Response Is Null When Calling $.getJSON On A Remote Server?
Jun 24, 2010
I have a drop down menu with a change event that makes a JQuery JSON AJAX request, which I've simplified for this post:
Code JavaScript:
$('#id_template').change( function() {
var data = {
action: 'change_template'
[Code]....
When I do change the drop menu's value, the request seems to be successfully sent with a successful reply received (inspected it in Firebug), as the content in the "status == success" is accessed. However, the problem is the response is null.
I don't have this problem when I'm testing on my local WAMP setup, and so have no idea why everything appears to be working fine here except the retrieval of the response array.
I am using the getJSON command and using firebug for debugging, if I go to this server i setup with this url: [URL] It returns json data warped with getdata({data}). I have validated the json part using jsonlint, so from firebug's net tab I get a param (callback getdata), header and response, etc. as expected. But if I use jquery's getjson, I get param, and header but the response is empty and function callback doesn't trigger (no alert). (I know that getjson uses OPTIONS instead of GETS and I can see that the request is made on the server and the json should be sent as normal). Here is my code for this section:
<script type="application/javascript"> function getdata(data){ alert(data.name);
I have been trying for several days to get the response from a $.getJSON query to PHP which gets records from MySQL. The attachments show the code I think is messed up and a screenshot of the results and firebug data.
I have a little problem while trying to refactor my jquery [code]...
But i will assign the data dynamically. When I use an alert(inputName), then behind the var is the correct String "SomeName" which is also set in the Json response. Is there any way to solve this?
I'm using getJson() to call a web service that returns a very long json string. like 350k characters. the response comes back in its entirety from the server. and i can see it in the net tab of firebug. but the jsonp callback fails because the response text is truncated at character 28816.
the only error in firebug is "invalid property id" jsonp1269473615362({"d":[{"__type":"Client","ClientId":1,"AccountNumber":"11... it's because the json string isn't terminated properly because it was truncated. if i change the amount of data being returned to a low enough threshold, it works fine.
is this some sort of built in limitation? it's not an issue with the max size of a javascript string. so i'm not sure what else it could be.
I am hosting my website in free server (freehostia.com) and i am using joomla1.5 . I want to parse RSS from my other websites. Joomla does it with its modules. But the server do not allow outbound HTTP request, hence i had use rss-to-javascript website to parse RSS feeds. It parses well but there is its advertisement below the feed (which i think is nonsense).
I am calling a program using $.getJSON() inside of a for loop. The problem is that the second callback doesn't wait for the first program to finish before it executes. Is it possible to ensure that the second iteration of the loop doesn't happen until the first one is finished?
$('#dialog-form').dialog({ buttons: { "Import": function() { var ids = $("#itemsGrid").jqGrid('getGridParam','selarrrow');
I want to populate my client's webpage (Remote Server) automatically through my Server and Database by having him just paste a javascript on his webpage.
I have read up about Microsoft Remote Scripting but the documentation states the following : "The server which you make remote scripting calls must be the same server from which you requested the client page containing the requests."
In my case , the client and server pages are on two seperate servers which means that I cannot use MS Remote Scripting.Is there an alternate approach in any scripting language ???
Any suggestions, tutorials , websites , code snippets will be appreciated while i continue to research on this...
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.

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'm building a very simple app that relies on a remote server. I will use this app on many websites, so I decided to store it on one server (I have control of the remote server in question).
I need to make sure that this server is up and running, so in the case it's not I can use a fallback.
Would it be a client-side approach? A server-side approach? My guess is to use a js snippet to do the job. If I'm correct, I'll probably use jquery to perfom the task.
I want to get the solution for a null xml response at the moment if there is no error i made a work around so the xml returns a fullstop which shows up as an error but in white. I would like to know if there is a way to keep the elementByiD as null when the xml is null as it was returning the error object required is there a better way of doing this????
I am developing extension which should upload currently displayed html as a file to a remote web server, unfortunatelly so far i haven't suceeded. I think this should be done through XMLHttpRequest(), but neither I know how to upload files through XMLHttpRequest nor how to convert string to file.
The HTML form that uploads a file:
But as I said i need my plugin to do it automatically and file must be made from html code.
I am running the scripts below which should return a string containing a URL. So far, it cannot find the form contents in Firefox, but displays the non-dynamic data such as ?Location=. It won't work at all in IE.
HTML Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head>
I wanted to ask how it is possible to get error messages from the server till it is implemented in the remote method.What do you think is the less work intensive alternative.I also wanted to ask if i have two fields A and B, and the values of B depends on A. How do i make it with the plugin and the remote method ?I saw that there is a way of writing custom methods:URL...But how do i combine it with the ajax calls?
I have a list where each list item has a click event attached to it. Upon clicking a list item, the click calls a PHP script and passes the list's title attribute as a parameter to the script. How can I take the data returned (some HTML) from the AJAX call and append it to the list item which was clicked? I know that the data variable contains the correct HTML coming back from the script and thought that $ (this).append(data) would work but it doesn't. I was thinking of calling another function from within the AJAX return function call, but don't know how to reference the list item which was originally clicked.
<form action="https://checkout.google.com/api/checkout/v2/checkoutForm/Merchant/XXXXXXXXXXXX" id="BB_BuyButtonForm" method="post" name="BB_BuyButtonForm" target="_top" > <input name="item_name_1" type="hidden" value="Test Product"/> <input name="item_description_1" type="hidden" value="Test Product of my cart"/>
[Code].....
On hitting the button one new window is getting opened with response URL from 3rd party(in this case Google Checkout). But for me i need to open this in a inline-popup (lightBox, ColorBox etc...) rather than new window. In the form definition, i have replaced mymerchant_idwith 'XXXXXXXXXX' for privacy purpose
I'm having two Ajax-related problems on a page I am working on at the moment. [url] On this page, I have two buttons that use Ajax to fetch two separate forms and put them into a chosen div; that part works like a charm.
On said forms, there is a div that is meant to display any necessary error messages when the submit button is clicked. However, on the first time the page is visited and the form is chosen, the div won't display the error message. Only after refreshing the page/choosing the form a second time will the message show. I've been checking the response from the server via Firebug and the response is correct, it just seems like the page isn't updating correctly.
Secondly, once I refresh or choose the form again and the error message begins to show, if I enter values into the form fields and should be getting a different error message, it never updates. Once again, the server response is correct, but for some reason the page just isn't updating to reflect the new message.
I have been using the date field on the New Event form for testing; if you have Firebug, you should be able to see that I am getting the desired response from the server (look in the allErr div), but the HTML isn't changing with it. I have tried both using my own Ajax functions and using jQuery's Ajax implementation, but both give me the same problems.
I am using jquery.ajax() to make a POST call to web server which returns HTTP 201 response for successful creation of object at server. Since 201 is a success I expect the success function specified with jquery.ajax to execute but instead it executes the error function specified with jquery.ajax. Here is how I am using jquery.ajax call.
A couple of months ago I posted a question in these forums pertaining to some trouble I've been having with a webpage utilizing Javascript and PHP to implement AJAX.

I am developing an ASP.NET (C#) application and need some help. I wish to call a server-side function (in the code-behind "file.aspx.cs") upon a user clicking on the "X" to close the browser window. Is there a way to postback and call a server-side function when this happens? I am aware of the browser's native "onunload" event, but am not certain that what I'm looking for is actually possible.
