Doesn't work in IE8.

[jimmyye]

typeof XMLHttpRequest === 'function' // normal browsers
typeof XMLHttpRequest === 'object'   // IE8

[jonvuri]

Seems that XMLHttpRequest isn't defined (at least, the normal way) in IE7/8: http://stackoverflow.com/questions/2363212/window-xmlhttprequest-is-undefined-in-ie7-ie8

We could also check for ActiveXObject but maybe it would be better to switch to a proper AJAX micro-lib?

i am thinking safari has the same problem

[MartinKolarik]

@violinchris The problem with Safari has been solved (#9). We'll need to use ActiveXObject for IE 8 though.

[Rich-Harris]

Maybe the best solution is to expose the get() function so that it can be overwritten. That way if someone needs to support IE8 they can do

Ractive.load.get = function ( url ) {
  return new Ractive.Promise( function ( fulfil, reject ) {
    // use library of choice
    var request = someAjaxLib({
      url: url,
      onload: function () {
        fulfil( request.response );
      },
      onerror: reject
    });
  });
};

It'd be a shame to have to include another lib just to support a handful of laggards.

Or maybe we have two build targets with different requirejs configs - i.e. add a sibling to compile in this file where the paths object has something like

get: 'utils/get-legacy'

Then we could include a proper AJAX micro-lib (I assume, given that there's so many of them, that there's a bit of work involved in getting ActiveXObject to behave? Never looked into it).

@Rich-Harris I'm not 100 % sure, but I think that ActiveXObject would work exactly like XMLHttpRequest. If that was not the case then I think having legacy build would be the best option.
