JavaScript ArcGIS FeatureLayer.url用法及代码示例

基本信息

以下是所在类或对象的基本信息。

AMD: require(["esri/layers/FeatureLayer"], (FeatureLayer) => { /* code goes here */ });

ESM: import FeatureLayer from "@arcgis/core/layers/FeatureLayer";

类： esri/layers/FeatureLayer

继承: FeatureLayer > Layer > Accessor

自从：用于 JavaScript 4.0 的 ArcGIS API

用法说明

FeatureLayer.url函数(或属性)的定义如下：

url String

图层、非空间表或服务的 REST 端点的绝对 URL。 URL 可能指向ArcGIS Enterprise 或ArcGIS Online 上的资源。

如果 url 直接指向服务，则必须在 layerId 属性中指定图层。如果没有给出layerId，那么将加载服务中的第一层。

例子：

// Hosted Feature Service on ArcGIS Online
layer.url = "http://services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/origins/FeatureServer/0";

// Layer from Map Service on ArcGIS Server
layer.url = "http://sampleserver6.arcgisonline.com/arcgis/rest/services/Census/MapServer/2";

// Can also be used if URL points to service and not layer
const layer = new FeatureLayer({
  // Notice that the url doesn't end with /2
  url: "http://services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/MonterreyBayCanyon_WFL/FeatureServer",
  layerId: 2
});

// Non-spatial table in San Francisco incidents service.
const table = new FeatureLayer({
  url: "https://sampleserver6.arcgisonline.com/arcgis/rest/services/SF311/FeatureServer/1"
});
// table must be loaded so it can be used in the app.
table.load().then(function() {
  // table is loaded. ready to be queried.
});
