使用经典ASP的ASPJSON解析JSON时遇到问题

我正在使用ASP JSON

我试图解析下面这个JSON响应的历史记录。我可以像这样获得property对象下的所有节点

oJSON.数据（“财产”）.项目（0）.项目（“年份”）.项目（“上次修改”）

然而，当我尝试更深入时，我会出错

我试过了

但是它不返回任何内容

我认为这与属性是一个对象和SalesHistory是属性内部的一个对象这一事实有关，但是我似乎无法从SalesHistory级别获取值

下面是我试图解析的JSON结构。任何帮助都将不胜感激

事实上，我能把它弄明白

因为它是属性对象中的嵌套对象，所以我需要执行以下操作才能访问它

回复。填写oJSON。数据（“财产”）。项目（0）。项目（“销售历史”）。项目（0）。项目（“金额”）。项目（“销售金额”

添加.item（0）售后历史记录允许我访问salehistory对象
