The code below works as expected in FF but not in IEs...

$(document).ready(function() {



    $('div.facet_dropdown select').live('change', function() {

        var changed_facet = $(this).attr('id');

        var facets = $('select', $(this).closest('form'));

        var args = window.location.href.split('?')[0] + '?ajax=1';

        var clear = false;

        for(var i = 0; i < facets.length; i++) {

            var ob = $(facets[i]);

            var val = ob.val();

            if(clear) {

                val = '';

            }

            args += '&' + ob.attr('id') + '=' + val;

            if(ob.attr('id') == changed_facet) {

                clear = true;

            }

        }



        $.getJSON(args, function(json) {

            for(widget_id in json) {

                var sel = '#field-' + widget_id + ' div.widget';

                $(sel).html(json[widget_id]);

            }

        });



    });



});
