// for writing Cookie
var stringCookie = "<span class='backLinkText1'><img src='../images/deleteImg.png' alt='' class='backLinkDeleteButton' onClick='deleteBackLink()'/></span><a class='backLinkText' href=\""+pathname+"\"> Patient History For \""+patientName+"\"</a>"+cookieTimeVal;
jQuery.cookie('PCC_Back_Button', stringCookie , { expires: 1 });

jQuery('#backButtonSpan').append(
