Would like to know the concept behind the working of the URL below:

www.tradeshows.tradeindia.com/musician-expo2013/register.html

If any user clicks on the submit button without filling any information then a javascript pop up appears and all the important fields that has to displayed is shown one by one, I am aware about alert function of javascript but not aware to shown multiple alert messages on single alert if a single or multiple text box is empty.How to achieve this, Please guide?
