เอาเม้าส์วางที่ Tab แล้วไม่โชว์ ลิงค์ตรับ ทำอย่างไรครับ

<script src="http://code.jquery.com/jquery-1.7.2.min.js"></script>
<script>
$(document).ready(function() {
    $("#content").find("[id^='tab']").hide(); // Hide all content
    $("#tabs li:first").attr("id","current"); // Activate the first tab
    $("#content #tab1").fadeIn(); // Show first tab's content
    
    $('#tabs a').click(function(e) {
        e.preventDefault();
        if ($(this).closest("li").attr("id") == "current"){ //detection for current tab
         return;       
        }
        else{             
          $("#content").find("[id^='tab']").hide(); // Hide all content
          $("#tabs li").attr("id",""); //Reset id's
          $(this).parent().attr("id","current"); // Activate this
          $('#' + $(this).attr('name')).fadeIn(); // Show content for the current tab
        }
    });
});
</script>
