Answer 1

For example, this should work

window.frameElement.name

Also, if all you have is a reference to an element inside a frame and want to know the frame name this element belongs to:

document.getElementsByTagName("body")[0].ownerDocument.defaultView.window.frameElement.name

Answer 2

Why are all the answers here so complicated ?

The name of the current document (== frame name) can be obtained via:

var sName = window.name;

If the current document is the root document or if the parent document has not assigned a name to the child frame, sName will be an empty string.
