How can I read the contents of a linked script into a String?

I am able to select a linked script element. Is there a way to read the contents into a string?

I have jQuery available.

It depends if the script is embedded or linked.

For embedded javascript you could do 

var test = $('script').eq( index_here ).text();

For an external javascript file with a source attribute, you could perform an ajax request and get the contents.

You can do ajax request and pass script url (src attribute). Server will return js source. Example:

var script = $('selector');
var src = script.attr('src');

if (src.indexOf('://') == -1) {
    src = document.location.href.substr(0, document.location.href.lastIndexOf('/') + 1) + src;
}

$.get(src, {}, function(data){
    // do something
});

Never tried this before but if you get the script such as 

$(scriptselector).text()

Edited.

Just tried it and it seems to work http://jsfiddle.net/UG3hB/

Edit #2:

As Intersteller_Coder pointed out this will not work with linked jsfiles. You can always request the js file via AJAX.

Yes, just get the innerText or innerHTML from the element reference.
