Object.toQueryString(object) → String

object (Object): The object whose property/value pairs will be converted.

Turns an object into its URL-encoded query string representation.

This is a form of serialization, and is mostly useful to provide complex parameter sets for stuff such as objects in the Ajax namespace (e.g. Ajax.Request).

Undefined-value pairs will be serialized as if empty-valued. Array-valued pairs will get serialized with one name/value pair per array element. All values get URI-encoded using JavaScript's native encodeURIComponent function.

The order of pairs in the serialized form is not guaranteed (and mostly irrelevant anyway) — except for array-based parts, which are serialized in array order.
