Methods

bindTo

Stability: experimental

The bindTo method allows you to set up a two-way binding between a source and target object. The method returns an ol.ObjectAccessor with a transform method that lets you transform values on the way from the source to the target and on the way back.

For example, if you had two map views (sourceView and targetView) and you wanted the target view to have double the resolution of the source view, you could transform the resolution on the way to and from the target with the following:

sourceView.bindTo('resolution', targetView)
  .transform(
    function(sourceResolution) {
      // from sourceView.resolution to targetView.resolution
      return 2 * sourceResolution;
    },
    function(targetResolution) {
      // from targetView.resolution to sourceView.resolution
      return targetResolution / 2;
    }
  );

Parameters:

Name	Type	Argument	Description
key	string		Key name.
target	ol.Object		Target.
targetKey	string	<optional>	Target key.
