Waiting Until User Stops Typing to Check the Status Using Ajax

Tue, 13 Jan 2009 00:00:00 +0000

There are many cases when you have to check some status in the server side while the user is typing in the data. One example that comes to mind is the username check - you can check for the availability of the username when the user is keying in the name. Usually this is done on the 'onchange' event. It can be done on the 'keypress' event too - but not many people prefer that because its expensive. Fetching data from the server takes time. A better method is to wait until the user completes typing to check the data - I'll show you how to do that in this tutorial.

JSON Encoder/Decoder For JavaScript

Mon, 03 Nov 2008 00:00:00 +0000

JSON(JavaScript Object Notation) is a lightweight computer data interchange format. It is a text-based, semi-readable format for representing simple data structures and associative arrays. The main advantage of using JSON is that it can be parsed into an object using very little code - and for this reason, many people(including me) prefer using it as the ajax response format.

Fri, 29 Feb 2008 00:00:00 +0000

Ajaxian is a very important site for javascript programmers. Unfortunately, it is very slow in my system. The problem is caused by the small fixed background.

Handling Keyboard Shortcuts in JavaScript

Thu, 12 Jul 2007 00:00:00 +0000

Despite the many JavaScript libraries that are available today, I cannot find one that makes it easy to add keyboard shortcuts(or accelerators) to your javascript app. This is because keyboard shortcuts where only used in JavaScript games - no serious web application used keyboard shortcuts to navigate around its interface. But Google apps like Google Reader and Gmail changed that. So, I have created a function to make adding shortcuts to your application much easier.

Decrypting Anti-Spamming Email Encryption

Fri, 09 Feb 2007 00:00:00 +0000

We have all seen people encrypting their email address when printing it online. These is to prevent the spam bots from reading it. Ordinary emails like me@somewhere.com become me -|at|- somewhere -|.|- com. To test the effectiveness of such 'encryption', I have created a small regular expression based script. Just enter your encrypted email in the first box and see if my script can decrypt it.

Rounding Numbers to a given Decimal Point

Wed, 17 Jan 2007 00:00:00 +0000

For reasons that are beyond me, Javascript does not have a function that could be used to round a number to a given decimal points. If you want to show the price of an item in the format 5.00, you cannot just call a function round(5,2) to do it. Yes, Javascript has a rounding function - Math.round() - but that function just rounds the number to its nearest integer. So, as always, I have created a function that will do this...

Class Manipulation using JavaScript

Mon, 04 Sep 2006 00:00:00 +0000

As you may know, JavaScript is for behaviour and CSS is for presentation. But often we use the 'style' property of an element to change the apperance of an element. A better way of approching the problem is to change the classname of the element in question and define the class in the CSS file. These functions will help you do that.
