You can Combine here event and this(element)

function postBackByObject(e,d) {
            var target = e.target || e.srcElement;     // Support IE6-8

            if (d.id == 'uploadControl') {

                document.getElementById('labelId').click();
            }
            target.cancelBubble = true;
        }
