Using Google Maps API to get Address of Business_问答_开发者

I have a requirement and I am hoping Google Maps API will have a solution. I have never used Google Maps API - so I am very new to this.

On the website homepage there is a form, when a user comes, I want the following things to happen:

1) The city field should be populated with users city based on IP

2) There is a second field called store name - when the user starts typing the store name - I want to fetch all business listings with that name in that city and show it as a drop down from which the user can select the appropriate branch. There is no need for anything to be shown on the map. Egs - If a user in houston starts typing McDonalds, the following business listings should start showing up

McDonalds, 12 Pearland Ave, Houston TX
McDonalds, 2600 Bary Area Blvd, Houston TX
McDonalds, 262 Clearlake Blvd, Houston TX

Also when we get the address for a business listing from Go开发者_运维问答ogle API - do we get it as one String and we need to parse it or do we get it different fields Street Name, City, State, Zip code etc

Any information or examples will be really appreciated Thanks

I don't think you want Google Maps. First of all the terms of use do not allow any use other than displaying things on a Google Map on a publicly accessible webpage, second, there is another Google API that does exactly what you need: the Client location API: http://code.google.com/apis/ajax/documentation/#ClientLocation

Concerning the "businesses": You're going to have to source that data from somewhere - I do not believe google has a service for that. Perhaps you could simply use the Google Search API and some logic to find only businesses (http://code.google.com/apis/ajaxsearch/)

EDIT: I for the businesses, perhaps you could take a look at this sample: http://code.google.com/apis/ajaxsearch/samples.html#local-search

updated: here is an example of using the google clientlocation api and localsearch using jsonp.

If you're only looking up restaurants, try using Yelp's API. You can search for a business by its name within a search radius. Their API is also simpler and easier to use than google's.
