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.
The code is supposed to generate this: PS: This is generated by a PHP Function that the Ajax Load Method Calls.
[Code]...
I've been noticing a lot of problems when loading these stuff, Sometimes I have to remake the HTML Tags because its not showing anything. Is there any option? I want it to load EXACTLY how it is, I don't know if this is some kind of protection for bad code, but if it is I would like to disable. But also, this code is really clean. no problem, I don't know.
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) }
The assignment was supposed to be done in PHP. But I want to know if there is a better way either way. Like can I use AJAX instead of PHP to do that? or change the way the PHP works...
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.
I have the html and the file from server look like this
html Code HTML4Strict: <div id="container"><a href="#">load form</a></div> file from server: HTML Code:
[Code]....
So basically when i click on load form, the form loaded to the div#container , the link 'load form' disappears. When clicking button 'hide div' the form hide and the link 'load form' reappear.
I have a form whereby I can add multiple contacts to a single address. There is only one firstname/lastname/telephone box - when the user clicks the add button, I read the values from the form fields and record them into a hidden text input field. This part works because during debugging, I have converted the <input type=hidden> into a <input type=text> to visably confirm my data is being copied into the 'hidden' field.
Once the user has entered in one or more names, they can click another button and submit the form for processing. My idea is that I would then parse this hidden field server side...
I have a WAMPHP based server and as a test, I dump out my entire $_POST (basically, the name and value in every INPUT tag).
My PHP script picks up the name of every input tag, including the hidden field (like it should) but for some reason, the value that was written to the hidden field is not passed to the server. Thus, for the PHP folk reading this post, my hidden input field is called mylist and $_POST['mylist'] exists, but its empty. Even though before processing, I could visably see the input in the box (for debugging remember, I made the input tag box a normal, unhidden one).
Here is what I have done to try and resolve: - I have used both Mozilla 1.7.5 and IE6 - both provide same results - my hidden field name gets passed, but not its value.
- I have created another hidden field and given it a default value ie I have <input type="hidden" name="extraone" value="xyz"> and I get $_POST['extraone']="xyz" passed to my php server, like I would expect - however, the value of mylist is sent empty, even though it has data.
- I have even put in a javascript alert box just before the form is sent to the server and can see the result in my (unhidden) box, and the same value displayed in the javascript alert - but again, the value of the mylist does not get sent to the server.
The only difference is that my hidden field (even if its displayed like an ordinary text input box) does not post data written to form fields as the result of a javascript function. Interestingly though, the server does know about the input tag box since it does receive $_POST['mylist'], it justs receives it empty.
What gives? If the form reads my input from one field, and writes it to another field, then it should be sent to the server, true?
Also... my tags are all inside my <form></form> tag (which is proven by double checking, and the fact that I do get the input tag box name sent to my server).
Since I can see the data values in the box, it tells me my javascript is doing what it should be doing - so I don't see any point in including my javascript (though I have no problems doing so if someone requests it). On the php server, I am using a simple phpinfo(); to check the data is being received...
Do you know a dynamic way to send 10kb of text or more using an iframe?
I tried to do that with by creating, in javascript, a dynamic iframe, then create a form into this iframe and put the data in a textarea and then call a sumbit(). Code:
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.
Here is what I am trying to do. On my web page, I have three choices for the user to pick from. After the user selects one of the checkboxes and clicks a submit button, I need to send a http request to a remote server to record the user's choices (actually it is an https that I am sending),.. so I need to send something like this.
[URL]
The remote server responds with an xml response that looks like this:
So, I want to post the request, read the response (answer) back from the other server and display it on my page. So, my dilemma is as follows:
1) my understanding is that I cannot do this with AJAX using an XMLHttp object because it is on a remote server and it would violate some sort of same-domain security. Is that correct? If in fact I can do it in AJAX, how do I read the response back from the other server?
2) if I am correct in my assumption in 1) then what is the best way to accomplish this task?
I am having trouble sending JSON data to a server. Its definitely reaching the parser.php, but I am not what to create in PHP to fetch this data. Also I am not sure my Javascript is correct.
<SCRIPT> var JSONObject = new Object; JSONObject.description = "hello"; JSONstring = JSON.stringify(JSONObject); runAjax(JSONstring);
I am trying to send the login info from a form into a IIS server and the asp file on the server will just respond back with the following text "Welcome, &name" on a ajax form on the client side. Currently, i am using a GET response and would like to send using JSON instead.
well i'm kind of new to this website and scripting with javascript but i am wondering: in a client side .js file i have some coding which results in a string which is stored in a variable called exportData
now i want that string to be written into a text file on a server but how do i do that? it is not local on the client's pc and i can't find how to do it anywhere..
I am using Ajax to send a large text box to a server script, however, when the textbox has a lot of data it fails. Is there a better way for me to do this? Here is my code.
Code: <script type="text/javascript"> function testmail() { if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
is there a way to send data to the server through a form , and then receive the response from the server without reloading a new page? kind of like the LoadVars object in flash?
I know at this point is that these is a difference in the array formatting between PHP and JS. The magic bullet is supposed to be json. However, this code does not work as advertised.
[Code]...
The variable $prt is list of associative arrays, so to get a value in a particular row manually , $prt[0]['location'] should give me the value for location in the first row of output. All of this works just fine if i hard code this in html and php. However, I want to dynamically produce the rows as needed which requires that a loop employed. The application also requires that the user may add a row which also need to be accounted for when posting.
I think the best solution is to make this a totally javascript entity. All I need to do is to be able to pass in the server side data. Calling JS from PHP does not work, although i have found many places where they show basically the same code , claiming that it works. think json needs a bit of tweaking to make this happen, but i'm not sure how to proceed.
I have a few values and variables that I want to post to a server (without using a SUBMIT button). Is there a way to post data from within javascript - do sockets or connections have to be open for this to work?
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.
