Google Maps API Development get coordinates and street details

Your project has the need to get the coordinates of the current click or to get information about the current street.
Estimate this for the novice, or is more troublesome, because from the official internet to find this is not very easy to find, to look for a long time, good luck may be found in a sudden.

Give yourself a test case. The code is as follows:

<! DOCTYPE html>html, body {height:100%; Margin:0; padding:0; } #map {height:100%; }    </style>functionInitmap () {varMYLATLNG ={lat:39.921323, LNG:116.426239            }; varmarker; varMarkersarray = []; varMap =NewGoogle.maps.Map (document.getElementById (' Map ')), {zoom:12, center:mylatlng}); //----Google Hide----            varIsfirstload=true; //the callback after the map tile loading is completeGoogle.maps.event.addListener (map, ' tilesloaded ',function () {            if(isfirstload) {Hidelogo (); Isfirstload=false;            }               }); functionHidelogo () {$ ("#map. GM-STYLE-CC"). Hide (); $("#map [title= ' Click to view this area on Google maps]"). Hide (); }            //----Google Hide----Map.addlistener (' click ',function(e) {addmarker (e.latlng, map); //get current geographic information based on latitude and longitude                varLatlngdata = E.latlng.lat (). toFixed (6) + ', ' +e.latlng.lng (). toFixed (6); Console.log (Latlngdata) $.ajax ({type:"POST", URL:"Https://maps.googleapis.com/maps/api/geocode/json?latlng=" +latlngdata+ "&location_type=rooftop&result_ Type=street_address&key=aizasyc8ixpngfa7ud-xb0jeqhkedb7j3gbgoie ", Async:true, Success:function(data) {Console.log (data)varsite = latlngdata+ ' <br/> ' +data.results[0].formatted_address; Console.log (site)varInfowindow =NewGoogle.maps.InfoWindow ({content:site}); Infowindow.open (Map,marker); //pop-up message prompt window                    }                });            }); //Add Coordinate Object            functionAddmarker (latlng, map) {if(markersarray.length>0) {markersarray[0].setmap (NULL);                }; Markersarray.shift (marker) marker=NewGoogle.maps.Marker ({position:latlng, map:map});            Markersarray.push (marker); }        }    </script> <script src= "http://libs.baidu.com/jquery/1.9.0/jquery.js" ></script> <script src= " Https://maps.googleapis.com/maps/api/js?key=AIzaSyC8IXpNgfA7uD-Xb0jEqhkEdB7j3gbgOiE&callback=initMap "Async Defer></script></body>$ (window). Load (function(){        //$ ("#map [title= ' Click to view this area on Google Maps ']"). Hide ();        //$ ('. gm-style-cc '). Hide ();    });</script>

注意: Please introduce yourself to the local jquery, because to use the AJAX request, Google's geo-service interface.

The core of the code is the URL of the request:

URL: "https://maps.googleapis.com/maps/api/geocode/json?latlng=" &location_type=ROOFTOP& "+latlngdata+" Result_type=street_address&key=aizasyc8ixpngfa7ud-xb0jeqhkedb7j3gbgoie "

This is a latitude reverse geocoding, the URL has four parameters:,,, and latlng location_type result_type key Detailed concepts and parameters, please refer to the next chapter of the Google Maps API development Geocoding API
