A composite demo this one; incorporating two markers, a polyline, and one of Mapstractions built-in functions to work out the distance between where I live (London) and where I work (Berlin). that's it.
JavaScript Demo Source: mxn-home-and-work.js
var mapstraction; function initialize() { var home = new mxn.LatLonPoint(51.4323, -0.3478); var work = new mxn.LatLonPoint(52.5307, 13.4110); var somewhere = new mxn.LatLonPoint(51.516, 7.46); var connector = new mxn.Polyline([home, work]); var homeMarker = new mxn.Marker(home); var workMarker = new mxn.Marker(work); connector.setWidth(3); mapstraction = new mxn.Mapstraction('map', 'ovi'); mapstraction.addControls ({ pan: true, zoom: 'large', map_type: true }); mapstraction.addMarkerWithData (homeMarker, { infoBubble : "Where I Live", draggable : false, hover : true }); var bubbleText = "Where I Work (" + (work.distance(home).toFixed(1) * 0.6) + " miles away)"; mapstraction.addMarkerWithData (workMarker, { infoBubble : bubbleText, draggable : false, hover : true }); homeMarker.openBubble(); workMarker.openBubble(); mapstraction.addPolyline(connector); mapstraction.setCenterAndZoom(somewhere, 5); }
