Force http protocol in Javascript file from local protocol

We are using HTML5 to develope an phone app, which means that our local protocol on the phone is file://. We are trying to include Opentable's widget on our page for now. But their widget JS link looks like:

<script type='text/javascript> src='//secure.opentable.com/widget/reservation/loader?rid=27763&domain=com&type=standard&theme=standard&lang=en&overlay=false&iframe=true'></script>

Note that it starts with


So it will get our file:// protocol automatically. But even I change it to


It still does not work on local. I noticed that in their JS source, they still used "//" which will somehow still get our "file://" protocol.

Here is the error after I change the link to https://secure.opentable.com/...

Failed to load resource: The requested URL was not found on this


I noticed that in the console it looks like:

enter image description here

How can I make it work for a local environment?



Maybe this will work:

$(document).ready(function() {
    $("iframe[src^='//www.opentable.com']").attr('src', function(i, oldsrc) {
        return "https:" + oldsrc;

It waits until the document is ready, which should be after the new IFRAME is added to the DOM, then it replaces its src with one with the https: protocol.
