我使用angularjs從Spring控制器和谷歌地圖API檢索數據來顯示地圖。 我點擊一個按鈕後調用控制器,然後顯示地圖,但它只顯示空白!谷歌地圖API不加載在單擊按鈕在Spring MVC
這是我的JSP代碼

這裏是JS:
var app = angular.module("MyApp", ["ui.bootstrap.modal"]);
app.controller("MyCtrl", function($scope,$http) {
var urlBase="http://localhost:8080/TaskManagerApp";
$scope.showModal = false;
$http.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded";
$scope.openMap = function() {
$http.get(urlBase+'/drawmap').
success(function(data) {
drawMap(JSON.stringify(data));
});
$scope.showModalMap = true;
};
function draWMap(mapdata){
var markers = mapdata;;
var mapOptions = {
center: new google.maps.LatLng(markers[0].lat, markers[0].lng),
zoom: 10,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("dvMap1"), mapOptions);
var infoWindow = new google.maps.InfoWindow();
var lat_lng = new Array();
var latlngbounds = new google.maps.LatLngBounds();
for (i = 0; i < markers.length; i++) {
var data = markers[i]
var myLatlng = new google.maps.LatLng(data.lat, data.lng);
lat_lng.push(myLatlng);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: data.title
});
latlngbounds.extend(marker.position);
(function (marker, data) {
google.maps.event.addListener(marker, "click", function (e) {
infoWindow.setContent(data.description);
infoWindow.open(map, marker);
});
})(marker, data);
}
map.setCenter(latlngbounds.getCenter());
map.fitBounds(latlngbounds);
//***********ROUTING****************//
//Initialize the Path Array
var path = new google.maps.MVCArray();
//Initialize the Direction Service
var service = new google.maps.DirectionsService();
//Set the Path Stroke Color
var poly = new google.maps.Polyline({ map: map, strokeColor: '#4986E7' });
//Loop and Draw Path Route between the Points on MAP
for (var i = 0; i < lat_lng.length; i++) {
if ((i + 1) < lat_lng.length) {
var src = lat_lng[i];
var des = lat_lng[i + 1];
path.push(src);
poly.setPath(path);
service.route({
origin: src,
destination: des,
travelMode: google.maps.DirectionsTravelMode.DRIVING
}, function (result, status) {
if (status == google.maps.DirectionsStatus.OK) {
for (var i = 0, len = result.routes[0].overview_path.length; i < len; i++) {
path.push(result.routes[0].overview_path[i]);
}
}
});
}
}
}
});
數據傳遞給drawMap(屬於MapData)低於: [ { 「標題」: 「Alibaug」, 「lat」:「10.641400」, 「lng」:「72.872200」, 「描述」: 「測試DESC1」 } , { 「標題」: 「孟買」, 「LAT」: 「18.964700」, 「LNG」: 「72.825800」, 「說明」:「測試DESC2 「 } , { 」標題「: 」普納「, 」LAT「: 」18.523600「, 」LNG「: 」73.847800「, 」說明「: 」測試Desc3「 } ]
如果我硬編碼t他的數據,它工作正常。但在這種情況下,它不會幫助我!
