If you are using jQuery, you can easily use .bind() and .unbind(), or .on() and .off() to attach/detach event handlers on DOM elements. But there are times when jQuery is not available/desirable in the project for various reasons. This is actually quite easy to do in native JavaScript, without any libraries. Most browsers register the […]
ClassList is a native and convenient alternative to accessing an element’s list of classes as a space-delimited string via element.className. It makes it easier to accomplish common tasks such as adding class, removing class etc. I find myself using the ClassList API more and more recently (as opposed to the equivalent jQuery functions) and I […]
In this post, I will be demonstrating how to write a simple Grunt Task that would concatenate and minify your Javascript and CSS source files. GruntJS is a Javascript Task Runner that automates certain tasks and saves a lot of time. There are hundreds of plugins available and the community is growing quite impressively. The […]
I recently installed Railo 4.0 on a standard Amazon Linux AMI using the Railo 4.0 64-bit installer and everything went fine except that on startup, Railo won’t automatically startup.

In my latest project, I’ve been working on a HTML5 Mobile App for iPad and one of the things we wanted to get rid of was the 300ms click delay that Mobile Safari has. There is a reason for the delay to be there in first place, i.e. the browser is waiting to see whether […]

This is a very common Javascript question that confuses a lot of people (including me). You can use both function.call() and function.apply() in Javascript to execute a function but what’s the difference? Let’s look at the documentation of call() and apply() first. According to the documentation, .call() means :- Calls a function with a given […]

After the initial oauth dance is done, I store the access token and refresh token in the database to be able to regenerate valid access token from the refresh token. This is termed as offline access.
