服務中要包含在每個函數中的字段名稱數組。要從圖層中的所有字段獲取值,請使用
["*"]
。outFields
中指定的字段將與渲染、標記和設置圖層的高程信息所需的字段一起請求。必填字段和outFields
用於填充 FeatureLayerView.availableFields 。如果字段不是用於渲染的必需字段的一部分,則設置此屬性以包括將用於客戶端 queries 的字段。默認值:null
例子:
// Includes all fields from the service in the layer fl.outFields = ["*"];
// Get the specified fields from the service in the layer // These fields will be added to FeatureLayerView.availableFields // along with rendering and labeling fields. Use these fields // for client-side filtering and querying. fl.outFields = ["NAME", "POP_2010", "FIPS", "AREA"];
// set the outFields for the layer coming from webmap webmap.when(function () { layer = webmap.layers.getItemAt(1); layer.outFields = ["*"]; });
