第一次使用angular-google-maps.我很困惑如何绘制多边形并抓取该区域中的所有邮政编码.我不知道该怎么做.以下是我的代码
<div ng-app="myapp" ng-controller="mapsController">
<!--It displays the markers links-->
<div class="locations">
<ul>
<li ng-repeat="l in locations" ng-click="ShowLocation(l.LocationID)"><a href="#">{{l.Title}}</a></li>
</ul>
</div>
<div class="maps">
<!-- Add directive code (gmap directive) for show map and markers-->
<ui-gmap-google-map style="Box-shadow:2px 2px 2px 2px lightgrey" center="map.center" zoom="map.zoom">
<ui-gmap-marker ng-repeat="marker in markers" coords="marker.coords" options="marker.options" events="marker.events" idkey="marker.id">
<ui-gmap-window options="windowOptions" show="windowOptions.show">
<ui-gmap-drawing-manager options="drawingManagerOptions" control="drawingManagerControl"></ui-gmap-drawing-manager>
</ui-gmap-window>
</ui-gmap-marker>
</ui-gmap-google-map>
</div>
</div>
在我的script.js中,我编写了以下代码
var app = angular.module('myapp',['uiGmapgoogle-maps']); //dependency we should add to angular application
app.controller('mapsController',function ($scope,uiGmapGoogleMapApi) {
//this is default coordinates for the map when it loads for first time
$scope.map = {
center: {
latitude: 41.850033,longitude: -87.6500523
},zoom: 4,polygons: [],isDrawingModeEnabled: true,bounds: {}
};
$scope.markers = [];
$scope.locations = [];
$scope.windowOptions = {
show: true
};
$scope.options = {
scrollwheel: false
};
uiGmapGoogleMapApi.then(function (maps) {
$scope.drawingManagerOptions = {
drawingMode: google.maps.drawing.OverlayType.MARKER,drawingControl: true,drawingControlOptions: {
position: google.maps.ControlPosition.TOP_CENTER,drawingModes: [
google.maps.drawing.OverlayType.MARKER,google.maps.drawing.OverlayType.CIRCLE,google.maps.drawing.OverlayType.POLYGON,google.maps.drawing.OverlayType.POLYLINE,google.maps.drawing.OverlayType.RECTANGLE
]
},circleOptions: {
fillColor: '#ffff00',fillOpacity: 1,strokeWeight: 5,clickable: false,editable: true,zIndex: 1
}
};
$scope.markersAndCircleFlag = true;
$scope.drawingManagerControl = {};
$scope.$watch('markersAndCircleFlag',function () {
if (!$scope.drawingManagerControl.getDrawingManager) {
return;
}
var controlOptions = angular.copy($scope.drawingManagerOptions);
if (!$scope.markersAndCircleFlag) {
controlOptions.drawingControlOptions.drawingModes.shift();
controlOptions.drawingControlOptions.drawingModes.shift();
}
$scope.drawingManagerControl.getDrawingManager().setOptions(controlOptions);
});
})
}).config(function (uiGmapGoogleMapApiProvider) {
uiGmapGoogleMapApiProvider.configure({
libraries: 'drawing,geometry,visualization'
});
});
//var latlng = new google.maps.LatLng(37.09024,-95.712891);
//latitude: 41.850033,longitude: -87.6500523
这只显示了一个缩放的谷歌地图,甚至没有绘制任何内容.请帮忙.我注意到的一件事是！$scope.drawingManagerControl.getDrawingManager在if条件中变为true并返回.
我认为你应该退后一步,寻找你真正想要实现的目标.
如果你想学习角度,谷歌地图,或两者兼而有之,我认为你不是在正确的道路上.
首先,您使用的库不再由其创建者维护.即使他们建议使用备用选项：

对于他们展示的两个选项,我将推荐第二个：angular-google-maps
该库将与Angular2一起使用.如果您正在寻求学习新技术,您应该致力于技术提升. Angularjs虽然是一个非常好用的库,但它是Angular2的前身,随着时间的推移,它将不那么受欢迎.
话说回来;我注意到你没有在地图中声明任何标记或位置.因此,没有数据设置在地图中显示.这就是为什么你只看到一张空地图.
$scope.markers = []; $scope.locations = [];
我建议您在尝试之前尝试理解您尝试实现的代码的逻辑,并使其在天空中工作.
