带有JS和Google Chrome的Xpath

Question

I have a code for generating xpath on click but i need to put that in an chrome extension. So how to do that?

Here is the code for generating xpath on click:

function get_XPath(elt)
         {var path = '';
          for (; elt && elt.nodeType==1; elt=elt.parentNode)
              {var idx=$(elt.parentNode).children(elt.tagName).index(elt)+1;
               idx>1 ? (idx='['+idx+']') : (idx='');
               path='/'+elt.tagName.toLowerCase()+idx+path;
              }
          return path;
         }

$(document).ready(function() {
    $('*').click(function(event) {
        event.stopPropagation();
        alert(get_XPath(this));
    });
});​

also you will see the demo here: http://jsfiddle.net/CksqX/
