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

Question

我想在Play框架视图中将Scala值传递给JavaScript JSON

当我检查以下代码时，在JSON数据的第1列第10行得到"SyntaxError: JSON.parse: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>

谁来帮帮我

因此，正如您想要的那样，Json为什么不使用Json.obj()。接下来就是你的结构了。

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"
      )
    )
