角谷歌，地图确实现在可以正确地显示，当它启动时是隐藏

本文介绍了角谷歌，地图确实现在可以正确地显示，当它启动时是隐藏的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

在地图隐藏的开始与NG-显示/ NG隐藏，它并没有显示正确一次看到。与标准地图相同的麻烦，只有我们可以调整大小发送给它的，因为我们有访问地图对象。

When map starts hidden with ng-show/ng-hide, it does not show correctly once visible. Same trouble with a standard map, only we can send a resize to it since we have access to the map object.

下面是与地图隐藏启动一个样本。按钮切换地图的可视性。

Here's a sample that starts with the map hidden. The button toggle the visibility of the map.

<!doctype html>
<html>
    <head>
        <style>
            .angular-google-map-container {
                width: 100%;
                height: 100px;
            }
            .mymap {
                width: 100%;
                height: 100px;
            }
        </style>
    </head>
    <body ng-app="app" ng-controller="myCtrl">
        <button ng-click="visible = !visible">ToogleMap</button>
        <div ng-show="visible">
            <google-map center="map.center" zoom="map.zoom"></google-map>
            <div class="mymap"></div>
        </div>
        <script src='https://ajax.googleapis.com/ajax/libs/angularjs/1.3.0-beta.8/angular.min.js'></script>
        <script src='http://maps.googleapis.com/maps/api/js?sensor=false'></script>
        <script src='http://underscorejs.org/underscore-min.js'></script>
        <script src='https://rawgithub.com/nlaplante/angular-google-maps/master/dist/angular-google-maps.min.js'></script>
        <script>
            var app = angular.module("app", ["google-maps"]);
            app.controller("myCtrl", function($scope, $timeout) {
                $scope.map = {
                    center: {
                        latitude: 45.4,
                        longitude: -71.9
                    },
                    zoom: 11
                };
                $scope.visible = false;
            }); 
        </script>
    </body>
</html>

随着谷歌JS地图，我会派一个resize到地图对象，但我没有访问它的角谷歌-地图。

With google-maps in js, I would send a resize to the map object, but I don't have access to it in angular-google-maps.

推荐答案

我找到了解决办法here

控件属性添加到谷歌地图标记：

Add a control attribute to the google-map tag:

<google-map
    center="mapOption.center"
    zoom="mapOption.zoom"
    control="myGoogleMap">
</google-map>

如果是，控制器，$ scope.myGoogleMap设为{}，当映射得到初始化它会被填满。之后，你可以使用$ scope.myGoogleMap.refresh（）来调整大小发送到地图！

Then in the controller, set $scope.myGoogleMap to {}, it will be filled when the maps get initialized. After that you can use $scope.myGoogleMap.refresh() to send a resize to the map !

下面是控制器的工作。

Here's the controller working.

app.controller("myCtrl", function($scope, $timeout) {
    $scope.mapOption = {
         center: {
             latitude: 45.4,
             longitude: -71.9
         },
         zoom: 11
    };
    $scope.visible = false;
    $scope.mapViewPosition = {};
    $scope.$watch("visible", function(newvalue) {
        $timeout(function() {
             var map = $scope.myGoogleMap.refresh();
        }, 0);
    });
});
