We will use javascript to build our app, so we will create an external
javascript file, in the same location with the name javascript.js that we will
insert in our container with:
<script src="javascript.js"></script>
First we will get the geographic coordinates of the user. Since all this
will be inside jQuery we will start by declaring a function inside a jQuery
wrapper, so this will execute when the document is ready.
$(function () {
// jQuery methods go here...
});
