How to debug :hover pseudo class in Google Chrome Developer tool

Google Chrome developer tool is simply one of the best tools available for debugging of HTML5 applications.

It has one neat feature: possibility to inspect CSS of element and editing it on the fly.

That works fine for normal styles, but what about :hover state?

There is one “hidden” option which allows to switch element to :hover state.

Inspect element of HTML. You should see Styles on the right hand side. There are 3 icons. Click the middle one with arrow sign. It will pop up menu with checkboxes. You can select here CSS pseudo classes like :active, :focus, :hover or :visited.


To learn more about capabilities of Google Chrome developer tools I recommend to go through free course Discover Dev Tools from Codeschool.com.

Quick online QR code generator in JavaScript

Update: quick access to this application – qr.sinusgear.com

I found nice jQuery plugin for generating QR codes written by Jerome Etienne: jquery.qrcode.

It’s fairly easy to use. Just pass a text to function and QR code is ready:

jquery('#qrcode').qrcode("this plugin is great");

Here is small application that generates QR codes on the fly as you type.

You can also download QR code as image (use: Chrome, FF, Opera or Safari for download).

Unexpected token ILLEGAL in jQuery.i18n.properties

jQuery.i18n.properties is useful library based on jQuery. You can use it to load .properties files with localization to web application.

I made upgrade of jQuery in my application from version 1.6.2 and application failed with error:

Uncaught SyntaxError: Unexpected token ILLEGAL

I spent some time debugging jQuery and i18n and I found out that one of .properties file contains weird property with name:

1_guide=1 guide

Problem was in numeric prefix. Solution is quite easy: fix property.

one_guide=1 guide

This problem occurs when you upgrade jQuery to 1.6.3 and higher.
