Help with OBJECT DOESN"T SUPPORT

[Paul Reed]

Hello,

I have a function that runs at load time and throws a an "Object Doesn't
Support This Propertiy or Method" jscript error.

The offending line is "if (type != "undefined" ) ". If I change the check to
"type != """...I get no error...any ideas?

var thePath = "";
var type = ""
var type = typeof parent.ory_butt on;
if (type != "undefined" ) {
type = typeof parent.ory_butt on.getTreePath( );
if (type != "undefined" ) {
thePath = parent.ory_butt on.getTreePath( );
}
}
document.write( thePath);

Comment: defining the same variable twice is not useful. Simply omit the
first declaration assigning the null string.

This line is calling the getTreePath method instead of ascertaining if
it exists. Try
type = typeof parent.ory_butt on.getTreePath; // then:[color=blue]

Alternatively, try:

var thePath = "";
if(parent.ory_b utton && parent.ory_butt on.getTreePath)
thePath = parent.ory_butt on.getTreePath( );
document.write( thePath);
