this javascript is not working in chrome but works in ie

<script language="javascript">


function switchScreen(v)
{

if(v=='d')
{
    mf.rows="0,*";
    window.frames.topFrame.location='blank.htm';

}
else
{
    mf.rows="*,0";
    window.frames.topFrame.location='http://sample.htm';


}


}



</script>


<frameset name="mf" id="mainFrame" rows="*,0" frameborder=no framespacing=0>
<frame name='topFrame' id="tp" src='http://sample.htm/' scrolling="no" frameborder=0 noresize marginheight=0 marginwidth=0>
<frame name='bottomFrame' id="bp" src='Main.html' scrolling="no" frameborder=0 noresize  marginheight=0 marginwidth=0>
</frameset>

The开发者_如何学Go function is called from within the bottom frame

In this case, mf will be available in Internet Explorer only, because that browser has the "feature" of adding all DOM elements with a name to the window object.

Add

mf = document.getElementById("mainFrame");

to the top of the script and it will work.

By the way, to see JavaScript errors in Chrome, press Ctrl + Shift + J and then the "Console" tab. Every browser has a JavaScript error console, which should always be the first port of call when something doesn't work; it's just a bit hidden sometimes.
