Customized selection tag background color not showing after refresh div tag

I need to refresh my div tag (galleryadv) after ajax post submits to prepare for the next submit. But after submit successfully and refresh, my customized selection tag always changes to the default selection tag. would need some help to resolve my customized selection tag background color, it changes back to the default color instead of black whenever the div refreshes, would appreciate some advice on this, thanks.

index.php

    <script>
         function uploadadv(){

         var catadv = document.getElementById("catadv").value;
         var typeadv = document.getElementById("typeadv").value;
         var countryadv = document.getElementById("countryadv").value;

         var myData = 'catadv='+catadv+ '&typeadv='+typeadv+ '&countryadv='+ countryadv;

         jQuery.ajax({
         type: "POST", // HTTP method POST or GET
         url: "uploadsignupeditadvcheck.php", //Where to make Ajax calls
         dataType:"text", // Data type, HTML, json etc.
         data:myData, //Form variables
         success:function(data){ 

         $('#messageeditcheckadv').html(data);

         },

         error:function (xhr, ajaxOptions, thrownError){
           alert(thrownError);
        }
        });  
        };
