jQuery .focus() and .blur() not working in Chrome or Safari

Question

I am creating a survey form that needs to have each question and set of answers highlighted (by changing the background color) when the user focuses on them. .focus() and .blur() both work in Firefox and IE, but not entirely in Safari and Chrome. I also tried .focusin() and .focusout() with the same results. EDIT: Clicking does not fire the focus event, but tabbing through the input fields does. I say not entirely because it works for text inputs, select inputs and textarea inputs; but not radio and checkbox inputs.

$(document).ready(function()
 {
    $("form li").focusin(function()
  {
   $(this).addClass("over");
  }).focusout(function()
  {
     $(this).removeClass("over");
  });
 });

This is being applied to blocks of html similar to this:

<li>
    <label for="webmail" class="desc">Email</label>
    <input type="text" name="webmail" id="webmail" />
</li>
<li>
    <label for="business" class="desc">Purpose of your Charter Flight:</label>
    <div>
        <span>
            <input type="radio" name="purpose" id="business" class="radio" />
            <label class="choice" for="business">Business</label>
        </span>
        <span>
            <input type="radio" name="purpose" id="pleasure" class="radio" />
            <label class="choice" for="pleasure">Pleasure</label>
        </span>
    </div>
</li>

I tried messing around with toggles, but I am looking for a more elegant solution that doesn't involve using convoluted logic to make it work. Any ideas?

Answer 1

I also came across this problem a long time ago, and oddly enough it was a radio button giving me the grief.

Try using jQuery.change() instead, here's a working example from that problem I had

$("input#zendesk-dropbox-askedbefore, input#zendesk-dropbox-newhere").change(function() {
    $("label#zendesk-dropbox-label-askedbefore, label#zendesk-dropbox-label-newhere").toggleClass('zendesk-dropbox-label-highlight');
});

In case it's unclear from my crazy use of ID names, input#zendesk-dropbox-askedbefore & input#zendesk-dropbox-newhere are both radio buttons.

I thought about it on the drive home last night and figured it out on my own, it may not be the most elegant solution, but it certainly works.

$(document).ready(function()
    {
       $("textarea, input, select, .radio, .checkbox").click(function()
        {
            $("form li.over").toggleClass("over");
            $(this).parents("li").toggleClass("over");
        });
    });

Thanks anyway!
