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.

I am using a map with feature layers from ArcGIS and the popup to see some data when the user click on a symbol (feature). Is there a way to style the popups exactly the way we want ? In other words, how could I get the data out of the popup, not display the popup but open a modal with that data instead ? Is that even possible ?
This are actually two questions, can you style the popup?, and can you use your own "popup"?.
For the first one, I would say it is pretty customizable, but obviously it depends what you need.
For the second, you just need to stop the default behavior of the view popup, that is to open on right click, and then catch the event yourself to do what you want. Here is an example I made for you that shows that,

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.

Currently working on showing a popup in the map using ESRI ArcGIS API for JavaScript 4.15.
But that is missing the Maximize button which was available with ArcGIS API for JavaScript 3.35
Is there any config to be set to show the same.
As far as I know the new API does not have that capability out of the box. But no worries, you can implement it by adding a custom action to the popup.
See the example I made for you to get an idea.

To run the snippet, copy and save as an html file. The full screen action does not work in the snippet, I guess because it is embedded, not sure though.
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.

map.addLayer(layer);

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;
});
});
