How to expand iframe or Frameset onMouseOver?

[expertboy]

i create personal website which has two vertical Frames and frames have two different links so, i wana know how to expand iframe or Frameset onMouseOver?

i wana code when i mouseover on left frame then right frame automatically collapse(width=20%) and when i mouseover on right frame then left frame automatically collapse(20%).

Try
<script type='text/javascript'>

var _gotdata ;

function mouseover()
{
_gotdata = document.getElementById( "iframe" )
_gotdata.style.width = 100%;
_gotdata.style.height = 120%;
_gotdata = document.getElementById( "iframe2" )
_gotdata.style.width = 100%;
_gotdata.style.height = 80%;
}

function mouseout()
{
_gotdata = document.getElementById( "iframe" )
_gotdata.style.width = 100%;
_gotdata.style.height =80%;
_gotdata = document.getElementById( "iframe2" )
_gotdata.style.width = 100%;
_gotdata.style.height =120%;
}

</script>

<iframe style='width:200px;height:200px' src='http://google.com' onmouseover='mouseover()' onmouseout='mouseout()' id='iframe'></iframe>
But with several frames instead im not sure if you can just use the 20 % though.

without % sign it works.

_gotdata.style.width = 100%;
_gotdata.style.height = 120%;

problem, when i mouseOver on any 1 frame they both expand at once.
