Use es6 extends on bing classes ? RRS feed

  • Question

  • Hi,

    I'm trying to extend the Microsoft.Maps.PushPin classes from the BingMap API 7.0 using the javascript es6 'extends' method.

    class Marker extends Microsoft.Maps.PushPin {
        constructor(location, options) {
    	super(location, options);	// where location is an instance of Microsoft.Maps.Location	
        }
    }

    but it doesn't work, the object resulting of the command : new Marker(....) has the correct prototype but not the _location property. So I get an error when I try to add the marker on an EntityCollection.

    Uncaught TypeError: Cannot read property 'latitude' of undefined

    FYI, if I run the same code using new Microsoft.Maps.PushPin instead of new Marker, it work well.

    Is there a known issue with the extends method ?

  • Looking around the web it sounds like there is an issue with the extends method in ES6. Probably best to ask for help in an ES6 forum for this issue.
