- # Returns a button with the given +name+ text that'll trigger a JavaScript +function+ using the
- # onclick handler.
+ # Returns a button whose +onclick+ handler triggers the passed JavaScript.
#
- # The first argument +name+ is used as the button's value or display 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"
+ # The helper receives a name, JavaScript code, and an optional hash of HTML options. The
+ # name is used as button label and the JavaScript code goes into its +onclick+ attribute.
+ # If +html_options+ has an <tt>:onclick</tt>, that one is put before +function+.
#
- # 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
+ # button_to_function "Greeting", "alert('Hello world!')", :class => "ok"
+ # # => <input class="ok" onclick="alert('Hello world!');" type="button" value="Greeting" />
#
- # Examples:
- # button_to_function "Greeting", "alert('Hello world!')"
- # button_to_function "Delete", "if (confirm('Really?')) do_delete()"
- # button_to_function "Details" do |page|
- # page[:details].visual_effect :toggle_slide
