JQuery :: Get Function Returning String Not JSON Object

Aug 5, 2009

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?

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?

Put A Function In A Object Created Using JSON Notation

Aug 23, 2011

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.

If Statement To Check Whether String Is A String Is Returning False

Jan 25, 2011

I have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function.callback should be a string so why is it saying otherwise?

Pass Object In Function Instead Of String?

Apr 28, 2011

In the following example, I use the function "SetUp(SBox,AObjStr)" to send an object reference to the function "Populate(SBox,SObj)".

Seems to work OK, but it is a 2 step process to assign the JSON objects to the selected drop-down boxes. Fairly easy, but somewhat tedious, to change to fewer or more levels as desired with a common bit of code.

However, what I would like to do is simplify it a bit more ... Is there a way to bypass the "SetUp" function to "Populate" the multi-level drop downs directly? I think what I'm looking for is a way to pass a string in the function that would be recognized as an object (in this case a JSON or other form of array) and be decoded to add options to the drop-down choices, but I don't have a clue as to how that might be accomplished without the extra "SetUp" function!

Code:
<html>
<head>
<title> Passing Object Indirectly </title>
<script type="text/javascript">

JQuery :: Functions Are Returning A Deferred/promise Object?

Nov 7, 2011

I've been going through the documentation for the deferred objects API, and one thing that's still not clear to me is : what jQuery functions are returning a deferred object?

The documentation seems to say that jQuery.ajax() and the animation functions like jQuery.fadeIn() does (what about jQuery UI effects?), but the pages for those functions say they return a jqXHR object and a plain jQuery object.

JQuery :: Treat A String As JSON?

Sep 7, 2009

I use $.getJSON for all my ajax stuff and it works beautifully but there is one particular situation where I use an iframe hack to do an ajax file upload and even though the returned value is a json object (created with PHP), jQuery treats it like a string. I'm using json2.js right now and it does the trick but I don't like including that much extra code because of one rare situation. So my question is, be it with $.getJSON or by specifying 'json' as the expected return type of an ajax request, jQuery *seems* to be able to convert into json. The string returned is already a json object, I just need jQuery to be able to treat it like one. I've tried wrapping it in a jQuery object but no use. (and I really don't want to go down the eval() path)...

JQuery :: Parse A Json String Received By $.getJSON()

I'm trying to parse a Json string received by $.getJSON(). I can receive the string but firebug gives me an "invalid label" error. I think it is because the string is an hash array with a number as first label, but I'm not sure. This is the string:

{"15":{"id":15,"x":0.4589937586135409,"y":

JS Not Returning CSS Object Attribute Values

Mar 23, 2009

From the code given below, I think it's pretty obvious what problem I'm having, but I'll explain:

Javascript is only returning HTML DOM attribute values when they are assigned by the javascript function, not when they are assigned by CSS. So, if I set the background colour of a div using CSS, then try to call that attribute value, JS doesn't return it, BUT, if I then assign a new value using JS, it can correctly read the attribute value.

What am I doing wrong? Or can javascript not pull HTML DOM attribute values assigned by CSS?[code]...
