jquery - {body id="example" class="example2"} -

i have question. can use id , class in body? use them 1 control in jquery next removeclass , addclass.

 $('#example2').hover(  function() {   $(this).removeclass('example2');    $(this).addclass('example3');  },  function () {    $(this).removeclass('example3');    $(this).addclass('example2');  }    );  

thank every answer!

sure can use id on body or virtually tag including script tags, style tags, meta tags...

can simplify hover bit using toggleclass()

$('#example2').hover(function() {   $(this).toggleclass('example2 example3'); }); 

note need 1 of these on element start.

hover() 1 function argument work in both directions ... in , out. toggleclass() add or removing depending on current state
