我正在尝试为屏幕上的控件构建一个json架构。我将控件（controltype）限制为枚举，并为所有控件添加了所有可能的属性。 问题是并非所有属性都与所有控件相关。 在我的例子中：＆＃34;选项＆＃34;财产与＆＃34; SectionTitle＆＃34;无关。控制类型，但它与＆＃34; Dropdown＆＃34;。
相关{
"controls": {
"type": "array",
"$id": "/properties/data/properties/metadata/properties/page/properties/controls",
"properties": {
"controlType": {
"type": "string",
"enum": ["SectionTitle",
"Dropdown",
"CustomButton"],

oneOf或anyOf 如果您的属性的可接受值数量有限（例如枚举），但是每个可能的值都需要单独映射，则此功能很有用。
