Prblem with variables

[miguel21op]

Sorry guys I'm a rookie on JS and I have the problem explained below: how do I pass the values of vars "lat1" and "long1" to outside the function and assign them to wp[0] as shown?

(No problem with wp[1] that I get from another file).

Thanks,

Miguel

<script type="text/javascript">
	
	navigator.geolocation.getCurrentPosition(
 	function (pos){
        lat1 = pos.coords.longitude;
	long1 = pos.coords.latitude;
});
	var lat2 ="<?php echo $_SESSION['lat']; ?>";
	var long2 ="<?php echo $_SESSION['long']; ?>";	
	
         var wp = new Array(2);
	 wp[0] = lat1 + "," +long1;
	wp[1] = lat2 + "," +long2;
	
	inicio = (wp[0]);
	destino = (wp[1]);

You probably just need to define lat1 and long1 as global variables. Then you can assign their values from within the geo function, and still retrieve the values to populate your array.

Try declaring the vars directly after your opening script tag to make them global:

  <script type="text/javascript">
    var lat1;
    var long1;
    navigator.geolocation.getCurrentPosition(
// ... resume your code

That solution you gave to me I tried before but no value passes to the variable.

If I try to echo it outside the function like:

document.write(lat1);

the output I get is "undifined"; although I get the correct value if I put the same statement inside the function

[rnd me]

are you sure that getCurrentPosition() has completed and called the callback by the time you look at lat1?

it looks like you check lat1 immediately, quite possibly before the call back sets the values you are looking for.

that's why it works in the callback, where it waits for the value.

whatever you wanted to do with wp[], do it in the callback.

Yes. I think that may be the problem...
