javascript - Make div follow screen wont work -


i trying make text follows screen when u scroll,

i have placed text in div named "mydiv"

<div id="mydiv" >      <!-- lots of stuff in asp -->     <table>         <!-- table rows, etc. -->     </table> </div>

the jquery

<script type="text/javascript"src="http://code.jquery.com/jquery-1.9.1.min.js"></script>  <script type="text/javascript">     $(document).ready(function () {          var currenttop = parseint($('#mydiv').css('top'));         $(window).scroll(function () {             var top = $(window).scrolltop();             $('#mydiv').css('top', top+currenttop);         });      });  </script>

and css

.mydiv{     position:absolute;     top:10px; }

using position: absolute fixes relative body. want position: fixed, fixes relative window.

if have content larger size of box, you'll need account overflow property, have scroll bars on box. user can see of content, though not @ same time of course. css be:

.mydiv {     position: fixed;     top: 10px     overflow: auto;     height: 100%; }

you can drop jquery entirely; don't need long have position: fixed.

note, however, not work mobile browsers, use viewport concept: there view layered on rendered "window" , fixed element locked window, not viewport. in case, need come javascript solution, though preferably 1 fires if on mobile device.
