[jQuery] jQuery 1.2 - Serialize a form as JSON

[Christoph Roeder]

Hello,

I'm trying to serialize a form with select-fields defined as multiple,
e.g.:
~~~~~~~~~~~~~
<select multiple="multiple" name="test[]">
    <option value="one" selected="selected">One</option>
    <option value="two">Two</option>
    <option value="three" selected="selected">Three</option>
</select>
~~~~~~~~~~~~~

When I now try this:

~~~~~~~~~~~~~
$("select").serialize();
~~~~~~~~~~~~~

or this:

~~~~~~~~~~~~~
$("select").serializeArray();
~~~~~~~~~~~~~

I get an empty string resp. array.

But I should get this:

~~~~~~~~~~~~~
test[]=one&test[]=three
~~~~~~~~~~~~~

resp. this:

~~~~~~~~~~~~~
{
  test: ["one", "two"]
}
~~~~~~~~~~~~~

Whats wrong with my code?

PS: I'm currently using Prototype with PHP in the backend, there it
just works fine.
