I am making an AJAX call using $.getJSON
I get empty response. I am making a same domain call.
Here is the code am using:
$.getJSON("<url>",
{
parameters...
},
[Code]....
I am using firebug and can see the URL and the parameters. The response is always empty.
The goal is to change the source on the fly (as with a firefox extension webdev or another or even Greasemonkey) to add a link. Until then, easy does it work well. This link launches an application ajax jquery like:
$.get(...) or even $.ajax(...)
If I'm on [URL], added my link, I click and it works, I see the ajax request and pass my "alert ()" gives me the return of application. Great! But if I'm on a site other than mine (the url of the ajax request is [URL] while I'm at [URL] for example), the return of the ajax request is empty.
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);
[Code].....
I'm doing something with grails + jquery. My controller send a rendered json (which I know is sending correctly) but when the object "arrives" in the callback method it comes undefined. I can see it lenght, but not it's content.
[Code]...
I have been trying for several days to get the response from a $.getJSON query to PHP which gets records from MySQL. The attachments show the code I think is messed up and a screenshot of the results and firebug data.
[Code]...
I have a little problem while trying to refactor my jquery [code]...
But i will assign the data dynamically. When I use an alert(inputName), then behind the var is the correct String "SomeName" which is also set in the Json response. Is there any way to solve this?
I'm using getJson() to call a web service that returns a very long json string. like 350k characters. the response comes back in its entirety from the server. and i can see it in the net tab of firebug. but the jsonp callback fails because the response text is truncated at character 28816.
the only error in firebug is "invalid property id" jsonp1269473615362({"d":[{"__type":"Client","ClientId":1,"AccountNumber":"11... it's because the json string isn't terminated properly because it was truncated. if i change the amount of data being returned to a low enough threshold, it works fine.
is this some sort of built in limitation? it's not an issue with the max size of a javascript string. so i'm not sure what else it could be.
I have a form with an id "modClassForm" when I try:$("#modClassForm").serialize() it returns an empty string ("") When I get the action attribute it's right so it is the form I was expecting. When I do the following:
$("#modClassForm input").val()
it returns "retret" (the contents of the input element in that form). So what is doing this? The only thing I can think of is that this form is loaded from ajax and then placed in the page using the .html(htmlString) method which is rather core to my design. This works in a whole lot of other browsers (IE 9, FF 6-8, Chrome 13-15 and Safari 5). So I know I could try to serialize the fields myself, but the form content has two modes and I'd have to construct a fairly large string and I'm not sure about encoding. Is there any other way to make serialize work? Some way to get it to recognize the contents of the form?
I am making a call like -
$('#display').load(adnwurl, function(response, status, xhr) {
alert(response);
});
And also tried with -
$.get(adnwurl,
{},
function(data) {[code]...
In both the cases I am getting an empty response instead of expected html response.If I just copy paste this adnwurl in browser, I do get a proper html response. Its not working with ajax call.
adnwurl = "http [url]...site_id=4764&partner_id=70606a913077034c&timeout=5000&version=1.5&language=jsp&format=wap&testing=1&target_params=AGE=>29||DOB=>1981-08-[code]....
If I do this I get a result for test
var test = $.get('manualAddress.cfm');
but if this, test is an empty sting
var test = $.get('manualAddress.cfm').responseText;
While using jQuery, I found that I needed to know how many records were returned and also if the result set returned was empty. After searching the jQuery documentation I couldn't find any property or method that returned this value, so I've added that functionality
myself and wanted to share it with the group.
1) Determine the number of records returned: I wanted to show the user how many results were returned after they start typing into the autocomplete field similar to how Google indicates the number of results found when you start typing in the search box. At first I thought the max parameter in the function formatItem returned this value. However, it returns the max option that you set it to. So if your query returns 100 records and you set max to 25, it'll obviously return 25 (not what I wanted).So after trying various things, I looked at the jQuery code and simply added the number of records returned by the database to the formateItem function. In the fillList() function around line 660 I added the data.length parameter:
var formatted = options.formatItem(data[i].data, i+1, max, data [i].value, term, data.length);And in my autocomplete code, I added the parameter to the end of theparam list:formatItem: function(data, i, total, value, searchTerm, totalResults)So now whenever a new search is preformed, I get back the number ofsearch result from the database.
2) Determine if a result set returned was empty I wanted to update a <div> with a message like "no records found" whenever the query yielded no results. Again, after searching the jQuery documentation, I couldn't find any property or method that would indicate this so I added it to the code. In the request function after the line var data = cache.load(term); I added the following:
if (!data) {
options.isEmpty(0);
} else {

