Google maps for AngularJS

问题

I am very new to AngularJS and I am trying to use https://github.com/angular-ui/angular-google-maps.

I am just trying to get the map to render on my page but I am getting an error message and I don't know what it means. Any help with understanding this error message would be appreciated.

I've created a plunk here:

github.com/twdean/plunk

Here is the Error in the browser:

Error: [$compile:multidir] Multiple directives [googleMap, markers] asking for new/isolated scope on: <google-map center="center" draggable="true" zoom="zoom" markers="markers" mark-click="true" style="height: 400px"> 

http://errors.angularjs.org/1.2.3/$compile/multidir?p0=googleMap&p1=markers&p2=new%2Fisolated%20scope&p3=%3Cgoogle-map%20center%3D%22center%22%20draggable%3D%22true%22%20zoom%3D%2

I suggest another alternative, ng-map.

I created a google maps angularjs directive called, ng-map, for my own project. This does not require any Javascript coding for simple functionality.

To Get Started

One. Download and include ng-map.js or ng-map.min.js

<script src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script src="dist/ng-map.min.js"></script>`

Two. use map tag, and optionally, control, marker, and shape tags

<ng-map zoom="11" center="[40.74, -74.18]">
  <marker position="[40.74, -74.18]" />
  <shape name="circle" radius="400" center="[40.74,-74.18]" radius="4000" />
  <control name="overviewMap" opened="true" />
</ng-map>`  

Examples

To use it in your app, simply include 'ngMap' as dependency to your app.

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

Hope it helps

-------------- EDIT -------------------

For those who looks for angular2 version,
there is also ng2-map https://ng2-ui.github.io/#/google-map

It seems that you're including a "markers" attribute within your google-map element.

Indeed as @Tyler Eich mentions, the docs as of Dec 5, 2013 remain outdated. Removing the marker attribute seems to make it work.

Here is how to display markers:

index.html

<div ng-controller="MapCtrl">
    <google-map id="mymap" 
            center="center" 
            zoom="zoom" 
            draggable="true"                                    
            mark-click="false">
            <markers>
                <marker ng-repeat="marker in markers" coords="marker">
                </marker>
            </markers>
    </google-map>
</div>

controller.js

var controller = module.controller('MapCtrl', function($scope) {
  $scope.myMarkers = [
      {
         "latitude":33.22,
         "longitude":35.33
      },
      ...
  ];

  $scope.center = {
      latitude: 33.895497,
      longitude: 35.480347,
  };

  $scope.zoom = 13;
  $scope.markers = $scope.myMarkers;
  $scope.fit = true;
});

I have just today had a need to implement a google map into my angular application. Since my implementation required something quite simple I decided to do this myself and create a simple directive. I will leave my source below for anyone who might find it usefull.

1. Create a directive
2. Create HTML
3. Optionally pass the coordinates through directive/controller if you need.

DIRECTIVE

angular.module('ngPortalApp')
  .directive('googleMap', function () {
    return {
      template: '<iframe width="100%" height="350" frameborder="0" style="border:0"></iframe>',
      restrict: 'E',
      scope: {
        pbcode: '='
      },
      link: function postLink(scope, element) {
        var mapFrame = element.find("iframe");
          if (scope.pbcode) {
            mapFrame.attr('src', "https://www.google.com/maps/embed?pb=" + scope.pbcode);
          }
          else {
            mapFrame.attr('src', '');
          }
      }
    };
  });

HTML

<div class="col-lg-12">
<google-map pbcode="'!1m0!3m2!1sen!2srs!4v1445332712674!6m8!1m7!1s34JkuBgIzmIJNmpFNThuUg!2m2!1d40.75816449978445!2d-73.98911289129973!3f175.51693470959802!4f7.069842517148402!5f0.7820865974627469'"></google-map>
</div>

Thats all there is to it. Remember that the google query string is called "pb" this is the code used in all embed codes you can grab from google. You may pass this to your directive straight up or if you need to via your controller or even through the directive itself. You can set any iframe map settings in the directive within the template.

To change between Street View or Map View you just send the corresponding code whichever source you are getting them from (db, json, etc).

For the above example:

Street Code:

!1m0!3m2!1sen!2srs!4v1445332712674!6m8!1m7!1s34JkuBgIzmIJNmpFNThuUg!2m2!1d40.75816449978445!2d-73.98911289129973!3f175.51693470959802!4f7.069842517148402!5f0.7820865974627469

Map Code:

!1m18!1m12!1m3!1d755.5452773113641!2d-73.98946157079955!3d40.75804119870795!2m3!1f0!2f0!3f0!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0x0000000000000000%3A0x1952a6258d36ecc5!2sMcDonald's!5e0!3m2!1sen!2srs!4v1445332854795

Haven't had any issues with this as yet. Here's a fiddle: jsFiddle

If you want to include markers you should do that in another element inside the google-maps directive. You should do something like:

<google-maps options="someOptionsObject"> 
<markers cords="someArrayWithLatitudeAndLongitudeCords"></markers>    
</google-maps>

For Angular2, there is angular2-google-maps. License as of 2016-05-14: MIT.
