Foundation utils is not working in ie8 - internet-explorer-8

Question

I am trying to use Foundation.utils in IE8 but I always get true on small only and false on the rest, for example:
Foundation.utils.is_small_only() = true all the time
Foundation.utils.is_small_up() = false
Of course the above can't happen because if it is small only, then it's for sure small up...
Any fix for that?

Answer 1

Foundation 5 doesn't support IE 8 at all but you can try this.
Quoted from Foundation FAQ:
Why doesn't Foundation support IE7 or IE8? Or: why we don't support a dying species.
This is probably the biggest question we get. Consider this: most of
today's popular browsers automatically upgrade themselves including
Chrome, Firefox and Explorer (starting with 9). IE 8 is the last IE
supported on Windows XP, which Microsoft will officially stop
supporting next year. That played a part in our decision.
Besides that, since Foundation 4, our framework is built mobile-first,
meaning it relies on media queries to layer in more complex layouts
and components. Browsers or devices that don't support media queries
will be restricted to a simple, single-column layout. In some ways,
Foundation 4 better supports IE6-7 insomuch as it provides a mobile
but not entirely broken experience. If IE8 support is important for
your users / customers, you can use Foundation 3.2, which supports
IE8. It's not mobile first but it's good stuff.

Answer 2

I've written my own solution to support utils in ie8.
I built it specific for my use (it could be done much better but why to make the effort? it's only for ie8..), still I believe you can use it, even with minor tweaks.
var win = $(window),
bodyFontSize = parseInt(body.css('fontSize'));
function matchMediaQuery(mediaQuery)
{
var winWidth = win.outerWidth(),
winHeight = win.outerHeight(),
mediaQuerySizes = mediaQuery.match(/\d+\.?\d*em/g);
if (mediaQuerySizes == null)
{
return true;
}
else
{
mediaQuery = mediaQuery.replace(/^(only screen)( and )?/,'').replace('min-width:',winWidth + '>=').replace('max-width:',winWidth + '<').replace('min-height:',winHeight + '>=').replace('max-height:',winHeight + '<').replace('orientation:landscape',winHeight + '>' + winWidth).replace(' and ',' && ').replace(' or ',' || ');
for (var i = 0, len = mediaQuerySizes.length; i < len; i++)
{
mediaQuery = mediaQuery.replace(mediaQuerySizes[i],parseInt(mediaQuerySizes[i])*bodyFontSize);
}
return eval(mediaQuery);
}
}
$.each(Foundation.media_queries, function(key, value)
{
eval('Foundation.utils.is_' + ((key.indexOf('-') > -1) ? key.replace('-','_') : key + '_up') + ' = function() { return matchMediaQuery("'+value+'"); }');
});
