I can not for the life of me get an ajax example/tutorial to work. I have tried dozens including prototype library and JQuery.
Here is my latest attempt:
As you can see I am trying to alert the variable teamH but I keep getting an undefined in the alert. I also tried a static drop down and I received the same undefined alert.
How I get that variable to contain my drop down choice?
In my UI framework, I have an event handler - just like many frameworks do. My handler is a static object, and contains methods to take care of things like mouse events, etc. However, upon adding a method to handle onfocus today, I ran into a very odd problem in Firefox. I've put together an example page that generates the error:

- Pages are loaded dynamically in a div,
- pages are php files
- pages contains scripts tags (static and generated via php) depending on
context
Load Scenario :
1. master page load pages via $.load jquery function
2. page are inserted and the script is executed (mostly input events or live events)
when i select another page (just imagine a combo with all pages listed), the Load Scenario is executed again... the 2 js code line that matter in the master page

This could appear under Ajax, for example, you could have multiple objects that make a singular ajax call (say an RPC-like request) and you need to update the object that made the call during the callback with the result, but it doesn't have to be. The particular problem I'm thinking about happens to be ajax, particularly with multiple objects accessing the same ajax request (meaning I can't use a global or temporary variable).
One way that seems like it would work (just thinking about it in my head), is to create a hash, and to pass the key through the request, store the key in the response, and pick it up on the callback side. Then remove the item from the hash when done.
I'm totally new to javascript world and i'd like to learn by writing simple examples and running them, my problem is i dont know how to do that, how can i compile/interpret .js files and see the results and the errors.
View 2 Replies View RelatedI would like to use a compiler to minifier my JS code. The JS code is separated over multiple files. For example, I have a language file (lang object), init.js files, common function files, ... here and there I even use global variables. I would like to use a compiler which also renames variable names to reduce JS file size. However, when the variables are separated over multiple JS files, and you compile each JS file one by one, the same short variable names will be attached given errors in the whole application.

That was a (beautiful) mind game :-) rather than
a practical thing to use.

as something not implemeted in language but
emulated by means of the language itself is: a
productivity impact is imminent, the question
is to minimize it).

I am having a problem getting the error container to clear out after I have fixed invalid inputs. I am using the invalidHandler option. When my form is invalid it shows a message of the number of errors (taken from the sample code) and shows the invalid messages. After I correct each error the corresponding message goes away but I am still left with the message of the number of errors.
Here is my setup.
$("#aspnetForm").validate({
focusCleanup: true,
onfocusout: false,
onkeyup: false,
submitHandler: function(form) {
saveAnnouncement();
return false;
},
invalidHandler: function(form, validator) {
var errors = validator.numberOfInvalids();
if (errors) {
var message = errors == 1
? 'You missed 1 field. It has been highlighted.'
: 'You missed ' + errors + ' fields. They have been highlighted.';
$("div.error span").html(message); .....
This may be a NOOB question and I am new to jquery itself so my syntax may just be incorrect but I do work with javascript and php quite a bit.Anyway here is a piece of sample code that is correct and does what is expected
[Code]...
From what I have read I believe the format is correct in my function. In PHP I have a print_r function that would dump an array where regular echo commands would simply output array so this may be a similar issue. I am not sure.
I am attempting to use the errorContainer, errorLabelContainer model to display all validation errors. I have a field that is not required, but if there is data in it, it must be a number between 100 and 65535. If I enter an invalid number and change focus, the errorContainer appears along with the error message. If I empty the field, the error message goes away, however the errorContainer is still visible with the it's global error message. Is there a way to get the container to hide also?

Is is possible to compile a link from form input values? Basically I need to compile a url string to fake a CMS search. It's a crude solution but I have no other options at this point.
So, the user fills this in an clicks submit which takes them to whatever url it has complied.
The url is quite complex but consistent, the resulting values will be at certain points in the url
So... http://somesite.com/search.php?categoryid=435834y59?keyword=KEYWORD VALUE?catalogue_number="CATALOGUE NUMBER VALUE"?price_from=PRICE FROM VALUE?
etc
<label for="keyword">Keyword</label>

<label for="catalogue_number">Catalogue number</label>
<input type="text" name="catalogue_number" value="" id="catalogue_number">

I have my site set up so that everything is done with AJAX requests to a script depending on what action is taken. If my script returns an error - such as the user is not allowed to take the action they tried to take - it returns an error message.
What I would like is for AJAX to know when there is an error returned, and I know there is an error parameter for the ajax function, but as far as I know that is only for HTTP error codes - so how would I modify my PHP script to return an error that the ajax would know it is an error?
Let's say you have a little Ajax script and it sends data to the server to do something. Now the server has an issue of some kind (let's say with the query) and can't so what you expect it to do. What's the best way to tell your awaiting Ajax functionality something went wrong?

I want to have a textarea update a database column and then pull down the info from that column and display it, without refreshing. I'm using JQuery and AJAX and PHP and SQL to do this. So far I've been able to update the database row using my $.post() call. The strange thing is, my variables don't seem to be passing to the page - when I try to echo them or look at them they don't show up. Here is my simple index page and call (page names aren't indicative of what I'm trying to do, just placeholders):
<head>
<script src = "https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.js" type="text/javascript"></script>

$(document).ready(function() {
$("#updatefield").click(function(){

I'm not sure why my ajax is throwing a cross site scripting error. I have a php page that request a page not in my domain. I have another page where my ajax requests the php page, which is in my domain. Then the error is thrown. Since the php page is in my domain, why would the error be thrown?
