如何使用角度JS剑道UI网添加条件列？

Question

我们如何添加一个条件列到kendo ui网格。这样

[{ 
    "ProductID": 1, 
    "ProductName": "Chai", 
    "Supplier": { 
     "SupplierID": 1, 
     "SupplierName": "Exotic Liquids" 
    }, 
    "Category": { 
     "CategoryID": 1, 
     "CategoryName": "Beverages" 
    }, 
    "UnitPrice": 18.0, 
    "UnitsInStock": 39, 
    "Discontinued": false, 
    "layers": [ 
     { 
     "layer_Layer1": { 
      "layerType": "top", 
      "layer": "L1", 
      "groups": [] 
     } 
     } ] 
},{ 
    "ProductID": 2, 
    "ProductName": "Chang", 
    "Supplier": { 
     "SupplierID": 1, 
     "SupplierName": "Exotic Liquids" 
    }, 
    "Category": { 
     "CategoryID": 1, 
     "CategoryName": "Beverages" 
    }, 
    "UnitPrice": 19.0, 
    "UnitsInStock": 17, 
    "Discontinued": false, 
    "layers": [ 
     { 
     "layer_Layer2": { 
      "layerType": "top", 
      "layer": "L2", 
      "groups": [] 
     } 
     } 
    ] 
}]

我有JSON输入columns.fields我给layers[0].layer_Layer1.layer但有时我得到layers[0].layer_Layer2.layer。

我们如何配置此剑道UI？

如果我得到你的权利，你想在一列来显示或者layer_Layer1或layer_Layer2的价值，这取决于哪一个是不是空白。

你可以尝试一个template：

# if (layers && layers[0].layer_Layer1) { # 
    #: layers[0].layer_Layer1.layer # 
# } else if (layers && layers[0].layer_Layer2) { # 
    #: layers[0].layer_Layer2.layer # 
# } #
