Reset to default
455 
function getURLParameter(name) {
  return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search) || [null, ''])[1].replace(/\+/g, '%20')) || null;
}

So you can use:

myvar = getURLParameter('myvar');

Thanks for a great answer. Added an edit to it to take into account the edge case of parameters with no values.
@DeanMeehan awesome if it "just works" but I would not say that it is a simple solution considering the readability of regex expressions
Does this work if there is a hash tag in the URI? If there is a #something in Chrome, then you have to use window.location.hash instead of window.location.search...
Would have upvoted if a) explanation of what's going on and b) passes JSHint validation: currently, the [, ""] construction is invalid
How can you get values for an array parameter such as test.com?arr[]=vxcbcvb%20cvbvbcvb
