1. Monads aren't esoteric, abstruse computer science - they're useful.
2. You probably have used monads but just haven't realized it.
3. jQuery is awesome.

gRaphaël's goal is to help you create stunning charts on your website. It is based on Raphaël graphics library.

Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web. If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library.

HtmlUnit is a "GUI-Less browser for Java programs". It models HTML documents and provides an API that allows you to invoke pages, fill out forms, click links, etc... just like you do in your "normal" browser.

It has fairly good JavaScript support (which is constantly improving) and is able to work even with quite complex AJAX libraries, simulating either Firefox or Internet Explorer depending on the configuration you want to use.

It is typically used for testing purposes or to retrieve information from web sites.

HtmlUnit is not a generic unit testing framework. It is specifically a way to simulate a browser for testing purposes and is intended to be used within another testing framework such as JUnit or TestNG. Refer to the document "Getting Started with HtmlUnit" for an introduction.

HtmlUnit is used as the underlying "browser" by different Open Source tools like Canoo WebTest, JWebUnit, WebDriver, JSFUnit, Celerity, ...

HtmlUnit was originally written by Mike Bowler of Gargoyle Software and is released under the Apache 2 license. Since then, it has received many contributions from other developers, and would not be where it is today without their assistance.

Summary: The JavaScript Development Toolkit (JSDT) is an open source plug-in that brings robust JavaScript programming tools to the Eclipse platform. JSDT streamlines development, simplifies code, and increases productivity for pure JavaScript source files and JavaScript embedded in HTML.

JavaScript setTimeout Function - JavaScript Timing Events
November 16, 2007 by Blogging Developer

JavaScript features a couple of methods that lets you run a piece of JavaScript code (javascript function) at some point in the future. These methods are:

* setTimeout()
* setInterval()

In this tutorial, I'll explain how setTimetout() method works, and give a real world example. You may find the details of setInterval() method in JavaScript setInterval Function - JavaScript Timing Events
setTimeout()

window.setTimeout() method allows you to specify a piece of JavaScript code (expression) will be run after specified number of miliseconds from when the setTimeout() method is called.
Syntax

var t = setTimeout ( expression, timeout );

The setTimeout() method returns a numeric timeout ID which can be used to refer the timeout to use with clearTimeout method. The first parameter (expression) of setTimeout() is a string containing a javascript statement. The statement could be a call to a JavaScript function like "delayedAlert();" or a statement like "alert('This alert is delayed.');". The second parameter (timeout), indicates the number of miliseconds to pass before executing the expression.
Example



<script type="text/javascript">
function delayedAlert()
{
var t=setTimeout("alert('You pressed the button 5 seconds ago!')",5000)
}
</script>


<form>

</form>



An alert box will be shown 5 seconds later when you clicked the button.
clearTimeout()

Sometimes it's useful to be able to cancel a timer before it goes off. The clearTimeout() method lets us do exactly that. Its syntax is:

clearTimeout ( timeoutId );

where timeoutId is the ID of the timeout as returned from the setTimeout() method call.

$.extend({
myFunc : function(someArg, callbackFnk){
// do something here
var data = 'test';

// now call a callback function
if(typeof callbackFnk == 'function'){
callbackFnk.call(this, data);
}
}
});

$.myFunc(someArg, function(arg){
// now my function is not hardcoded
// in the plugin itself
// and arg = 'test'
});

This article discusses the advantages of the pseudoclassical pattern over the functional pattern. I argue that the pattern used by the Closure Library paired with the Closure Compiler removes existing hazards while I also examine the hazards introduced by the functional pattern (as defined in The Good Parts). First let me demonstrate what I mean by the functional pattern.

How to use JQuery (or other libraries) in a bookmarklet! With an example of making textarea's resizeable.
Chris Adams provides a template for creating your own bookmarklet and explains some of the reasons you might want to use this technique for development and testing. He also points out some gotcha's to be careful of.
