jquery turn querystring into object
<pre><code>var obj = {
    'key': 'value',
    'cheese':'bacon',
    '&amp;':'&gt;'
};    
var params = $.param(obj)

console.log(params); // key=value&amp;cheese=bacon&amp;%26=%3E
</code></pre>

<p>how do I turn <code>params</code> back into an object? (exactly what it was before)</p>
