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',
[Code].....
I'm making a call to a Twitter JSON feed, and when I pass an incorrect username, jQuery's ajax complete method never gets called.
An example of a JSON response that causes complete not to be called (nor error, nor success) is: [url]
Here's my code:
Any ideas on why the complete method isn't getting called? Shouldn't this always get called?
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){
$.each(data, function(i, value) {
alert(value);
}, "json"
);
});
When I run it I get each character printed out one at a time in a separate alert. And then when I used this line of code:
alert(typeof data);
It tells me that 'data' is a string. Shouldn't it be a JSON object?
Im having difficulty getting my form contents to send to my php page using ajax, jquery and json. The results just doesnt want to show.
My javascript, where I create the JSON object and try to send it through to the php page:
var JSONobj;
var JSONstr;
function createJSON(){
[code]....
What should happen is the firstname should be alerted. But the alert box doesnt even show and I find no errors using firebug...
I am trying to populate page elements from an AJAX call, which returns JSON.
For some reason, JSON that looks like this, fails to evaluate, I'd like to understand what's wrong with it.
JSON:
Code:
Im currently creating a textbox with an AJAX auto-complete feature but have reached a wall. I can create a div below it with a list of results but now need to allow the user to select. I can setup it up with an onClick, easy. But I need help with the arrow buttons as that is how I would like it to function. The script only allows 5 results at a time with each having an id of 0 to 4. Each result is a div, below is this code (created by PHP):
PHP Code:
echo "<div id='".$i."' class='userSelect'>".$i.$row["friendName"]."<div>";
There is a JS file attached to the page this is echoed onto, so what would the code need to be on both the div (mouseup, mousedown...) and then the function that calls.
I'm trying to fetch JSON contents via ajax() from a file using this code:
// grab pages via AJAX request
sm.pages = (function() {
var json = null;
$.ajax({
async: false,
global: false,
url: 'pages.json',
dataType: 'json',
success: function(data){
json = data;
console.log(data);
}});
return json;
})();
One problem though. The success function doesn't seem to be firing at all even though I can see the request was successfully in Firebug.
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've been using $.get() and $.post() extensively, but then noticed the more functional $.ajax, which lets you handle server-side errors using the "error" option. The parameters to the callback function for the error option are:
(xhr, status, exception), where in the documentation it says "exception" is the Exception object if it's supplied.
My server-side is PHP, and when I perform a:
throw new Exception("You can't do that!")
or
trigger_error("You can't do that!", E_USER_ERROR)
It does run my error callback, but it puts 'undefined' in the "exception" object, and my custom error message is nowhere to be found. How do I populate that Exception object on the server side, so that the error callback can then access it?
I'm not sure if this is a php issue or jquery issue. When I complete the form and hit submit it puts the successful message up like its supposed to but also with the fields still filled in the form which it shouldn't be doing and it doesn't actually post in the database so I'm not sure if its a php issue or jquery issue.

I have what I think is a simple $.ajax() call.I added complete and error functions but a time out in firefox 3.5.2 doesn't cause the error function to be called and when the complete function is called both parameters are undefined.If I make the ajax call return a http 500 response the error function is called.[code]Running on FF 3.5.2, JQuery 1.6.2 on XP Pro.

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'm trying to create a two-part animation: On mouseenter over a thumbnail image, the background area expands. Then, once the background has reached full size, I add a class to the text content so that it gets displayed.My problem is that the text content only displays sometimes and I can't determine why this is the case other than that it has something to do with the callback. If you roll over the thumbnails, sometimes you see some text information below the image and sometimes you don't. Why? You should always see that text information.

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 RelatedDo 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 8 Replies View RelatedI have a slogan that is supposed be animated so that one part slides onto the screen, followed by the other part. My understanding of the 'callback function' parameter on the .animate() function is that it's not supposed to execute until the animation is finished. The trouble is, the two functions seem to be executing at the same time (that is, the two parts of the slogan appear on the screen at the same time.) Here is my code:
$(document).ready(function() {
// hide slogan text $('#slogan_1').css('left','270px');
$('#slogan_2').css('top','75px');});

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 have created a JSON object through a PHP script. The code is as follows:

I would like to redirect my request from a page to another one with a json object. The only way i have found to do this is :

Is there a way to do this without using .Ajax ? With this method i have to save my json object in my session to reuse it after and i don't like that !
