我想知道地图上特定点的坐标。如果用户右键单击地图上的任何点，将出现显示坐标的警报。

该代码使用angularjs和ng-map模块。http://ngmap.github.io/

我认为您应该添加一个事件侦听器，然后像这样显示该事件内部的坐标：

<!DOCTYPE html>
<html ng-app="myApp">
<head>
<title>Simle Map</title>
<meta name="description" content="Simple Map">
<meta name="keywords" content="ng-map,AngularJS,center">
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<script src="https://maps.google.com/maps/api/js?libraries=placeses,visualization,drawing,geometry,places"></script>
<script src="https://code.angularjs.org/1.3.15/angular.js"></script>
<script src="https://rawgit.com/allenhwkim/angularjs-google-maps/master/build/scripts/ng-map.js"></script>
<script>
  var app = angular.module('myApp', ['ngMap']); 
  app.controller('EventDomListenerController', function($window) {
    var vm = this;
    vm.showAlert = function(event, args) {
      $window.alert(event.latLng.lat()+', '+event.latLng.lng());
    }
  });
</script>
</head>
<body ng-controller="EventDomListenerController as vm">
  <ng-map center="[40.74, -74.18]" on-click="vm.showAlert()"></ng-map>
</body>
</html>
