Compare Incoming JSON Data To The Existing Data?
Sep 9, 2011
I'm trying to compare incoming JSON data to the existing data to see if there are any changes, but for giant objects like:
Code:
[{"date":"2011-09-03 23:06:03","notifier_id":"1","type":"1","unread":"0"},{"date":"2011-09-05 00:37:46"}]
if (JSON.stringify(oldData) == JSON.stringify(newData))
This doesn't seem to work. I've tried using:
Code:
escape("'" + JSON.stringify(W.notification.list + "'"))
but that ignores the objects properties and returns something like 22%5Bobject%20Object%5D%2C%5Bobject

I have just started to learn about JQuery and wanted to learn how to retrieve data from an API.
I used the Flickr example provided here [url] and just changed the relevant code to point to the 500px api.
<body>
If I launch the following URL I do get the results properly [url]
Here's a sample of what the result looks like:-
I don't get any results when I run my code page. What am I doing wrong?

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. The table should be dynamic with previous and next buttons and the table should populate the results according to the JSON and each page should have 20 entries and then the remaining entries should go on the next page and I should be able to go back and forth in the table using previous and next respectively.tell me the exact code of how to start with getting JSON from the API and then write the JSON data in the form of dynamic table with pagination.

My friends and I have developed a chat service that uses Live Profiles to login to chat. The issue I am having is I need to autofill the login page with my email/password to speed up login and I was told JS would be the best way to do it, however, I can't seem to figure out how, lol. I tried sending the login info in a url and bookmarking the url to no avail. The link to the page is below.

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);
});

FYI, I am using jQuery 1.2.3, and the latest version of the jQuery Form plugin from URL...I am able to run the ColdFusion page on the server side to get the data, and Firebug is showing that I'm getting a response...but I'm unable to populate the JSON data into selected form fields on the page.I have two HTML forms; one for the user to input his/her ID number if available, and a longer form to collect more demographic info.Why is it not working? My forehead is getting bloody from banging it against this wall.

I think I have a varialbe scope problem here, but I can't figure it out. What I'm trying to do is extract a piece of data from a JSON file using a variable established earlier in the script as one of the keys.
When I run this script I get the alert that lets me know that the variable "theMappableItem" has been established correctly. I click "OK" in the alert box. Then in my console (in firebug) I see a line showing that the .json file has been gotten successfully. Next in the console is an error that says:

I am new to jquery and JavaScript in general and I want to access data in Google Spreadsheet. So at first I published a spreadsheet to be able to retrieve a JSON feed like mentioned here: Simple example of retrieving JSON feeds from Spreadsheets Data APINow I can get a JSON-File - the specific file is this: My Google Spreadsheet JSON
But I was not able to display any data as of now. My code looks like this:
<!DOCTYPE html>
<html><head>
<title>the title</title>
<script src="[URL]" type="text/javascript"></script>
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery.noConflict(); // probably I need this because in the JSON-feed there are $t-objects
jQuery.getJSON("[URL]", function listEntries(json) {
var content = document.createTextNode(json.feed.entry[2].title.$t);
jQuery("p.inhalt").append(content);
});});
</script></head><body>
<p class="inhalt"></p>
</body></html>
So if this looks like noob-code - it is. How the code should look like if a wanted to access the data in the spreadsheet?

I am working on a servlet. I am obtaining the JSON data and I want to pass it to the jQuery to construct and display the table out of it.
Everytime the servlet posts a request, it gets the JSON data, and i want to display that as a chart and table using javaScript. For that I need to know how to pass the json data parameter to a jQuery from servlet.
Example :
String jsonData = {"key":"value"};
out.println("<input type="button" id="chart" onclick=function(jsonData)>");
Where function(parameter) is the jQuery function.

I'm not sure if this a Picasa thing or a jQuery thing, but I just can't get the following code to work. It works when I type the URL directly into the browser, but not when I do a getJSON call in jQuery:

It's driving me a little insane, and I've not had any response over on the Picasa board at all.

I have a form that asynchronously submits to a PHP file. The PHP file returns the following:
PHP Code:
echo json_encode($array);
In my Console, I see the following:
Response:
{"groupname":"XYZ Group","id":4}
How do I display that JSON code through jQuery code?
Here's the jQuery code I have so far:
Code:
$.post("addgroup.php", { groupname:f.groupname },
function(data){
$("#groups tr:last")
.clone(true)
.insertAfter("#groups tr:last")
.html("<td class='tbldata'>"+ /* Returned JSON data (groupname) */ +"</td><td class='tbldata'> /* Returned JSON data (id) */ </td>");
