I have a normal html site, it defines a variable called myVar. This is the declaration:

var myVar = something_that_is_set_dynamically;

Now I have a js file and I need to get the value of myVar in that file. How would I do that?

Thanks!

    Make sure you have added the javascript file after you have declared your myVar.

    For instance:

    <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
    <meta http-equiv="Content-Type" content="text/html;charset=UTF-8" />
    <title></title>
</head>
<body>
    <script type="text/javascript">
        var myVar = "foobar";
    </script>

    <script type="text/javascript" src="yourJsFileUses-myVar.js"></script>

    <!-- you cannot declare myVar here, because "yourJsFile.js" is already
         being executed, so you have to declare your myVar before you include
         your javascript file -->
</body>
</html>
