How do I retrieve a value from local storage and set it in an HTML input field?

I am building a prescription maker. But I am facing a problem. I want to show to localstorage data in the select box. But I can't. So I need help. Actually i just need a function that detects my row index of table and print the data according to the index in the input field. Thanks in advance

function editpres(){   
        var aha = JSON.parse(localStorage.getItem('books'));

        document.getElementById('name').value = aha[0].name;
        document.getElementById('age').value =aha[0].age;
        document.getElementById('sex').value = aha[0].sex;
        document.getElementById('date').value = aha[0].date;
        document.getElementById('disease').value = aha[0].disease;
        document.getElementById('dignosis').value = aha[0].dignosis;

        }

        <html>
        <div>      
            <table class="table table-success table-striped ">
            <thead>
              <tr>
                <th>Patient Name</th>
                <th>Age</th>
                <th>Sex</th>
                <th>Date</th>
                <th>Disease</th>
                <th>Dignosis</th>
                <th>Medicine</th>
                <th>Test</th>
                <th></th>
              </tr>
            </thead>
            <tbody id="book-list"></tbody>
          </table>
        </div>
        </html>
