我在 AngularJS 中使用 ng-map 指令。我有以下代码来生成标记。我将每个标记保存在数组 lat 和 long 中,如示例(https://ngmap.github.io/#/!marker_with_ng_repeat_dynamic.html),我可以在日志中看到信息是正确的。但没有添加到我的地图中。

这是我的 AngularJS 代码:

var app = angular.module('myApp', ['ngMap']);
app.controller('mapController', function($interval, $http) {
    var generateMarkers = function() {
        var vm = this;
        vm.positions = [];
        $http.get("data").
            success(function(data) {
            console.log(data);
            console.log("length array" + data.length);
            for (i = 0; i < data.length; i++) {
                var lat = parseFloat(data[i].latitud);
                var lng = parseFloat(data[i].longitud);
                console.log("pos: " +lat + lng);
                vm.positions.push([lat, lng]);
                console.log("vm.positions", vm.positions);
            }   
        }).
        error(function (data) {
            console.log("fallo");
        });
    };
  $interval(generateMarkers, 20000);
});

还有我的 HTML 代码:

 <ng-map zoom="14" center="[42.8169, -1.6432]" default-style="false">
  <marker ng-repeat="p in vm.positions" position="{{p}}"></marker>
</ng-map>

这里是我的日志:

这里的plnkr:http ://plnkr.co/edit/5uGUeyeuAie0TAFzIHMo?p=preview 和例子类似,但是增加了一个GET请求来获取一个lat和lng值的数组。我更新了删除 GET 请求并更新数据值的 plnk。

您在函数中获取以下代码,请将其从函数中取出。

var vm = this;
vm.positions = [];
