Few days ago I decided to look into an issue that was reported on our forum. Basically the form validation in CMC was not working on Safari. The whole thing was very strange because we are using the Joomla! js classes to validate the form before submitting, so there was no reason why all this would not work. As I looked into the code I discovered things that I never knew & thought that it is a good idea to share them with other developers.

Since the Joomla! 1.5 days developers were able to use JHtml::_('behavior.formvalidation'); if they want to validate their forms with javascript before submitting. On Joomla 3.3 the formvalidation function looks like this.
