Read runtime generated controls using classname with JQuery

 $('.ClassName').live('click', function (e) {
        e.preventDefault();
        //  blockScreen(this.id);
        var indexid = this.id.split('-');
        var name = this.name;
         $('ID').html("<image style=' margin-top:35px; padding-bottom:40px' src='images/loaderNew.gif' alt='Loading' ></image>");
        $.ajax({
            type: "POST",
            url: "ABC.aspx",
            data: { cIndex: indexid[1], Details: details },
            success: ShowPopup,
            error: function (XMLHttpRequest, textStatus, errorThrown) {
                //error message
            }
        });
    });

function ShowBookNowPopup(resp) {
        $(blockId).html(resp);
        $(blockId).show();

    }

Load result on scroll using jquery.

JAVASCRIPT : 

var sIndex = 10, offSet = <%=offSet %>, isPreviousEventComplete = true, isDataAvailable = true;
$(document).scroll(function () {
        if ($(document).height() - 50 <= $(window).scrollTop() + $(window).height()) {
            $('#loadMsg').hide();
            if (isPreviousEventComplete && isDataAvailable) {
                isPreviousEventComplete = false;
                $('#loadMsg').show();              
                $.ajax({
                    type: "GET",
                    url: 'ResultAjax.aspx?startIndex=' + sIndex + '&offset=' + offSet + '',
                    success: function (result) {
                        $("#result").append(result);
                        $('#loadMsg').hide();
                        sIndex = sIndex + offSet;
                        showFltrdResult();
                        isPreviousEventComplete = true;

                        if (result == '') { //When data is not available
                            isDataAvailable = false;
                            $('#loadMsg').hide();
                        }
                    },
                    error: function (error) {
                        $('#loadMsg').hide();
                        alert(error);
