How can I refresh Google Map Marker and Map with existing Data when page is reloaded?

Question

I need a way to refresh and reload my Google Map and Marker with data that was previously saved. Essentially, I want to be able for a user to Autocomplete an address, store the information's lat, long, and place_id from the query, and then if they return to the page again, reload the map with the most recent search marker and map image.

 $('#jobLoadingAddressLat').val(place.geometry.location.lat())
 $('#jobLoadingAddressLng').val(place.geometry.location.lng())
 $("#jobLoadingAddressID").val(place.place_id);

This is what I am using to parse the the Map info. Is there a way for me to use this information to reload the map and marker when the user returns to the page?

Will storing the information in a cookie be the best option? What do you guys recommend? Thanks in Advance.

            function codeAddress() {

                // alert("hizo click ....!!!!")
                // We obtain the address and assign it to a variable
                if (document.getElementById("fPersonal:inputDir").value.length > 0) {
                    // alert("Direccion mayor a 0");
                    var combo;
                    var selectValue;
