Hi,

Our webpage uses the following JavaScript code.

function toggleSubmenu(divId, link)
{
var div = document.getElementById(divId);
div.style.display = (div.style.display == 'block') ? "none" :
"block";
if (link.className == "")
link.className = "tempselected";
else
link.className = "";
}

Launching the page in IE pops up the error:

A runtime error has occurred. Do you wish to debug? Line:188
Error: Object required

The line reporting error is:

div.style.display = (div.style.display == 'block') ? "none" : "block";

The version of IE I tested is 6.0.2900.2180.xpsp-sp2-gdr.050301-1519.

The page does not return any errors in other browsers (e.g. Firefox,
Netscape, etc.)

How should I fix the error?

Any help would be greatly appreciated.

Try:
div.style.display=div.style.display=="none"?"":"none";

Google: "ternary operator", or "conditional operator".
