- # Returns a link of the given +name+ that will trigger a JavaScript +function+ using the
- # onclick handler and return false after the fact.
- #
- # The first argument +name+ is used as the link text.
- #
- # The next arguments are optional and may include the javascript function definition and a hash of html_options.
- #
- # The +function+ argument can be omitted in favor of an +update_page+
- # block, which evaluates to a string when the template is rendered
- # (instead of making an Ajax request first).
- #
- # The +html_options+ will accept a hash of html attributes for the link tag. Some examples are :class => "nav_button", :id => "articles_nav_button"
- #
- # Note: if you choose to specify the javascript function in a block, but would like to pass html_options, set the +function+ parameter to nil

- # link_to_function "Greeting", "alert('Hello world!')"
