instanceof Array

[webaster]

This line throws an error in IE5 MAC.

if (tag instanceof Array). This operator is not implemented in IE 5 MAC

to avoid errors in IE5 MAC - any alternative?

[Bernard Marx]

Usethe constructor property all-round:

if( obj.constructor == Array )

[webaster]

if (typeof(handler) == 'array') {
// do something

}

This is an other option?

[webaster]

if (typeof TreeWalker!== String(undefined) && collection instanceof TreeWalker) {

anyway to replace instanceof here with other operator
