How to use variable in another file?

Question

I want to pass an variable to another file. I use the lat variable in new js file but not working.

In address.php:

<div class="saveaddress">Click me</div>

<script>
    var lat;
    var lng;
    function displayLocation(position) {
        var lat = position.coords.latitude;
        var lng = position.coords.longitude;
    } 
</script>
.
.
.
<script src="js/save.js"></script>

save.js file:

$('.saveaddress').click(function(){
    alert(lat);
}

How can I do that? (How can I do that? (I followed other questions but not worked for me.)

Did you try not redclaring lat and lng? Change var lat = position.coords.latitude; to lat = position.coords.latitude; and see if that works. — But I'm Not A Wrapper Class

You should try fixing the scope of the variable by not redclaring:

var lat;
var lng;
function displayLocation(position) {
    lat = position.coords.latitude;
    lng = position.coords.longitude;
}

Alternatively, you could add the variable to the window:

function displayLocation(position) {
    window.lat = position.coords.latitude;
    window.lng = position.coords.longitude;
}

Then:

$('.saveaddress').click(function(){
    alert(window.lat);
}
