Interpreting a link statement in "Ajax on Rails"


Hi All,

In Chapter 2, the author adds the following line to create a hyperlink
in app/views/chapter2/myaction.rhtml:

Inline alert()

Without the href clause, the text “Inline alert” would be rendered
merely as plain text rather than as a hyperlink, so there would be
nothing to click on to raise the “onclick” event.

But the ‘="#"’ portion of that clause seems to be superfluous, at
least in my Firefox browser, ver. If the subject portion is
not superfluous, how is it to be interpreted?
