"Try Google" userscript for DuckDuckGo

I love DuckDuckGo. Ninety-nine percent of the time, it gives me exactly what I want. But sometimes, I want to consult Google for its results. When DuckDuckGo doesn't come up with anything, it presents you with a link to do this, but with the following userscript, you can get a “Try this search on Google” link all the time!

try-google.user.js
// ==UserScript==
// @match http://duckduckgo.com/*
// ==/UserScript==

(function() {
    var tryGoogleDiv = document.createElement('span');
    tryGoogleDiv.style.opacity         = 0.6;
    tryGoogleDiv.style.backgroundColor = 'black';
    tryGoogleDiv.style.color           = 'white';
    tryGoogleDiv.style.position        = 'fixed';
    tryGoogleDiv.style.top             = '65px';
    tryGoogleDiv.style.left            = '10px';
    tryGoogleDiv.style.zIndex          = 20000;

    var form    = document.getElementById('search_form');
    var inputs  = form.getElementsByTagName('input');
    var q;

    for(var i = 0; i < inputs.length; i++) {
        var input = inputs[i];
        if(input.name == 'q') {
            q = input;
            break;
        }
    }
    tryGoogleDiv.innerHTML = '<a href="http://google.com/search?q='
        + q.value + '" target="_blank" style="color: white">Try this same search with Google!</a>';

    var parent = document.getElementById('content');
    parent.insertBefore(tryGoogleDiv, parent.firstChild);
})();
