在该人选择隐藏div之后，如何使div重新出现？ （与javascript相关）

Question

So I am javascript illiterate, but I did find this useful code online:

<script type="text/javascript">
function readCookie( cName )
{
  var v;

  return decodeURIComponent( ( v = ( document.cookie || "" ).match( "(^|\\s)" + cName + "=([^;$]+)" ) ) ? v[ 2 ] : "" );
}

function setCookie( cName, cValue, life, cPath, cDomain, cSecure )
{
 var dt = new Date(), 
     expSecs = ( expSecs = life.toString().match( /\bsecs\s*=\s*(\d+)/i ) ) ? Number( expSecs[ 1 ] ) : 0,
     params = ( life ? ( ";expires=" + new Date( expSecs ? ( dt.setTime( dt.getTime() + expSecs * 1000 ) )                                                          : ( dt.setDate( dt.getDate() + life) ) ).toUTCString() ) : "" )
            + ( cPath ? (";path=" + cPath) : "" )
            + ( cDomain ? ";domain=" + cDomain : "" )
            + ( cSecure ? ";secure" : "" );

 document.cookie = cName + "=" + encodeURIComponent( cValue ) + params;

 return readCookie( cName );
}

if( readCookie( "close" ) )
{
  document.getElementById("thing").style.display="none";
}

function close_thing()
{
  document.getElementById("thing").style.display="none";
  setCookie( "close", "true", 20 );
}
</script>

It works with this div

<div id="thing">
<div id="close_stuff" onclick="close_thing();"><a href="#">Close this</a></div>
</div>

My problem is, if I want my div to contain content, which the user can close if he/she wishes. However, I want the div to reappear, when I put new content into the div.

Is there a way I could do this manually? Like rename all the "close_thing" to "klose_thing", or something?

Thanks!

Adding another function will do this for you. Set the display property to block.

function show_thing()
{
  document.getElementById("thing").style.display="block";
}

Then call show_thing function display the div again.
