Живой но банальный пример:
Код:
<img id="TheImage" src="http://img166.***************img166/7742/pagegeneralxi0.th.jpg" border="0"/>
<script language="JavaScript">
<!--
function xbGetWindowWidth(windowRef)
{
var width = 0;
if (!windowRef) windowRef = window;
if (typeof(windowRef.innerWidth) == 'number') width = windowRef.innerWidth;
else if (windowRef.document.body && typeof(windowRef.document.body.clientWidth) == 'number') width = windowRef.document.body.clientWidth;
return width;
}
function xbGetElementById(e)
{
if(typeof(e)!='string') return e;
if(document.getElementById) e=document.getElementById(e);
else if(document.all) e=document.all[e];
else e=null;
return e;
}
function on_window_resize(e)
{
var v_window_width=xbGetWindowWidth();
var o = xbGetElementById('TheImage');
if (o) o.width=v_window_width;
}
window.onresize = on_window_resize;
on_window_resize(null);
// -->
</script>
