches the result to <p id="data"></p> like this
I am trying to build a table from backend data and then perform a filter on it using the picnet table filter. After much messing about I have discovered that the problem lies with the table data returned from the server. As a test, all I want to do is get jQuery to make an alert when a table cell is clicked. I added a hard coded table cell at the beginning of the table and when I clicked on it, the alert appeared. However, clicking on any other cell had no effect.
I am using .ajax() to access cross-domain data using JSONP. Because I need to be able to cache the data I want to use a static name for thejsonpCallback function, so I have set the jsonpCallback option in the .ajax() request. However that appears to requires a global function whereas the auto generated function didn't (well maybe it did but that was all hidden from me).
I definitely need to be able to cache the results. Ideally I wouldn't have a global function handling the data. Is there another way to do this? If not what is the best practice way to go about using a global function these days and how do I provide it with the context of the object/module it was called from - which is where the data is needed?
I built a pretty simple Ajax request which needs to send some data to the server and put the resulting HTML in a div. Unforunately, I need to POST the data. I used .post() and it worked fine ... *on Chrome and Opera!* ... on Firefox no data gets posted even though firebug shows the data in it's console. I ended up building the longest possible request, just to try all the options. No luck. As soon as I POST anything, Firefox won't receive the data. If this was a Firefox issue, wouldn't I read about it everywhere? What's wrong?
Wantto import data from excel to SQL server from a web page, but wonder whether it is possible to do it without uploading the excel file from client's machine to server first.
You can use JQuery's data method (e.g. $('#MyID').data('MyVar', 'MyValue');) to easily store/retrieve information.
However, I was wondering if it is possible for my PHP generated page to add HTML tags that initialize the JQuery's data method variables. Regularly, I want server side variables to be accessible client side. It would be very helpful if I could initialize data method variables during PHP page generation.
If this is not possible, are there any suggestions on how to efficiently communicate server side variables to client side?
I am still new to jQuery and I am trying to figure something out. I have this code:
[Code]...
This is working fine on itself. What is does is when I click a link it loads data into the following div. When done loading it slides out. But I want to change the appearance of the slide. I have tried to do that like this: $(this).show("slide", { direction: "down" }, 1000); But this doesn't work. When I check firebug it says the following: o.easing[this.options.easing || (o.easing.swing ? "swing" : "linear")] is not a function
I know about the same-origin policy and that one of the only ways to load data from a cross-domain is to load it as JSON. However, all I am trying to do is access data from a server on another port (which I believe the browser still treats as cross-domain). I need to do this because the server my application is on is a map server and the other server (Apache) is the only one that can handle php scripts. I have also tried out the plug-in from [URL] and while it works when I do $('#phpContent').load('http://www.google.com'); it doesn't work when I try $('#phpContent').load('http://localhost:80/mapScripts/getFiles.php'); I have also tried$.get('http://localhost:80/mapScripts/getFiles.php', function(data) { $('#phpContent').html(data); });
So here I am breaking my brain and do not know what else to attempt.
I have a table that gets served off to a 3rd party site. Each row has "track" and "hide" checkboxes ... I need to save/update these settings as the user updates their settings so I can call them back later on future visits.
(cookies are not an option... because that is too easily lost and there could be thousands of settings over time)
So, I am leaning toward a AJAX POST using Jquery. Rather than submit on every change... I would like to store the settings in JavaScript and then batch submit every 30 seconds or on page unload. I have most if this working... it is the saving of the data and then batch submission code that I am after.
Let me give you the use case and a scenario:
Table with 100 rows and each row has "track" and "hide". Each row may be associated with one "subject" and multiple rows may have the same subject ... so when you track or hide... it tracks multiple rows (highlights, checks their boxes, and grabs the subject from a row field) OR it "hides" multiple rows based on their subject.
All that is working. (Yes!)
Now, because they could be clicking quickly through... they might track then "untrack" the same subject or hide then "unhide" the same subject all within a very short period of time.
I don't want all those AJAX calls!
So, I need some sort of data storage for the "subjects" that puts them in "track" and "hide" datasets ... removes them out if undone ... and occasionally submits whatever the queued up actions are (if any).
Also, there may be settings grabbed on page load that need undone (the track and hide setting grabbed from the DB that pre-dated that visit) ... so it may not as simple as removing from a data set... there should be an explicit "untrack" & "unhide" submission in those cases to update the DB.
What i want to do is that this function post data to the server (ASP) and the server will response with 'OK' My question is how can i send data clientside from Javascript to the server ? (navigate ? with url ?)
and check the returned data in the same function ?
function ShowData(TxtArt) { alert(TxtArt + ' : ' + parent.frames.Bottom.TxtUsrName.value + ' - ' + parent.frames.Bottom.TxtRemarque.value); // testing purpose // post the data to the server. ex .. myURL.asp?userID=1000&Art=ART1201 // fetch the data from the server. to verify if the 'OK' is recieved -> the server will response with 'OK' // if 'ok' -> i will update clientside an frame (ex. contents of shoppingbasket) }
I have a webpage which handle a time-consuming backend processing on the server side. I am hoping to use ajax and display the back-end processing process on the web-front(i.e. in a DIV). .ajaxStart and .ajaxStop sound to be OK if I want to display some fixed content. Is it possible that I grab partial server-side resultset and update a DIV at the front-end without having to wait for the server-side to finish all of the processing.
