copied!<p>Here is some code (for the Google Maps JavaScript API version 3) that achieves what you want. It supports:</p> <ul> <li>clicking to append vertices.</li> <li>clicking on the first vertex again to close the path.</li> <li>dragging vertices.</li> </ul> <p>It's undocumented, but hopefully you can see what it's doing easily enough.</p> <pre><code>$(document).ready(function () { var map = new google.maps.Map(document.getElementById('map'), { center: new google.maps.LatLng(21.17, -86.66), zoom: 9, mapTypeId: google.maps.MapTypeId.HYBRID, scaleControl: true }); var isClosed = false; var poly = new google.maps.Polyline({ map: map, path: [], strokeColor: "#FF0000", strokeOpacity: 1.0, strokeWeight: 2 }); google.maps.event.addListener(map, 'click', function (clickEvent) { if (isClosed) return; var markerIndex = poly.getPath().length; var isFirstMarker = markerIndex === 0; var marker = new google.maps.Marker({ map: map, position: clickEvent.latLng, draggable: true }); if (isFirstMarker) { google.maps.event.addListener(marker, 'click', function () { if (isClosed) return; var path = poly.getPath(); poly.setMap(null); poly = new google.maps.Polygon({ map: map, path: path, strokeColor: "#FF0000", strokeOpacity: 0.8, strokeWeight: 2, fillColor: "#FF0000", fillOpacity: 0.35 }); isClosed = true; }); } google.maps.event.addListener(marker, 'drag', function (dragEvent) { poly.getPath().setAt(markerIndex, dragEvent.latLng); }); poly.getPath().push(clickEvent.latLng); }); }); </code></pre>
