Detecting IE6 using jQuery.support

Question

Anyone have any ideas on how to test for something specific for IE6 (and not IE7) using jquery.support?

My problem is that IE6 supports :hover psuedo-class only for anchor elements and IE7 does support it for all elements (as FF, Chrome, etc). So I want to do something special in case the browser does not support :hover for all elements... thus I need a way to test for this feature. (don't want to use jQuery.browser). Any ideas?

While it's good practice to check for feature support rather then user agent, there's no simple way to check for something like support of a css property using JavaScript. I recommend you either follow the above posters suggestion of using conditional comments or use jQuery.browser. A simple implementation (not validated for performance or bugs) could look like this:

if ($.browser.msie && $.browser.version.substr(0,1)<7) {
  // search for selectors you want to add hover behavior to
  $('.jshover').hover(
    function() {
      $(this).addClass('over');
    },
    function() {
      $(this).removeClass('over');
    }
}

In your markup, add the .jshover class to any element you want hover css effects on. In your css, add rules like this:

ul li:hover, ul li.over { rules here }
