Ihave a Json Object n wanna select one row based on id and name
[Code]...
so, the pseudo code: - on change of input contents, check to see if two input fields are set - if set, update a third field with "loading..." text and a loading gif - use ajax to send data to a url, and get a calculated json response - update the third field with the calculated response
I know I'm getting the correct response, according to firebug: {"pace":"10:00"}
the code:
$('#run_distance').change(function() {
if ($(this).val() != '' && $('#run_time').val() != '')
{
$('#run_pace').val('Calculating Paceā¦');
[Code].....
how to update the #run_pace input field with the json response.

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?
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 have set up a pretty nice page with moveable layers and everything. Now I'm stuck in the very last part, how to open a popup!
Basically I have a div-layer with three events: onmousedown, onmousemove, onmouseup and ondblclick. The last one should be for opening a big image of the small thumbnail in the layer.
So what I've got yet is this:
function Oeffnen(id) {
var url = "bilder/"+window.document.images[id]+".jpg";
testwindow = window.open(url, "bild", "resizable=yes,menubar=no,scrollbars=no,toolbar=no,status=no,screenX=50,screen Y=50");
}
it's the "var url" part which is giving me headaches. The thumbnail is say /thumbs/img1.jpg. On double-click it's supposed to open a new window containing /pictures/img1.jpg. Not really difficult, but I just can't figure out how to get the "img1.jpg" part! id is the name of the div-layer.
So what am I doing wrong here?
I am trying to convert a very simple JS object as follows to JSON, cant seem to find the solution [code]...
View 1 Replies View RelatedIn 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 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
[code]....
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 have this code that load HTML tags (no including <html> or <body>)
into a DIV dinamically...
after correctly retrieving the HTML, I assign it to my DIV Container
document.getElementById(containerid).innerHTML=pag e_request.responseText
now from main page....I need to get a reference to an Object (a
textbox) contained in the dinamically loaded HTML
Once in my main document this, doesn't works:
document.getElementById(containerid)
The objects that I loaded dinamically, are part of the Main Document or
not? How can I access this objects from my main page?
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; ?>",

How to work with nested JSON object/Arrays using jQuery Data Link?
http:[ur]....
I tried to pass the external JSON object on validate method. But It's not working.
Here is my sample code:
I have an array of HTML tables created in PHP which I send as a XMLHttpResponse encoded with JSON. Is there was a way I could access the table elements which are now in the JSON Object?
Relevant bits:
PHP code:
$verificationListsResponse = array("classeList" => "$classeList", "workCodeList" => "$workCodeList");
$searchResponse['verificationLists'] = $verificationListsResponse;
print json_encode($searchResponse);
