Question

I know that i can simply write a plugin for it and i know that i can do this manually. I am just looking simple way if jQuery provide such as option.

Actualy each method will work as expected but it does not make feel it is effective way because it is clear that there is no iteration. There is only one element.
Check example below.

$('a').first().do(function(element){
  //do your job
}).end().eq(2).do(function(element){
  // do another job
});

Answer 1

jQuery each()

$('a').first().each(function(element){
  $(this).html("foo");
}).end().eq(2).each(function(element){
  $(this).html("bar");
});
