您不是根据选择构建参数，而是导航到所需的值。例如，国家/地区---〉州/省----〉城市
您不是在构建CountryStateCity变量，而是在声明City变量是您选择的值。

我可以通过使用扩展选择参数〉JSON参数类型〉JSON参数配置Groovy脚本来获得最接近的结果。

import org.boon.Boon;
def jsonEditorOptions = Boon.fromJson(/{
  disable_edit_json: true,
  disable_properties: true,
  no_additional_properties: true,
  disable_collapse: true,
  disable_array_add: false,
  disable_array_delete: false,
  disable_array_reorder: false,
  theme: "bootstrap3",
  iconlib: "fontawesome5",
  schema: {
   "type": "object",
   "title": "",
   "required": [
    "Locations"
   ],
   "properties": {
    "Locations": {
     "type": "array",
     "format": "table",
     "title": "",
     "uniqueItems": true,
     "items": {
      "type": "object",
      "title": "Location",
      "properties": {
       "Country": {
        "type": "string",
        "propertyOrder" : 1,
        "enum": [
         "USA",
         "Germany",
         "India"
        ]
       },
       "City": {
        "type": "string",
        "propertyOrder" : 2,
        "enum": [
         "New York",
         "Frankfurt",
         "Mumbai"
        ]
       },
       "Neighborhood": {
        "type": "string",
        "propertyOrder" : 3
       }
      }
     },
     "default": [{
      "Country": "USA",
      "City": "New York",
      "Neighborhood": "Times Square"
     }]
    }
   }
  }
  /);

您可以访问plugin page和json-editor.github.io来创建和验证JSON模式，如上所示。
这是如何出现在Jenkins：

但是请注意，它仍然不提供基于第一列中所选内容的上下文相关的第二列。第二列的行为与第一列完全相同，您可以从预定义列表中进行选择，而不使用任何过滤器。
在打印变量Location时，它返回以下JSON：

{"Locations":[{"City":"New York","Country":"USA","Neighborhood":"Times Square"},{"City":"Frankfurt","Country":"Germany","Neighborhood":"Bornheim"},{"City":"Mumbai","Country":"India","Neighborhood":"Vile Parle"}]}

我遇到了同样的问题，所以我在参数文件中添加了一个“行号”列：

Country         City            Row
    United States   San Francisco   1
    United States   Chicago         2
    Mexico          Mexico City     3
    Mexico          Cancun          4

这样，插件返回行号，我可以从参数文件中寻址该行。
