jQuery Facebox plugin: Focus the popup appearance

问题

I have an HTML page with facebox popup.

This page contains many links and forms, and the popup contains one form. What I want is, when I open the popup, using only keyboard's buttons, to go directly to the form's inputs of the popup with 'tab' button.

Here is a fiddle --> http://jsfiddle.net/tk1jagpb/

$(document).ready(function () {
  $('a[rel*=facebox]').facebox()
})

.popup {
  background-color: mistyrose;
}

<p><a href="#info" rel="facebox">Click to display</a></p>

<div id="info" style="display: none;">
  <p>Popup div</p>
  <p><input type="text" value = "" /></p>
  <p><input type="text" value = "" /></p>
  <p><input type="text" value = "" /></p>
  <p><input type="text" value = "" /></p>
</div>

<p><input type="text" value = "" /></p>
<p><input type="text" value = "" /></p>
<p><input type="text" value = "" /></p>

If it were so, I might use the keyboard without having to click the popup box... It would save my time.

Thanks.

You can listen for the 'reveal.facebox' event which is fired just after the facebox is shown. Once the facebox is shown, just focus the first input field.

$(document).ready(function() {
    $('a[rel*=facebox]').facebox();
    $(document).bind('reveal.facebox', function() {
        $('.popup input:first').focus();
    });
})
