    To retain the selected value in the dropdown on refresh, sessionStorage is used to store the value within the user's browser. First, the values have to be set using sessionStorage.setItem("SelItem", selVal); SelItem is a variable in which we are setting the value of selVal . Now, we can get the value using sessionStorage.getItem("SelItem") after page refresh.

    Example:

    index.html

    <select id="sort-item">
                 <option value="Alphabetical" data-sort="1">Alphabetical</option>
                 <option value="low to high" data-sort="2">Low to High Price</option>
                 <option value="high to low" data-sort="3">High to Low Price</option>
    
     </select>
    

    abc.js

    window.onload = function() {
        var selItem = sessionStorage.getItem("SelItem");  
        $('#sort-item').val(selItem);
        }
    
        $('#sort-item').change(function() { 
            var selVal = $(this).val();
            sessionStorage.setItem("SelItem", selVal);
        });
