javascript - Get nested div using document.getElementById -


given following html file,

<html>   <head>      <script>         function initialize() {            document.getelementbyid('id2')         }       </script>   </head>   <body>     <div id="id1">        <div id="id2"></div>      </div>   </body> </html>

i access inner div tag using 

document.getelementbyid

function in html header, which, although read contrary, not seem work (in safari 6.0.5.), while works access outer tag.

here have fiddle shows works. script needs called after element created.

<body>     <div id="id1">         <div id="id2"></div>     </div>     <script>alert(document.getelementbyid('id2'));</script> </body>

or:

<body>     <script>         function getelement (id) {             return document.getelementbyid(id);         };     </script>     <div id="id1">         <div id="id2"></div>     </div>     <script>alert(getelement('id2'));</script>  </body>
