$.focus() not working

Question

The last example of jQuery\'s focus() documentation states

$(\'#id\').focus()

should make the input focused (active). I can\'t seem to get

Just in case anybody else stumbles across this question and had the same situation I had - I was trying to set the focus after clicking on another element, yet the focus didn't appear to work. It turns out I just needed an e.preventDefault(); - here's an example:

$('#recipients ul li').mousedown(function(e) {
    // add recipient to list
    ...
    // focus back onto the input
    $('#message_recipient_input').focus();
    // prevent the focus from leaving
    e.preventDefault();
});

This helped:

If you call HTMLElement.focus() from a mousedown event handler, you must call event.preventDefault() to keep the focus from leaving the HTMLElement. Source: https://developer.mozilla.org/en/docs/Web/API/HTMLElement/focus
