Why isn't this simple bit of jQuery getJSON working in IE8?

Question

I\'ve got a very standard AJAX request:

$.getJSON(\'/products/findmatching/38647.json\', {}, function(JsonData){
  var tableHtml = \'\';
  var x;

  for (x i

You have to use check browser and version for IE8+, then use the XDomainRequest() if msie8+.

This will return a JSON String, must use jQuery.parseJSON() to create the JSON object…

Don't use getJSON!

Here's my example:

if ($.browser.msie && parseInt($.browser.version, 10) >= 8 && window.XDomainRequest) {
        // Use Microsoft XDR
        var xdr = new XDomainRequest();
        xdr.open("get", reqURL);
        xdr.onload = function() {
            var json = xdr.responseText;
            json = $.parseJSON(json);

            $.each(json.results, function(i, val) {
                    console.log(val.formatted_address);
                    var locString = val.formatted_address;
                    $.each(val.address_components, function(x, comp) {

                        if($.inArray("postal_code", comp.types) > -1) {
                            //alert("___" + comp.types);
                            zipmap[locString] = comp.short_name;
                        }

                    });

                    suggestions.push(val.formatted_address);
                });

            //alert(json.results);
        }
        xdr.send();
        add(suggestions); 
    }else {
        $.getJSON(reqURL, function(data) {

            var isZIP = new Boolean;
            console.log(data.results);
            $.each(data.results, function(i, val) {
                console.log(val.formatted_address);
                var locString = val.formatted_address;
                $.each(val.address_components, function(x, comp) {

                    if($.inArray("postal_code", comp.types) > -1) {
                        console.log("___" + comp.types);
                        zipmap[locString] = comp.short_name;
                    }

                });

                suggestions.push(val.formatted_address);
            });

            add(suggestions);  

        });
    }

requrl is the URL which you are making a request to.

Done!
