Introduction
When we have to deal with address forms, usually we have to fill the street name, street number, postal code, etc.
And it’s sometimes repetitive and can take more time to fulfill a simple form.
Here is a simple control using Google map to automatically complete your address forms.
Background
First is JQuery control that you can include in web page that will help a user automatically fill an address form when he begins typing the address.
Second is an Angular module with directives for drawing a map with markers, a directive for geocoder that helps for searching places on Gmap and finally address form auto complete.
Using the Code
JQuery Address Form Auto Complete
Here is a simple JQuery control used with a Google map v3 API that will automatically fill an address form.
You can include it directly in your web page or separately in JavaScript file. This example is with a full page:

AngularJS Module for Google map, Geocoder, Address Auto Complete
Here is an AngularJs module with a set of directives that you can inject in your Angular application to get address auto complete, draw Google map and search addresses on the map (geocoder).
There also Angular-ui module for Google map which is more complete but also complex. The code here is simple and you can modify it as per your convenience.
ngMap: This directive is for drawing the map and as parameters you have:
markers: An array of markerscenter: The map center on page load- and other parameters that you can see here in the code
ngGeocoder: that you can use to search for addresses on the mapngAddressAutocomplete: A directive to auto complete address form
And here is a full example with a single html page.

Conclusion
This is a useful control to auto complete an address form and search places on Google map. Hope this will help.
