NgMap 设置标记颜色

Question

我在我的网络应用程序中使用ng-map。在地图视图中，我使用marker 显示不同的位置。我想根据我在对象内部获得位置的isOpned 字段来更改每个标记的颜色。我尝试将background-color 样式添加到我的标记中，但没有任何反应。

这是我的代码：

<ng-map zoom-to-include-markers="auto" 
         id="map"
         map-type-id="ROADMAP"
         street-view-control-options="{position: 'LEFT_CENTER'}">

   <marker ng-repeat="p in paths" position="{{p.positions}}"></marker>

</ng-map>

Answer 1

从ng maps 修改代码（因为帖子中没有添加示例代码）这是个好主意

Plunker演示

JS

var app = angular.module('myApp', ['ngMap']);

app.controller('mapController', function($interval) {
  var vm = this;
  vm.positions =[
    [40.71, -74.21], [40.72, -74.20], [40.73, -74.19], [40.74, -74.18],
    [40.75, -74.17], [40.76, -74.16], [40.77, -74.15], [40.77, -74.15]
  ];
var colorsDynamic=['ff8a80','880e4f','4a148c','311b92','3d5afe','76ff03','f57c00','5d4037']
  $interval(function() {
    var numMarkers = Math.floor(Math.random() * 4)+4; //between 4 to 8 markers
    vm.positions = [];
    vm.icon=[];//empty array of icon
    for (i = 0; i < numMarkers; i++) {
      var lat = 40.71 + (Math.random() / 100);
      var lng = -74.21 + (Math.random() / 100);
      vm.positions.push([lat, lng]);
      //pushing dynamic icon color
      vm.icon.push('http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|'+colorsDynamic[i]) 

    }
  }, 2000);
});

HTML

<div ng-controller="mapController as vm">
<ng-map zoom="14" center="[40.71, -74.21]">
  <marker ng-repeat="p in vm.positions track by $index" position="{{p}}" icon="{{vm.icon[$index]}}"></marker>
</ng-map>
