Ok  so in a comment above the question asker Fidilip said that what he she s really after is to get the path to the current element   Here s a script that will  climb  the DOM ancestor tree and then build fairly specific selector including any id or class attributes on the item clicked   See it working on jsFiddle  http   jsfiddle net Jkj2n 209    lt  DOCTYPE html gt   lt html gt   lt head gt   lt script src  https   ajax googleapis com ajax libs jquery 1 11 0 jquery min js  gt  lt  script gt   lt script gt        function                    on  click   function e              e preventDefault              var selector     this               parents                map function     return this tagName                  get                reverse                concat  this nodeName                join   gt                var id     this  attr  id              if  id                 selector         id                         var classNames     this  attr  class              if  classNames                selector            trim classNames  replace   s gi                               alert selector                          lt  script gt   lt  head gt   lt body gt   lt h1 gt  lt span gt I love lt  span gt  jQuery lt  h1 gt   lt div gt     lt p gt It s the  lt strong gt BEST THING lt  strong gt  ever lt  p gt     lt button id  myButton  gt Button test lt  button gt   lt  div gt   lt ul gt     lt li gt Item one      lt ul gt         lt li id  sub2   gt Sub one lt  li gt         lt li id  sub2  class  subitem otherclass  gt Sub two lt  li gt       lt  ul gt     lt  li gt   lt  ul gt   lt  body gt   lt  html gt    For example  if you were to click the 2nd list nested list item in the HTML below  you would get the following result   HTML gt BODY gt UL gt LI gt UL gt LI sub2 subitem otherclass

WARNING     selector has been deprecated as of version 1 7  removed as of 1 9   The jQuery object has a selector property I saw when digging in its code yesterday  Don t know if it s defined in the docs are how reliable it is  for future proofing   But it works          selector    returns     Edit  If you were to find the selector inside the event  that information should ideally be part of the event itself and not the element because an element could have multiple click events assigned through various selectors  A solution would be to use a wrapper to around bind    click   etc  to add events instead of adding it directly   jQuery fn addEvent   function type  handler        this bind type    selector   this selector   handler        The selector is being passed as an object s property named selector  Access it as event data selector   Let s try it on some markup  http   jsfiddle net DFh7z      lt p class  info  gt some text and  lt a gt a link lt  a gt  lt  p gt       p a   addEvent  click   function event        alert event data selector      p a         Disclaimer  Remember that just as with live   events  the selector property may be invalid if DOM traversal methods are used    lt div gt  lt a gt a link lt  a gt  lt  div gt    The code below will NOT work  as live relies on the selector property which in this case is a parent   - an invalid selector      a   parent   live function     alert  something          Our addEvent method will fire  but you too will see the wrong selector - a parent

Just add a layer over the   function this way    x000D   x000D       function jQ     x000D   return  function      x000D    var fnc   jQ apply this arguments   x000D    fnc selector    arguments length gt 0  arguments 0  null  x000D    return fnc   x000D       x000D         x000D   x000D   x000D    Now you can do things like    a   selector and will return  a  even on newer jQuery versions
