Knockout.SimpleGrid 和嵌套对象

Question

我有一个这样的对象：

{
    "ObjectId": 20001,
    "Time": "2008-07-12T23:30:00",
    "NestedObject": {
        "NestedObjectId": 45,
        "ParameterName": "Heart Rate",

    }

}

我的 SimpleGrid 数据映射很简单：

 { headerText: "Object Id", rowText: "ObjectId" },
 { headerText: "NestedObject", rowText: "NestedObject.NestedObjectId" },
 { headerText: "Time", rowText: "Time" }

它不绑定 NestedObject.NestedObjectId。有谁知道我是否必须延长淘汰赛才能获得此功能？还是内置的？

Answer 1

您可以使用 function 作为 rowText 的参数：

{ 
    headerText: "NestedObject", 
    rowText: function (item) { return item.NestedObject.NestedObjectId; } 
}

演示 JSFiddle. (The sample were taken from here: Paged grid)
