Question

如何获取单个实体记录数据请查看下面的代码在xml table.am中进行绑定，如下所示

table in xml view 
<Table  items="{/dum}" id="table" width="auto">

当您可以将网址直接绑定到表格时：

如果我按照以下方式给出所有记录。

 var url = "/myentity";
    var table = oView.byId("table");
    table.bindItems({
        path: url,
        template: table.getBindingInfo("items").template
    });

如果我给var url = "/myentity('srujan')"; 我无法获得特定的用户数据

这是显示它如何适用于您的案例的bindElement（XML中的“绑定”）的代码段：

var oModel = new sap.ui.model.json.JSONModel({
    "Product(1)": {
      Price: 100,
      Name: "Product # 1"
    },
    Products: [{
      Price: 200,
      Name: "Product # 1"
    }, {
      Price: 500,
      Name: "Product # 2"
    }, {
      Price: 542,
      Name: "Product # 3"
    }]
  });

  sap.ui.getCore().setModel(oModel);

  sap.ui.xmlfragment({
    fragmentContent: document.getElementById("table").textContent
  }).placeAt("content");
