JQuery :: Can't Parse JSON Results
Jan 4, 2012
I am having difficulty displaying a specific key from a json file. I am trying to parse the following json file using query:
[URL]
I am using this type of function to parse the data:
$.each(json.route,function(i,route){
<!--add a paragraph tag to the results div and enter the speficied key-->
$("#results").append('<p>Result: '+ route +'</p>');
Using this I am able to print all the keys from the route but I am not able to print a specific key.
What I want to do is just get the results for the key "fuelUsed" using this method:
$("#results").append('<p>Result: '+ route.fuelUsed+'</p>');
But I never get back any data that way. Am I not specifying my key correctly?

I am trying parse a json request.
The json response is
I have tried to console.log the item in a number of ways including: arrayToParse[item] item[1] item[0]
I either get the key of 1,2,3 or undefined. How do I get the values in this scenario?

How can I adequately parse a JSON response I'm getting from the server, which happens to be an array?
The array I'm getting back is actually this one:
[{"photo":{"created_at":"2011-02-26T18:40:00Z","id":5,"name":"Natalie_Portman.jpg","updated_at":"2011-02-26T18:40:00Z"}},{"photo":{"created_at":"2011-02-26T18:40:14Z","id":6,"name":"scarlett-johansson-.jpg","updated_at":"2011-02-26T18:40:14Z"}}]
I believe this one is valid JSON, but my attempts to parse it are always failing when I do it like this:
success:
function(data, textStatus, xhr)
{
var photos = jQuery.parseJSON(data);
alert(photos);
},
The above code displays 'null', and the documentation says a null occurs when the JSON isn't valid. so, what's going on ?
I need to know the codes to parse as well as access the values in the parsed response.

I am submitting a form via AJAX. The form may either return HTML (when there are input errors) or JSON (successful response). If during request I specify "dataType: 'json'" then HTML doesn't get thru correctly, if I don't then JSON is displayed as plain text. I am sending the "application/json" header back correctly. I don't understand why doesn't jQuery just pick that up and parse it as JSON? Is there an option? Is there something I can do to make this work?

I have a wordpress site with dropdown menus that currently are working with jQuery, now the issue is when trying to dynamically update the menus and parsing it with json.parse. For some reason I am not getting any data back of the following code (if I try to alert (data) I just get a blank box).
function waitGoUpdate()
{
var $jQ = jQuery.noConflict ();
$jQ.ajax ({
[Code].....
and just print out the function, than I would get the data on screen. now if I was to access my php file directly than that fill will output an error due to missing plugins.. I guess that is just how wordpress sorta work.. but again I do get the info that i need by just printing out the function. Do anyone knows a work around for this? I am kinda pulling my hairs out.

I'm trying to parse a Json string received by $.getJSON(). I can receive the string but firebug gives me an "invalid label" error. I think it is because the string is an hash array with a number as first label, but I'm not sure. This is the string:
{"15":{"id":15,"x":0.4589937586135409,"y":
0.8324914620560137,"z":-0.9435707004102728,"rawData":"1256204002860 13
-442866538 18392602 647462767 314 1777206957 -1664784174 "}}
and this is the non-working code:

Can anyone explain me why you need to add open and close parenthesis to
a JSON text in order to use eval() to parse it?
For example:
var json = "{a: 'abc', b: 'def'}";
var obj1 = eval("(" + json + ")"); //ok!
var obj2 = eval(json); //syntax error!
why are parenthesis necessary?

Why is it necessary to eval or parse JSON data?If it is legal JS, why couldn't I just name the file in the src attribute of a <script> statement?

