with infinite ul li level

$('a.level').click(function(){

  return(false);
}

Thank you.

The element hierarchy in your markup makes it a little complicated, but you can walk up the <ul> ancestor chain with parents() and fetch the anchor elements you're interested in with prev().

From there, you can map() the text content of these elements and join() the resulting array into an absolute path:

$("a.level").click(function() {
    alert($(this).parents("ul").prev("a.level").add(this).map(function() {
        return $(this).text();
    }).get().join("/"));
});

You can see this solution in action in this fiddle.

$('a.level').click(function(){
  $(this).parents("a.level");
}

$('a.level').click(function(){
  var tempString = '';
  for(var i=0;i<$(this).parents('.level').length;i++){
      tempString += $(this).parents('.level').get(i).text + "/";
  }
  tempString += $(this).text;
  alert(tempString);
}
