View 2 RepliesHi, i'm creating my own image gallery using jQuery, and there is a set of thumbnails at the bottom. The thumbnails have been put into an array, using jQuery, but what i am trying to do is to return the position of any clicked thumbnail in that array. i.e. when the 3rd thumbnail in the list is clicked, return 3, when the 5th thumbnail is clicked return 5 etc....
This in turn will dictate which item in another array (the main images array) will be displayed.
Is there a best way to reorder a jquery group/array, eg bring one item to the first position? Should you do it with a normal array.sort() or splice(), or is it possible with an internal function map()?

I have a page where there is a list of items and a drop container. When I drag item, the other items below the one that is being dragged moves up. Can other items stay in their respective positions when one of the item is dragged away?I have list of items like this:
<ul id="allItems">
<li id="node1" groupId="box2"><img src="nmm_logo.png" height=70 width=130 align="left""></img></li>

in jCarousel i have a list of items, what i would like to be able to do is when the user clicks on an item (say the 4th visible item in the list) the carousel would scroll so that the clicked item becomes the first visible item in the list.

I'm trying to grab values from a set of arrays based on the value returned by my select box.
**Caveat - this is not an area I have any real experience with**
My arrays look like:
Code JavaScript:
I then need to test for each, then associate with one of my fees arrays, then grab each of the values in the array and write those values to elements within my page.
I'm then doing this to evaluate for each degree
Code JavaScript:
I need to first figure out how best to import all of these 60+ arrays and then in each of my conditions pull out each value and write to my page.
There is a unique 1 to 1 relationship between each degree and array so I can't consolidate as the values for each degree differ slightly.
I have something like this:

I have a question about removing an item from an array.I am looking to remove an item from the array based on the property.Ie.arr = [{a1: 1, a2: 2},{a1: 3, a2: 4}, {a1: 5, a2: 6}]remove first item from array because a1 = 1.I am not entirely sure how to do this. I tried messing around withgrep a bit, but that didn't turn out well.

$("div#carousel a").each(function(i) {
$(this).click(function(e) {
e.preventDefault();
console.log(myArray[i]);

it doesn't loop, it always prints the first item in the array (there are 18 <a>'s inside div#carousel, and 18 items in the array...)
I have an unordered list that I am using as a menu. This list contains sub lists.
I found out how to get the index of the primary unordered list item that is being hovered but I am not getting the syntax correct to reference the individual items of this listto get the HTML, the position, height and lengthof this item.
$(" #nav li").hover(function(){
// Locate the index of the singular list item that is being hovered
var index = $(this).parent().children('li').index(this);
// This is incorrect
var $itemObject = $(this).parent().children('li')[index];
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 writing this code
<script type="text/javascript">
$(document).ready(function() {
var obj = jQuery.parseJSON('{"a":"sss","b":"sss","question":"whi?"}');
//alert(obj.question);
});
</script>
How could I know how many objects variable obj has?
Your table-driven application has a MySQL table on the server side and you want a Javascript associative array on the client side to do rapid look-ups.For example: My application uses the value selected from the form’s drop-down menu to choose which other form fields to hide or show. This choice of a 'Long Form' is table-driven from product data in a MySQL table.
Convert the MySQL table to an associative array in JavaScript.I am using the jQuery library to manage the presentation and form validation on the client side and PHP and MySQL on the server side.Since a JavaScript Object is an associative array and the MySQL table is being used as a look-up table (associative array) I use the PHP function json_encode to create a JSON string - JSON is JavaScript Object Notation - on the server which is then evaluated as a JavaScript Object on the client. The two parts (server and client) of the code are listed below.All very straightforward then. So why the blog?This is what I do (here's the PHP code):
do { $key = $row['ProductKind'];
$value = ($row['LongForm'] ? True : False);
$arr[$key] = $value;
[code]...
As a newcomer to jQuery this is a good opportunity to show my appreciation to John Resig and the people that have contributed to the jQuery library ... not forgetting those who have integrated all the MySQL and JSON stuff into PHP. It's all very neat ... when you get to understand it!You could just eval(data) to turn the JSON string into a JavaScript Object (a.k.a. associative array), but JSON.parse protects your code against evaluating malicious scripts that could be embedded in the JSON string. This function is found in the json2.js downloadable until included in native browser JavaScript engines.The PHP Booleans translate automatically into JavaScript Boolean types.
[Skip this: My application has a MySQL table of product categories that tell me whether I need to present the administrator with a long form or a short form in the HTML. So, as products are added over time, I want to the administrator to choose whether a new product category can take the short form plus some default values or will require the explicit input of all product values in the long form. As the administrator assigns a category to a new product - and changes his mind half a dozen times - I don’t want to keep on going to the server to do the look-up but want to have the table in Javascript to keep the form presentation responsive. Also, the MySQL tables are on a third party’s server remote from the web server.]
I'm trying to assign the values from the JSON data returned when I run this code into an array that's outside the callback function. The data is multidimensional, and I have been able to use this data within the callback function. However I want to use it outside that function. i.e. the jsdata returned in the code below is to be used outside the function
Code:
$.getJSON('../fxns/status.php',function(jsdata){
//do some stuff with JSON data or pass to global variable[code]..........
I am doing a password reset form using Jquery and PHP. If I try to submit an email id it should sent and email and report back the response text as success so that the user knows email has been sent. But I am stuck with JSON submit as I have an empty array to decode at the serverside. I am using minified version of json2.js from the official json.org website
Here is the code.
Code JavaScript:
var formdata = $("#log-box").serializeArray();
formdata = JSON.stringify(formdata);
var notifymsg;
alert(formdata);
$.ajax({
type: "POST",
url: "forgot-pass.php",
contentType: 'application/json',
data: formdata,
success: function(responsedata){
var some = responsedata.split("&");
$.each(some, function(index,value){
//alert("index="+index+"value="+value);
});
},
error: function(o, s, e){
alert("Form not posted
"+e);
}});
formdata alerted gives:
[{"name":"email","value":"ravi.k@gmail.com"},{"name":"acctype","value":"loginaccount"}]
PHP forgot-pass.php
Code PHP:
print_r($_POST);
Gives
Array(
)
is it possible to access the index of the json data array in the current iteration and use it in a template?

I was wondering if there is a way to combine both in one in Javascript.
