JQM: $.mobile.changepage not loading external .JS file

I am having a weird problem when trying to load an external JS file in a page which is loaded using $.mobile.changepage().

Following is my directory structure:

|_ /html
|   |_ conflist.html
|   |_ newpage.html
|_ /common
|   |_ jquery-1.7.2.min.js
|   |_ jquery.mobile-1.2.0.min.js
|   |_ jquery.mobile-1.2.0.min.css
|_ /platform
    |_ dummy.js

Here are the codes for conflist.html and newpage.html.

First, conflist.html:

<!DOCTYPE HTML>
<html>
<head>
    <title>ConferenceToGo</title>
    <meta name="viewport" content="width=device-width, initial-scale=1" /> 
    <link rel="stylesheet" href="../common/jquery.mobile-1.2.0.min.css" />
    <script type="text/javascript" charset="utf-8" src="../common/jquery-1.7.2.min.js"></script>
    <script type="text/javascript" charset="utf-8" src="../common/jquery.mobile-1.2.0.min.js"></script>
    <script type="text/javascript" charset="utf-8">
        function changePage() {
            $.mobile.changePage("newpage.html", { transition: "slide" });
        }
    </script>
</head>
<body>
<div id="firstpage" data-role="page">
    <div data-role="content">
        <input type="button" onclick="changePage()" value="Change Page (JQM)" /><br />
    </div><!-- /content -->

</div><!-- /page -->

</body>
</html>

Next, newpage.html:

<!DOCTYPE HTML>
<html>
<head>
    <title>ConferenceToGo</title>
    <meta name="viewport" content="width=device-width, initial-scale=1" /> 
    <link rel="stylesheet" href="../common/jquery.mobile-1.2.0.min.css" />
    <script type="text/javascript" charset="utf-8" src="../common/jquery-1.7.2.min.js"></script>
    <script type="text/javascript" charset="utf-8" src="../common/jquery.mobile-1.2.0.min.js"></script>
</head>
<body>
<div id="newpage" data-role="page">
    <script type="text/javascript" charset="utf-8" src="../platform/dummy.js"></script>
    <script type="text/javascript" charset="utf-8">
        console.log("Inside test_newpage.html");
        var objDummy = new Dummy();
        objDummy.toString("test param");
    </script>
    <div data-role="content">
        <p>This is a new page !!</p>
    </div><!-- /content -->

</div><!-- /page -->

</body>
</html>

Finally, dummy.js:

var Dummy = function () { };
Dummy.prototype.toString = function (param) {
    console.log("String representation of 'Dummy', got param: " + param);
};

console.log("Loaded dummy.js");

Problem:

Wondering, why do I see this behavior? Why isn't the external js file loaded when it is placed in another folder and the relative path is given?

Update: I checked and this also works if I put dummy.js in a subfolder inside the html folder. Just can't have it outside it seems, unless I am missing something.

I think the reason might be the relative path of your js. I found that if you are using $.mobile.changePage(); only contents in the target page between the will be loaded, which means all the header content in target page will be ignored/not loaded. And when you reference js in the on your target page, the relative path should be base on the target html. and the "../" seems not working in this case.

Change your relative URLs to absolute ones. This will make sure you are referencing the correct file every time.

Your external page would look like this for example:

<!DOCTYPE HTML>
<html>
<head>
    <title>ConferenceToGo</title>
    <meta name="viewport" content="width=device-width, initial-scale=1" /> 
    <link rel="stylesheet" href="/base/common/jquery.mobile-1.2.0.min.css" />
    <script type="text/javascript" charset="utf-8" src="/base/common/jquery-1.7.2.min.js"></script>
    <script type="text/javascript" charset="utf-8" src="/base/common/jquery.mobile-1.2.0.min.js"></script>
</head>
<body>
<div id="newpage" data-role="page">
    <script type="text/javascript" charset="utf-8" src="/base/platform/dummy.js"></script>
    <script type="text/javascript" charset="utf-8">
        console.log("Inside test_newpage.html");
        var objDummy = new Dummy();
        objDummy.toString("test param");
    </script>
    <div data-role="content">
        <p>This is a new page !!</p>
    </div><!-- /content -->

</div><!-- /page -->

</body>
</html>

Where /base/ is a top-level directory on your domain.

try to put your <script src="../platform/dummy.js"></script>into the head instead of the body... and: you do not need type="text/javascript" charset="utf-8"anymore...

<head>
    <title>ConferenceToGo</title>
    <meta name="viewport" content="width=device-width, initial-scale=1" /> 
    <link rel="stylesheet" href="../common/jquery.mobile-1.2.0.min.css" />
    <script src="../platform/dummy.js"></script>
    <script src="../common/jquery-1.7.2.min.js"></script>
    <script src="../common/jquery.mobile-1.2.0.min.js"></script>
</head>
