javascript - Is there a way to check if two DOM elements are equal?

Question

It's no problem to find an element by position and the position of an element in Javascript. But is there are general way to compare them?

The only way I could think of is comparing ids or classnames, but not all elements have ids or classnames.

Answer 1

In modern browsers there are two methods for comparing nodes.

var a = document.createElement('div');
var b = document.createElement('div');
b.isEqualNode(a); // true

but

b.isSameNode(a); //false

And as for IE, it's DOM elements have non-stanard attribute, uniqueID. But I can't imagine it can be useful in this case, since yes, you actually can compare two pointers.
