javascript - 如何将 Scala Map[String,Map[String,String]] 传递给 Js 对象

Question

我想在 Play 框架 View 中将 Scala Map 值传递给 JavaScript JSON onject

当我检查以下代码时，出现“SyntaxError: JSON.parse: JSON 数据第 1 行第 10 列出现意外字符”

val mapTobePassToJs = Map(

      "cg1" -> Map(
        "path" -> "/var/logs/cdr1/cdr",
        "name"  -> "CG-1"

      ),

      "cg2" -> Map(
        "path" -> "/var/logs/cdr2/cdr",
        "name"  -> "CG-2"
      ),

      "cg3" -> Map(
        "path" -> "/var/logs/cdr3/cdr",
        "name"  -> "CG-3"
      ),

      "cg4" -> Map(
        "path" -> "/var/logs/cdr3/cdr",
        "name"  -> "CG-4"
      )
    )

<script type="text/javascript">

        var aChartList = jQuery.parseJSON("@JSONObject(mapTobePassToJs).toString()".replace(/&quot;/g,'"'));

</script>

谁能帮帮我

既然你想要 Json，为什么你不使用 Json.obj()。以下是您的结构。

val mapTobePassToJs = Json.obj(

      "cg1" -> Json.obj(
        "path" -> "/var/logs/cdr1/cdr",
        "name"  -> "CG-1"

      ),

      "cg2" -> Json.obj(
        "path" -> "/var/logs/cdr2/cdr",
        "name"  -> "CG-2"
      ),

      "cg3" -> Json.obj(
        "path" -> "/var/logs/cdr3/cdr",
        "name"  -> "CG-3"
      ),

      "cg4" -> Json.obj(
        "path" -> "/var/logs/cdr3/cdr",
        "name"  -> "CG-4"
      )
    )
