JQuery :: Parse A JSON Response Array?

Feb 26, 2011

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.

JQuery :: MySQL PHP Associative Array To Via JSON?

Jun 5, 2009

Your table-driven application has a MySQL table on the server side and you want a Javascript associative array on the client side to do rapid look-ups.For example: My application uses the value selected from the form’s drop-down menu to choose which other form fields to hide or show. This choice of a 'Long Form' is table-driven from product data in a MySQL table.

Convert the MySQL table to an associative array in JavaScript.I am using the jQuery library to manage the presentation and form validation on the client side and PHP and MySQL on the server side.Since a JavaScript Object is an associative array and the MySQL table is being used as a look-up table (associative array) I use the PHP function json_encode to create a JSON string - JSON is JavaScript Object Notation - on the server which is then evaluated as a JavaScript Object on the client. The two parts (server and client) of the code are listed below.All very straightforward then. So why the blog?This is what I do (here's the PHP code):

do { $key = $row['ProductKind'];
$value = ($row['LongForm'] ? True : False);
$arr[$key] = $value;

[code]...

As a newcomer to jQuery this is a good opportunity to show my appreciation to John Resig and the people that have contributed to the jQuery library ... not forgetting those who have integrated all the MySQL and JSON stuff into PHP. It's all very neat ... when you get to understand it!You could just eval(data) to turn the JSON string into a JavaScript Object (a.k.a. associative array), but JSON.parse protects your code against evaluating malicious scripts that could be embedded in the JSON string. This function is found in the json2.js downloadable until included in native browser JavaScript engines.The PHP Booleans translate automatically into JavaScript Boolean types.

[Skip this: My application has a MySQL table of product categories that tell me whether I need to present the administrator with a long form or a short form in the HTML. So, as products are added over time, I want to the administrator to choose whether a new product category can take the short form plus some default values or will require the explicit input of all product values in the long form. As the administrator assigns a category to a new product - and changes his mind half a dozen times - I don’t want to keep on going to the server to do the look-up but want to have the table in Javascript to keep the form presentation responsive. Also, the MySQL tables are on a third party’s server remote from the web server.]

JSON/Array Question

Mar 6, 2007

Let's say I have the following JSON string returned from a server-side
process:

{ values: [{"name": "value1", "value": "1"},{"name": "value2",
"value": "0"},{"name": "operand", "value": "/"},{"name": "result",
"value": "NaN"},{"name": "error", "value": "Divide by 0"}] }

I then create a JSON object from it using eval() (tell me if this is
not what should be done).

My question is this...how do I determine (without going through every
single record) if there is a name=error in the values array?

Here's what I do now, it can't be optimum:

var object = eval('{ values: [{"name": "value1", "value": "1"},
{"name": "value2", "value": "0"},{"name": "operand", "value": "/"},
{"name": "result", "value": "NaN"},{"name": "error", "value": "Divide
by 0"}] }');

for (var i = 0; i < object.values.length; i++) {
if (object.values[i].name == 'error') {
//do stuff...
}
}

I thought I'd try object.values.name['error'] of course that didn't
work...

Jquery :: GetJSON() Assigning JSON Returned To An Array/var Outside Callback Function?

Oct 12, 2010

I'm trying to assign the values from the JSON data returned when I run this code into an array that's outside the callback function. The data is multidimensional, and I have been able to use this data within the callback function. However I want to use it outside that function. i.e. the jsdata returned in the code below is to be used outside the function

Code:
$.getJSON('../fxns/status.php',function(jsdata){
//do some stuff with JSON data or pass to global variable[code]..........

Jquery :: JSON Submit - Decode Empty Array At Server Side

Feb 22, 2011

I am doing a password reset form using Jquery and PHP. If I try to submit an email id it should sent and email and report back the response text as success so that the user knows email has been sent. But I am stuck with JSON submit as I have an empty array to decode at the serverside. I am using minified version of json2.js from the official json.org website

Here is the code.
Code JavaScript:
var formdata = $("#log-box").serializeArray();
formdata = JSON.stringify(formdata);
var notifymsg;
alert(formdata);
$.ajax({
type: "POST",
url: "forgot-pass.php",
contentType: 'application/json',
data: formdata,
success: function(responsedata){
var some = responsedata.split("&");
$.each(some, function(index,value){
//alert("index="+index+"value="+value);
});
},
error: function(o, s, e){
alert("Form not posted
"+e);
}});
formdata alerted gives:
[{"name":"email","value":"ravi.k@gmail.com"},{"name":"acctype","value":"loginaccount"}]

PHP forgot-pass.php
Code PHP:
print_r($_POST);
Gives
Array(
)

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).

JQuery :: IE (any Version) Is Not Parsing Returned JSON Via GetJSON Or $.ajax Calls?

Jul 6, 2009

I am trying out $.ajax instead of getJSON for debugging purposes. Because getJSON did not report an error in IE (6,7 or 8) and I am
trying to figure out why a jQuery plug-in is not painting my returned images to the screen in IE but is in other browsers. So I tried this. Interestingly enough, it hits the error event in IE but not firefox, safari and the rest and I don't know why (this code works great and renders my data just fine in FireFox and the rest). I know my returned json is valid:

$.ajax({
type: "GET",
url: "http://localhost:59396/sss/sssHandler.ashx?
action=getproducts&ids=" + ids,

[code]....

I don't know what else to do to troubleshoot why IE is having so much trouble with the returned JSON or just executing the function(data)
using either getJSON OR this. I have set the headers not the cache also in the response. IE refuses to enter my function(data) on the response.

[
{
"ImageTag": "u003cdiv class="CarouselItem
"u003e<p><img src="http://www.xxx.com/image/

[code]....

Same result. Firefox and the rest had no issue. IE still exited the $.ajax and my error method kicked in. No rhyme or reason whatsoever and I tried the IE Dev tools... nothing. About the only thing I get is this: Line: 163 Error: System error: -1072896658.Line 163 which is simply the line: function() { alert("An error has occurred. try again."); This has got to be the most f*d up situation I've been in and I need to get this working! I just cannot understand why IE can't parse a getJSON or $.ajax response, that is impossible or else there would be a huge meltdown with jQuery.

Convert Php Array To Array And Populate Form Text Fields

Nov 3, 2010

I am working on a page where the user will select a location from a dynamically generated dropdown list. I was able to create the php multidimensional array (tested and working) from a MySql database using the users information at login, but I'm having problems converting it to a javascript multidimensional array. I need to be able to access variables that I can pass to a number of text fields within an html form.For instance, if a user belongs to a company with multiple addresses, I need to be able to let them select the address they need to prepopulate specific text fields.
