如何将数据从 scala 发送到 Html 页面中的特定 div 标签

Question

I have a List[List[String]] in my Scala side which I have to send to a div tag of a particular HTML page.

    <div class="pagecolumn" style="background-color: #FFFFFF;">
         <button class="collapsible">Data Info</button>

        <div id="resultDiv" >
          
        </div>
    </div>
   
     
def getResultantValues(modelObject: String, keyName: String):Unit = {
var result = modelObject.replaceAll("\\[","").split("]")
var resultList : mutable.MutableList[mutable.MutableList[String]]= null
for (i<-0 until result.length) {
  resultList += result(i).split(",")
}}`

I have to send ResultList to the resultDiv .

Without providing details it's quite hard to understand exactly why you need to process the modelObject like that or what is the point of keyName in your code, but assuming you have ResultList of type List[List[String]] , and you just need a way to send resultList to resultDiv , here's how you can do that in Scala:

object Something extends App {

  def getResultantValues(modelObject: String): String = {
    val rawSentences: List[String] =
      modelObject
        .replaceAll("makes no sense", "is nonsense")
        .split("\\.")
        .toList
    val resultList: List[List[String]] =
      for (word <- rawSentences) yield word.strip.split(",").toList
    resultList.flatten.mkString("\"", ".", "\"")
  }

  val resultDiv = getResultantValues(
    "This sentence makes no sense. This sentence makes no sense too."
  )

  val htmlString =
    s"""
       |<div class="pagecolumn" style="background-color: #FFFFFF;">
       |    <button class="collapsible">Data Info</button>
       |
       |    <div id=$resultDiv >
       |          
       |    </div>
       |</div>
       |""".stripMargin

  println(htmlString)
}

Outputs:

<div class="pagecolumn" style="background-color: #FFFFFF;">
    <button class="collapsible">Data Info</button>

    <div id="This sentence is nonsense.This sentence is nonsense too" >
          
    </div>
</div>