I have client-side javascript that is using AJAX to receive JSONs from a server-side database-querying php script. My application is working fine in firefox and chrome. IE8 is giving me trouble, however. The error I get is:
Message: 'JSON' is undefined
Line: ###
Char: #
Code: 0
URI: http://...
Does anyone know if their is a different function or library include I need for IE8 in order to work with JSONs, more specifically JSON.parse()?

so, the pseudo code: - on change of input contents, check to see if two input fields are set - if set, update a third field with "loading..." text and a loading gif - use ajax to send data to a url, and get a calculated json response - update the third field with the calculated response
I know I'm getting the correct response, according to firebug: {"pace":"10:00"}
the code:
$('#run_distance').change(function() {
if ($(this).val() != '' && $('#run_time').val() != '')
{
$('#run_pace').val('Calculating Pace…');
[Code].....
how to update the #run_pace input field with the json response.

I've got this:
Code:
var noteCount = "";
jsonRequest('media.getFiles', params,
function(result) { noteCount = result['totalCount']},
function(exception) { noteCount = "0"},
true
);
The console returns results['totalCount'] with a value of 2 (that's correct).
When I call noteCount for display, it shows nothing. Neither the var set by result or exception.

I have a html file that I want to load, loop through the json data and for each json entry I want to add a new block of the html and insert the json data into the matching div/class of the html. json looks like this:
{"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
html looks like this:
<div class="Name"></div><div class="Age"></div>
So for each json entry of name/age, I want to insert that into the html, and then add another row, until all json data has been fetched. After this I want to insert all of this into #box, which is just a divthat should contain that html. Looping like this obviously does not work, since I just keep replacing the same html through the loop.
var jsonData = {"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
$.each(json.Super, function() {
$('#box .Name').html(this.Name);
$('#box .Age).html(this.Age);
});

I have a JSON structure in API.When I call the API in my code it returns as the same JSON .I have to print this JSON result as table with pagination in Javascript.

I am using the infamous hidden IFRAME trick to manage some image uploading. My server-side ASP page passes back XML to indicate success or failure. It was a snap to grab this in FireFox and parse it using the standard JQuery methods. Then I spent most of an afternoon trying to do the same in IE, I finally found this page and this comment: [url]
JavaScript, IE, XML, IE uses MSXML and an XSL stylesheet to transform the XML to some HTML document that pretty-prints the structure of the XML. That way when you access the iframe document you indeed access an HTML document that IE renders. However IE stores the original XML document in an XMLDocument property of the HTML document object so to access the XML data (and not the HTML document) you can do e.g. var xmlDoc = window.frames.frameName.document.XMLDocument; [...]
The solution thus ended up as follows:
From there I can use all of the normal JQuery code to traverse the XML. Anyway I am not sure if this is an IE bug, a JQuery bug and/or presumably specific to this wacky IFRAME scenario versus a normal document.

I am trying to get two values from a web service response.
The web service was called using jquery $ajax:
$.ajax({
url : "http://localhost:3032/ufs/integration/copymoveTerm",
type : "POST",
dataType : "xml",
[Code]....
All I want to do is to get the values of UNDO_COUNT and MSG into separate variables.
Here is the jquery I am trying to use:
function undoSuccess(xmlData, status, xmlResponse)
{
$(xmlResponse).find('res:OUTPUT').each(function () {
var undoCount = $(this).attr('res:UNDO_COUNT).text();
var msg = $(this).attr('res:MSG).text();
});
}
I have tried it with and without the name space "res:". I have tried it with xmlData and with xmlResponse I have tried changing the web service so that UNDO_COUNT and MSG were elements in their own right or were attributes of OUTPUT all without success it just bypasses the initial find on OUTPUT.

I have the need to grab the HREF value from a link to an image, parse it, append it with "-144x127" and reassemble it for use as the src for a dynamic thumbnail. I have the following worked out, but... surely there's a better way?
[Code].....
Of course it would be a lot easier to split on the file extension, but I won't necessarily know whether the file is a GIF, PNG, JPEG... so...?

I'm trying to get jquery to parse some text in a variable as HTML, has anyone tried this before and got it to work? Can this even be done, or do I have to parse as text?
<CODE>
testHTML = "<html><head></head><body><ul><li class='targetMe'>TESTING</
li></ul></body></html>";
testGetHTML = $(".targetMe", testHTML).html();
alert( testGetHTML );
