Javascript 4.x zoomEnd Event / Scale Text

DavidPlume1

I'm trying to generate scale text (e.g. 1/100,000 ) in the JS 4.5 API. I can find MapView.scale but have not been able to locate anything like a "zoomEnd" event.

In 4.x API -- where might I find and event at the end zooming in our out please?

Thanks

David

David,

In 4.x you need to dismiss the old ideas of having events for everything and you need to get use to watching properties.

view<SPAN class="punctuation token">.</SPAN><SPAN class="token function">watch</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="string token">'extent'</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="keyword token">function</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">{</SPAN>
&nbsp; <SPAN class="comment token">//do something because the extent has changed. </SPAN>
<SPAN class="punctuation token">}</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN>‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Leo,

You can watch the stationary property.

Hi @Robert,

When I watch the extent property, there will be lots of triggers when zoom the map only once.

My question is:

How to determine the zoom event is end?

Thanks,

Leo
