If you wanna check for a string within a p's class, you may use a simple search. Say you have your 'p' inside a div.

$('#your_div p').first().attr('class').search("_header")

This returns -1 if false or no match found, & index if true or match found.

OR you can directly access your 'p' using other answers submitted here.
