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?
I want to do a Ajax GET request and then parse the resulting HTML to get a list of products from that page:
$.get("http://www.americanas.com.br/busca/baskervilles?dep=256705", function(data) {
var domData = $(data);
alert($("div.hproduct", domData).length);
});
This doesn't work. I get an error ("div is null") right on the first line of the function. The error is from jquery code.
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?
Supposed that I have a json object but I don't know anything about its keys and values. Is there anyway to print out all the key and value pairs in that object?

JSON.parse('{a:3}')
I get: "SyntaxError: JSON.parse"
I have put up an example at:
[URL]
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 ({

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

Nothing pops up for the alert.

View 1 Replies View RelatedI need to parse an HTML string received from an AJAX request. I wrote a function that places the HTML string into an unappended (not added) <div> , which opens the string up to the DOM hierarchy. However, when I try to access the elements of this <div> , I get an error in the console that says root.getElementById is not a function. This tells me that I can't access any of the child nodes.
Here is what my script looks like:
function parseHTML(html) {
var root = document.createElement("div");
root.innerHTML = html;
// The error console stops at this line
[Code]...
I have troubles with a simple jQuery.ajax-request which looks like this:
jQuery.ajax({
type: "GET",
url: "[URL]",
//url: "[URL]",
data: "",
success: function(data, status) {
$('body').html(data);
},
dataType: "json"
});
I test this with two different url's:
[URL]
[URL]
The first url works and I get json-data in the data-object. The second url gives a "parseerror", and I can't figure out why. As far as I can see (and using a json-validator) the second url returns valid json, so what's wrong?
I got a problem with a json response from an ajax request.
I have the following code :
Code:
And the called page (ajax_sous_famille.php) is giving me this result :
Code:
The info in the resulting string is correct, but here you can see the [ ] at the start and end of the line. It seems not to be a correct Json string and then it crashes my script !
I have another request like this which gives me the good format of resulting data (without the [ ]) and which works perfectly when i decode the Json string to display it.
The difference between the 2 requests is that the one which works returns only 1 array of values like
Code:
And the second one which doesn't work returns something like
Code:
Actually, all the records are coming from a database and in the case it doesn't work, i wanna get several results from this database.
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 I have a function that is going to get a URL, and have to retrieve json data from that URL. The URL _might_ be same-domain, and might be cross-domain. If it's cross-domain, of course I want to do jsonp complete with the script-tag-to-load and such, but if it's same domain of course I want to do just xhr for efficiency. So I _could_ write all my own logic for this. Write logic to see if the url is cross-domain or not, and then make entirely different $.ajax() calls depending.
(I think I need to use $.ajax() rather than $.getJSON() because I need a callback on failure, not just success). If it is cross-domain, use dataType:jsonp, and make sure to supply a &callback. If it's not cross-domain, dataType:json, and don't even bother supplying a callback. But I'm having trouble figuring out if this is true, or how. What's the easiest way to get $.ajax() to make a dataType:json request if it's same-domain, but a dataType:jsonp request if it's cross-domain?
I'm using some jQuery to work with the Last.FM API, and I'm stuck where I need to allow the user to run the JSON request a second time after the page loads (it loads once automatically when the page loads, the second time is when they push a button). What happens currently, is the JSON function is fed some default data when the page loads:
$('#graph').lastFM({
username: 'UserName',
from: 1254369600,
to: 1256184000,
apikey: 'myApiKeyHere',
onComplete: function(){
//Done
}});
The JSON function:
$.fn.lastFM = function(options) {
var defaults = {
username: 'Verdani',
apikey: 'e4f3bb251d13179bf7ce80a089fb3d0c',
onComplete: function(){}
},
settings = $.extend({}, defaults, options); .....
You might have noticed in the JSON, I write the URL the JSON is requesting to the console every time it runs. When I click this button, a new URL pops up in the console below the first one but only for a second, and then the page reloads and the original JSON request is called. It's this loop that I can't seem to break out of - why does re-calling the JSON refresh the page?
I am doing a JSON request to get data back from a PHP file. On the return of that data, I am using a for loop to go through the data and post it up using JS. Here is my code:
for (var x = 0; x < data.length; x++) {
//create a container for each comment
var div = $("<div>").addClass("entry round").appendTo("#characters");
//add author name and comment to container
$("<div>").addClass("details").appendTo(div);
$("<span>").addClass("main-armory button").appendTo("div.details");
}
Now, what is happening, because there is 10 entries being posted, my JS is looking at the class that is being put together (main-armory button) and making it so that class appends every run through. So, I want one entry for main-armory button and I am getting this:
<div class="details"><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span></div>
And then, when it goes down to the next entry, it has 9 spans, and then the next entry has 8 spans, and it continues all the way down. What is going on here that I am missing? I know that I am not clearing a variable properly or something is wrong within my loop.
The following request isn't retrieving a response when I look for it in Firebug. Any ideas why?
$function(){
//json request to flickr
$.getJSON('http://api.flickr.com/services/rest/?&method=flickr.photosets.getPhotos&api_key=71282ef5623d61a898f798c7916bed31&photoset_id=72157627882181032&format=json&jsoncallback=?'),
});
whats the best way to pass a json string to the server.
if my jsonstring = {a:Ƈ',b:'sds',c:'sdg'}
could i send that to the server passing it as 1 variable like so:
url = /serverside.php?json=jsonstring
or would i have to break it down into something like this:
url = /serverside.php?a=1&b=sds&c=sdg
I'm making this ajax call:
Code:
url = "/GeoAdaptaApp/geoLogger/logGuiEvents?json="+aLotOfJSONStuff;
encUrl = encodeURI(url,"UTF-8");
new Ajax.Request(encUrl, {
method: 'get',
onSuccess: this.sendQueueToServerSuccess( this,logConsole ),
[Code]...
The JSON string seems correct (I checked it with a validator) and it worked on an Ajax.updater (but i need a request now). Firefox keeps telling me:
[Code]...
The call always end up in the onFailure block. Full request here: [URL] It's very strange, Is there a better way to pass json objects to the server?
