I've to reload another frame:
parent.frames[8].location = "page2.htm";
this scripts is included in all my pages with an .js file

But sometimes there's another frameset and the specific frame does not exists. So the scripts should only work when the frame exists

I tried something like:

if (parent.frames[8].name == 'framename')
     {
     parent.frames[8].location = "page2.htm";
     }

But still get an error when there's no frame 8.

var w = window.open("", "framename");
if(w)
{
   alert("frame is present!")
   w.location = "page2.htm"
}

I don't want to use window.open. If there's no frame[8] just don't run the script, not try to create the page.

I had the script working few months ago, but lost the script. Its was something like

if (parent.frames[8].name == 'framename')
    {
    parent.frames[8].location = "page2.htm";
    }

or

if (parent.frames[8]=true)
    {
    parent.frames[8].location = "page2.htm";
    }
