Workaround for file input label click (Firefox)

thank you for this q&a... helped me out.

my variation of @marten-wikstrom's solution:

if($.browser.mozilla) {
  $(document).on('click', 'label', function(e) {
    if(e.currentTarget === this && e.target.nodeName !== 'INPUT') {
      $(this.control).click();
    }
  });
}

notes

• using document.ready ($(function() {...});) is unnecessary, in either solution. jQuery.fn.live takes care of that in @marten-wikstrom's case; explicitly binding to document does in my example.
• using jQuery.fn.on... current recommended binding technique.

• added the !== 'INPUT' check to ensure execution does not get caught in a loop here:

  <label>
    <input type="file">
  </label>
  

  (since the file field click will bubble back up to the label)

• change event.target check to event.currentTarget, allowing for initial click on the <em> in:

  <label for="field">click <em>here</em></label>
  

• using the label element's control attribute for cleaner, simpler, spec-base form field association.

I came up with a feasible workaround:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
<script type="text/javascript">
    $(function () {
        $("label").click(function () {
            $("#input").click();
        });
    });
</script>
<label for="input">Label</label><input type="file" id="input"/>

Quite strange that FF allows you to simulate a click on a file input. I thought that was considered a security risk...

UPDATE: This is a generic workaround:

<script type="text/javascript">
    $(function () {
        if ($.browser.mozilla) {
            $("label").live("click", function (event) {
                if (event.target == this) {
                    $("#" + $(this).attr("for")).extend($("input", this)).first().click();
                }
            });
        }
    });
</script>
