7:52 pm on May 30, 2006 (utc 0) Hello,
Could somebody tell me what the following script does?
<script language="JavaScript">
<!-- function SymError()
{
return true;
} window.onerror = SymError; function SymInitWinOpen()
{
if (SymRealWinOpen == null)
SymRealWinOpen = window.open;
return SymWinOpen;
} function SymWinOpen(url, name, attributes)
{
return (new Object());
} var SymRealWinOpen;
window.open = SymInitWinOpen(); //-->
</script> Thanks for any help.

function SymError()
{
return true;
} window.onerror = SymError; |
|
This part will suppress all JavaScript errors, not sure why you would want to do that, I think most browsers by default will not show errors ? The remaining code is replacing the window.open function with do nothing code (return new empty object), perhaps trying to prevent popups ?

Thank You very much. I will delete it. Was added by someone else. Can you explain what this does?

The FP_ prefix is used by FrontPage, but look at the function names. That should give you a clue. Tom

This scripting is automatically added by Norton Security. That is, as "ordinary" web pages load, Norton adds it on the fly. previous thread among many [webmasterworld.com] The second one is almost a direct rip from Macromedia's/Adobe's preload and mouseover functions, in fact, it sure looks like someone has renamed them - usually they start with MM_ and it has all been changed to FP_. It is designed to preload mouseover images and manage the mouseovers.

Thank You.
Expression Web says hyperlink "gdsImageSwapping.js" broken on each of the 4 pages in the site. Can't figure it out. May just delete it.
Thanks,
Admiral
