We have a corporate product which uses ajax and different layers of soa , java etc across all browsers and multiple platforms But the observation is - IE8 is extremely slow when working with ajax framework. THe browser processing time increases exponentially with increasing js file size. Works fine in non IE browsers.

Working on creating my own plugin and realized that I would very likely end up doing this again in the future. Unfortunately, I have an extremely short memory when writing code. I frequently have to re-read the code I've created the day prior so I can get back on track with what I was doing. As such, I'm a fervent commenter in my code.
So, I'm creating a jQuery plugin framework with comments for everything that's going on in the framework to prevent my brain from having to re-learn everything in a month or so when I do another one.
Plugin-savvy folks to take a look at this code and help me fill in the blanks and make corrections to those places where I'm way off base. As you'll likely notice rather quickly, this is taken from the jQuery plugin tooltip construct found here: [url]
I'm having trouble using jQuery to find get select box values by element name. At the moment the code is in a for loop and it gets 8 different form values and puts it into an array. Currently this takes 1.5 seconds to execute which is far too slow as the user has to wait for it to finish. Here's the code which is inside the loop:
[Code]...
This when run executes instantly with no time delay. Why is the jQuery way so much slower? I'm all for saving 2 lines of code but not when it's 10x slower. Also I shouldn't need to put an id on the select box element to make finding it faster, the name value is already unique because I require the specific value once the form has been submitted.
what is the best js framework for ajax ? first iam a beginner in ajax and js,
i found a lot of frameworks but i didn't know which is the best.
And i heared that some of thease frameworks are not updated any more. I read a book called professional ajax with php and the book author was using a class library called zXml you can find it here but i found that the XMLDOM does not support opera browser it supports only IE and FireFox .
And I heared a lot about prototype class library but i didn't found tutorials using it you can found it here so iam unable to deciding which is the best updated cross browsers js framework for ajax.
Which is the best JS/Ajax framework according to you ?
JQuery
Prototype
Mootool
Script.aculo
(Did I miss anything ?)
I have a problem with the jQuery.ajax() function combined with a keyup event (i think key events in general). I'm binding an keyup event to an input field so that on every change the current input is send via the ajax function and receives new data from the server, displaying it in a selectbox.
when I'm typing very fast it seems that the ajax function is too slow for this and shows up old result elements. After triggering the event another time, e.g. via UP,DOWN,.. it receives and displays the correct data.
i have a div which i am showing and hiding based on a button click.now when i click button first time, div will show with slow effect. but when i click button second time, the div hides quickly...
if( visible==0 ) // parent div not visible, show the div
{
visible=1;

I am developing quite a complex user interface in jQuery that relies on an AJAX call to retrieve JSON.We have noticed that the code runs slow in IE7. IE8 and IE6 are acceptable. Firefox and Chrome really quick. I have traced the problem back to the AJAX call, which IE7 seems slow o process. What takes less than a second in the other browsers will take IE7 3 or 4. I have googled for an answer it seems there is some consensus that the native XHR in IE7 is slow, so it may not be a specific jQuery problem.Has anyone else experienced this? Does anyone have a solution? Please consider that this will be a public website, so the solution cannot involve altering settings on users' machines.

View 2 Replies View RelatedThe standard Number.toString() method returns values in scientific notation once they exceed 10^20. In many cases, this is not an expected or desired result.
The toLongString() method provides a solution by always returning a literal numeric value regardless of the number's size. However, the value returned will not be accurate beyond the first [log base (radix) of (10^15)] digits.
radix: Optional. A number between 2 and 36, inclusive.Number.prototype.toLongString = function(){
var radix, n = this, d, t = '', p = ''
if(arguments.length>0 && typeof(arguments[0])=='number'){
radix = Math.round(arguments[0]);
if(radix<2) radix = 2;
if(radix>36) radix = 36;
} else {
radix = 10;

while(n > radix){

This code works to insert a MySQL record to a Database using AJAX. It works fine on IE, but it's not working on FF or Chrome. When I test it on FF/Chrome, i just get the text "Just a second..." and it doesn't advance from there.
Iam planning to build a good 2.0 web application with minimal modules but each module should be feature rich.
so i would like to use AJAX to spice up my site.
(i will be using php and mysql for it)
so please suggest me, should i hand code everything or should i use an AJAX framework?
if so which is good ajax framework and why?
I get that this question is going to be one of those questions where everybody defends the app they like the most, but I am asking for the reasons why rather than just a one product name answer, so here goes with the question:
What is the best Javascript Framework to use for Javascript RIA development and why?
i.e. Qooxdoo, ExtJS, Echo3, etc?
Now I know everyone is probably going to jump in and say Jquery, but personally I see Jquery and the likes as more of a "make plain website nice by adding animations etc" rather than for web applications development.
One of the great annoyances I have with JavaScript is the lack of a good
consistent code library. Oh, there are a few code libraries scattered
around for doing various things. The problem is that each of them have
their own way of doing things. If we want to use more than one library
at a time, we often end up duplicating code and working with different
interfaces and practices that aren't necessarily compatible with each
other...
So... isn't it about time that we have a Common JavaScript Framework?
I'm thinking of a standardised code library, mostly (but not entirely)
built from the free code that is already out there. (I'm thinking of a
LGPL core with independantly licensed extensions.)
I know of a few very cool projects that aim to make JavaScript
development easier, more professional and to bridge the gap between
browsers and environments. (To name a few: DynAPI, DOMAPI, Sarissa,
13th parallels' library, netWindows, bindows, ActiveUI, f(m).) But I
don't know of any effort to bring all of these features into one common
framework. Can we do anything about this?
I'm not exactly proposing that we form a group to design and implement a
complete framework. I just think that, us, JavaScript developers should
talk to each other more and agree on a few things. Then, I imagine
being able to access this centralized, well designed library that is
ready for serious (and less serious) development and the dream goes on...
I have been working with JS (client and server) for some years now and
I'd like to bring more consistency to my code and spend less time
writing lower level code. So I may be writing this email more out of
wishful thinking than determined action. In any ways, I remain
interested to support any effort that would lead me to better, well
designed, programming.
I'm experienced with PHP and I'm familiar with JS syntax but still a beginner.
Now I want to learn AJAX And JS and I've looked at jQuery but it doesn't look like JS to me, I mean I'm sure it is but it looks to me like jQuery has a syntax of it's own and I want to learn not just a framework but also the underlying language.
So now my question is; what framework will be the best choice when that is my goal?
AjaxI need to know which is the most used framework and why.
I know that there are many websites on the web about it, but I can't use them only.
I never use jQuery, but i saw jQuery in zul pages from ZK framework. i'm ZK developer here.
So my question is just same with my subject,is that possible use jQuery in composer.java?
Where can i find the procedure for build my own website. It would be a great help if anyone give the information.

BUT, without needing a framework (jquery,mootools,scriptalicious,protoype,dojo,etc). I don't need all the extras that come with the framework and want to keep loading time down to a minimum.
Everywhere online seems to need a framework.
Modello is a lightweight framework that enables you to write JavaScript class like other class-based object-oriented programming language. It introduces class, class-based inheritance, multi-inheritance, private members, RTTI and more into JavaScript. Modello can help you write more readable, reusable and maintainable JavaScript code.

I have been tasked with building a slider for a client. Basically you have a window showing 2 thumbnails and some product info. When you click the arrows, it would slide to the next or previous set, WITH EASING. Normally this would be simple using jquery, but I cannot use a JS framework, so I have to use straight JS.
