Chrome jQuery AJAX failing, not a cross-domain issue

Question

I've got some simple JS/jQuery code to make an AJAX call to grab some HTML and shove it into a div on my page. This works fine in Firefox but fails in Chrome.

In the Chrome console I can see the AJAX request shown with a status text of "(failed)" and type "pending".

All the searching I've done has searched is relating to cross-domain issues. This doesn't fit here, I'm running this on a webserver, with a domain name, without a port number appended.

Here's my code sample (you can see I was initially trying to use .load(), same problem):

$('#brochure2012navigation a').click(function(event)
{
    event.preventDefault();

    //$('#brochurePage').load($(this).attr('href'));

    $.ajax({
        url: $(this).attr('href'),
        dataType: 'html',
        success: function(html) {
            $('#brochurePage').html(html);
        },
        error: function (xhr, ajaxOptions, thrownError) {
            console.log(xhr);
            console.log(thrownError);
        },
    });
});

In Chrome's console the logged xhr object looks like this:

Object {readyState: 0, setRequestHeader: function, getAllResponseHeaders: function, getResponseHeader: function, overrideMimeType: function…}
abort: function (a){a=a||"abort",p&&p.abort(a),w(0,a);return this}
always: function (){i.done.apply(i,arguments).fail.apply(i,arguments);return this}
complete: function (){if(c){var a=c.length;n(arguments),j?l=c.length:e&&e!==!0&&(k=a,o(e[0],e[1]))}return this}
done: function (){if(c){var a=c.length;n(arguments),j?l=c.length:e&&e!==!0&&(k=a,o(e[0],e[1]))}return this}
error: function (){if(c){var a=c.length;n(arguments),j?l=c.length:e&&e!==!0&&(k=a,o(e[0],e[1]))}return this}
fail: function (){if(c){var a=c.length;n(arguments),j?l=c.length:e&&e!==!0&&(k=a,o(e[0],e[1]))}return this}
getAllResponseHeaders: function (){return s===2?n:null}
getResponseHeader: function (a){var c;if(s===2){if(!o){o={};while(c=bG.exec(n))o[c[1].toLowerCase()]=c[2]}c=o[a.toLowerCase()]}return c===b?null:c}
isRejected: function (){return!!i}
isResolved: function (){return!!i}
overrideMimeType: function (a){s||(d.mimeType=a);return this}
pipe: function (a,b,c){return f.Deferred(function(d){f.each({done:[a,"resolve"],fail:[b,"reject"],progress:[c,"notify"]},function(a,b){var c=b[0],e=b[1],g;f.isFunction(c)?i[a](function(){g=c.apply(this,arguments),g&&f.isFunction(g.promise)?g.promise().then(d.resolve,d.reject,d.notify):d[e+"With"](this===i?d:this,[g])}):i[a](d[e])})}).promise()}
progress: function (){if(c){var a=c.length;n(arguments),j?l=c.length:e&&e!==!0&&(k=a,o(e[0],e[1]))}return this}
promise: function (a){if(a==null)a=h;else for(var b in h)a[b]=h[b];return a}
readyState: 0
responseText: ""
setRequestHeader: function (a,b){if(!s){var c=a.toLowerCase();a=m[c]=m[c]||a,l[a]=b}return this}
state: function (){return e}
status: 0
statusCode: function (a){if(a){var b;if(s<2)for(b in a)j[b]=[j[b],a[b]];else b=a[v.status],v.then(b,b)}return this}
statusText: "error"
success: function (){if(c){var a=c.length;n(arguments),j?l=c.length:e&&e!==!0&&(k=a,o(e[0],e[1]))}return this}
then: function (a,b,c){i.done(a).fail(b).progress(c);return this}
__proto__: Object

Apologies that this looks a bit messy, but I think the important thing is the status of 0.

Monitoring the logs, the request isn't hitting my server.

I'm really stumped here, I'd appreciate any help!

It is possible that the ajax call gets blocked by the AdBlock Chrome addon.

Some URLs might get blocked, based on the keys on the adblock blacklist. On DevTools Network tab, such requests are marked as 'failed', in status 'pending'
