My website uses a javascript code to open a popup window when someone clicks on a graphic. This works fine in IE, but not in Firefox. Firefox gives an error 404 page not found error in the popup. I have all the options in Firefox set to accept popups, etc.

here is an url to show you what happens-

That is a problem with the JavaScript that opens the popup. The script uses href, but for an image that should be src instead. Apparentlt IE doen't care about the missing href and uses the src instead.

function popup(mylink, windowname)
{
if (! window.focus)return true;
var href;
if (typeof(mylink) == 'string')
   href=mylink;
else
   href=mylink.href;
window.open(href, windowname, 'width=800,height=400,scrollbars=yes');
return false;
}

This should work:

function popup(mylink, windowname)
{
if (! window.focus)return true;
var href;
if (typeof(mylink) == 'string')
   href=mylink;
else
   href=mylink.href || mylink.src;
window.open(href, windowname, 'width=800,height=400,scrollbars=yes');
return false;
}

Thank you so much for taking the time to reply. However, it didn't work. I added your code and I'm still getting a 404 error code. Here's a test page you can see:

If you look at the page source then you will notice thatsomething went wrong with pasting the code and that all white space got removed causing elsehref to become one word: elsehref
So you need to fix the white space in the JavaScript code.


function popup(mylink, windowname){if (! window.focus)return true;var href;if (typeof(mylink) == 'string')href=mylink;
elsehref=mylink.href || mylink.src;
window.open(href, windowname, 'width=800,height=400,scrollbars=yes');return false;}

(I see that you discovered that yourself and have fixed it)
