Error in IE when loading jQuery

I have two web pages (let's call them site A and B) that are both using the same externally sourced jQuery. Site B is simply a subdomain of site A. In site A, I declare the javascript as:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

Site A has no problems whatsoever.

On site B, I am declaring the jQuery library slightly different but the libary is found and loaded:

`if (typeof jQuery == 'undefined') {
            document.write(unescape("%3Cscript    src='https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js' type='text/javascript'%3E%3C/script%3E"));`

The Problem: In IE 8 and 9, when site B is loading, the Microsoft security error "This page is accessing information that is not under its control. This poses a security risk. Do you want to continue?"

Debugging: After viewing both site A and B in the IE JavaScript debugger, it's clear that A has no problems where as B prompts the user with this alert when the jQuery library has loaded.

Why would loading this library force the prompt on one site, but not the other?

You should really use the DOM instead of using document.write. That will most likely prevent errors like this. Just do it this way:

if (typeof jQuery === 'undefined') {
    var s = document.createElement('script');
    s.src = '//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js';
    s.type = 'text/javascript';
    document.head.appendChild(s);
}

EDIT: Hardy's answer is probably the right solution to this problem, but the point remains that this is almost always a better way to add elements to your page.

Change your site B to use http url to google:

Change this:

https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js

to

http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js

You get that message in IE because of that https creates secure connection and your site is not using https (i assume).
