Friends,

Maybe you can use event:

{
  "type": "page",
  "body": {
    "type": "form",
    "body": [
      {
        "label": "选项",
        "type": "select",
        "name": "select",
        "menuTpl": "<div>${label} 值：${value}, 当前是否选中: ${checked}</div>",
        "options": [
          {
            "label": "A",
            "value": "a"
          },
          {
            "label": "B",
            "value": "b"
          },
          {
            "label": "C",
            "value": "c"
          }
        ],
        "onEvent": {
          "change": {
            "actions": [
              {
                "actionType": "dialog"
              }
            ]
          }
        }
      }
    ]
  }
}
