count the number of rows in the table

crmpicco · January 28th, 2005, 08:35 AM

I would like to be able to write a function (or something) to count the number of rows in the table, I don't know how to do it, any help is appreciated.

Look under DHTML Objects for table and look at its collections.

Hi,

I have not tried this but I think that is the way to do it.

function getTables()
{
    var arrTables = document.getElementsById("tableID");
    var oRows = arrTables.rows;
    alert(oRows.length)
}

yep it works ... just tried out a sample and here is the code ...

<html>
<head>
<script language="javascript">
   function countTableRows()
   {
     var rows=document.getElementById("tbl").rows.length;
     alert(rows);
   }
</script>
</head>
<body>

<table id="tbl">
   <tr><td>Row 1</td></tr>
   <tr><td>Row 2</td></tr>
   <tr><td>Row 3</td></tr>
   <tr><td>Row 4</td></tr>
</table>
<input type="button" value="count" onClick="javascript:countTableRows()">

</body>
</html>
