How to Debug Javascripts - Part2 (Firefox)

This is the part of the my How to debug Javascripts artical. This one will explain how to debug on Firefox using Firebug. See my previous artical on how to debug in Internet Explorer.

Firebug is not only a javascript debugger, it is a complete web debugging tool where you can explore the html DOM and much much more. And it is very easy to use. Once you install Firebug you will get a menu item in under the Tools menu. Using that you can enable and disable firebug for selected sites.



Once you open the Firebug you can inspect the javascripts under the Script tab and do the debugging. You can put breakpoints just by clicking the near the line number.



One special thing with Firebug is that you can put conditional break points. To add conditional break points just right click near the line number you want to put the break point and type your condition.



When there are Javascript errors in the page it is shown in the Firefox status bar. Once you click on that it will open all the errors in the console with possible reasons for that error. This will be very useful for you to find bugs in your application.



You can get more information on Firebug for Firebug site.

Navantis Avurudu Festival

It's Sinhala and Tamil New Year time.....
Navantis had organized a wonderful New Year festival last Sunday (8th April) at Brows Beach Hotel Negambo. It was wonderful event. Almost all of the employees and their family members participated for this event.
Festival started with a traditional breakfast which included Kevum(Oil Cakes) and Kiribath(Milk Rice). We had lots of game on that day. I participated for Goni Race(Sack Race) and Kaba Adeema(Tag-o-War). It was very enjoyable day.
