推荐答案
好吧，正如我所看到的，您在下面添加的问题和代码是您要实现的事情(如果我错了，请纠正我)-
well, as i can see the question and code you added above below are this things you want to achieve (correct me if i am wrong)-
- 创建地图
- 添加已发布的图层( arcgis图层网址)在地图上
- 在已发布的gis层的单击上显示弹出窗口.
- create a map
- add a published layer(arcgis layer url) on the map
- show popup on the click of published gis layer.
如您的示例所述，您没有网络地图ID，因此您不必为此担心.
As your example says you don't have a webmap id so you not need to worry about that.
以下是该示例的工作示例-
Below is the working example for that-
require([
"dojo/dom",
"dojo/dom-construct",
"esri/map",
"esri/dijit/InfoWindow",
"esri/layers/FeatureLayer",
"esri/InfoTemplate",
"dojo/string",
"dojo/domReady!"
], function(
dom,
domConstruct,
Map,
InfoWindow,
FeatureLayer,
InfoTemplate,
string
) {
var infoWindow = new InfoWindow({}, domConstruct.create("div"));
infoWindow.startup();
// **** update center according to your feature layer url
var map = new Map("mapDiv", {
center: [-122.41, 37.78],
zoom: 17,
basemap: "topo",
infoWindow: infoWindow
});
var template = new InfoTemplate();
//*** update the title field name according to your feature layer url
template.setTitle("<b>${qAddress}</b>");
template.setContent("${*}");
// ****** replace with your Feature layer url "http://localhost:6080/arcgis/rest/services/Soil_Maps/changa_manga_soil_map/MapServer/0"
var featureLayer = new FeatureLayer("https://services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/Street_Trees/FeatureServer/0",{
infoTemplate: template,
outFields: ["*"]
});
map.addLayer(featureLayer);
map.infoWindow.resize(180, 175);
});
html, body {
height: 100%;
width: 100%;
margin: 0;
padding: 0;
}
body {
background-color:#fff;
overflow:hidden;
}
#header{
border:solid 2px #AAc4c4;
background:#fff;
color:#749749;
border-radius: 4px;
font-size:14px;
padding-left:20px;
font-weight:700;
}
#map{
padding:1px;
border:solid 2px #AAc4c4;
border-radius: 4px;
}

<link rel="stylesheet" href="https://js.arcgis.com/3.20/dijit/themes/claro/claro.css">
<script>var dojoConfig = {
parseOnLoad: true
};
</script>
<script src="https://js.arcgis.com/3.20/"></script>
<body>
<div id="mapDiv"></div>
</body>
注意-根据其中的注释更新示例代码.
Note- Update the sample code as per comments in it.
