How to append a jQuery script to head tag

I see 2 problems with this code:

1) You are using jQuery syntax in your script block to add a reference to load jQuery? This will NOT work unless you already have a copy of jQuery loaded somewhere and are trying to use this code to update it to something else for some reason.

2) I see you are escaping the " like so: \" in your first example. You DO NOT need to do that in jQuery, assuming issue 1 is not really an issue or resolved. jQuery will properly handle double quotes inside a single quote or vice versa.

How Do I Add jQuery To Head With JavaScript?

A script loads asynchronously. This means its contents are not directly available after appending the element.

Use onload instead:

script = document.createElement('script');

script.onload = function() {
    // jQuery is available now
};

script.type = 'text/javascript';
script.src = 'https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js';

head.appendChild(script);

How to append script /script in JavaScript?

Try this:

var s = document.createElement("script");
s.type = "text/javascript";
s.src = "http://somedomain.com/somescript";
$("head").append(s);

Note that the script will load and you can access the variables inside it, but you wouldn't see the actual <script> tag in the DOM.
