I'm trying to get my head around this method and I'm getting results
unexpected results. I'm trying to get the index number of the th's that
have the '.asc' class. Any ideas why the second one is returning -1 ?
Thank you! :)
<html>
<head>
<script src="jquery.js" type="text/javascript"></script>
<script>
$(document).ready(function() {
$("table.simple").each(function() {
var x = $('th',this).index($('.asc')[0]);
alert(x);
//first returns 2, as expected
//second returns -1, should it be 0?
});
});
</script>
</head>
<body>
<table class="simple">
<thead>
<tr>
<th>Column 1</th>
<th>Column 2</th>
<th class="asc">Column 3</th>
</tr>
</thead>
<tbody>
<tr>
<td>Data 1</td>
<td>Data 2</td>
<td>Data 3</td>
</tr>
</tbody>
</table>
<table class="simple">
<thead>
<tr>
<th class="asc">Column 1</th>
<th>Column 2</th>
<th>Column 3</th>
</tr>
</thead>
<tbody>
<tr>
<td>Data 1</td>
<td>Data 2</td>
<td>Data 3</td>
</tr>
</tbody>
</table>
</body>
