Directions Widget: Prevent zoom to full route after the route is calculated

MaxMcCosham

Hello,

I'm using the Directions widget in version 3.20 of the API:

Directions | API Reference | ArcGIS API for JavaScript 3.20 

Is it possible to prevent the zoomToFullRoute() method from being called after the route is calculated? I would like to keep the map at its current extent instead of automatically zooming in/out to the calculated route.

Thanks,

Max,

try overriding the Directions class like this:

<SPAN class="keyword token">var</SPAN> NoZoomDirections <SPAN class="operator token">=</SPAN> <SPAN class="token function">declare</SPAN><SPAN class="punctuation token">(</SPAN>Directions<SPAN class="punctuation token">,</SPAN> <SPAN class="punctuation token">{</SPAN>
&nbsp;&nbsp;&nbsp; zoomToFullRoute<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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; console<SPAN class="punctuation token">.</SPAN><SPAN class="token function">log</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="string token">"overriding zoomToFullRoute"</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN>
&nbsp;&nbsp;&nbsp; <SPAN class="punctuation token">}</SPAN>
<SPAN class="punctuation token">}</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN>

<SPAN class="keyword token">var</SPAN> directionsWidget <SPAN class="operator token">=</SPAN> <SPAN class="keyword token">new</SPAN> <SPAN class="token class-name">NoZoomDirections</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="comment token">/*... the usual instantiation */</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Works for me. I only get the console message, not the zoom.

If you want to have the zoomToFullRoute() functionality in some cases, you'd need to add 

this.inherited(arguments);<SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

into the new function body along with a conditional statement.

About what you and Robert Scheitlin, GISP‌ said about when the map is automatically zoomed in or not: I've had exactly that issue and described it here: Zoom button and auto zoom in Directions widget. Maybe you could take a look at it and verify the problem.

Cheers,

Nik
