how to limit the additions field?

[sjns]

Hi,

If someone here is willing to help me I would really appreciate

 

how to limit the addition of columns in the following html code, let say only up to 5 only?

Code:

 

<script type="text/javascript"><!--

function addFriend() {

var tbl = document.getElementById('my_friends');

var iteration = tbl.tBodies[0].rows.length;

newRow = tbl.tBodies[0].insertRow(-1);

var newCell = newRow.insertCell(0);

newCell.innerHTML = '<?php echo $entry_friend; ?>';

var newCell1 = newRow.insertCell(1);

var el = document.createElement('input');

el.type = 'text';

el.name = 'friends[]';

el.size = 30;

el.maxlength = 45;

newCell1.appendChild(el);

// if (newCell > 2) tbl.addCell(newCell + 1);

}

 

function removeFriend() {

var tbl = document.getElementById('my_friends');

var lastRow = tbl.rows.length;

if (lastRow > 2) tbl.deleteRow(lastRow - 1);

}

//--></script>

 

Thanks in advance
