jquery - Counting classes up with each -

-

i trying give each .scan new class increasing count

what have tried using each function jquery , using $(this) $(this) allways contain class name every .scan changed.

$( ".scan" ).each(function() {     = 0;     $(this).addclass( "count"+i );     i++; });

the result 

<div class="scan count0"></div> <div class="scan count0"></div>

but want 

<div class="scan count0"></div> <div class="scan count1"></div>

here fiddle current state.

every tipp/help appreciated.

i.e. because defined inside each method.you need set value outside each method:

var = 0; $( ".scan" ).each(function() {    $(this).addclass( "count"+i );   i++; });

however can use default argument parameter index of each function give incremenetal class suffix:

$(".scan").each(function(i){   $(this).addclass("count" + i); });

working demo .each

or use callback function of addclass() method:

$(".scan").addclass(function(i){   return "count" + i; });

working demo .addclass
