Event listener on popup open?

LarsFagerbakke — Wed, 20 Dec 2017 10:33:34 GMT

Is there a way to add an event on a popup open event? I want, based on its target, to perform a AJAX call and retrieve more data to populate the content field from a third party system.

Popup only has the "trigger-action" event that handles action within the popup.

Lars,

There are actually very few events in the 4.x api. You now just watch properties.

https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-Popup.html#visible

Use view.popup.watch("visible", function(){});

Thank you Robert, this is what I was looking for.

I was getting doubled results when the pop up was turned on and off, so I added an if statement

view.popup.watch("visible", function (popUpStatusChange) {
if (popUpStatusChange == true) {
console.log("Pop-up watch has been fired")
console.log("Pop-up title is:", view.popup.title); //returns the pop up title
console.log("Pop-up content is:", view.popup.content); //returns the pop up content
}
});
