JQuery :: Retrieve Json_encoded Data But Getting "undefined"?
Jun 2, 2011
have the following code that I thought I could retrieve json_encoded data but I'm just getting "undefined".The json_encoded string from the php array:{"table":null,"id":"2","itemCode":"1003","itemDesc":"Item infor for1003","itemWholesale":"1.99"}]I thought I could "grab" the name of each in the array and output the dataaccordingly. So on success of the ajax post (which does return data) I triedalert(itemData.itemCode); This is on line 10 in the below code snippet. Using this method returns "undefined" and NOT the data 1003 as I would expect.
jQuery Code:
$('#search_results tr').live('click', function() {
var $itemrow = $(this).closest('tr');
[code]....

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'm completely new to jQuery and Javascript but I have extensive (10+ years) with Flash and Actionscript.
I want to create a dyanmic tree menu, but I wonder what is the best way to get the data from a MySql database.
Honestly, compared to AS3, the implementation of XML seems very primitive... In As3 you simply move around the xml as if those were objects using E4X. This way: MyXML.myNode.myChild[3].text()
So I wonder, what is the best way to work with data from the DDBB? Is there a better way of using XML with jQuery? Maybe JSON?
How should I approach this?

I am new to jquery and i have no freaking idea about jquery. One of the requirement is to use Jquery to datastore and dataretrieval so on my aspx page, a user enters a comment and clicks on "Add" button.When user clicks on Add button, I wan to add comments to database. Once data is added to db, I also want to retrieve same data, user name and current datetime as a dataset and show it on the page. How can I achieve this? I am creating a webservice which accepts "comments" as parameter and stores into database.

We are trying to develop an Engineering application using PHP,
Javascript with Informix as the back-end.
Is it possible to retrieve data using Javascript but by accessing the
Database. Say somebody enters part_no, than using Javascript is it
possible to connect to the part master and retrieve the division and
desc information?
I am not allowed to use the PHP because this will require the user to
insert the part number on the first page (user input page) and then
retrieve the information using PHP and display the info on the second
page (processing page).
I will need this to be done on the same page. That means the info will
need to be retrieved instantly (on the fly).
I think of building a javascript array for the part master table using
PHP but finally decided not to as the table is a huge table (contains
more than 1000000 records).

I'm trying to use AJAX to load user's profile through a drop-down list on selected user. There are 3 seperate files:
1) view_info.php
2) selectuser.js
3) getuser.php
I tested and found that the value $q did pass from view_info -> selectuser.js -> getuser.php, and value changes correctly as i select different user from the drop-down list. Problem is, it simply can't fetch data from my database using the value $q. I tried debugging it for 3 hours already and is totally out of idea whats wrong with the script. i'm new to AJAX, this is my first script..

I am having question on how to retrieve data from web page.
There are 'Yes' , 'No' checkbox for different questions on the web page. There are around 50 such questions.
I have to retreive the values submitted by the user by clicking on either Yes or No checkboxes. Then save this data on the server. I have to use Javascript for this.
Since I am new to Javascript I am not getting idea how to implement it.

I'm currently working on a personal site and I'm using a very interesting javascript library written by Jacob from nihilogic.dk. This library allows me to extract some EXIF-data from pictures. My site will serve as a picture site where I will post pictures from my future world trip (one year travel from north america to south america).
My idea is to take pictures with a camera with GPS functionality so all the pictures will be tagged (in the exif) with a latitude and longitude value.
The objective is to post these pictures on my site when I'm on tour and dynamically link them to a google map so visitors and myself can see the exact location where the picture was taken.
The following libraries offered by nihilogic: (binaryajax.js and exif.js) [URL] are able to read EXIF data such as latitude and longitude from the picture.
Since I'm trying to work with jquery I also tried the jquery version which does also read exif data. However the jquery version of the script doesn't read latitude and longitude tags.You can find this script here:jquery.exif.js
My question is it possible to find a solution that will allow reading out the longitude and latitude data with the jquery script? Is it possible to tell me how to enable this data in jquery?
Here's a test sample of my site using this script. click on the little globe icon under the first picture to see google maps and EXIF data.

I wrote this simple snippet to animate a listitem from an unordered list. Here it is:
function OnLoad() {
$('#navigation').mouseover(function() {
$(this).find('li').stop(true, true).effect("pulsate", { times:2 }, 150);
});
So I have a div with id "navigation" which contains an <ul>, and the <ul> has several <li> items.What I want to do is to animate the <li> items as i rollover them.My question is , how can I only animate the current <li> I rollover, because right now when I rollover one, all <li> items animate.

JQuery 1.4. I cannot get this line to return anything but null:
alert($(this).closest("div.cr").html());Any ideas on why not? I have tried using parents("div.cr:first") with no luck as well.

I have a jQuery object upon which I am setting the 'top' value using the .css() method. The value is to Float accuracy:
$('#example').css('top', 13.857759);
Setting the value works fine, and the result in the DOM is:
<div id="example" style="top: 13.857759px;">...</div>
However, when I go to retrieve the value using the .css() method, the value is returned as an integer: alert($('#example').css('top')) // alerts "13px" Is this an intentional quirk of jQuery, or considered to be a bug?
