Scalatags 会生成 HTML 还是 Javascript？

Question

我看到一些似乎生成 HTML...

的 Scala 代码

  def pagePlay: TypedTag[dom.raw.HTMLElement] = div{
    val levels = Array(
      (10, "Easy game; you are allowed 10 misses."),
      (5, "Medium game; you are allowed 5 misses."),
      (3, "Hard game; you are allowed 3 misses.")
    )
    div(
      p("Inspired from ")(a(href:="http://www.yiiframework.com/demos/hangman/", target:="_blank","Yii's demo")),
      p("This is the game of Hangman. You must guess a word, a letter at a time.\n" +
        "If you make too many mistakes, you lose the game!"),
      form(id := "playForm")(
        for((level,text) <- levels) yield {
          val levelId = s"level_${level}"
          div(`class`:="radio")(
            input(id:=levelId, `type`:="radio", name:="level", onclick:={ ()=>
              Model.level() = level
            }, {if(level == Model.level()) checked:="checked"}),
            label(`for`:=levelId, style:="padding-left: 5px")(text)
          )
        }, br,
        input(`type`:="button", value:="Play!", `class`:="btn btn-primary", onclick:={ () =>
          if(Model.level() > 0) {
            Model.start()
            goto(pageGuess)
          }else{
            dom.alert("Please select level!")
          }
        })
      )
    )
  }

^ 这个 ScalaTag 代码实际上生成的 HTML 可以被没有 javascript 支持的简单网络爬虫读取，还是它生成的 Javascript 正在修改 DOM 生成 div 和段落还有什么不是？

我尝试阅读文档，但是 div 和 p 除了 "Pattern: div: Tags.this.ConcreteHtmlTag[html.Div]"

之外还有 none

Answer 1

它同时使用了两者，至少现在它使用了：

来自文档：

Although Scalatags was originally a HTML-String generation library, it now
ships with an additional backend that runs only on ScalaJS.

此外：

The DOM backend provides an additional method .render on all Scalatags fragments, which converts the fragment into a DOM tree:

val elem = div.render
assert(elem.children.length == 0)
elem.appendChild(p(1, "wtf", "bbq").render)
assert(elem.children.length == 1)
val pElem = elem.children(0).asInstanceOf[Paragraph]
assert(pElem.childNodes.length == 3)
assert(pElem.textContent == "1wtfbbq")
As you can see, you can manipulate DOM elements directly, calling standard DOM APIs like .children, .appendChild, etc.

As you can see, you can manipulate DOM elements directly, calling standard DOM APIs like .children, .appendChild, etc. Which as you know are Javascript!
