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,
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 usefeature.graphic.attributes
to access the attributes. This should work,featureNavigationEnabled
is deprecated as of version 4.15. UsePopup.visibleElements.featureNavigation
instead.https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-Popup.html#featureNavigationEnabled
