Passing variables via GET from one page to javascript on another page

1

Still just getting my head around PHP/Javascript.

I’m trying to get some values from page 1 to page 2.

On page 1, I have a link:

<a href=“userdata_map.php?lat=43.471079&lng=-89.744310”>Edit This Map</a>

On page 2, I have an initialize function that contains this:

var latlng = new google.maps.LatLng(parseFloat(<?php $_GET[“lat”]; ?>), parseFloat(<?php $_GET[“lng”]; ?>));

However this doesn’t seem to be working. The source of page 2 just shows this:

var latlng = new google.maps.LatLng(parseFloat(), parseFloat());

How do I make this work?

Thanks.
