我正在使用视图在地图上显示一个位置,并在其下方有一个小表单来获取用户地址(如果他们想要方向)。地图最初按我的意愿呈现。有一个控制器可以处理点击按钮并使用路线更新显示。我可以看到它正在成功检索路线信息。它只是不更新显示来显示它。我错过了什么?
这是视图:
var tcmlatlng = new google.maps.LatLng(38.898748, -77.037684);
Ext.define('VisitTCMIndy.view.Directions',{
extend: 'Ext.Panel',
requires: [
'Ext.form.Panel',
'Ext.Map'
],
config: {
layout: 'vbox',
items: [
{
xtype: 'map',
useCurrentLocation: false,
flex: 3,
mapOptions: {
center: tcmlatlng,
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP
},
listeners: {
maprender: function(map,gmap,options){
var homemarker = new google.maps.Marker({
position: tcmlatlng,
map: gmap
});
}
}
},
{
xtype: 'formpanel',
id: 'directionsform',
flex: 1,
items:[
{
xtype: 'textfield',
name: 'address',
label: 'Address',
},
{
xtype: 'button',
ui:'action',
text: 'Get Directions'
}
]
}
]
}
});
这是控制器
Ext.define('VisitTCMIndy.controller.Directions',{
extend: 'Ext.app.Controller',
config: {
control: {
dButton: {
tap: 'loaddirections'
}
},
refs: {
dButton: '#directionsform button[ui=action]',
tcmmap:'map',
addfield:'textfield[name=address]'
}
},
loaddirections: function(dbutton){
console.log('loaddirections');
var gmap = this.getTcmmap();
var directionsDisplay = new google.maps.DirectionsRenderer();
var directionsService = new google.maps.DirectionsService();
directionsDisplay.setMap(gmap.map);
var tcmadd = "1600 Pennsylvania Ave, Washington, DC";
var originadd = this.getAddfield().getValue();
var request = {
origin: originadd,
destination: tcmadd,
travelMode: google.maps.TravelMode.DRIVING
};
directionsService.route(request, function(result, status){
console.log(status);
if(status = google.maps.DirectionsStatus.OK){
console.log(result);
directionsDisplay.setDirections(result);
}
});
}
});
