Update forms / Bootstrap fields based on URLs

If the URL is ?state=A&district=B&..., then $('.my-form').update(url) should update the inputs (include select, textarea, Bootstrap dropdowns, etc) with matching keys to have the associated values.

For example,

<form class="my-form">
  <select name="state">...</select>
  <input name="district">
</form>

... should change to show the state as A and the district as B
