回答1:

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)-

  1. create a map
  2. add a published layer(arcgis layer url) on the map
  3. show popup on the click of published gis layer.

As your example says you don't have a webmap id so you not need to worry about that.

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/esri/css/esri.css">
    <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>

Note- Update the sample code as per comments in it.

If you want more info let me know i will update the answer accordingly.

Hoping this will help you :)

Well, you apparently adapted this sample: https://developers.arcgis.com/javascript/3/jssamples/ags_createwebmapid.html I am not sure if this is what you want, as using webmaps needs some licensing, I guess. In any case, you need to change few lines in your example. Instead of

<link rel="stylesheet" href="css/layout.css">

you should have

<link rel="stylesheet" href="https://developers.arcgis.com/javascript/3/samples/ags_createwebmapid/css/layout.css">

to load the original CSS file. You should make your own copy and load it from your server. More important is to change this line:

arcgisUtils.arcgisUrl = "http://localhost:6080/arcgis/rest/services/Soil_Maps/changa_manga_soil_map/MapServer/0";

which should be:

arcgisUtils.arcgisUrl = "https://www.arcgis.com/sharing/rest/content/items/";

or, as the sample suggests, path with YOUR portal URL. And, last but not least, the next line must be something like:

arcgisUtils.createMap("ef9c7fbda731474d98647bebb4b33c20","map").then(
