Constructor Details

#initialize(name, close_type = nil) ⇒ Tag

A tag currently has only two attributes: a name and a method for closing it, which both decide how it is rendered as a string. A self-closing tag:

Tag.new('test', :self).render # => "<test />"

A tag that does not need to close:

Tag.new('test', :none).render('test this') # => "<test>test this\n"

And a regular tag:

Tag.new('test').render # => "<test></test>"

Instance Method Details

#render(inside = nil, opts = {}) ⇒ Object

Generates a string from this tag. inside should be the contents to put between the opening and closing tags (if any), and opts are the HTML options to put in the tag. For example,

Tag.new('div').render('Click for an alert.', 
                      :onclick => "alert('Hi.');")

gets you this:

<div onclick="alert('Hi.');">Click for an alert.</div>
