我有一个工具栏按钮,单击该按钮应将我的地图更新到当前位置。我找不到此功能的工作示例,希望有人能给我建议。请参阅下面的示例代码 - 感谢您的帮助
地图:
Ext.define('MyApp.view.Myap', {
extend: 'Ext.Map',
alias: 'widget.mymap',
config: {
useCurrentLocation: false,
mapOptions:{
zoom: 9,
center: new google.maps.LatLng(42.2, -72.5),
mapTypeId: google.maps.MapTypeId.ROADMAP
},
listeners: {
maprender : function(comp, map){
google.maps.event.addListenerOnce(map, "idle", function () {
var host = window.location.origin ? window.location.origin : window.location.protocol + "/" + window.location.host;
var kmlOptions = {preserveViewport: false}
var now = +new Date();
var layer = new google.maps.KmlLayer(host + '/path/to.kml?timestamp=' + now, kmlOptions);
layer.setMap(map);
return layer;
});
},
}
},
})
工具栏按钮:
Ext.define('MyApp.view.btnLocateMe', {
extend: 'Ext.Button',
alias: 'widget.btnlocateme',
config: {
ui: 'normal',
iconCls: 'locate',
iconMask: true,
text: 'Locate Me',
listeners: [
{
fn: 'onButtonTap',
event: 'tap'
}
]
},
onButtonTap: function(button, e, options) {
//Produces error: cannot call method of undefined
currentLocation: new google.maps.LatLng(this._geo.getLatitude(), this._geo.getLongitude());
MyApp.view.MyMap.map.setCenter(currentLocation);
}
});
