General question: Using API-documentation and EXPAND-Widget

KaiBehncke — Tue, 20 Aug 2024 13:16:21 GMT

Dear users,

I`m still on my way to learn "ArcGIS Maps SDK JS".

I have successfully created an Expand-widget like:

const expandbutton = new Expand({ view: view, content: "<br><b>Legende</b><br>", label: "Legende", id: "legendendings", expandTooltip:"Legende", expanded:false, container: document.createElement("div") }); view.ui.add(expandbutton, "bottom-right");

In the API-documentation (https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-Expand.html) I find the "on"-function.

I would like to test it like:

expandbutton.on("click", function(event){ alert ("hello"); });

...but if I lick on the expandbutton no "hello" appears. Do I misunderstand someting?

The "click" event is not available in the expand widget. Instead, I would recommend watching the "expanded" property, as shown in the code snippet below.

expandbutton.watch("expanded", (value)=>{ console.log(`expanded: ${value}`); })
