问题
Is there a way to find a clients location on a website using just jQuery. For example, if a user comes to my site, how could I find out what their approximate location is just using jQuery. For example, if a user came from San Francisco CA it would have some type identifier to let me know the user came from San Francisco CA. I wouldn't really need their exact location just the county or general area of origin.
edit: How is the information on http://flourishworks-webutils.appspot.com/req generated?
Thanks

To get the client IP address & country name in jQuery:
$.getJSON("http://freegeoip.net/json/", function(data) {
var country_code = data.country_code;
var country = data.country_name;
var ip = data.ip;
var time_zone = data.time_zone;
var latitude = data.latitude;
var longitude = data.longitude;
alert("Country Code: " + country_code);
alert("Country Name: " + country);
alert("IP: " + ip);
alert("Time Zone: " + time_zone);
alert("Latitude: " + latitude);
alert("Longitude: " + longitude);
});
$.get("http://freegeoip.net/json/", function (response) {
$("#ip").html("IP: " + response.ip);
$("#address").html("Location: " + response.city + ", " + response.region_name);
$("#details").html(JSON.stringify(response, null, 4));
}, "jsonp");<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

You can use a web service that supports JSONP, such as my service http://ipinfo.io. It'll provide you with the client's IP address, hostname, geolocation information and network owner. Here's an example of it in action with jQuery:
$.get("http://ipinfo.io", function(response) {
$("#ip").html(response.ip);
$("#address").html(response.city + ", " + response.region);
}, "jsonp");
Here's a more detailed JSFiddle example that also prints out the full response information, so you can see all of the available details: http://jsfiddle.net/zK5FN/2/

The HTML5 Geolocation API allows you to get a user's Latitude/Longitude with some JavaScript (if the browser is compatible, and if the user allows access to his/her location).
You can then reverse-geocode the location to get an address, there are several free reverse-geocoding services other than Google's API.
However, if you don't need accurate location, and if you want all your users to take advantage of the feature (no matter the browser), and if you don't want to ask them whether they allow your site to have their location, I would recommend to use your user's IP to get the location.

I created the ipdata.co API to provide a solid solution to this, see the below fiddle to play with. It returns numerous useful datapoints, such as - location: country (name and code), region, city etc., ecommerce - currency_code, currency symbol, timezone, mobile carrier data and it detects whether the IP address is a Proxy or a Tor user.
Ipdata has 10 global endpoints each able to handle >10,000 requests per second.
This answer uses a 'test' API Key that is very limited and only meant for testing a few calls. Signup for your own Free API Key and get up to 1500 requests daily for development.
$.get("https://api.ipdata.co?api-key=test", function (response) {
$("#ip").html("IP: " + response.ip);
$("#city").html(response.city + ", " + response.region);
$("#response").html(JSON.stringify(response, null, 4));
}, "jsonp");<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Any client side option is not a good idea, because they are provided by the computer based on the wireless networks around. I bet that 90% of desktop users don't have this feature activated. When you get to a website that want your location, you have to click a button to agree to. If they just got on your website, then they want to know first why you need their location.
A good way is to show them a page to inform them why you need their location and that you will never use it for any other purposes than the specified one, and the location will not be saved in your database.
If there is a script that runs server side, then there is a connection from the client to the server. In this case the Server must know the IP Address. There is a trick that you can do to get the IP Address first.
Make a php script on your server, that will return only the IP Address. Since the jquery is processed locally, when a connection is made to the server, the client IP Address will be disclosed. It will take some additional time to make the required connections but soon the IP Address will be available in jQuery.
Then, you can call trough jquery an external API that will give you information for that specific IP Address. Either you buy an IP Database and install it on your websserver so you can call it, either you use another API. You can check http://www.ipgp.net/ip-address-geolocation-api/

This is possible with https://ip-api.io geo location API. It provides country, city, zip code, coordinates, network, ASN, timezone. For example with jQuery:
$(document).ready( function() {
$.getJSON("http://ip-api.io/api/json",
function(data){
console.log(data);
}
);
});
Also https://ip-api.io checks TOR, public proxy and spammer databases and provides this information as well.
Example response:
{
"ip": "182.35.213.213",
"country_code": "US",
"country_name": "United States",
"region_code": "CA",
"region_name": "California",
"city": "San Francisco",
"zip_code": "94107",
"time_zone": "America/Los_Angeles",
"latitude": 32.7697,
"longitude": -102.3933,
"suspicious_factors": {
"is_proxy": true,
"is_tor_node": true,
"is_spam": true,
"is_suspicious": true // true if any of other fields (is_proxy, is_tor_node, is_spam) is true
}
}
