Set a word or phrase in an input field, clear it onfocus

This is a simple script to provide basic cross-platform XML request functionality in Javascript. It's meant to be the core component in any AJAX style framework. It is not an instantiable object, but instead is a namespaced microlibrary.

Calling is easy:
XMLRequest.GET(uri, query, callback, fallback)
uri: The location you're after
query: an associative array of form data to provide via the URL
callback: callback function of the form myCallbackFunction(objXMLHttpRequest), which is called upon successful (response = 200 OK) retrieval of the XML data
fallback: myFallbackFunction(objXMLHttpRequest), which is called upon failed (response != 200 OK) retrieval of the XML data.

XMLRequest.POST(uri, query, form, callback, fallback)
Similar, but does the query using the POST method. 'query' is the URL-appended data, still in associative array form, and 'form' is the same for the POST data.

Get computed Height of an HTML Element

A simple AJAX class. The code for the class is provided as well as example HTML and PHP code for usage.

This is a brief revision to my previous snippet. It is still what it was: a small, simple system for using XMLHttpRequest without using globals.

I'll put the API spec in the code this time, so as not to clutter the front page further.

Changes:

Changed name to HTTPRequest (far more accurate)
Added HEAD requests
Shortened code by making a GenericRequest function
Used a better method for getting an XMLHttpRequest object (checks multiple MS versions and implements the latest one)

Add dragging to your div elements. just adding class="drag" to the div element will make it draggable.

Here i'm adding an example for a draggable dialog box

To debug javascript code we use alert() whereever needed and it irritates you while alerts values inside a loop and other places where more alerts are being shown and you have to press the ok button to pass / proceed on.
here is a simple way to get rid of the alerts dialogs and get the values outputed into another debug window.

Get computed Width of an HTML Element

This is a PHP and JavaScript Image gallery that I created. There are 2 uses for this.
1.) You can save it as index.php and place in a folder containing images and it will display the images in that folder.
Example:
place index.php in images/folder
http://yoursite.com/images/folder/
This will display all images in that folder

2.) Pass in the path to the folder to display in the url
Example:
Save as imagegallery.php
http://yoursite.com/imagegallery.php?path=images/folde
