time-extent-change TimeSlider Event in 4x

MichaelWen_Timmons — Wed, 20 Jul 2022 21:50:56 GMT

I have an app written in JS API 3x that made extensive use of the 'time-extent-change' event to handle a lot of UI and background changes. I noticed that it is no longer available in JS API 4x.

Is there a way to get an event to fire whenever a user moved the slider manually, or used the Play button in 4x?

You can watch the "timeExtent" property on TimeSlider, like this:

timeSlider.watch("timeExtent", (newVal, oldVal) =>{ // do something with the old and new values console.log("Old timeExtent: ", oldVal); console.log("New timeExtent: ", newVal); });
