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.
I have the following code:
A = {
"value": "a",
};
B = A ;
B.value = "b";
alert (A.value); // => b
I expected A.value to be "a". how can I change values of a new object, without changing the parent-object?
I'm trying to get a return of
[
["red","green","blue"]
,["blue","red","green"]

I am having a terrible time getting the following code to work:
var foo = {
bar : "bar",
fooTwo : {
bar : foo.bar
}}
When this code runs, I am told that foo.bar does not exist in line 4. Why am
I getting this error?
Is it possible to have something like the following so that 'three'
can access 'one':
var x = {
one: 1,
two: { three:this.one } // Or parent.one ?
}
If not (which I have nearly come to a conclusion on) what is the next
best way to accomplish this?
i want the following var i="name";console.log({i:'value'}); o be equivalent to (as an end result)
var i='name'; var t={}; t[i]='value';console.log(t); is that possible?or must i use the second method?
I'm declaring a class in OLN:
Code:
The problem is that in IE, when I call myfunc() it complains with the error: Class is undefined
I'm not sure what I'm doing wrong. Class is declared in as much global scope as possible, and that shouldn't even matter in JS.
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?
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',

I'm building all my forms dinamically, calling a web service that returns me the field type, description and a set of rules for validation, all in JSON format. No matter how hard I tried, calling rules("add", ...) after adding the control to DOM does not work since I don't get the right format for the rules. Has anyone tried doing that (returning the rules with JSON and adding to a dynamic control)?
The rules come this way:
data.d[0].ItemRules
minlength:2
required:true
I am making a small gallery script. When a user clicks an image, I would like for a function to be called that tells the browser where that image is located in an object. For example:
[Code]...
It works, I just don't like it because it is messy and it seems sensible that some workaround exists.
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...
I have such problem when I post my object from client to server (php).
The object should be like so:
Code:
I converti it:
Code:
And send it though jquery and ajax:
property val is the object...
Then on side of server I gota string $_POST["val"]:
Code:
I try to convert it:

I'm trying to update a plugin i downloaded. What i'm trying to do, is make it able to work with dinamically created objects. I'm using the live function to assing javascript events, but i need to know how to assing a plugin dynamically. This is what i have right now:
$("#txtinstruments").AutoComplete("query"); What this does is apply the AutoComplete plugin, to all the objects with id txtInstruments that are already created but, i create more objects with that id on the fly, and i need to assign the plugin to them.
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.
My javascript, where I create the JSON object and try to send it through to the php page:
var JSONobj;
var JSONstr;
function createJSON(){
[code]....
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}
