How to check (if statement) body element class value in Prototype JS library?

How to check body element (<body></body>) in prototype?

This is not working:

        if( $('body').hasClassName("catalog-product-view") ){
          alert("yes");
       }

        if(!$('body').hasClassName("catalog-product-view") ){
          alert("no");
       }

Thanks for any advice.

to catch the body element do :

$(document.body)

this will return the body element !

to check the class use :

$(document.body).hasClassName("catalog-product-view")

and finally you can do what you need with :

$(document.body).hasClassName("catalog-product-view") ? alert("yes") : alert("no");

That code is looking for an element with an id of 'body'. Try giving the <body> an id and referencing that.

Edit: or, looking at How to add an element to 'body' using Prototype?, use $$('body')[0]
