    http://datatables.net/api#fnGetData ? Pass it the TR element you want the data for and it gives you an array.

    Hello,

    It seems that the :
    [code]$('#example2 tbody td').click( function () [/code]

    is not catched for an ajax source, that one is catched :

    [code]
    $('#example2 thead th').click( function () {
    alert ('click');
    } );
    [/code]

    Regards,
    Lionel.

    Yeaah !

    I have found a way to do so, using the livequey plugin :

    Actually i needed to get the value of all first TD when clicking on them :

    [code]
    $('#example2 tbody td:first-child').livequery('click', function(event) {
    $('#idselect2').val(this.innerHTML);
    } );
    [/code]

    Regards

    This brings up an interesting thought, instead of using a function before draw to go back and loop through to add the click event, it seems that using a live binder to the column would be simpler and possibly less overhead.

    Do I understand this correctly?

    Thanks,

    Yup - live events are a great way to do this. I do like them :-)

    Another option is to use fnGetNodes() ( http://datatables.net/examples/advanced_init/events_post_init.html ). And possibly fnDrawCallback.

    Actually it does not work properly,

    when i have many rows, and if i click on the "next" button to display following rows, it still works, but when i click on "previous" the livequery stops working.

    Regards.

    Fixed !

    I switch from livequery plugin to native live :
    [code]
    $('#example tbody td:first-child').live('click', function() {
    $('#idselect').val(this.innerHTML);
    });

    $('#example tbody td:first-child').live('mouseover mouseout', function(event) {
    if (event.type == 'mouseover') {
    $(this).addClass('dessus');
    } else {
    $(this).removeClass('dessus');
    }
    });
    [/code]
