I have created a JSON object through a PHP script. The code is as follows:
$result1 = array();
$i = 0;
hile($row = $result->fetch_assoc()) // $result contains result from a database query

How to work with nested JSON object/Arrays using jQuery Data Link?
http:[ur]....
I'm just starting to pick up on jQuery and I'm a bit stuck.What I am trying to do is take the following XML response and obtain the src attribute from each image. I then want to append that value to an array.
XML
Code XML:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
[code]....
I realize this is probably one of the most common uses of JSON, but I'm hitting my js knowledge limit. I want to output a two-level <ul> using a json structure.How should I structure the json and then how to output it?Desired output:
<ul>
<li>Topic 1
<ul>
[code]....
The scenario is : I have to fire an ajax request, get the json values and populate the page using jQuery template.
I'm able to fire the ajax request and in the success function I'm getting the data also. But I'm not sure how do I proceed with the Nested JSON data that I have received. I am passing it to the .tmpl() function but nothing seems to be working.
Here is the json data that I receive :
{
"activity": {
"date": [
{
[Code]....
It also gives me an error sometimes that says "c.tmpl is not a function" which is linked to the jquery.tmpl.min.js .
Right now I am pulling down a JSON file with this format (trimmed it down as to not flood the board):
{
"data_types": [
{
[code]....
I'm writing a program that involves a network of interconnected nodes (or simply objects in my example below). It depends on being able to access properties of an object's linked objects (a bit oddly worded, sorry)...Problem is I'm not sure how to properly access those properties... see below please.
<script>
//This is an example of a problem im having in my own code...
//I want to access the name of the object within the links array wintin the object...
[code]....
jquery code:
$.ajax({
url: "validate_livestock_form/index/",
type: 'POST',
dataType: "json",
data: form_data,
success: function(data) {
alert(data);
[Code]...
php page is echoing out:{"species":"Please select a species!"} I double checked the response from the php and firebug shows the same. On success alert is not alerting the JSON data instead, I'm receiving [object Object]. Why is that and how do what should I do to fix this?
I am trying to convert a very simple JS object as follows to JSON, cant seem to find the solution [code]...

In addition to fetching JSON you might want to POST it back to the server, but there is no postJSON method. You cannot use the generic ajax method, either. What is missing is the complement of "eval" to turn a JavaScript object in to JSON. The JSON.stringify function from www.json.org (see json2.js in JavaScript section) does the trick, but it would be nice if jQuery incorporated that out of the box, to save some hunting time.
Using the jquery ajax method to set the "type" to "json" and the "content-type" to "application/json" send and recieve JSON, but you must use JSON.stringify to convert your outgoing object to JSON. P.S.. a lot of forgiving parsers have resulted in a lot of articles on JSON being wrong. would I like to mention that here. Property names are JSON strings. JSON strings have double quotes. Therefore, property names have to be surrounded with double quotes. Single quotes are not JSON strings and not legal (JSON is not JavaScript).
[Code]..
Supposed that I have a json object but I don't know anything about its keys and values. Is there anyway to print out all the key and value pairs in that object?
View 5 Replies View RelatedDo any of you know if you can convert a JSON object into a Jquery object ? The reason i wish to do that is to be able to use the jquery selector to filter my Json data. (for example filter them based on their properties)

View 1 Replies View RelatedI'm a beginner in Jquery and I have a big doubt, follow at bellow the code to be better viewed: The method below is static and Static methods do not work with instance, For this reason I passed the 'nameLabel' that the typeis Label by parameter, however I need to catch the exception and show it to the user.
[WebMethod]
public static string RetornaNomeCliente(string idCliente,Label nomeLabel){
string nomeCliente = String.Empty;
try {
nomeCliente = Cliente.RetornaNomeCliente(idCliente);
} catch (Exception e) {
nomeLabel.Text = e.Message.ToString();
} return nomeCliente;
}
But I'm using Jquery and this method is used in a Ajax Request and I use the Json to pass the datas, how showed below:
var idCliente= $("#<%= txtIDCliente.ClientID %>").val();
var nomeLabel = $("#<%= lblMensagem.ClientID %>");
var poligonal = "{ idCliente: " + idCliente + ", + lblMensagem: " + nomeLabel + " }";
But the problem is that I need to pass in my Json the nomeLabel with Label, but always a problem happen, because the same is showed like 'indefined'. How to solve this situation?
With this JSON object as an example:
jsonObj={
key1: 'value for key1',
nextKey: 'nextKey value',
lastKey: 'value for the last Key' };
without knowing the structure of this object... is there a way to return the name of the keys?if it was a nested aray.. each key:value pair being a 2 element array I could do something like this:
var key = jsonObj[1][0]; // this would return 'nextKey'
Is there some way to determine the names of the keys ina json object, as if it was an associative array?
I would like to redirect my request from a page to another one with a json object. The only way i have found to do this is :
[Code]...
Is there a way to do this without using .Ajax ? With this method i have to save my json object in my session to reuse it after and i don't like that !
I've got the following code:

I was just wondering how will I be able to access the content of the data variable in script.template.php?
The other problem is that when I use the $.getJSON method (instead of just $.get), the script doesn't appear to get called.
I have a very simple PHP script that returns JSON like this:
{"question":"What day is it?"}
And I'm trying to call it from another page using Ajax. My code looks like this:
var url = "/test.php";
$.get(url,
function(data){
$.each(data, function(i, value) {
alert(value);
}, "json"
);
});
When I run it I get each character printed out one at a time in a separate alert. And then when I used this line of code:
alert(typeof data);
It tells me that 'data' is a string. Shouldn't it be a JSON object?
I've started using the gMap plugin [URL] in my site
I have a div, with id "map" in my code and I am creating the map with the following code, passing in a JSON object for config:
$(function() {
$("#map").gMap({
latitude: 54.7,
longitude: -4,
[Code]....
I want to programatically re-center the map and add markers elsewhere in my code, but don't know how to access this JSON object to modify it.
The way I'm currently doing this is to call gMap again with some new configuration, but I don't think this is right as I think it's re-creating the map all over again.
How might I go about getting the parsed JSON object in the complete function? The json param shown below seems to just receive the http status text message.
My 2nd question would be how should I knwo if the first place what params I can receive to a callback function like this?
$.ajax({
type: 'POST',
url: 'url.json',
dataType: 'json',
[Code].....
Is there a Jquery method I could use to quickly parse a JSONP object, looking for an embedded object called "error" ?? If I were to do the following:
jQuery.each(query.data.error, function(i,error){ //....}
And there wasNO .error in the returned JSON, what should I expect to happen? Basically, I want to know if "error" is in the JSON and process accordingly.
The below code posts a couple of vars to a php file which sends back a json object containing (in the test case) one object called 'faves' with 2 variables (let's say called var1 and var2). I can't seem to access the variables after the ajax call. The result is always an 'undefined' error message. I've tried:
console.log(data.var1)console.log(data.faves.var1)
console.log(var1)
All to no avail. Can anyone tell me what I'm doing wrong here? I have checked with FireBug that all the data returned is good and well-formed etc.
$(function() {
$.post("<? echo base_url(); ?>test.php", {
id: "<?php echo $id; ?>",

I tried to pass the external JSON object on validate method. But It's not working.
