Drag and Drop in ASP.Net

Question

I want to get the value of label LabRef and pass to Ajax function for processing. At moment i am retrieving value of hidden field from draggable div inside Repeater control but now need to pass the label value also.

function OnDragStart(e) {

    e.dataTransfer.effectAllowed = 'move';

    e.dataTransfer.setData('text', $(this).find('HiddenField[ID*="HiddenField1"]'));
}
function OnDrop(e) {
  

 $(this).append("<div class='selectedproduct' data-product-name='" + e.dataTransfer.getData('text') + "'>" + e.dataTransfer.getData('text') + "</div>");

        var data = new Array(1);
        $("#img1 div").each(function (index) {
            data[index] = "'" + this.innerHTML + "'";

        });

        function sendMyAjax(URL_address) {
            $.ajax({
                type: 'POST',
            
                url: URL_address,
                contentType: "application/json; charset=utf-8",
                data: '{products:[' + data.join() + ']}',
                dataType: 'json',
                success: function (results) { alert(results.d); },
                error: function () { alert('error'); }
            }); return false;
        };

}
