var topcell = false;
cells.each(function ()
{
var $cell = $(this);
if ($cell.hasClass('csstdhighlight'))
{
if (i == 0)
{
$cell.find('span').text(jQuery('#<%=txtPatientName.ClientID%>').val());
topcell = $cell;
}
else
{
$cell.remove();
}
i++;
}
});
if (topcell && i > 1) topcell.attr('rowspan', i);
$("#tableAppointment tr").each(function ()
{
$('td', this).each(function ()
{
var value = $(this).find("span").val();

Reset to default 6if($('span').text().length == 0){
console.log('No Text');
}
else{
console.log('Has Text');
}
Demo: http://jsfiddle.net/hj4Bt/1/
Use $(this).find("span").text() instead. Check if the returned string is empty.
Instead of this
var value = $(this).find("span").val();
write
var value = $(this).find("span").text();
and if you want to check html inside span then use
var value = $(this).find("span").html();

Is that what you want?
See demo: http://jsfiddle.net/FDEep/3/
$('input').click(function(){
// All <span> inside <td>
$('td span').each(function(index){
// Check if 'span' is empty
if( $(this).text().length !== 0 ){
// Change the bg color of the 'span' not empty
$(this).parent().css('background-color', 'yellow');
// When a span with some value is found, alert the index of the row
alert( $(this).closest('tr')[0].rowIndex);
}
});
});

$('#tableAppointment tbody tr td:nth-child(3)')returns only one element and using each is redundant. – Ram Commented Jun 14, 2012 at 7:42
