I have such problem when I post my object from client to server (php).
The object should be like so:
Code:
I converti it:

And send it though jquery and ajax:
property val is the object...
Then on side of server I gota string $_POST["val"]:

I try to convert it:

I'm currently constructing a javascript "terminal" on a site I'm building so that I can test objects and functions outside of the web developer terminal in google chrome.
Given that I have active javascript defining an object called item, typing item in the chrome terminal returns Object and goes on to list the properties of item.
Moreover, I can define a function in the terminal like this: function(x) { return x }, and then function(item) will return Object and list the properties. However, if I use form data and user input in the place of the argument, the datatype becomes a string and not an object, so typing item in the form and clicking a button that performs function(document.form.text.value) returns the string item and not Object.
Is there any way to convert this primitive string to an object so that I can then iterate through properties, and so on?
How can I avoid type-conversion (object variable --> string) when
passing an object variable to a function?
Example:
-->
catch(myerrorobject)
alert(myerrorobject.filename);
{
my_function('bla: ',myerrorobject);
}
<---
I get the "myerrorobject.filename" in the alert-Box, but I get an
"undefined"-error, if I try to access myerrorobject.filename (or other
properties) in the function "my_function". Why?
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 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);

Does anyone know the function for adding more items to an already declared JSON object?
Assuming you have something like code...
i have this user interface for a client that i have to mod (The UI is a link crawling monitoring for his website), the present one uses php database connection for every single action that is done on the UI (select link to be monitored, show link stats etc...) what we want to do is to have the links retrived from the database stored in a json object while the client is playing with the links on the UI (making all kind of editing actions) and then when he want to store all the modifications/actions he has made then the data stored in the object are sent back to the database...
One of my coworker's (he's a java and O.O. programming specialist) objection to that is that there are too many links (data) to put in a simple Json object... and it will be then difficult to store all the actions made on the json object because there will be too many info/data for it to handle etc...
The JSON object I am using is as below . this object is returned after an AJAX call
{"application" :[
{optionValue:"101", optionDisplay: "estmt"},
{optionValue:"11", optionDisplay: "Arif"},
{optionValue:"12", optionDisplay: "JC"}
]}
In the JS i am using the below code
data = ajaxRequest.responseText ;
var jsonOBJ = eval('(' + data + ')');
len = jsonOBJ.application.length ;
key = jsonOBJ.application[i].optionValue ;
value = jsonOBJ.application[i].optionDisplay ;
Internet Explorer is able to process the above code , but while trying
from Firefox , I am getting the below error message
jsonOBJ has no properties
[Break on this error] len = jsonOBJ.application.length ;

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).

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 RelatedI have a PHP file that pulls down data from a MySQL database, filtered based on a tag ID. That data is then returned using PHP's json_encode function to the client where it is translated back using JSON's JSON.parse function. Seems to work absolutely great! Except... it seems to reorder my object completely by itself...
Here's an example:
When my query ends with ORDER BY posts.postid ASC, I get the following JSON:
Code:
{"type":"tags_posts","tagname":"json sort test","posts":{"100":{"reltags":{"201":"json sort test"},"subject":"JSON Sort Test 1","message":"JSON Sort Test 1","posteddatetime":"2011-01-15 07:25:34","authorid":"1","authorname":"azcn2503","commentscount":0,"postedip":"193.132.232.210","postedipgeo":"GB"},"101":{"reltags":{"202":"json sort
[Code]....
As you can see, it has been reordered somehow and looks exactly the same as when it is ordered ASC.
Is there something in the JSON file that I just can't see? I've been coding for a while now and could be going blind...
I am passing some equity option contract data from my PHP processing page to the UI. I am attempting to use the JSON response to populate a matrix. Along the far right column are the strike prices (22, 23, 24, 25, 26, etc) and along the top row are the expiration dates (Jun 2008, Jul 2008, Aug 2008, etc.). My struggle is how to match the option data to the correct strike and expiration date. An example of the JSON response is below:
Code:
{"calls":
[
{"row_id":119,"type":"call","expiration":"JUN 20, 2009","t1":22,"strike":"25.00","symbol":"JSAFE"},
{"row_id":127,"type":"call","expiration":"JUN 20, 2009","t1":22,"strike":"26.00","symbol":"JSAFI"},
[code]....
Would be a JSON returned object that has all the option prices for all the expirations as properties.
Im having difficulty getting my form contents to send to my php page using ajax, jquery and json. The results just doesnt want to show.

var JSONobj;
var JSONstr;
function createJSON(){

What should happen is the firstname should be alerted. But the alert box doesnt even show and I find no errors using firebug...
I receive a response from an ajax call and I need to load the response into a Json structure like so:
Code:
var data = { "products": [
{" longitude": 151.6838460, "latitude": -33.0086640}
,
{"longitude": 151.4008410, "latitude": -33.4728590}
[Code]....
Do 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'm trying to put a function in a object created using JSON notation. The syntax looks like this...
Code:
historySet = { ajaxRunFunction: "updatePageCopy('" + pageID + "','','" + pageName + "')"};
It works fine in FF, but in IE it calls the function updatePageCopy when it creates the object history set. I don't want to call the function when the object is created.
