【问题描述】：

我有一个 JSON 对象如下：

{
"Routes": 
{
"A":
[
{"Locality": "L1","Pickup": "Junction1","Time": "6:45AM"},
{"Locality": "L2","Pickup": "Junction2","Time": "6:48Am"},
{"Locality": "L3","Pickup": "Junction3","Time": "6:50AM"},
{"Locality": "L4","Pickup": "Junction4","Time": "6:55AM"},
{"Locality": "L5","Pickup": "Junction5","Time": "6:58AM"},
{"Locality": "L6","Pickup": "Junction6","Time": "7:00AM"}
]
,

"A1":
[
{"Locality": "K1","Pickup": "Junction1","Time": "6:45AM"},
{"Locality": "K2","Pickup": "Junction2","Time": "6:48Am"},
{"Locality": "K3","Pickup": "Junction3","Time": "6:50AM"},
{"Locality": "K4","Pickup": "Junction4","Time": "6:55AM"},
{"Locality": "K5","Pickup": "Junction5","Time": "6:58AM"},
{"Locality": "K6","Pickup": "Junction6","Time": "7:00AM"}
]
}
}

并在控制器初始化函数中将模型设置为 UI5 视图，如下所示。

var oModel1 = new sap.ui.model.json.JSONModel("model/routes.json");
this.getView().setModel(oModel1,"tablemodel");

JSON 模型存储在如上所示的模型文件夹中。

在视图中我已经声明了一个表。

如何将 JSON 文件中存在的所有“A1”路由绑定到表中。我很困惑给出表的路径来绑定行。

【解决方案1】：

var oModel = new sap.ui.model.json.JSONModel("model/routes.json");
oTable.setModel(oModel);
oTable.bindRows("/Routes/A1");

&lt;iframe width="100%" height="300" src="//jsfiddle.net/6qbe2Lgs/1/embedded/" allowfullscreen="allowfullscreen" frameborder="0"&gt;&lt;/iframe&gt;

【讨论】：

我们可以使用设置为表视图（oTable）的模型而不将模型显式设置为表吗？
是的，它可以工作，但它不适用于命名模型，所以在这种情况下，对于绑定到视图的命名模型，是否必须将模型绑定到表？
对于命名模型，您需要将绑定路径更改为：“tablemodel>/Routes/A1”.. 对于属性也将是“{tablemodel>Locality}”
您能否详细说明我无法使用命名模型获得结果。那是视图的绑定模型并将表的属性绑定到视图的命名模型？
