angularjs - 国家 -> 州 -> 城市与角度模式形式动态选择

Question

我目前正在使用 angular-schema-form-dynamic-select，我的要求是根据所选国家/地区选择州。我将数据存储在数据库中，例如 this country -> state -> city。谁可以帮我这个事？

这是我的表格：

[
  {
    "key": "country",
    "type": "strapselect",
    "placeholder":"country",
    "options": {
      "httpGet": {
        "url": "/countries" 
      },
      "map": { "valueProperty": "readonlyProperties.id", "nameProperty":"name" }
    }
  },
  {
    "key": "state",
    "type": "strapselect",
    "placeholder":"state",
    "options": {            
      "httpGet": {
        "url": "/states"         
      },
      "map": { "valueProperty": "readonlyProperties.id", "nameProperty":"name" }
    }
  },
  {
    "key": "city",
    "type": "strapselect",
    "placeholder":"city",
    "options": {
      "httpGet": {
        "url": "/cities"
      },
      "map": { "valueProperty": "readonlyProperties.id", "nameProperty":"name" }
    }
  }
]

Answer 1

我认为这样的功能确实非常方便。也许你在 json 字符串中写了这样的东西：

{
    "type": "object",
    "properties": {
        "country": {
            "type": "string",
            "enumCallback": "getTitlesValues()"
        }
    }
}

在您的控制器中，您将定义该回调：

...
$scope.getTitlesValues = function () {
    return ['India','Australia', 'Germany', 'Sweden']
}
...
