JQuery :: Get Encoded JSON Items?
Apr 30, 2010
I am having quite a bit of trouble getting items out of a json encoded array. I have searched this forum tirelessly and can't find anything except more confusion. I'm simply trying to retrieve data from a mysql db via ajax.
select.php:
echo $json_encode_data;
output is like so:
{
[Code]....
Do you need to use a .json file when using .getJSON? I simply want to print data from my select.php file that has an json encoded array. If there is a more simple way to do this without using json encode

I have a select field. I must fill with options taken from a mysql table.Here is some little php code I have done using codeigniter framework
$idcateg = trim($this->input->post('idcategory'));
$array1 = array(
'result' => $idcateg
);
echo json_encode($array1);
Now, the jQuery call...
$.post("<?=base_url()?>index.php/rubro/list_ajax/", {
'idcategory' : idc },
function(data){
[code]....
The code works fine. When I call the post, I get the categoryid as a result.Now, I should modify the code above, so I can do:post the ajax call sending the category id. this is done get subcategories for this category, and build the array * json_encode the array and echo * get results back in jQuery ajax call, decode and build the < select > field *The array should be built with each element having a sub-array with id and name, right?

My data (that does not need to be secure) is stored in a json array. If I include the file [2nd block below] in the head of my page with:
Code:
<script type="text/javascript src="list.js">
And my json object "list.js" looks like this:
Code:
var a = {"b": [
{
"cfirst": "0",
"csecond": "y2",
[code]...
What code would I use to reference the text "r3" if I knew "q2"?

I have an image that is encoded as a base 64 string, and I'm having trouble passing that a WCF service using $.ajax(). I initally tried using JSON to pass the argument to the web service, but I kept getting 400 Bad Request errors for anything of reasonable length (if I just pass a test string in, it makes it through, of course). I've tried calling encodeURIComponent on the string before stringifying it, but that hasn't helped. I've also tried various content types ("application/json; charset=utf-8", as well as whatever the default is) and that hasn't made a difference either. Unfortunately, the request is being made through a mobile phone, so debugging options are few. Is there an upper limit to the size of the argument that I'm passing in this? The strings can be a few hundred kb at the low end up to maybe 1 or 2 mb at the high end.
Here is a snippet of the code I am using:
$.ajax({
type: "POST",
url: "http://www.myserver.com/MyService.svc/MyFunction",
cache: false,
[Code]....
No matter what the string consists of, it errors would with a 400 Bad Request error. No further information.

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);
});

I have an ASP.net page where I load a record set server side and upload it into a listbox. I'm trying to do all the movement functionalities of the listbox items client side. Specifically, I'm trying to figure out how to copy selected listbox items from one listbox to another -- on button click. I've searched for a while, but every example that I found moves the actual item into another listbox, I just want to copy the selected item to another listbox.

I'm having trouble with a plugin system that I'm working on. It involves binding a doubleclick with two elements that have the same id. The two elements are different plugins, and load appropriately, however the dblclick binding seems to not change between elements. Here's my code(simplified):
$("div.editor").droppable({
drop: function(event,ui) {
objID = ui.draggable.attr("objID");
$.getJSON("objects/"+objID+"/object.json", function(data) {

I have multiple ul with multiple actions on 'button' changes, i.e.:
<ul>
<li></li>
<li></li>
<li></li>
<li></li> <--this is to be hidden
</ul>
[Code]...
The UL's are to show top 3 items let's say, and hide the rest. When items are hidden on page load [top 3], the Show button is on. When that is clicked, it shows all LI's for that UL and button/link text changes to Hide, and hides all other items of all other items of other UL's apart from their top 3 items.
When the items show, and the text/image is changed to Hide, hide's on click should also hide that UL's items and only show three items for that UL. 3 items are always shown.

I am trying to put the finishing touches on my client's website. The site was built with Wordpress as its CMS. For the site's 'Photos' page, I used the NextGen Gallery plugin to manage and display the image gallery. We (my programmer) made some modifcations to the plugin so that users could upload images from the frontend of the site. That was no problem.
Then I added a jQuery script that toggles each image's description text OFF and ON. It looks good on the 1st page of the gallery, but then if you click to page "2" you get taken to a screen that shows all the descriptions toggled ON. I don't know what's doing it, but something is causing all of these descriptions to show at once, which is NOT what we want.
Here's the jQuery script I am using (it's in no-conflict mode so it plays nicely with the other code libraries in wordpress):
Code:
var $j = jQuery.noConflict();
$j(function(){
$j(document).ready(function( ) {
[code]....
how I can make a 'description text box' disappear/fadeout when another one gets clicked? Right now you actually have to go back and re-click each one before it toggles OFF, which starts looking terrible after you've clicked a few of them.

I want to compare the total number of checkboxes with the number of checked checkboxes of a certain nameI use these 2 functions:
alert($('input[name=checkItem]').length); // To get the total count
alert($('input[name=checkItem]:selected').length); //To get the total selected count
The first one works, the second one doesn't.
