Need advise on Google API

[lukesayaw]

Hi,

I am working on a project that includes the integration of a google api. The application is supposed to pinpoint the location of a user using the google api. Currently I am looking at the guide sample application and found that the latitude and longitude have to be supplied first to get the information of a particular location. In my application, the latitude and longitude of a user's location have to be automatically supplied in order to determine the location of the user. I would like to know how to detect the location of a user automatically.

So please give me some advise and guide me in the right direction with regard to the application.

Many Thanks

You can use the Ext.util.GeoLocation class to get the current latitude and longitude of the user's device. There's an example of it's usage in the API documentation:

Hi,

I am just wondering the difference between Ext.Map found in the "guide" example and Ext.util.GeoLocation? Do they provide the same latitude and longitude information of a device?

Thanks.

They are different things, from the docs:

Ext.Map


Wraps a Google Map in an Ext.Component.


Ext.util.GeoLocation


Provides a cross browser class for retrieving location information.

Based on the Geolocation API Specification.
If the browser does not implement that specification (Internet Explorer 6-8), it can fallback on Google Gears as long as the browser has it installed, and the following javascript file from google is included on the page...
