how to place a bubble on map using geolocation with onlocationupdatate event

[naseerkhan]

Hi friends i did a small program on placing a bubble on current location using updatelocation event but it shows only default location and also it does not place a bubble on that location.

My code is

first.js
=====

MapView = Ext.extend(Ext.Panel, {
layout: 'card',
initComponent: function() {
this.map = new Ext.Map({
useCurrentLocation: true,
mapOptions : {
zoom: 12,
navigationControlOptions: {
style: google.maps.NavigationControlStyle.SMALL
}
},
geo: new Ext.util.GeoLocation({
autoUpdate: false,
timeout: 1000,
listeners: {
locationupdate: this.onLocationUpdate,
scope: this,
locationerror: function(geo) {
console.log('Location update error.');
}
}
})
});

this.items = this.map;

MapView.superclass.initComponent.call(this);
},


onLocationUpdate: function(geo) {
var position = new google.maps.LatLng(geo.latitude, geo.longitude);




var infowindow = new google.maps.InfoWindow({
content: 'test info text'
});

var marker = new google.maps.Marker({
position: position,
title : 'Your location!',
map: this.map
});
}
});

It does not work properly. It does not show current location and also it doesnot place a bubble.

Pls help me because i am new to this technology.

And also i have one small doubt i.e

when a person moving from one location to another location then automatically a bubble has to place at that location with the given time and also i need to draw a line among those bubbles.


pls help me this is urgent for me.



Thanks and Regards,

Has the maprender event fired when the location is found?

[naseerkhan]

Map displayed with default location. It calls only locationerror event but it is not reaching locationupdate event

thats why it shows default location.

I have one doubt i.e how to find whether maprender event has fired or not?

I tried so many examples which are placed in the forum but those also not working

I tested it on emulator only but i didn't test it in mobile.

Pls tell me the solution for this.


Thank in advance.

Ext.Map will fire a maprender event. You shouldn't try to add a marker or anything to the map until that is fired.
