[英]Sencha Touch: Can't get map object from Ext.Map to give to the google directions service
我有一個Ext.Map對象,我試圖從中獲取google.maps.map()對象,但它沒有返回有效的對象,因此無法在地圖上呈現路線。
addMaps: function(options){
directionsDisplay =new google.maps.DirectionsRenderer();
directionsService = new google.maps.DirectionsService();
activeMarkers = new Array();
uconnPosition = new google.maps.LatLng(41.809929, -72.25486);
myMapPosition = new google.maps.LatLng(41.809929, -72.25486);
curBuildingPosition = new google.maps.LatLng(41.809929, -72.25486);
uconnMap = new Ext.Map({
mapOptions : {
center : new google.maps.LatLng(41.809929, -72.25486), //UConn
zoom : 16,
mapTypeId : google.maps.MapTypeId.ROADMAP,
navigationControl: true,
navigationControlOptions: {
style: google.maps.NavigationControlStyle.DEFAULT
}
},
plugins : [
new Ext.plugin.GMap.Tracker({
trackSuspended : true, //suspend tracking initially
highAccuracy : false,
marker : new google.maps.Marker({
position: uconnPosition,
title : 'My Current Location',
shadow: shadow,
icon : image
})
})
]
});
UConnApp.views.uconnTourMainPanel.add(uconnMap);
directionsDisplay.setMap(uconnMap.getMap()); //THIS IS WHERE I THINK THE PROBLEM IS
var org = new google.maps.LatLng(41.806501, -72.252769);
var dest = new google.maps.LatLng(41.805222,-72.254388);
var request = {
origin: org,
destination:dest,
travelMode: google.maps.TravelMode.WALKING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
})
},
這樣就可以毫無問題地創建地圖,但是當我嘗試將地圖對象發送到Google Maps路線服務時,它不會渲染到我的地圖上。 我已經嘗試了uconnMap.getMap()和uconnMap.map,但是還沒有從方向服務渲染到的對象中得到任何對象。 有人可以幫我嗎?
您需要使用以下代碼::
UConnApp.views.uconnTourMainPanel.add(uconnMap);
directionsDisplay.setMap(uconnMap.map); // Changed this line for you…
var org = new google.maps.LatLng(41.806501, -72.252769);
var dest = new google.maps.LatLng(41.805222,-72.254388);
var request = {
origin: org,
destination:dest,
travelMode: google.maps.TravelMode.WALKING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
})
現在一切正常。 我剛剛在我的應用中為您進行了測試:)
