Without any description of what happens, or what should happen, just dumping some script and expecting answers is not going to work.

Dear Pritaeas

There is a link with class(<a class="countryclassinfolink" href="#">Advanced DNA</a>)
on click on it all data of next element will be copy and append in div(id='country_details')

But it is not work

I think you should bind the click event in the document ready event. Looks like you are executing your code too early.

hai vishal.du123,

as pritaeas said, please make your script code from this

<script>$('.countryclassinfolink').click(function(event) {
event.preventDefault();
var detailinfo = $(this).parent().next().html();
$('#country_details').html(detailinfo);
$('.countryclassinfolink2').click(function(event) {
event.preventDefault();
$('#country_details').html('');
$('#country_details').hide();
$('#country_seminars').fadeIn();
});
$('#country_seminars').hide();
$('#country_details').fadeIn();
});
</script>

to this

<script type="text/javascript">
$(document).ready(function(){

$('.countryclassinfolink').click(function(event) {
    event.preventDefault();
    var detailinfo = $(this).parent().next().html();
    $('#country_details').html(detailinfo);
    $('.countryclassinfolink2').click(function(event) {
            event.preventDefault();
            $('#country_details').html('');
            $('#country_details').hide();
            $('#country_seminars').fadeIn();
    });
    $('#country_seminars').hide();
    $('#country_details').fadeIn();
});
});

</script>

you missed $(document).ready() function to initiate the your desired ccall

thats it

happy coding
