Display a sessionStorage item

I want to display the field player but i can't:

<body>

       <header>
    <h1>My memory Game</h1>
</header>

<div id="timer">
    Player Name: 
    <span id="player-name">

               <script type='text/javascript'>

                sessionStorage.getItem('player');

                //alert("Your name is: " + sessionStorage.getItem('player'));    

               </script>    
    </span>
</div>

When i test it by using javascript alert everything work : the player name is desplayed without a problem Any idea please

Solution

Use this:

document.getElementById('player-name').innerHTML = 
     sessionStorage.getItem('player');

Fixed code:

<body>
    <header>
        <h1>My memory Game</h1>
    </header>
    <div id="timer">
        Player Name: 
        <span id="player-name">
        </span>
    </div>
    <script type='text/javascript'>
        document.getElementById('player-name').innerHTML = sessionStorage.getItem('player');
    </script>

You should do some javascript tutorials.
