我的尝试：
我试过使用ng-haversine模块。下面是ng-haversine的脚本。
What I have tried:
I tried by using ng-haversine module .below is the script of ng-haversine.
// Code goes here
/**
* @name ng-haversine
* @version 0.0.1
* @license MIT
* @author Diego Herrera
* @description ng-haversine is an AngularJS module that applies the Haversine formula to a pair of coordinates to calculate the distance between them.
*/
!function(t){"use strict";t&&t.angular?angular.module("dahr.ng-haversine",[]).service("$haversine",function(){var t=6378137,a=function(t){return t*Math.PI/180};this.distance=function(n,e){var r=a(e.latitude-n.latitude),i=a(e.longitude-n.longitude),o=Math.pow(Math.sin(r/2),2)+Math.cos(a(n.latitude))*Math.cos(a(e.latitude))*Math.pow(Math.sin(i/2),2),s=2*Math.atan2(Math.sqrt(o),Math.sqrt(1-o));return t*s}}):t.console.error("ng-haversine: AngularJS must be loaded first. More info at https://angularjs.org/.")}(window);
推荐答案
范围演示：< / h1>
< div ng-controller =myController>
{{distance}}
< / div>
< script>
var ngApp = angular.module（myNgApp，[dahr.ng-haversine]）;
ngApp.controller（'myController'，函数（
scope Demo: </h1> <div ng-controller="myController"> {{distance}} </div> <script> var ngApp = angular.module("myNgApp",["dahr.ng-haversine"]); ngApp.controller('myController', function (
范围）{
var coord1 = {
latitude：40.4169473，
经度：-3.7057172
};
var coord2 = {
纬度：40.4236942，
经度：-3.7109793
};
var distance =
scope) { var coord1 = { "latitude": 40.4169473, "longitude": -3.7057172 }; var coord2 = { "latitude": 40.4236942, "longitude": -3.7109793 }; var distance =
haversine.distance（coord1，coord2）;
haversine.distance(coord1, coord2);