Below is my sample code which does NOT work for my purpose.
---- <span id="processing_status" class="blink"></span> <div id="processing_log" style="display:none"></div> <script type="text/javascript"> /* This is OK, but I want to display server-side processing records */
I am getting following data from the server Collapse: < allstudents> < student> < rollno>8001< /rollno> < name>AAAA< /name> < /student> < student> < rollno>8002< /rollno> < name>BBBB< /name> < /student> < /allstudents>
I have html page containing div with id 'dvtbl' now I want to generate the following table inside of dvtbl Collapse < table> < tr> < td>< input type=" checkbox" name=" cbRoll" value=" 8001" id=" cbRoll8001" /> < /td> < td>AAAA< /td> < /tr> < tr> < td>< input type=" checkbox" name=" cbRoll" value=" 8002" id=" cbRoll8002" /> < /td> < td>BBBB< /td> < /tr> < /table> h How do I do it using jquery? In the callback function of $.ajax?
i have a series of <select> fields. The first one, via ajax(), generates a 2nd one, based on the first ones' data with the .change() method. there is then a 3rd <select> - who's data will depend on choice of the second one although step 1 works, and i can generate the 2nd one, i still can't generate the 3rd one.
when i test the script on its own, both the 2nd and 3rd <select> fields are fine - but not via the ajax, which leads me to believe that the .change() from the 2nd one, isnt triggering the ajax call - its not being picked up (even the 'hello' alert isnt working).
Read the first reply below first/instead, it's probably more helpful than this one
There's a lot of talk about AJAX these days and it seems to me it's turning into a hammer for a lot of problems that aren't really nails. If you want your pages to call home but don't want to have to deal with XML parsing and extremely spotty browser support, here's a very simple way to effect communication from Javascript to the server. The server can only (easily) communicate back on the next page hit with this method, but as a one way conduit from client to server post page rendering it can hardly be beat.
I've set it up with a really simple case that keeps track of the total time each user spends looking at a page in ten second increments. I have, for clarity (I hope) stuck it all in one PHP file, but it'll work the same with any server side language:
<?php // this block isn't really too well coded or useful, it's intended more as a simple proof of concept if (isset($_GET['ip']) && ip2long($_GET['ip']) !== false) { // if there's a GET variable (this.php?ip=something) and it appears to be a valid ip... $fname = sha1($_GET['ip']) . '.time' if (file_exists($fname) && strpos(($pre = file_get_contents($fname)), '=')) { // if we have a file and it looks like it might be in the right format, increment the value contained therein list($ip, $time) = explode('=', $pre); file_put_contents($fname, $ip . '=' . ($time + 10)); } else { // else just write it in and hope for the best file_put_contents($fname, $_GET['ip'] . '=10'); } /* //actually returning an image here can help get the loading message out of browser's status bars
header('Content-type: image/gif'); fpassthru('small.gif'); */ } else { ?> <html> <body onload="javascript:setTimeout('serverTick();', 10000);"> <script language="javascript"> var ip = '<?php echo $_SERVER['REMOTE_ADDR']; ?>' // give the javascript an ip or a hash or something to pass back that will be reasonably unique
function serverTick() { setTimeout('serverTick();', 10000); // call this function again in 10 seconds var notshown = new Image(); notshown.src = '<?php echo $_SERVER['PHP_SELF']; ?>?ip=' + ip; // calls this file in attempt to preload an image, instead triggering the above block of PHP } </script> </body> </html> <?php } ?>
This will work in far more browsers than AJAX will, and it's not subject to any domain restriction, it can post to another server without generating security exceptions. It may be possible to get data back in the body of the image and it's definitely possible to get data back coded as image dimensions, if you want to push this method a little further.
how Google Analytics or Google Adsense lets you copy and paste javascript to your site and you can load data/track visitors/etc. Well, I want to do the same thing for my customers, on their domains, where they load dynamic prices on my server (long story). Is $getJSON the best solution in this day and age? I would prefer to not force them to use frames and I am not worried (nor are they, for reasons I wont' get into) about users who don't use javascript.
In short, our site processes payments for them and there is a unique feature that offers dynamic prices. So if they have javascript code with an order button image, I want them to hit my server and have their javascript code read my server, find the updated price, and display it to their user. note they will be using .html pages, not php, and they are not programmers and I want to simplify it.
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.
Problem is, I can't access dataValues at the server side once I assign this same URL to the iframe.Is there any other way to POST JSON value through form submission without ajax? or any other way out, I am trying to download file that is based on some parameters and isn't a direct download link.
