I am using the ArcGIS API for Javascript and am wondering if it comes with functionality for zooming out using a rectangle, similar to the behavior in ArcGIS Desktop? Specifically, the user draws a rectangle and it zooms out based on that rectangle.

I can create the functionality myself, but was wondering if it already existed in the API...

Yes, it is built into the API. You just need to set up a navigation controller first:

navController = new esri.toolbars.navigation(yourMap)
navController.activate(Navigation.ZOOM_OUT);

The API has a Navigation toolbar class that uses this functionality.

It comes with a zoom out tool that works by drawing a box.

There is a sample page here.

  • Cool, thanks. Do you know if I need to use their toolbar to get that functionality, or can I just use the functionality in my own UI?

  • Thanks. I tinkered around and was able to use the navigation API without using any of the DOJO UI stuff. Did the trick!
