Hi,
I've been trying to use Netscape's debugger to examine
the following code (clipped for brevity):
function MM_findObj(n, d)
var p,i,x;
if(!d) d=document;
.....
....
}
The function MM_findObj is called using:
MM_findObj(a[i])
So, the 2nd variable to the function (MM_findObj)
which is "d", is not passed. The line
if (!d) d = document;
should then change "d" from null to the value of the
document.
When I examine the variable "d" within the javascript
debugger, it's value, even after the above code is
executed, never changes. I try to inspect the value
of "d" and it always null.
Why is this so?
TIA,
Dave
