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.
[Code]...
Maybe I'm missing something obvious here but I'd like to know if there is a "proper" way to attach a single callback to both a deferred Object's done() AND fail() methods?What I really would like to be able to do is support both a catch-all callbackAND promises on the same function.

Basically what I'm trying to do is write a plug in which connects to a sharepoint web service, traverse the results of the xml document that is returned by the web service for certain elements, and then return a collection of xml elements which I can use in another function on the page that is calling the plugin.My code looks like this:Main Page

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?
Need some help with my For loop. The issue is that, my loop is only returning the values of the last item in the js file. I want the select box to include all possible names.
Code:
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]...
How would I go about copying all the prototype functions AND the constructor from one object into another object, and then call them?
I know I can use this.example.call(this), but that's not an acceptable solution. I want to deploy this style over dozens, potentially hundreds of objects.
I'm just starting to try out "Ajax" web programming and I've got a question.
AJAX is fairly straightforward. Javascript creates an XMLHttp object and
then uses that to generate a hidden webpage with your results.
What I'd like to know is, how can I retrieve multiple values from an XMLHttp
request?For example, if my request generated an SQL query that returned a
Name, Address and PhoneNumber, could I get those values directly instead of
parsing them out of the ResponseText?
This is my current handler:
function showResult(pge) {
var url="getResult.asp?sid=" + Math.random() + "&q=" + pge
xmlHttp=GetXmlHttpObject(stateChanged)
xmlHttp.open("GET", url , true)
xmlHttp.send(null)
}
function stateChanged() {
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete") {
//Complete, so show results.
document.getElementById("myResult").innerHTML=xmlHttp.responseText;
//How to get mulitple values here?
}
}
I am trying to call a custom function after ajax request is complete.When I fire this, the someMoreCode is fired before the ajax request is complete. Can't I chain custom funciton with deferred?
View 3 Replies View RelatedTo enhance user experience on my site, I've moved a few page elements (well, the ads...) to the end of the page (in a hidden div) and when the page is loaded the content of such divs are copied to their appropriate location on the page. This makes the content load much faster and thus not delay the user.So what I did works perfectly with IE/Opera but th FireFox is causes the page to try and reload, which it never succeeds to and so we're stuck with a blank page. So yes, the problem is that there are document.write calls inside those divs which contain script but I cannot change it (google ads / ebay ads)I even tried to use setTimeout() to ensure the content is loaded (and can see that it is) but still when the move is done, the page tries to reload.
HTML side:

<div id="xxx_slot"></div>

var empty = {};
var defaults = { validate: false, limit: 5, name: "foo", buttons :

I am using objects in JS and I am trying to add draggable() into a DIV that works when I move the function out of the object context.
Example:
Code:
That does not work. However, if I do this:
Code:
Then it will work... because the draggable() function is not within the object.
I need this to work within the object, because I will have several DIVs associated with objects and I need them to have draggable() in specific cases.
I am trying to get the index of a li with a specific class. I know I'm selecting the right object because I can apply a CSS class to it (eg change border colour) but when I try to get the index it returns -1. But I know the object exists as I can alter it. :-s
jQuery(document).ready(function() {
var active = $("#tertiarynavigation .bordered").get(0);
var num = $("#tertiarynavigation li").index(active);
alert("Index: " + num);

View 4 Replies View RelatedMy application uses Web pages whose grid is defined by several tables. I noticed a funny behavior on IE and Firefox which is giving me pains.
Apparently, when the browser renders a <table> tag and before it reaches the </table> end tag, any document.write actions in Javascript get deferred execution till closure of table instead of occuring at runtime as they are parsed. Code:
Usually I have various JavaScript functions for common functionality on my pages (i.e. select all, export, etc.). Typically I will create a common.js file and place these functions within it. Is there any advantage to create a client side object which encapsulates this functionality such that I'd use something lik common.SelectAll() or something similar?
Not sure if there is a best practice peeps follow for this or not.
Currently, I'm building a website with jQuery. The function below helps me to get content from a database. In the file content_ajax.php there are some functions to handle ajax-requests. JS calls the PHP-function correctly (I've send an email to myself inside that function to check) but the script doesn't return 'succes' and doesn't give me an error...Also, when I put an alert inside the succes and error function, it doesn't popup!
What may be relevant: - site uses mod_rewrite for friendly url's
I have this basic code following and its not returning anything at all. Even the alert is not alerting. I have checked and the select is sending the value fine But nothing happens on return. What i am missing?
$(function() {
I have a bunch of divs with the same classname, 'mediafield':
And I have this jquery code in my header:
So I know that the click function is getting implemented.. The alert box appears however I get the following error in firebug: uncaught exception: Syntax error, unrecognized expression:[@class=mediafield] Line 0
Nothing happens when firebug is turned off... So I'm not sure why it's throwing the error.
I'm working on a small project and want to create a simple dialog window. I know I can use a plug-in, however that is a bit of a over kill plus its a good way to learn more about jquery.
So everything was going well until clicking the button. I cannot find a way to return the value of what button was pressed so I can take further action within the function.

I have CSS defined as:
#container {
width:400px;
border:1px solid red;
}
I was not able to get the value using $("#container").css("border"), but $("#container").css("width") is ok,
As an exercise, for the past few days I've been attempting to build a simple search and return data to a page.
The form parses vars to PHP with no refresh PHP gets stuff from the database PHP echos an array Array is output using Jquery in my #result div
Things seem to be working nicely, and the array is indeed coming out the other end.
My next aim was to be able to do something with the output. The first step I assumed would involve printing that array to a table. It's this that I'm having trouble with. I can't figure out the syntax.
With regards to the following code, I think the success function on line 32 and 33 should be something like:
$.each(something something) more something's with TD's and TR's interspersed
The code I have so far is as follows. This successfully echos out the contents of the array, but ultimately isn't useful without being able to access the elements.
<html>
<head>
</head>
<body>

How do i return many lines of data?
The page eventos_search.php is supose to get more then 1 line of records
This process i dont know how it works.
i happen to chase my fortunes in development as a newcomer. Scenario,// using jqm-rc2, sample registration - ajax callback scenario
1. Say formtoregister.phpcalls a studentsregister.php // Ajax/json and POST
2. Thisstudentsregister.phpdoes this 2.1 validates POST data, does db work and 2.2 sends back to formtoregister.php following messages //on success echo json_encode($promoinfo);// json format, see below the echoed content echo "<p>Welcome $user </p>" problem,is plain format text is printed Message is: {promo code: JsonNAjax}<p>Welcome Beginner </p>
