select - Jquery- Get the value of first td in table

I am trying to get the value of first td in each tr when a users clicks "click".

The result below will output aa ,ee or ii. I was thinking about using closest('tr').. but it always output "Object object". Not sure what to do on this one.

My html is

 <table>
   <tr>
      <td>aa</td>
      <td>bb</td>
      <td>cc</td>
      <td>dd</td>
      <td><a href="#" class="hit">click</a></td>
   </tr>
   <tr>
      <td>ee</td>
      <td>ff</td>
      <td>gg</td>
      <td>hh</td>
      <td><a href="#" class="hit">click</a></td>
   </tr>
   <tr>
      <td>ii</td>
      <td>jj</td>
      <td>kk</td>
      <td>ll</td>
      <td><a href="#" class="hit">click</a></td>
   </tr>
</table>

Jquery

$(".hit").click(function(){

 var value=$(this).// not sure what to do here

 alert(value)  ;

});

$(this).parent().siblings(":first").text()

parent gives you the <td> around the link,

siblings gives all the <td> tags in that <tr>,

:first gives the first matched element in the set.

text() gives the contents of the tag.
