The $.param( ) inverse function in JavaScript / jQuery

Question

Given the following form:

<form>
    <input name="foo" value="bar">
    <input name="hello" value="hello world">
</form>

I can use the $.param( .. ) construct to serialize the form:

$.param( $('form input') )

=> foo=bar&hello=hello+world

How can I deserialize the above String with JavaScript and get a hash back?

For example,

$.magicFunction("foo=bar&hello=hello+world")

=> {'foo' : 'bar', 'hello' : 'hello world'}

Reference: jQuery.param( obj ).

You should use jQuery BBQ's deparam function. It's well-tested and documented.
