javascript - Save drawn polygon in googlemaps api -


hello guys try save drawn polygon google map api , , don't know how.i want save polygon(coordinates, or path , send them in form .this have until now, tried read documentation can't understand much.

<script>     function initmap() {         var map = new google.maps.map(document.getelementbyid('map'), {             center: {lat: 46.435812, lng: 27.639917},             zoom: 17,             maptypeid: 'hybrid'});         var drawingmanager = new google.maps.drawing.drawingmanager({            drawingmode: google.maps.drawing.overlaytype.marker,            drawingcontrol: true,            drawingcontroloptions: {                position: google.maps.controlposition.top_center,                drawingmodes: ['polygon']            },        });         drawingmanager.setmap(map);     }; </script>

edit:

<script async defer src="https://maps.googleapis.com/maps/api/js?key=aizasybr0yeeoubwc8qytig79dmhfozxr44wx5w&libraries=geometry,drawing&callback=initmap"></script>

for polygon, same thing done in similar question: saving coordinates , data google maps in database, use appropriate event polygon (polygoncomplete) , process through path, adding coordinates appropriate form field:

google.maps.event.addlistener(drawingmanager, 'polygoncomplete', function(polygon) {   var coordstr = "";   (var = 0; < polygon.getpath().getlength(); i++) {     coordstr += polygon.getpath().getat(i).tourlvalue(6) + ";";     console.log(coordstr);     document.getelementbyid('coords').value = coordstr;   } });

proof of concept fiddle

code snippet:

function initmap() {    var map = new google.maps.map(document.getelementbyid('map'), {      center: {        lat: 46.435812,        lng: 27.639917      },      zoom: 17,      maptypeid: 'hybrid'    });      var drawingmanager = new google.maps.drawing.drawingmanager({      drawingmode: google.maps.drawing.overlaytype.polygon,      drawingcontrol: true,      drawingcontroloptions: {        position: google.maps.controlposition.top_center,        drawingmodes: ['polygon']      },    });    google.maps.event.addlistener(drawingmanager, 'polygoncomplete', function(polygon) {      var coordstr = "";      (var = 0; < polygon.getpath().getlength(); i++) {        coordstr += polygon.getpath().getat(i).tourlvalue(6) + ";";      }      document.getelementbyid('coords').value = coordstr;    });    drawingmanager.setmap(map);  };  google.maps.event.adddomlistener(window, "load", initmap);
html,  body,  #map {    height: 100%;    width: 100%;    margin: 0px;    padding: 0px  }
<script src="https://maps.googleapis.com/maps/api/js?libraries=drawing"></script>  <input id="coords" style="width:600px" />  <div id="map"></div>

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
