currentAttr

object currentAttr extends AttrHelper[Box]

Used to get an attribute by its name from the current snippet element. There are several means to getting attributes:

  // Get a Box for the attribute:
  val myAttr = S.currentAttr("test") openOr "Not found"

  // Get an attribute or return a default value:
  val myAttr = S.currentAttr("name", "Fred")

  // Apply a transform function on the attribute value, or return an Empty:
  val pageSize = S.currentAttr("count", _.toInt) openOr 20

  // There are also prefixed versions:
  val prefixedAttr = S.currentAttr("prefix", "name") openOr "Not found"

Note that this uses the data held in S.currentAttrs, which means that it will only find attributes from the current snippet element. For example, given the snippets:

<lift:MyStuff.snippetA foo="bar">
  <lift.MyStuff.snippetB>...</lift.MyStuff.snippetB>
</lift:MyStuff.snippetA>

Calling S.currentAttr("foo") from snippetB will return Empty.
