Generate id for row in JSF datatable
I am trying to achieve the expand/contract functionality of table rows in JSF using core faces implementation. As answered in one of my earlier thread this is not straight forward to achieve in core faces implementation. So, I thought of using HTML + jQuery to achieve the functionality. I am calling the row with +/- gif as parent row and the rows that are to be expanded and contracted are its child rows. To make parent row aware of which child it needs to show or hide, I am making use of jquery and assigning row id to each <tr>. If the parent row-id="row1234", then the child row will have row-id="row1234-child".
Below is the Jquery Script and HT开发者_JAVA百科ML code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

<html>
<head>
<script src="jquery.js"></script>
<script>
$(document).ready(function(){
$('.expand').click(function() {
if( $(this).hasClass('.hidden') )
{
$(this).attr("src", "plus.gif");
}
else
{
$(this).attr("src", "subtract1.gif");
}
$(this).toggleClass('hidden');
$(this).parent().parent().siblings('#'+$(this).parent().parent().attr('id')+'-child').toggle();
});
});
</script>
<style>
.hover {background-color:#00f; color: #fff;}
</style>
</head>
<body>
<table border="1" cellspacing="0" cellpadding="0">

<tr><th>Rolling </th><th>transaction</th></tr>

<TR class="parent" id="row123" style="cursor: pointer; " title="Click to expand/collapse">

<TD>100</TD>
</TR>
<TR ID="row2345-child" style="display: none; ">

<TD>40</TD>
</TR>
<TR class="parent" id="row3456" style="cursor: pointer; " title="Click to expand/collapse">
<TD>345</TD>
<TD colspan="2">HIJ</TD>
<TD>100</TD>
</TR>
</tbody>
</table>
</body
</html>
So, I was wondering whether I can generate row id for datatable or if there is a better solution for it.
