由于HierarchicalDataSource，我试图显示Kendo树视图。 它是一个简单的地区，国家，城市等级，但困难在于我们有3个可能的地区，国家可以出现在第二或第三层。
基本上， - 第一级区域仅包含其他区域 - 第二级地区包含其他地区或国家 - 第三级区域仅包含国家
以下是我的架构：
var portsSchema = {
schema: {
data: "PortList",
model: {
id: "Code"
}
}
};
var countrySchema = {
schema: {
data: "CountryList",
model: {
id: "Code",
children: portsSchema
}
}
};
var regionCountrySchema = {
schema: {
data: "RegionList",
model: {
id: "id",
children: countrySchema
}
}
};
var regionSchema = {
schema: {
data: "RegionList",
model: {
id: "id",
children: regionCountrySchema
}
}
};
根据该地区是否有国家这一事实，我想指定一种特定类型的儿童（regionSchema或regionCountrySchema）。
var tvDataSource = new kendo.data.HierarchicalDataSource({
data: regions,
schema: {
model: function (data) {
**how to return the right children schema ?**
}
}
});
返回{children：regionSchema}或{children：regionCountrySchema}会触发js kendo错误。
有任何想法实现这一目标吗？谢谢。 下面的JSON数据示例。
