ArcGIS- WebMapCreation Error - dojo

I have created a exact sample example and when trying to run it . I am getting lots of errors. Can someone show me how to fix this?
https://developers.arcgis.com/javascript/jssamples/gp_popuplink.html
here is one of the Error:
NS_ERROR_DOM_BAD_URI: Access to restricted URI denied { response={...}, xhr=XMLHttpRequest, code=1012, mor
I am also including the entire working code below:

You're missing an essential part of configuration. As can be seen in the error you're getting, your esrimap is fetching a bad url. That's because you haven't setup your server as can be seen in the example you're referring to:
//This service is for development and testing purposes only. We recommend that you create your own geometry service for use within your applications.
config.defaults.geometryService = new GeometryService("http://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/Geometry/GeometryServer");
Here's a simple stripped down example on Plunker.
var map;
require([
"esri/map",
"esri/arcgis/utils",
"esri/tasks/GeometryService",
"esri/config",
], function(
Map,
arcgisUtils,
GeometryService,
config
) {
config.defaults.geometryService = new GeometryService("http://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/Geometry/GeometryServer");
config.defaults.io.proxyUrl = "/proxy/";
arcgisUtils.createMap("a193c5459e6e4fd99ebf09d893d65cf0", "mapDiv").then(function(response){
window.map = response.map;
});

Geocoding Openstreetmap gives different responses depending on zoom-level

I am trying to figure out why when hoovering on a village when zoom level is low show's the town of Västerås instead of Irsta, but when I zoom in it shows the village of Irsta.
You guys can try it yourselves in this example.
I would like to be able to locate Irsta when you can see the label of Irsta, it shouldn't be the bigger city of Västerås in that case.

Zoom-in picture of village Irsta
Normal zooom of village Irsta
This is happening as you are using a dynamic zoom level in your reverse Nominatim request. If the zoom level is lower than 14, Nominatim will try to get the next city, (or if it way lower, even the country, etc., see https://nominatim.org/release-docs/develop/api/Reverse/#result-limitation )
So you'll have to define a min-value in your zoom while doing the reverse call, e.g. q&d:
reverseZoom=Math.max(14,map.getZoom());
fetch(`https://nominatim.openstreetmap.org/reverse.php?lat=${e.latlng.lat}&lon=${e.latlng.lng}&zoom=${reverseZoom}&format=json`)
Now the reverse call will always try to get a village, but - and this may be a problem - also a suburb instead of a city (but this would have happened with your original code as well if you zoom in). So I would recommend to use addressdetails=1 in your request and parse the addressdetails response for city/village/town to return that value instead of the display name value.

Change search result marker icon to a custom

I have the following code that is currently working. I have been looking all over and cannot find how to change the icon way from the tiny dot that defaults on the location. The code below is set to a specific address on page load.
I have tried PictureMarkerSymbol as you'll see I have that loaded into the function, but I'm not getting the right logic.
I figured this would be the easy part of using arcgis, but it's proving to be difficult.
thanks!

It looks as the search widget resultGraphic is readonly, but it looks like you can specify a collection of SearchSource and provide it a symbol. You can almost use the default setting provided in an example under sources in documentation. Below is an example. You can use this tool for creating symbols.

Esri Arc Online using API to see filter result into a simple web page

I need to create a simple webpage where I can see the result of filters in arc online into it instead of creating the filter each day. By that, the results will be refreshed automatically each day when I log in into arc gis.
I heard that there is an API, is my idea is feasible ?
Assuming you want to filter a FeatureLayer--the original question is unclear, but FeatureLayer seems logical--you should set the definitionExpression property, as described in the FeatureLayer documentation.
Here's an example:

var featureLayer = new FeatureLayer({

definitionExpression: "Sci_Name = 'Ulmus pumila'"

map.add(featureLayer);
view.then(function() {
on(dom.byId("filterInput"), "change", updateFilter);
function updateFilter(ev) {
featureLayer.definitionExpression = ev.target.checked ?

undefined;

How to display wfs layer using arcgis api javascript

I am new to ArcGIS API Javascript and I have this task given to edit the feature layer atrribute through WFS layer.Problem is I don't know how to display map using WFS layer.Please help!
You need to use WFSLayer to add WFS service to map. Below is a sample provided by ESRI. Take a look at it.
<!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>
UPDATE: updated with different wfs service which works.

dojo.require statement is not loading esri Map module as expected

I am working on a php application where I used 'arcgis' API for loading a map. please find the URL below:
http://js.arcgis.com/3.11/
In order to load an arcgis map in my application, I must use
dojo.require("esri.map");
So In my single page PHP application I added this require statement as below:
<script type="text/javascript">
dojo.require("esri.map");
</script>
And in a js file I gave the map is loaded as shown below:
var myOptions = {
maxZoom: 20,
minZoom: 3,
zoom:5,
isZoomSlider: false,
sliderStyle: "large",
sliderPosition: "top-right"
};
this.map = new esri.Map("mapDiv", myOptions);
But when I run this application, I am getting an error stated "Uncaught TypeError: undefined is not a function" at the line "this.map = new esri.Map("mapDiv", myOptions);"
If I open developer tools run the same code by keeping breakpoints at require and esri.Map statements, I could see the map is getting loaded. But If I run it without opening developer tools then I am facing this issue.
Why dojo.require statement is not working as expected?
Whats wrong am I doing??
Kindly reply
You are trying to load map module with legacy module require. Try require Map using AMD syntax as shown in docs:
require(["esri/map"], function(Map) { /* code goes here */ });
You need to wrap your JavaScript code in a call to dojo.ready.