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.
Two ajax and php files are located in a domain. and, ajax is calling in another domain. Why get a response from php is empty? While not empty. Like the image attached.
View 3 Replies View Relatedser is able to create queries and issue them. The query is sent to the web-app by means of an ajax call. Then, the server computes the result set and a small subset (100) of tuples are sent back to the client for visualization.
These thing works with queries that are simple and do not require to the database long computations. As soon as I try a more complex query (computation requires ~ 7secs), the answer returned to the client is empty.
I suspect that this is a problem of timing out the connection, is that possible?
(edit) I have almost forgot, I'm using Prototype as JS library
Either I'm having a really dim Friday, or something strange is going on. I'm trying to add a method to the Validator plugin, using the following regex:

I have an ajax post which returns a large html response. It is getting truncated at 98784 characters everytime. Is there a limit to a response size or a way around this?
Using: IE7

jQuery UI 1.8.1
Here is my ajax call:
The .find() method does not seem to match on input fields by using a class. The ti This problem seems to be only visible on input fields. The following is a demonstration of the issue:
Example at [url]
Trying to upgrade from JQuery 1.4.3 to 1.6.1. My getJSON queries no longer populate my SELECTs. The below code works perfectly in 1.4.3 but unsure what changes I need to make for 1.6.1.
function populateCause() {
$.getJSON(urlQueries, {sql:'list_causes'}, function(data) {
var select = $('#opencause');
var options = select.attr('options');
[Code]....
The ONLY change I made is sourcing JQuery 1.6.1 instead of 1.4.3. Evidently I need to change the method of parsing the JSON data also.
The problem I'm facing is as follows. I'm using a JSON call to checksome data before doing a JS redirect to a different page. The redirectworks but it's impossible to get back to the initial page using thebrowser's back button. The initial location is not being stored in thebrowser's history.This is the script simplified.

After upgrading to jQuery 1.4.1 from jQuery 1.3.2, my getJSON requests fail.The error given to the ajax error handler, is "Invalid JSON: ..." where "..." is the text of the response.Firebug parses the JSON fine, and can display the JSON data as such in its console, and jQuery didn't have an issue with the same data with version 1.3.2.

But if I view the "contents" tab in httpfox I can actually see the data under <sourcetext> I require but there is an XML parse error.
<?xml-stylesheet
href="chrome://global/locale/intl.css" type="text/css"
?>
<parsererror>
[Code].....
The NS_ERROR_DOM_BAD_URI seems to be about cross domain issues but I'm working locally on the actual server so should I be able to access the data? Also why is there an XML parse error when I can see the exact data I want in httpfox's "Content" tab?
I have setup a little example here: [URL] It is JSONP because of cross site policy. The returned JSON is valid, you can check the response in firebug. The callback function is not fired.
Tested with jquery 1.3.2, 1.4.2 and 1.4.4. Same result.
Although i used getJSON in [url] i have not been able to connect with any of my own made up data. i tried 4, and the example at Flickr for "cats".
Only the latter worked... this is the output:
I am at that "base", as i did get the image there, but
[url]
[url]
[url]
[url]
Were all invisible==null!
How do i get "my" data into the page?
In jQuery 1.4.4 I could load a JSON file from subdomain2.website.com to subdomain1.website.com without any problems. When I upgraded to jQuery 1.5 this didn't work anymore.
Is this a jQuery bug
$.getJSON("http://subdomain2.website.com/resources/data.json", function( data ) {
console.log("data");
});
my $.getJSON method is not working, although $.get method works correctly.
I have posted my code here

I find jQuery very hard ..... if things don't work they just don't work quietly..
how to start debugging the code? how to get some error messages from jquery?
I have this basic code following and its not returning anything at all. Even the alert is not alerting. I have checked and the select is sending the value fine But nothing happens on return. What i am missing?
$(function() {
