JQuery :: Testing For Error Condition In Returned JSON Formatted Data
Dec 14, 2010I'm pretty new to jQuery and I'm using $.getJSON to submit some data to a PHP script which either returns 5 sets of json-formatted data or data to indicate an error condition (i.e., no data available) from the PHP database query. The callback routine handles the 5 sets of json-formatted data just fine (using $.each...) but I'm having trouble testing for either just a string with 'null' in it or a json-formatted data return of [{"error":"null"}].
My callback code for the second approach looks like this:
function handle_stores(data) {
if (data.error == "null") .....
But this test does not execute the following code for the 'true' condition, i.e., data.error == "null" never evaluates to 'true'.
View - Manipulate A JSON File?
Oct 12, 2010I'm working on a research project and a research partner has provided me with a massive file with data I need to be able to analyze from his website (which aggregates the data I'm interested in from internet sources). I've tried importing the .JSON file into excel, but it's awkward and figuring out an effective way to delineate the data has proven nearly impossible (for example, using ':' doesn't work because in one of the fields I need to study, colons appear, so mid-data field it gets cut-off). Is there any program, technique, or converter to take the JSON file and organize the data into something resembling a spreadsheet?
My ultimate destination/goal: I need to sample the data, but only for a couple variables (or I guess I should say fields as in JSON format/lingo each variable contains a couple fields of interest that I need to compare with similar fields from different variables as well as a number of null values/fields), for my data analysis. I need to get the data into some sort of spreadsheet-type format or something that is visually, if not functionally, similar that would allow me to figure out how many datapoints I have in the relevant categories and to randomly sample them. So, to summarize, is there any way to transform the tree-like json file into something column/row oriented automatically, because the JSON file is 35mb, and there's no way I could organize/extract the data I need by hand?

View 1 Replies View RelatedJQuery :: How To Manipulate Xml Data
Jun 23, 2009I'm having some real difficulty figuring out how to manipulate xml data with jquery. Here is my situation. I have a hidden TextArea that contains xml data, something like this:
<items>
<item value='1' text='x'></item>
<item value='2' text='y'></item>
</items>
So, let's say I want to remove the item with value='1'.
1) I grab the value of the textarea:
var xml = $("#" + id).val();
2) I then find the node and remove it:
$(xml).find("item[value='123']").remove();
Problem is, it doesn't remove anything! It finds the node just fine,but the remove() function doesn't seem like it is doing anything. I've tried looping through eacy item $('item',xml).each(function.... ); and
then calling remove(); but that does not work either.

JQuery :: Load Html And Loop Through Json While Changing Html With Json Data?
Sep 11, 2010I 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);
});

Compare Incoming JSON Data To The Existing Data?
Sep 9, 2011I'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
JSON Data Will Not Process
Nov 3, 2009FYI, 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.

May 4, 2010I 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.

JQuery :: How To Get Data From Google Spreadsheet JSON
Nov 2, 2010I 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?

JQuery :: Passing The JSON Data From Servlet?
Dec 30, 2011I 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.
