Cross Browser Event Handling in JavaScript

On May 22, 2013, in Javascript, by Anuj Gakhar

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 […]

Using HTML5’s ClassList API

On May 21, 2013, in Javascript, Browsers, by Anuj Gakhar

ClassList is a native and convenient alternative to accessing an element’s list of classes as a space-delimited string via element.className.

On February 25, 2013, in Railo, by Anuj Gakhar

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.

Mobile Safari CSS :hover selector and Back button

On February 14, 2013, in iOS, Javascript, Browsers, by Anuj Gakhar

Mobile Safari (iOS) has no concept of hover, in general. Obviously, with touch devices, you can’t have this feature. The screen needs to be touched for it to detect any user interaction. That makes sense. And with that in mind, it would be OK to say that we can ignore all :hover CSS rules, because […]

On December 27, 2012, in Javascript, by Anuj Gakhar

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 […]

On November 13, 2012, in Javascript, by Anuj Gakhar

I have been working on getting google analytics data using the Google Core Reporting API using OAuth2. 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.
