Question

我是ArcGIS API Javascript的新手，我有通过WFS图层编辑特征图层的任务。问题是我不知道如何使用WFS图层显示地图。请帮忙！

Answer 1

您需要使用WFSLayer将WFS服务添加到地图中。以下是ESRI提供的示例。看看吧。

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"/>
<title>WFS Layer</title>
<link rel="stylesheet" href="https://js.arcgis.com/3.18/esri/css/esri.css">
<style>
  html, body, #map {
    height: 100%;
    width: 100%;
    margin: 0;
    padding: 0;
  }
</style>
<script src="https://js.arcgis.com/3.18/"></script>
<script>
  var map;

  require(["esri/map", "esri/InfoTemplate","esri/layers/WFSLayer", "esri/config", "dojo/domReady!"], function(Map, InfoTemplate, WFSLayer, esriConfig) {
    map = new Map("map", {
      basemap: "topo",
      center: [-121.936, 37.346],
      zoom: 10
    });

    var layer = new WFSLayer(); 
    
    var opts = {
        "url": "http://www.hcpmaps.com:8080/geoserver/HCP/wfs",
        "version": "1.1.0",
        "name": "citylimits",
        "wkid": 3857,
        "maxFeatures": 100
    };

    esriConfig.defaults.io.proxyUrl = "/sproxy/";

    layer.fromJson(opts);
    
    map.addLayer(layer);

  });
</script>
</head>

<body>
  <div id="map"></div>
</body>
</html>

更新：使用不同的wfs服务进行更新。
