So I have this legacy program that has been running forever without any problems (showing a map with custom markers and functionallities), and suddenly this week the webbrowser component stopped working. First I get this script error message:
and when I say "yes" I get the next message:

I have tried modifying registry as explained here, but it does not work.
Am I missing something or it is just that google apis stopped supporting legacy browsers? Is there any workaround? Any help appreciated.

Add &v=3.47 to your script tag to keep the app working until August 2022.

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 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,

I am using webamp to show the map created in ArcGIS (Javascript API in PHP website). In the map, a popup also appears when clicking on the layer's points. Recently I have updated the version 4.14 from 4.13. After updating it, the popup is not working properly. I have a custom popup template. After research in the documentation, I came to know there required a return function to show the custom div on the popup. The below code I have added to show my custom popups.
var template = { content: function(){ var div = document.createElement("div"); div.className = "myClass"; div.innerHTML = "<span>My custom content!</span>"; return div; } }
layers[layerIndex].popupTemplate = template;
Now the popup appears fine. But I have to show the field values on the popup. I have used the required field attributes in double brackets eg: {Name}. But in the latest version, the field values are not appearing when I used the same.
The code I have used in version 4.13 and it was working,
popupTemplate = {
title: "{Name}",
content: '<div id="popup_address">{Address}</div><div class="right"><div href="#" id="popupRight" class="toggle"><p onClick="openPopupDetails({FACILITYID})">+</p></div></div>' };
layers[layerIndex].popupTemplate = popupTemplate;
Please help me to fix this issue.
Thanks.

I have modified the code,
for (let i = 2; i < layers.length; i++) {
var template = {
title: "{Name}",
content: function() {
var div = document.createElement("div");
div.innerHTML =
'<div id="popup_address">{Address}</div><div class="right"><div href="#" id="popupRight" class="toggle"><p onClick="openPopupDetails({FACILITYID})">+</p></div></div>';
return div;
}
};
layers[i].popupTemplate = template;
console.log(layer[i]);
}
When I apply custom div, the {Address} part is not rendering. It appears like {Address} itself.
I think you are a bit confuse, you still can use a string, or you can use a function for the content of the popup template. So if you want to use a function, you can use something like this,
popupTemplate = {
title: "{Name}",
content: popupContentChange
}
layers[layerIndex].popupTemplate = template;
function popupContentChange(feature) {
let div = document.createElement("div");
div.className = "myClass";
div.innerHTML = "<span>"+feature.graphic.attributes.Address+"</span>";
return div;
}
There are several examples in the API documentation, take a look there. Just to reference one, ArcGIS JavaScript API Examples - Intro to Popups
Here an example I made for you taking your code as base adding some fixes to display what you want.

If you want to use a function as content, you have to set the outFields parameter to include the fields you want to use in the function. The selected feature is pass as a parameter to the function, and inside you use feature.graphic.attributes to access the attributes. This should work,
var template = {
title: "{Name}",
// content: "<span>Address: {Address}</span>"
content: function(feature) {
console.log(feature);
var div = document.createElement("div");
div.className = "myClass";
div.innerHTML = "<span>Address:"+feature.graphic.attributes.Address+"</span>";
return div;
},
outFields: ["Name", "Address"]
};
featureNavigationEnabled is deprecated as of version 4.15. Use Popup.visibleElements.featureNavigation instead.

I have the following code of a map using api google, I have tested the code in several html editor and its work perfectly, but when i upload in my web page doesn’t work. The map appears all zoomed in some random point in the ocean. I create an article in Joomla 1.5.20, paste the code. Its shows right in the preview but not in the web page. I disable filtering and use none editor and still won’t work. Thanks for the help.
