I'm trying to create a "Books I'm Reading" widget using the Readernaut API. I'm using JSON with a callback. This is a portion of what the JSON URL returns:
Code JavaScript:
parseResponse(
{
"version": "1.0", [code]...
I'm having troubles with an existing J2EE application (which uses Dojo) and in which I'm gradually introducing jQuery. The specific issue is with the malsup Form plugin and the JSON returned from a form submission: the error callback is always called, regardless of what happens on the server side, and the error is always "parsererror". I'm using jQuery 1.4.2 and the 2.45 version of the malsup Form plugin.
For example, given the following code:
$(document).ready(function() {
var options = {
dataType: 'json',[code]....
the server receives the submission and handles it without errors, then in the browser I always get the same alert from the processAddressEditSubmitError() function, with an "Invalid JSON" message:
pStatus=parsererror
pErrorText=Invalid JSON: {"nickname":"trytrez","success":"success"}
However, the JSON looks OK for me (and http:[url]...agrees that it is valid).
I've been hitting a strange bug where callbacks are not invoked when a JSON response is returned from an AJAX call under jQuery 1.4.1. I just upgraded my app; this was working perfectly pre-1.4.
I do specify the return type as "json" when I invoke $.post . When a simple JSON string like "false" is returned, the callback is invoked. It seems to fail with more complex types, specifically with JSON objects, i.e., {"a":1, "b":5} .
If it helps, I'm running Firefox 3.5 on Ubuntu. In my test environment, the only installed extension is Firebug.
I am using a json from a Google spreadsheet and a jquery plugin which is called throught this HTML line <ul id="example">.The thing is that when I dynamically append elements to the <ul id="example"> from within the JSON callback function, these are not recognized by the jquery plugin
Code:
<form>
<ul id="example">BLA BLA BLA</ul>
</form>
[code]....
If I insert an <ul id="example"> plus some <li> in the HTML code the plugin works perfect If I insert dynamically some <li> to the <ul id="example"> throught a javascrypt function before executing the callback (...json-in-script&callback=...) also work perfect.But when I insert dynamically the <li> elements within the callback function (in my case: cm_loadMapJSON) does not work well.
I am looking for a solution for many days: my callback - function works well in firefox 5, IE8, but not in safari, opera, IE7 etc. The function "checken" is not executed. There are no error messages in the debugger of safari or IE7.
var session_id = $.cookie("fe_typo_user");
function checken (nummer){
var elem = "#img" + nummer;
$(elem).attr('checked',true); }
var url = "refreshCheckboxes.php?id=" + session_id;
$.getJSON(url,function(data){
$.each(data.posts, function(i,data){
checken (data.number);
}); });
The response of the script:
{"posts": [{"number":"1325"},{"number":"1303"},{"number":"1302"}]}
html (example):
<input
type="checkbox"
id="img1325"
class="merkzettel"
name="merkzettel1325"
value="img_1325.jpg"
/>
You can test it here: [URL]. Activate some checkboxes, load another site and then go back to this site and the checkboxes you have selected, must be activated by the script.
I'm trying to assign the values from the JSON data returned when I run this code into an array that's outside the callback function. The data is multidimensional, and I have been able to use this data within the callback function. However I want to use it outside that function. i.e. the jsdata returned in the code below is to be used outside the function
Code:
$.getJSON('../fxns/status.php',function(jsdata){
//do some stuff with JSON data or pass to global variable[code]..........
here is my code
function fadeInFeaturedGame() {
$("#featuredgame").fadeIn("slow", setTimeout("fadeOutFeaturedGame()",
5000));
[code]....
Why won't this work?
Nothing pops up for the alert.

For some reason the success and error callbacks are not working at all. I'm using jquery.ajax to submit a form w/o page refresh through a php file. I have set the success & error callbacks but even when I changed the mysql password (to a incorrect one) I got the success message [code]...

What I noticed is that my error callback is fired every time.
MyService.asmx:
[WebMethod]
public FileInfo[] GetFileInfo(int Id){
Proxies.ServiceRef.ServiceClient c = new Proxies.ServiceRef.ServiceClient();
return c.GetFileInfo(Id).ToArray();
}
The Jquery code where I am getting error:
$.ajax({

data: jsonData,
type: "POST",
contentType: _I.contentType,

When I debug using firebug the response is as follows.

I'm using an .ajax() call to do a jsonp request to another domain. When the user is not logged in, however, the server will return a 401 error. Unfortunately, this causes my .ajax() call to fail _without_ calling the error callback. Is this a known bug? Here is my code:

I'm using this star-rating plugin [URL] and the call back function provided to allow for submission of forms onclick of rating star.
Code:
$(document).ready(function() {
$('form.entry_rating').rating( {
callback:function(value, link) {
alert(value);
}
});
});
However, once the callback is included I get an error I've been trying to track down for the past day and a half. In IE the error thrown is "Object doesn't support this property or method" on Line 100 character 4. In my JS debugger the plugin breaks on line 99

Sorry this will be an ignorant question I know, but I'm just trying to implement some quick JS in my form to check if the fields were filled in:
function check_form() {
if (survey.form_firstname.value == "") {
firstname_error = "-Please enter your first name
";
}
if (survey.form_lastname.value == "") {
lastname_error = "-Please enter your last name
";
}
if (survey.form_phone.value == "") {
phone_error = "-Please enter your phone number
";
}
if (survey.form_email.value == "") {
email_error = "-Please enter your email
";
}
if (!survey.form_agree.checked) {
agree_error = "-You must be over 18 and provide accurate information
";
}
errors = firstname_error + lastname_error + phone_error + email_error + agree_error;
if(!errors) {
return true;
} else {
alert("There were errors:
" + errors);
delete firstname_error;
delete lastname_error;
delete phone_error;
delete email_error;
delete agree_error;
delete errors;
return false;
}
}
It only seems to work if no values are filled in, if one of the fields is filled in the error checking fails. Again, I'm extremely new to JS, i've only ever copy/pasted and this is the first time i've tried writing a piece.
I'm getting a runtime error on the code in red. These functions are called by an onBlur by the way.

I know I have a simple syntax error. Trying to call a function which changes the style of a div element on mouseover. Heres my code.
Javascript
function countermarker1(){
var box1 = document.getElementById('countermarker1box').style.display
box1 = "block" }
Variable is used cause I will have to use it more often later in the script.
HTML
<div id="countermarker1">
<img src="countermarker.jpg" width="20" height="14"
onmouseover = "countermarker1()"; /></div>
CSS (know its not really relevant just to avoid questions about whether its right)
#countermarker1box {
height: auto;
width: 80px;
display: none;
}
JS and css is externally srced.
