Rendering

• simple rendering

  import com.astamuse.asta4d.scala.R._
  def render(): Renderer = {
    "#someIdForInt" -> 12345 &
    "#someIdForLong" -> 12345L &
    "#someIdForBool" -> true &
    "#someIdForStr" -> "a str" &
    "#someIdForNull" -> (null.asInstanceOf[Object]) &
    "#someIdForClear"-> Clear &
    "#someIdForElementSetter" -> new ChildReplacer("<div></div>".parseAsSingle()) & 
    "#someIdForElement" -> "<div>eee</div>".parseAsSingle() &
    "#someIdForRenderer" -> ("#value" -> "value") &
    "#someIdForRenderable" -> (()=>("#id" -> "xx").asRenderer())
  }

• list rendering

  import com.astamuse.asta4d.scala.R._
  def render() = {
    "#someIdForRenderer" -> List(123, 456, 789).map { i => {
      "#id"-> ("id-" + i) & "#otherId"-> ("otherId-" + i)
    }}
  }

  import com.astamuse.asta4d.scala.R._
  def render() = {
    "#someIdForInt" -> List(123, 456, 789) &
    "#someIdForLong" -> List(123L, 456L, 789L) &
    "#someIdForBool" -> List(true, true, false) &
    "#someIdForStr" -> List("str1", "str2", "str3") &
    "#someIdForElementSetter" -> 
      List(new ChildReplacer("<div>1</div>".parseAsSingle()), new ChildReplacer("<div>2</div>".parseAsSingle())) &
    "#someIdForElement" -> List("<div>1</div>".parseAsSingle(), "<div>2</div>".parseAsSingle())
  }

• attr rendering

  import com.astamuse.asta4d.scala.R._
  def render() = { 
    ("#id", "+class") -> "yyy" & // use parentheses to clarify the operation target
    ("#id", "-class") -> "zzz" &
    "#id" -> "+class" -> "xxx" & // use tuple arrow straightaway to simplify input
    "#id" -> "value" -> new Date(123456L) &
    "#id" -> "href" -> null & 
    "#idstr" -> "value" -> "hg" &
    "#idint" -> "value" -> 3 &
    "#idlong" -> "value" -> 3L &
    "#idbool" -> "value" -> true 
    
  }

Test

• list assertion by ScalaTest

  import com.astamuse.asta4d.scala.R._
  val tester = RendererTester.forRenderer(render())
  val testerList = tester.getAsRendererTesterScalaList("#someIdForRenderer")
    
  assert(List("id-123", "id-456", "id-789") === testerList.map(_.get("#id")))
  assert(List("otherId-123", "otherId-456", "otherId-789") === testerList.map(_.get("#otherId")))
