check for className before running the function

How can I achieve this?

for each pages I have attached a unique class-name so I can target them by css later.

I want to run a function but only targeting the homepage.

eg.

if($('body').hasClass('pageHome')) {
 callMe;
}

function callMe() {
 alert('I am Home!');
}

Concept should work fine as long as you are wrapping code in 

$(function(){  /* run code*/ })

and you need to add "()" to callme();

It looks like you're close. To call callMe, you'll want parenthesis to indicate that it's a function call:

if($('body').hasClass('pageHome')) {
 callMe();
}

Your forgot the parenthesis when you called callMe:

function callMe() {
    alert('I am Home!');
}
if($('body').hasClass('pageHome')) {
    callMe();
}

Does that help?
