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 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 am new to Arcgis maps and using ArcGIS Javascript 4.2 library. Currently the features are showing up on the map and I am trying to go to feature and open it's popup programmatically. below is my code to query the features which is working fine.
var query = layer.createQuery();
query.where = "key= " + dataItem.key+ "";
query.returnGeometry = true;
query.returnCentroid = true;
query.returnQueryGeometry = true;
layer.queryFeatures(query).then(function (results) {
//I am getting the feature results here.
//trying to navigate to feature and open popup
});
Note: I tried using the following code from documentation which is working fine but I don't have the center as the features are polylines in my case.
view.goTo({center: [-126, 49]})
First, View goTo method has several options, including just using a geometry wich I think would be a better option for your case, zoom to a polyline.
Second to open the popup you just need to use the open method and you can pass there the features to show.
Check this example I put for you, has both suggestions,

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.

I have to change the default icon on the Locate widget on arcGIS 4.18. The default icon class is, esri-icon-locate how can I change it to the class, 'esri-icon-navigation'?
I am going through the documentation,
https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-Locate.html#iconClass
I have tried to use the property, 'iconClass'. But not reflecting in the map icon. Please find the code below,
var locateBtn = new Locate({
view: view,
// iconClass: '\ue666'
iconClass: 'esri-icon-navigation'
});
view.ui.add(locateBtn, {
position: "manual",
});
KER,
You actually right, does not work as expected. Setting iconClass should be the solution.
Funny fact if you check the default iconClass is actually esri-icon-north-navigation, which obviously in not.
Anyway, I am gonna give a dirty solution, just overlap the class you want,
view.when(_ => {
const n = document.getElementsByClassName("esri-icon-locate");
if (n && n.length === 1) {
n[0].classList += " esri-icon-navigation"
}
});

We use Vue.js and OpenLayers (4.6.5) in our web project. We have a lot of features on the map and some of them are polygons. When I select some particular polygon, its style turns to another color, which means it's highlighted (selected). Of course, I can get the coordinates of selected polygon. But, how can I get the coordinates of point inside that polygon where I clicked?
The code look as following:
markObject (mark) {
if (!mark) {
this.map.un('select', this.onMarkObject)
if (this.markSelection) {
this.markSelection.getFeatures().remove(this.lastSelectedFeature)
this.map.removeInteraction(this.markSelection)
}
return
}
if (!this.markSelection) {
this.markSelection = new Select({
condition: condition.click,
layers: [this.vectorLayer]
})
this.markSelection.on('select', this.onMarkObject)
}
this.map.addInteraction(this.markSelection)
},
onMarkObject (event) {
if (event.selected && event.selected.length > 0) {
const coordinates = event.selected[0].getGeometry().getCoordinates()
}
}
Actually, I've found the solution:
onMarkObject (event) {
const clickCoordinates = event.mapBrowserEvent.coordinate
...
}
Thank you anyway.
What you need is to capture the click event on the map, and then transform pixel to map coordinates, take a look at this example I made for you,
