<table width="600px" id="project">             <tr>                 <td>1</td>                 <td><textarea name="pro_1" cols="100" rows="2"></textarea></td>             </tr>             <tr>                 <td>2</td>                 <td><textarea name="pro_2" cols="100" rows="2"></textarea></td>             </tr>             <tr>                 <td>3</td>                 <td><textarea name="pro_3" cols="100" rows="2"></textarea></td>             </tr>             <tr>                 <td>4</td>                 <td><textarea name="pro_4" cols="100" rows="2"></textarea></td>             </tr>             <tr>                 <td>5</td>                 <td><textarea name="pro_5" cols="100" rows="2"></textarea></td>             </tr>          </table>          <input id="addbtn" type="button" name="addbtn" value="add">

this jquery code:

        $(document).ready(function() { $("#addbtn").click(function(){     var num=parseint($("#project tr:last").text());         num+=1;             $("#project,textarea").append("<tr><td>"+num+"</td><td><textarea cols='100' rows='2'></textarea></td></tr>");                 });  $("#pub_addbtn").click(function(){     var val=parseint($("#pub tr:last").text());         val+=1;              $("#pub,textarea").append("<tr><td>"+val+"</td><td><textarea cols='100' rows='2'></textarea></td></tr>");                 });

});

sorry table here:

<table width="600px" id="pub">             <tr>                 <td>1</td>                 <td><textarea name="pub_1" cols="100" rows="2"></textarea></td>             </tr>             <tr>                 <td>2</td>                 <td><textarea name="pub_2" cols="100" rows="2"></textarea></td>             </tr>             <tr>                 <td>3</td>                 <td><textarea name="pub_3" cols="100" rows="2"></textarea></td>             </tr>             <tr>                 <td>4</td>                 <td><textarea name="pub_4" cols="100" rows="2"></textarea></td>             </tr>             <tr>                 <td>5</td>                 <td><textarea name="pub_5" cols="100" rows="2"></textarea></td>             </tr>          </table>         <input type="button" name="pub_addbtn" value="add" id="pub_addbtn">

just use index()... , have fixed of selectors. http://jsfiddle.net/yhkrt/

assuming have 2 tables , 2 buttons there issues code caused issue. code fixes it.

$("#addbtn").click(function () {      var num = parseint($("#project tr:last").index()) + 1;     num += 1;     $("#project").append("<tr><td>" + num + "</td><td><textarea cols='100' rows='2'></textarea></td></tr>"); });  $("#pub_addbtn").click(function () {      var val = parseint($("#pub tr:last").index()) + 1;     val += 1;     $("#pub").append("<tr><td>" + val + "</td><td><textarea cols='100' rows='2'></textarea></td></tr>"); });
