Is it possible to catch net::ERR_BLOCKED_BY_CLIENT?

So on our site we have various searches some of which work fine and return the appropriate results. A few of them however return the javascript error:

Failed to load resource: net::ERR_BLOCKED_BY_CLIENT when I search on
my machine.

I have found out that issue is that I am running AdBlocker in Google Chrome and it is AdBlocker that is causing the problem. Now I know I could just turn AdBlocker off which is fine and I have, but is there a way for me to catch this error in javascript and report to the user why they are not getting any search results?

Ideally I am after something similar to a c# try/catch.

EDIT:
OK, so after some digging around and being pointed in the right direction from the comments below I think I have deduced the issue, hopefully this will help others.

After having read this it looks like what I am trying to accomplish cannot be done using the version of jQuery we are currently running (1.10.x) so I guess the solution is to use a new version of jQuery (2.x) and see if I can catch the error

Unfortunately you cannot catch that error message specifically, but you can catch the error itself:

$.ajax({

  url: 'http://openx.net',

  dataType: 'json',

  success: function( data ) {

    console.log( Success:, data);

  },

  error: function( data ) {

    console.log( Error:, data);

  }

});

Obviously the example isn't requesting JSON, but you can see that it fails and calls the error handler.

These errors are fired by Chrome when, for instance, a plugin like Adblock (as you mentioned) cancels a request.
