I can't edit how the response comes to me.

I got a problem with a json response from an ajax request.
I have the following code :
Code:
And the called page (ajax_sous_famille.php) is giving me this result :
Code:
The info in the resulting string is correct, but here you can see the [ ] at the start and end of the line. It seems not to be a correct Json string and then it crashes my script !
I have another request like this which gives me the good format of resulting data (without the [ ]) and which works perfectly when i decode the Json string to display it.
The difference between the 2 requests is that the one which works returns only 1 array of values like
Code:
And the second one which doesn't work returns something like
Code:
Actually, all the records are coming from a database and in the case it doesn't work, i wanna get several results from this database.
I'm having a tough time getting at the values I want in this ajax response. Here is the response

I'm trying to get the value of the "site_id" and the "display_name" column but I can't get it right.
How I can convert a string to a json array.

The problem is that .css treats snip[1] as a string but I need it to handle it as a json array.
Bad: .css
Good: .css
I have an ajax post which returns a large html response. It is getting truncated at 98784 characters everytime. Is there a limit to a response size or a way around this?

Here is my ajax call:
I want to access a web service and get the response in json using javascript. The web services can respond in json and gives me a table of records with a specific campus. I input the campus code in the text box and create the url. Now, I want to get the response in json and I'm really stuck.
<FORM NAME="myform" ACTION="" METHOD="GET">Enter something in the box: <BR>
<INPUT TYPE="text" NAME="inputbox" VALUE=""><P>
<INPUT TYPE="button" NAME="button" Value="Click" onClick="loadurl(this.form)">
</FORM>

From the information search process: I know I have to change the HTTP Header accept and use application/json and probably use JSONRequest.get()
I've been hitting a strange bug where callbacks are not invoked when a JSON response is returned from an AJAX call under jQuery 1.4.1. I just upgraded my app; this was working perfectly pre-1.4.
I do specify the return type as "json" when I invoke $.post . When a simple JSON string like "false" is returned, the callback is invoked. It seems to fail with more complex types, specifically with JSON objects, i.e., {"a":1, "b":5} .
If it helps, I'm running Firefox 3.5 on Ubuntu. In my test environment, the only installed extension is Firebug.
How can I adequately parse a JSON response I'm getting from the server, which happens to be an array?
The array I'm getting back is actually this one:
[{"photo":{"created_at":"2011-02-26T18:40:00Z","id":5,"name":"Natalie_Portman.jpg","updated_at":"2011-02-26T18:40:00Z"}},{"photo":{"created_at":"2011-02-26T18:40:14Z","id":6,"name":"scarlett-johansson-.jpg","updated_at":"2011-02-26T18:40:14Z"}}]
I believe this one is valid JSON, but my attempts to parse it are always failing when I do it like this:
success:
function(data, textStatus, xhr)
{
var photos = jQuery.parseJSON(data);
alert(photos);
},
The above code displays 'null', and the documentation says a null occurs when the JSON isn't valid. so, what's going on ?
I need to know the codes to parse as well as access the values in the parsed response.
I have a file upload form (see end of email) that I am am processing with jQuery so that it can be submitted via AJAX. When I click the submit button, the form sends as it should (I can see the submit went properly in the server logs). However, the response doesn't get handled properly. In the response, I get a file download dialog (firefox), although the page itself isn't replaced: "You have chosen to download

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).

I have already set the Content-Type header of the response to application/json, which made no difference. I also tried text/html and text/plain, but in these cases Internet Explorer shows the JSON as HTML or plain text in the browser window... *sigh*
Googling also gave me the suggestion to just use text/plain and eval() the response myself, but I remember reading elsewhere that this is pretty unsafe. I am unsure on the specifics on this, though.

Some servers return JavaScript as the response to an AJAX request. When
the response JavaScript is eval'ed it calls other JavaScript functions
already in the browser to update elements, etc. This seems like a good
system because it allows so much freedom in creating the desired
behavior in the browser. The required data doesn't have to be converted
to XML or JSON on the server. The browser doesn't have to have
templates for interpreting and converting this data into some change in
the browser. All of the conversion algorithms don't have to be written
and changed when new behavior is required. This remote procedure call
approach is the predominant system in the Ruby on Rails world.
(Unfortunately they are calling Prototype.js functions.)
However apparently some people seem to think this remote procedure call
approach is a bad idea. I can't see why it is so bad because it is so
lightweight and flexible. It also helps to keep the client less
intellegent which seems good in a world of incompatible client-side
bugs.
If I use some neutral data format like XML to accomdate different types
of clients then I have to write different client-side interpreters for
each type of client (browser, RSS, POP, cell phone, etc). Why not just
write different server-side code that generates the correct JavaScript
(or other) for the requesting client type?
When is the RPC approach such a bad idea?
I am using ajax / php where I am looking up some info from the
database and populating a select list dynamically, however I am
running into some sort of size limitation with the ajax.response
object. If the string I am passing to javascript from php is too large
javascript does not get it all the data. The magic number appears to
be 6123 characters, anything below that it works fine, anything above
and if I alert the ajax.response, I see the string is cutoff. Any
ideas where this limitation is defined?
I am using following code
Now what i want to do is: i have a callajax() function. with in this function i will call do_login() function. this do_login() handles an ajaxrequest and returns the responsetext.
Now i want to do some validation on this responsetext(in case of onsuccess). so i am trying to return value to callajax() function for onSuccess case in ajaxrequest.submit();
That is(onsuccess response) supposed to be some string( but not true or false). but i am always getting false in ajaxcall() function. i know the do_login() function is returning false before ajaxrequest completes
So i want to stop this and make do_login wait until ajaxrequest completes and then i want to return it's response to callajax() function.
I am wondering how possible it is to use eval() to parse javascrpt that is pulled in through ajax(innerHTML)? I have found a few notes about this, such as:
Code:
var myObj = eval ( xmlhttp.responseText );
