I have a form with a <select> on the page. when the user selects an option, I want the form to submit itself. How can I do this?

You could subscribe for the .change() event on the dropdown and invoke the .submit() method of the containing form:

<form action="/" method="post">
    <select id="myDropdown">
        <option value="1">item 1</option>
        <option value="2">item 2</option>
        ...
    </select>

    ...
</form>

and then:

$(function() {
    $('#myDropdown').change(function() {
        $(this).closest('form').submit();
    });
});
