javascript - Targeting $(this) within nested for each loops in jQuery -

i'm trying figure out, when iterating through list items, how target each "$(this)" equivalent within nested foreach loops. here example of problem:

$('li').each(function(){         // believe $(this) target each li item...     $(this).children("li").each(function(){         // ... how can target each of these li items? doesn't $(this) target original loop?     }); }); 

$('li').each(function(){     var $this = $(this);     $this.children("li").each(function(){         $this; // parent li         this; // child li     }); });
