javascript - 使用anyOf查看对象名称？

Question

我在这里有一个模式，我想在其中有一个下拉列表，选择一个选项，然后从那里 - 根据选择出现不同的选项；所有内容都嵌套在一个数组中以具有多个它们。

我注意到，当我填写虚拟数据时，输出 json 并未存储所选选项的名称

所以 data.json 看起来像这样:

{
  "page1": [
    {
      "imageOptions": {
        "imageHeightType": "vh",
        "imageHeight": 50
      },
      "textboxArea": {
        "headerText": "Header for selection1",
        "headingTag": "h1",
        "textBoxOpacity": 15
      }
    },
    {
      "content": "This is a complety different selection, yet there is no name to tell the difference between these two difference objects"
    }
  ]
}

正如您所看到的，没有对象可以将这两个不同的项目包装在 page1 数组中 - 理想情况下需要类似的东西:

{
  "page1": [
    {
     // Title of object goes here from schema
      "imageOptions": {
        "imageHeightType": "vh",
        "imageHeight": 50
      },
      "textboxArea": {
        "headerText": "Header for selection1",
        "headingTag": "h1",
        "textBoxOpacity": 15
      }
    },
    {
      // Title of object goes here from schema
      "content": "This is a completely different selection, yet there is no name to tell the difference between these two difference objects"
    }
  ]
}

有办法做到这一点吗？我已经查看了 AnyOf 的文档，但运气不佳。对于 React-JsonSchema-Forms 来说相当新。

以下是我当前的架构:

{
  "type": "object",
  "properties": {
    "page1": {
      "type": "array",
      "items": {
        "type": "object",
        "anyOf": [
          {
            "title": "Full Width Image",
            "type": "object",
            "properties": {
              "imageOptions": {
                "type": "object",
                "title": "Image",
                "properties": {
                  "image": {
                    "type": "string",
                    "title": "Image",
                    "format": "data-url"
                  },
                  "imageHeightType": {
                    "enum": [
                      "px",
                      "vh"
                    ]
                  },
                  "imageHeight": {
                    "type": "number",
                    "title": "Image Height"
                  }
                }
              },
              "textboxArea": {
                "type": "object",
                "title": "Textbox Area",

                  },
                  "headingTag": {

                      "h3"
                    ]
                  },
                  "imageText": {
                    "type": "string",

                  },
                  "textboxPosition": {
                    "title": "Textbox Position",
                    "enum": [
                      "Left",
                      "Center",
                      "Right"
                    ]
                  },
                  "textboxColor": {
                    "title": "Color of Textbox Area",
                    "type": "string"
                  },
                  "textBoxOpacity": {
                    "title": "Textbox Opacity %",
                    "type": "integer",

为什么不直接为每个对象添加一个类似名称的属性呢？如果需要，您可以隐藏/禁用它:

架构:

"anyOf": [
    {
        "title": "Full Width Image",
        "type": "object",
        "properties": {
            "name": {
                "type": "string",
                "default": "fullWidthImage"
            },
            "imageOptions": {
                "type": "object",
                "title": "Image",
                "properties": {...}
                ...
            }
            ...
        }
    },
    {
        "title": "Custom Block",
        "type": "object",
        "properties": {
            "name": {
                "type": "string",
                "default": "custom"
            },
            "content": {
                "type": "string"
            }
        }
    }
]

用户界面架构:

{
    "page1": {
    "items": {
        "name": {
            "ui:widget": "hidden"
        },
        "imageOptions": {...},
        ...
    }
}

formData 应该如下所示:

{
    "page1": [
        {
            "name": "fullWidthImage",
            "imageOptions": {
                "imageHeightType": "vh",
                "imageHeight": 50
            },
            "textboxArea": {
                "headerText": "Header for selection1",
                "headingTag": "h1",
                "textBoxOpacity": 15
            }
        },
        {
            "name": "custom",
            "content": "This is a complety different selection, yet there is no name to tell the difference between these two difference objects"
        }
    ]
}
