Read clients lat/lon

[Poul Jensen]

Hi,

Can I read a clients lat/lon from his browser like Google does ?

Realise this probably needs javascript of which I know very little :-)

I guess I would place this somewhere in my login-procedure, but how do I get the lat lon from the javascript function and plug it into my sessionvariable ?

Cheers

I've use hidden fields to get values out of javascript when users log in. You just need to add a hidden field and a bit of code to the end of your javascript function:

document.[form name]_frm.[field equate].value = [javascript variable]

You can also use the NetTalk Javascript funtion SetSessionValue([value name], [javascript value]); and then read it in clarion using p_web.gsv([value name])

NetTalk also has location features built in though I haven't used it. You need to call p_web.GetLocation() at the start of the page, and then if the user accepts the data should be available in the following session variables on subsequent requests: _Longitude_, _Latitude_, _Altitude_, _Accuracy_, _AltitudeAccuracy_, _Heading_, _Speed_, _LocationUnixTime_, _LocationDate_=, _LocationTime_, _LocationError_.

This is the right answer;

>> NetTalk also has location features built in.
