submit a form with jQuery after delay

问题

I have a very simple form in HTML and I'd like to submit this form after 2000ms (of delay) from when the document is ready, without push the submit button. How can I do this with a jQuery script?

<form id="my_form" action="NextPage.php" method="post">
    <fieldset class="my_fieldset">
        <input type="radio" name="my_radio" value="value_A" checked="checked"/>Value A<br/>
        <input type="radio" name="my_radio" value="value_B"/>Value B<br/>
    </fieldset>
        <input type="submit" value="Send" id="Send"  tabindex="110">
</form>

I can't find a command to say "when ... submit the form".

回答1:

You need to wait with delay() function and then submit() the form itself:

$(function() {
    $('#my_form').delay(2000).submit();
});

回答2:

$(function() {
  setTimeout(function() {
   $('#my_form').submit();
  }, 2000);
});
