javascript - getting row index of a specified row using java script -


i want rowindex of passed row number. tried using rowindex[2]. dont it. here code. please me. in advance..

<html>      <head>         <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>   <!-- jquery -->      </head>     <body>         <div id="main">             <button onclick = "replacecontent('tabledata')"> click load  </button>             <table id="tabledata">              </table>                       </div>          <script>              function replacecontent(tableid)             {                 var targetdiv = $('#' + tableid).closest("div").prop("id");                 var content = "<table> <tr> <td> one</td></tr><tr> <td> one</td></tr><tr> <td> one</td></tr><tr> <td> one</td></tr><tr> <td> one</td></tr></table>";                                 $('#' + targetdiv).html(content);                          var x = document.getelementbyid("tabledata").rows[1];                 alert (x.rowindex);             }         </script>     </body> </html>

if have <table id="tabledata"> inside html, there's no need create 1 dynamically, use existent 1 cached element reference.
(also, remember close tag </table>)

function replacecontent(tableid) {        var $table = $("#"+ tableid);        // don't put <table> inside content    var content = "<tr><td> one</td></tr><tr> <td> two</td></tr><tr> <td> three</td></tr><tr> <td> four</td></tr><tr> <td> five</td></tr>";            $table.html(content);             var x = $table.find("tr").eq(1);   // second row html test    alert (x.html());    }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <div id="main">    <button onclick="replacecontent('tabledata')"> click load  </button>    <table id="tabledata"></table>                </div>
