javascript - google map api v3 - how to limit number of polygon lines and force closure at the 5 click? -

-

i have code

<script>     function initialize() {         var mapoptions = {             center: new google.maps.latlng(-34.397, 150.644),             zoom: 8         };          var map = new google.maps.map(document.getelementbyid('map-canvas'),             mapoptions);          var drawingmanager = new google.maps.drawing.drawingmanager({             drawingmode: google.maps.drawing.overlaytype.marker,             drawingcontrol: true,             drawingcontroloptions: {                 position: google.maps.controlposition.top_center,                 drawingmodes: [                     google.maps.drawing.overlaytype.polygon                 ]             },             polygonoptions: {                 draggable: true,                 editable: true,                 strokecolor: "#000",                 strokeweight: "2"             }         });         drawingmanager.setmap(map);      }     google.maps.event.adddomlistener(window, 'load', initialize); </script>

and trying limit number of polygon lines 5 , 5 click force closure of polygon shape.

i unable find direction solve problem.. if u have link resource or ideas how - good!

one option: don't use drawingmanager. build polygon , keep track of markers added.

var poly; var map;  function initialize() {   var polyoptions = {       strokecolor: '#000000',       strokeopacity: 1.0,       strokeweight: 3, map: map     };   poly = new google.maps.polygon(polyoptions);   var bounds = new google.maps.latlngbounds();   map = new google.maps.map(document.getelementbyid('map_canvas'), {     center: new google.maps.latlng(10.9386, -84.888),     zoom: 10,     maptypeid: google.maps.maptypeid.roadmap   });   var evtlistnr = google.maps.event.addlistener(map,"click",function(evt) {     bounds.extend(evt.latlng);     addlatlng(evt);     if (poly.getpath().getlength() == 5) {       google.maps.event.removelistener(evtlistnr);     }   });        poly.binder = new mvcarraybinder(poly.getpath());    poly.setmap(map); }

proof of concept
