Javascript Form Input - GPS - GeoLocation

Report · Apr 21, 2012

I'm stuck... Googled this to death...

Can't seem to get what I want it to do...

I'm not best with Javascript either...

I want to get GPS Location from device - and basically drop Lat and Long into form fields...

Then I can do whatever after inserting the location etc...

This code below works for a pop up alert location... Which is what I started with...

I want to be able to click button and it just populates the long/lat into the form fields...

Any help is appreciated...

Thx...

script type="text/javascript">
function getLocationConstant()
{
if(navigator.geolocation)
{
navigator.geolocation.getCurrentPosition(onGeoSuccess,onGeoFormLat,onGeoFormLong,onGeoError);
} else {
alert("Your browser or device doesn't support Geolocation");
}
}

// If we have a successful location update
function onGeoSuccess(event)
{
alert(event.coords.latitude + ', ' + event.coords.longitude);
}

function onGeoFormLat(event)
{
var myVal;
myVal = document.getElementById(event.coords.latitude).value;
}
function onGeoFormLong(event)
{
var myVal;
myVal = document.getElementById(event.coords.longitude).value;
}
// If something has gone wrong with the geolocation request
function onGeoError(event)
{
alert("Error code " + event.code + ". " + event.message);
}

// Called when we want to stop getting location updates
function stopGetLocation(event)
{
navigator.geolocation.clearWatch(watchID);
}

/script>

</head>
<body>
<br><br>
Latitude: <input type="text" id="Latitude" name="onGeoFormLat" value="">
<br><br>
Longitude: <input type="text" id="Longitude" name="onGeoFormLong" value="">
<br>

<br><br><br>
<input type="button" value="Get Location" onclick="getLocationConstant()" />
<br><br>

</body>
</html>

I might be missing something, but what's this got to do with CF? It looks like pure client-side stuff to me? Would it be better posted on a JS forum?

I thought u could use javascript with coldfusion etc...

Perhaps we are own worst enemies at times... Worrying about only ColdFusion...

A friend of mine helped me out with this... And solution is below...

Works great... And can be used to push GeoLocation Data for use in ColdFusion...

// If we have a successful location update
function onGeoSuccess(event)
{
document.getElementById("Latitude").value = event.coords.latitude;
document.getElementById("Longitude").value = event.coords.longitude;

}

// If something has gone wrong with the geolocation request
function onGeoError(event)
{
alert("Error code " + event.code + ". " + event.message);
}
</script>

</head>
<body>
<br><br>
<cfform action="gps2.cfm" method="post">
      Latitude: <input type="text" id="Latitude" name="Latitude" value="">
<br><br>
      Longitude: <input type="text" id="Longitude" name="Longitude" value="">
<br><br>
                 <input type="button" value="Get Location" onclick="getLocationConstant()"/>
<br><br>
<input type="submit" value="Add GPS Location" class="small">
</cfform>
<br><br><br>

</body>
</html>

Well of course... one can use Flash with CF as well, but one would be daft to ask a Flash question on a CF forum.

If you want an answer to a JS question, the best place to ask it would be on a JS forum. That's what I meant.

That's a bit of a daft thing to say. Just because we happen to use a bunch of different technologies in the course of arriving at a solution doesn't mean a forum for one of the technologies is the best approach to getting solutions for all of them.
