獲取cookie

function getCookie (name){
    var search = name + '=' //查詢檢索的值
       if(document.cookie.length > 0) {
         var sd = document.cookie.indexOf(search)
         if (sd != -1) {
           sd += search.length
           var end = document.cookie.indexOf(';', sd)
           if(end === -1
 
) {
             end = document.cookie.length;
           }
           return  document.cookie.substring(sd, end)
         }
       }
       return ''
}
