Ajax :: How To Send Json Object

Feb 15, 2012

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.

Send Json As Ajax Request To Server

Aug 14, 2007

whats the best way to pass a json string to the server.

if my jsonstring = {a:Ƈ',b:'sds',c:'sdg'}

could i send that to the server passing it as 1 variable like so:
url = /serverside.php?json=jsonstring

or would i have to break it down into something like this:
url = /serverside.php?a=1&b=sds&c=sdg

JQuery :: Ajax: Send JSON Receive HTML?

Aug 15, 2011

I have a web service that accepts application/json but returns HTML to place in a DIV. I am not having any luck configuring the .ajax call so that it both POSTs in a format accepted by the web service and does not attempt to validate the HTML response as JSON.

[Code]...

It would seem that I cannot have anything other than 'json' in the dataType, even though from the docs it appears that this only affects the interpretation of the response, changing it's value to 'html' causes the web service to reject the call. I've also tried a converter but perhaps I'm not using it properly. Is it possible to use jquery to post JSON and get back HTML? What configurations am I missing?

JSON.stringify() Acceptable - Send All Of The Data From These Objects To PHP

Apr 27, 2010

I'm working on a very Javascript heavy application, and we've set up a number of different Objects to handle the data on the page. Very often, we'll need to send all of the data from these objects to PHP. Right now, we're using JSON.stringify. Are there any issues with this? It seem's like it does exactly what we need, but are there any downsides?

JQuery :: Receiving And Alert With [object Object] When It Should Be Alert The JSON Data

JQuery :: Send Array Object Using Get Method

Dec 24, 2011

I'm trying to send my array object through ajax using the jQuery .get method, but when it sends, ids show up as multiple parameters and I'm not sure if that's the way to do it.

Here is my code:
var val = [];
$(':checkbox:checked').each(function(i){
val[i] = $(this).attr('id').substring(6);
});
$.get("/assets/ajax/pm_change_status.php", { s: sess_id(), 'ids[]': val } );

$searchResponse['verificationLists'] = $verificationListsResponse;
print json_encode($searchResponse);

Json Object Size?

Jul 3, 2007

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...

JQuery :: Convert Object To JSON

Aug 14, 2009

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]..

JSON Appears To Be Reordering Object?

Jan 15, 2011

I 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...

Sorting A JSON Object On Different Keys?

May 29, 2009

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.

JQuery :: How To Pass Object In JSON That Is Not String

Feb 3, 2011

I'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?
