Does the direction widget support way points when initialized in JS API 3.x?

Question

Hi all,

I'm using the direction widget with esri javascript API  version 3.x.

I want to add some waypoint and get the directions.

How to implement this by the existing api?

I've tried to call the function of addStops and  addStop, it will add all of the stops into the directions widget and displayed as a stop.

Thanks,

Leo

Hi Leo,

what you describe can not be fulfilled with that widget while its designed exactly for that usecase. Also further hooking into existing Esri widgets is by my experience not a good idea.

For your intentions I only see the solution to get your data directly from the REST-service (RouteTask()) and build a nice little widget or module around it. We do this for most of our special needs that can`t be reached with out of the box esri widgets.

Hi Richard,

Thanks for your advice. Unfortunately, besides the symbols shown on the map, there also have direction details on the widget. This couldn't removed by your solution.

At the same time, the direction turns are calculated by the stops, which is not as expect either.

Hi Leo, if you just want wo hide the intermediate waypoimt marker you can first replace their symbol with a PictureMarkerSymbol with 0 size: var symbol = new PictureMarkerSymbol({ "url":"anyPicture.png", "height":0, "width":0, "type":"esriPMS" }); var directions = new Directions({ map: map, stopSymbol: symbol },"dir");‍‍‍‍‍‍‍‍‍‍ But there are remaining labels. Esri API seems to add them as SVG elements. I wasn`t able to remove them yet. Maybe svg.js or d3.js are helpful here. Is this what you are looking for?
